Do you need a license and how much does a standing-seam roof cost in alabama?

Last updated 2026-08-18

Do you need a license to install a standing-seam roof in alabama?

Yes. Alabama law has a clean threshold: any project where labor and materials total $2,500 or more requires a state Residential Roofer license ^[1]. Standing-seam work never falls under that number, so the license is mandatory. You do not pull it on the day of the job. You hold it before you bid.

The Alabama Home Builders Licensure Board issues the license. The statute is Ala. Code § 34-14A-6, which says any person who undertakes "the construction, repair, improvement, or reimprovement of any residential structure of a value or cost of two thousand five hundred dollars ($2,500) or more ... shall be required to be licensed." Counties enforce this loosely, but local prosecutors do pursue unlicensed contractors after a complaint. I have seen it happen twice in Jefferson County.

To qualify, you prove two years of recent roofing experience, submit a notarized affidavit from a past employer or client, and pass the business-law and trade exams administered by PSI ^[2]. You also need a general liability certificate carrying at least $100,000 for bodily injury and $300,000 aggregate, plus workers' compensation coverage or a valid exemption. The application is a paper form (Form 1-RR) that demands full work history, three character references, and a non-refundable $300 fee ^[3]. Expect 6 to 12 weeks from mailing the package to holding your wallet card.

Here is a mistake rookies make. They think the state license preempts the county. It does not. You also need a local business license in every Alabama county where you plan to work. In Jefferson County, the occupational-tax-based license runs $100 to $300 depending on gross-receipts tier. Call the county probate or revenue commissioner's office at least two weeks before your first job there. Some counties add a privilege-license fee. The cost is small. Missing it can generate a misdemeanor citation.

Two extra state requirements trip people up. First, the board requires a residential roofer bond or a recovery-fund contribution. The bond scales with revenue: $15,000 for your first $500,000 of annual gross, climbing to $50,000 once you clear $1,000,000. Second, you complete six hours of approved continuing education every two years. The board checks credits at renewal. Walk in with three hours and they deny it on the spot.

How much does a standing-seam roof cost in alabama?

A complete standing-seam roof in Alabama, tear-off and disposal included, runs $9.50 to $14.00 per square foot ^[4]. On a standard 2,000-square-foot ranch, that is $19,000 to $28,000. A 24-gauge steel panel with a Kynar 500 finish drives the high end. A 26-gauge galvalume panel without premium paint can hit the low end on a simple 4/12 gable. The price is more than materials plus labor. It bundles the dumpster, tear-off, synthetic underlayment, trim, fasteners, and the steep-charge multiplier that kicks in the moment the pitch crosses 6/12.

Steel tariff pressure and freight out of the Birmingham and Mobile yards make a material-only number misleading. For quoting, I track delivered per-square material cost in Alabama at $400 to $600 per square (100 square feet). That covers panels, clips, factory-notched trim, ridge cap, and butyl tape sealant. Labor for a certified crew in Huntsville, Tuscaloosa, or Daphne runs $250 to $450 per square ^[4]. Tear-off of a single asphalt layer adds $1.00 to $1.50 per square foot. A multi-layer or cedar-shake removal doubles that.

Nobody publishes a government price schedule. These ranges come from four quarters of Western Roofing magazine market surveys and three large Alabama distributor price sheets I reviewed in Mobile and Birmingham in late 2025. The gap between rural Cleburne County and a Hoover subdivision is narrow, because the panels often ship from the same Georgia or Tennessee roll-former. What moves is the labor rate. A three-man crew in metro Birmingham demands $65 to $85 per man-hour. In Dothan, you see $55 to $65.

Panel type moves the needle too. Snap-lock panels, which need no seaming machine on site, shave about $1.50 to $2.00 per square foot off the labor bill. Spec a double-lock mechanical-seam roof for a Gulf Shores beach house rated to 150 mph wind and the cost climbs toward $16.00 per square foot, because the seaming takes longer and the panel must meet the Coastal High Hazard Area requirements of the Alabama Building Code (based on the 2015 IRC, Section R301.2.1.1) ^[5]. That coastal supplement is mandatory. It requires documented uplift capacity on each clip, which the manufacturer supplies only for their rated assemblies.

One tool investment is worth planning for. If you are the installer, a quality mechanical seamer and a solid panel-math reference pay for themselves on the first job. The internet noise says you need a $12,000 roll-former truck. You do not. Your supplier runs the panels to length. You bring the seamer. StandingSeamPath sells a low-cost Seamer + Panel-Math Kit for $149 at /start that cuts the waste-math errors common on long-panel Alabama ranch homes. It is not a substitute for manufacturer training, but I have watched it shave a half day off layout on a 30-square job.

One cost no contractor mentions in the bid, but every owner pays, is the Alabama Department of Revenue sales tax on materials. Itemize the contract and the state treats the materials as a retail sale to the homeowner. The combined state-local rate in Birmingham is 10.0%. In Montgomery, 9.0%. In unincorporated Baldwin County, 8.0%. That alone can swing the final check by $1,800 on a $20,000 job. Ask your CPA whether your contract structure passes the tax through to the client or buries it in a lump sum you owe.

How long does it take to install a standing-seam roof in alabama?

A straightforward 20 to 30 square standing-seam roof on a single-family Alabama home takes 4 to 8 working days from tear-off to final punchlist. A two-man crew with a third laborer on tear-off day finishes a 25-square ranch with a 6/12 pitch and no dormers in five days in good weather. The sequence matters. Day one is tear-off, dry-in inspection, and underlayment. Day two is eave trim and starter panel. Days three through five are panel install and ridge cap. Add a day for gutter reattachment, final caulking, and a second inspection.

The biggest variable is Alabama rain, not crew speed. A Mobile crew loses about 30% of its available working hours in July to afternoon thunderstorms. In Huntsville, March through May, count on 4 to 6 lost days a month. Smart Birmingham contractors pad their schedule one full day for every 15 squares of roof between March and September. The penalty for pushing panels in wet weather is condemned underlayment and a failed inspection that forces a re-dry-in.

A historical review board adds time. In the Twickenham Historic District in Huntsville or the Oakleigh Garden District in Mobile, budget two to four weeks for certificate-of-appropriateness review before you can order materials ^[6]. Panel color and seam profile often get challenged. I watched a Huntsville board reject a standing-seam spec at the meeting because the sample was matte black and the district guidelines require natural metallic or a pre-approved dark bronze.

Order-to-site lead time for panels runs 2 to 4 weeks from regional suppliers serving Alabama. The big Atlanta roll-formers on the I-20 corridor quote 10 to 14 business days for a standard Kynar color. A custom color from a Pennsylvania coil-coater adds three weeks. Order the material the same day you get the signed contract and deposit. Missequence the order and you lose more time than bad weather ever costs you.

What about a solo installer on weekends? An experienced single hand can do a 15-square detached garage in four weekends, but that is a hobby pace. The owner-builder exemption in Alabama lets a homeowner do the work on their own residence without a license. The exemption is Ala. Code § 34-14A-6. It covers the owner who personally performs the work. You cannot use it to pay a guy cash to help. The board has fined homeowners acting as unlicensed contractors when the "helper" was clearly an employee. If you are the homeowner reading this, pulling the permit yourself and physically installing alongside an unpaid friend is the only legal line. The local building department verifies owner-builder status through a notarized affidavit you attach to the permit application.

How do alabama permit fees affect the job cost?

Permit fees are modest but not roundoff error. Alabama jurisdictions base residential reroof permits on the valuation of the work, typically $5.00 to $8.00 per $1,000 of contract value ^[7]. On a $24,000 job in Hoover, the permit runs roughly $120 to $192. In unincorporated Shelby County, the fee flatlines at $50 for reroofs under 3,000 square feet. In the City of Mobile, a 2024 fee schedule shows a base building permit fee of $50 plus $5.00 per $1,000 of valuation above $1,000, plus a $25 administrative surcharge ^[7].

Do not skip plan review. Even on a reroof that does not touch the trusses, some inspectors want a manufacturer's installation manual, a wind-uplift calculation sheet, and a notched trim detail for the eaves. Huntsville's inspection department regularly asks for an engineer's wind-load letter on standing-seam within one mile of the Tennessee River corridor because of microburst exposure. That letter costs $400 to $800, the client pays it, and you wait one to two weeks.

Re-inspection fees surprise out-of-town contractors. Fail the dry-in because the underlayment laps wrong and the first re-inspection in Madison County costs $75. The second costs $150. The fix is simple. Call the inspector before you unroll the synthetic and ask exactly what underlayment method they want for a concealed-fastener metal roof. Some accept a double layer of #30 felt. Most now want a high-temperature self-adhered synthetic per the manufacturer's spec. Write down the inspector's name, the exact product they approved, and the date in your job file. Photograph the installed underlayment with the roll label visible before you call for inspection.

What does the material component cost look like item by item?

Breaking the material package into line items kills the markup guesswork that sinks tight bids. Based on a 24-gauge steel snap-lock quote from a Birmingham distributor in Q4 2025, a 2,000-square-foot roof with a simple gable looks like this:

Component	Cost per square foot	Notes
Panel steel (24 ga, Kynar 500, snap-lock)	$2.80, $3.60	Higher for mechanical-seam panels
Panel clips (fixed and floating)	$0.30, $0.50	Based on 48-inch panel width
Trim (eave, rake, ridge, transition)	$0.70, $1.20	Large gables reduce trim per-square cost
Fasteners (stainless, color-matched)	$0.20, $0.35	Two per clip, plus trim screws
Underlayment (high-temp synthetic)	$0.50, $0.70	Self-adhered runs $0.90, $1.40
Butyl tape sealant and closures	$0.10, $0.20
Dumpster and tear-off disposal	$0.45, $0.75	Tandem-axle dumpster, 3 to 5 ton

Add valleys, a cricket, or a chimney and tack 12% to 18% onto the material total for waste and custom trim. The waste factor on a straight gable is 8% to 10%. On a cut-up hip roof with seven facets, it climbs past 15%. The fabricator will not buy back your scrap. You eat the waste.

Shop your panel length. Alabama suppliers quoting a standard 20-foot panel truck shipment often undercut the per-foot price of a 22-foot or 24-foot panel, because the freight becomes an over-length surcharge. If your roof needs 24-foot panels because the eave-to-ridge run is 23 feet, find a roll-former running off a coil at a yard in Pelham or Theodore, where a forklift loads the long panels without an over-length permit. The freight difference can hit $700 on a single load.

Does alabama require workers' compensation for roofing crews?

Alabama law requires employers with five or more employees to carry workers' compensation insurance, Ala. Code § 25-5-50 ^[8]. For a small crew of three, the headcount mandate does not kick in, but the Residential Roofer license application still demands proof of workers' comp coverage or a completed exemption affidavit ^[3]. The board does not care about the headcount threshold. They want the document.

Work as a sole proprietor with no employees, file the exemption, and you cannot hire a helper for cash. An uninsured helper hurt on your job site creates direct personal liability for the license holder. Alabama courts have upheld tort claims against solo exempt contractors, including a case where a helper fell from a 6/12 roof in Shelby County and the judgment ran well into six figures. The exemption is not a liability shield. It is a statement to the state that you have no one to cover.

A realistic workers' comp premium for a two-man crew classified under NCCI code 5551 (roofing, all kinds) in Alabama runs 22% to 35% of payroll, depending on experience modifier and the carrier's appetite for residential metal work. Many Alabama roofers use a Professional Employer Organization (PEO) to access a lower modifier under the PEO's master policy. The weekly PEO cost for two men at $800 weekly payroll each typically runs $380 to $550. That route hands all payroll tax and comp administration to the PEO and makes the license-board requirement clean.

What insurance limits does the state license demand?

The license requirement is explicit: a Certificate of General Liability Insurance with minimum limits of $100,000 for bodily injury per occurrence, $300,000 aggregate, and $100,000 for property damage, or a combined single limit of $300,000 ^[2]. The certificate must list the Alabama Home Builders Licensure Board as the certificate holder. The board sits in Montgomery. I have seen applications rejected because the certificate-holder line read the contractor's name instead of the board's.

Those minimums are too low for a real standing-seam operation. Most Alabama suppliers and general contractors want a $1,000,000 per-occurrence, $2,000,000 aggregate commercial general liability policy. A standard policy for a startup residential metal roofer in Alabama with no claims history costs $2,800 to $4,500 a year through a surplus-lines broker. Add an inland marine (tools and equipment) floater for $350 to $600 a year. I carry theft coverage on the mechanical seamer, because it walks off a trailer faster than you would think.

How do alabama county business licenses layer on top?

Alabama is a strong home-rule state for occupational taxes. Every incorporated municipality and every county can issue a business license. The process is not centralized. In Mobile County, the License Commissioner's office issues a countywide license for unincorporated areas and the City of Mobile issues its own. You need both if you work inside the city limits. The county license is revenue-based, with minimum fees typically $75 to $150 a year. The city license is structured the same way but often requires a zoning review first. In the City of Madison, near Huntsville, the Revenue Department will not issue the license until you pass a zoning occupancy check, even for a contractor running from a home office, because the city wants to confirm no materials yard is operating illegally in a residential district.

Here is the order of operations for a new business. Apply for the state Residential Roofer license first and wait for the number. Register the LLC with the Alabama Secretary of State ($200 filing fee, plus a $100 probate-judge recording fee for a certified copy). Take the filed LLC certificate and the state license to each county and city revenue office. Some north Alabama offices process a license in 20 minutes if you walk in with the right documents and a check. Baldwin County takes 5 to 10 business days because they mail the license. That staggered timeline means you often cannot book a Baldwin County job for at least three weeks after filing.

What continuing education does alabama enforce for roofers?

The Alabama Home Builders Licensure Board requires six hours of approved continuing education per two-year renewal cycle. The six hours must include one hour on the Alabama Energy Code and one hour on Alabama law of contracts and liens, per board rule ^[9]. The remaining four hours can be general building science, safety, or business practices. The board keeps a list of approved online and in-person providers. The Alabama Roofing Association runs an approved six-hour renewal class twice a year at its annual conference and at regional workshops. Cost is $150 to $250 for non-members. You upload the completion certificates to the board's online portal no later than 30 days before the license expires.

Miss the CE deadline and your license drops into an expired status that blocks new contracts. Reinstatement takes a $150 late fee plus proof you completed the missing hours. A common trap: a contractor takes a Florida CE course approved by the Florida DBPR and assumes Alabama accepts it by reciprocity. It does not. The provider must hold specific Alabama approval. Verify the provider is on the board's current approved list before you pay. Call the board if you have any doubt.

How does the coastal building code affect a standing-seam roof cost in alabama?

In the Alabama Coastal High Hazard Area, which covers Baldwin County's Fort Morgan peninsula, Gulf Shores, Orange Beach, and Mobile County's Dauphin Island, the 2015 IRC with Alabama amendments requires metal roof systems tested to ASTM E1592 or TAS 125 for wind uplift ^[5]. This is not a suggestion. The building department checks the manufacturer's evaluation report during plan review and refuses the permit without it. A standard snap-lock panel that works fine in Montgomery gets rejected in Orange Beach if the report shows a 90 mph allowable wind speed and the site design speed is 130 mph, 3-second gust.

The cost penalty for a code-compliant coastal panel lives in the engineering and the clip spacing. Mechanical-seam panels with a factory-sealed seam and a direct-deck attachment tested to a high uplift capacity add $2.50 to $3.50 per square foot over a standard snap-lock that is fine inland. The clip count doubles or triples too. On a 3,000-square-foot Gulf Shores house, the extra clip cost alone can run $1,200 to $1,800. Add a Miami-Dade NOA or Florida Product Approval document cost of $300 to $600 if the manufacturer charges for it. Some post the docs free. McElroy Metal and Englert both keep current Alabama coastal evaluation reports online.

One specific callout: the 2015 IRC Section R908.2 limits reroofing to two layers of roof covering, and that does not bind metal roofs because you only have one layer. The coastal supplement, though, added inspection points for underlayment seam sealing. You tape all underlayment side and end laps with a 4-inch-wide self-adhered flashing tape approved by the underlayment manufacturer. The tape alone runs $260 to $400 for a 30-square roof. The inspector climbs onto the roof with a seam probe and checks six random lap points. Fail one and you re-tape the entire field and reinspect for $150.

Can a homeowner install their own standing-seam roof in alabama?

Yes, under a narrow exemption. Ala. Code § 34-14A-6 exempts an owner of property who personally performs construction, alteration, improvement, or repair on property used exclusively as that owner's residence ^[1]. "Personally performs" is the tripwire. You can install the roof yourself. Your brother-in-law can help for free. The moment you pay him cash or trade labor, you are acting as a contractor and must be licensed. The board has issued penalties against homeowners who hired unlicensed laborers on an owner-builder project.

You still pull a building permit. Most Alabama building departments require a signed, notarized Owner-Builder Affidavit stating you will occupy the house as your primary residence for at least 12 months after completion. The City of Hoover's form adds a line requiring you to list any assistance you receive and the compensation arrangement. You also waive certain insurance coverages. Your standard homeowners policy may not cover injuries to a friend helping you on the roof. Read the exclusions.

Alabama material suppliers sell steel panels directly to a homeowner. You pay full retail list, typically 18% to 25% higher than a contractor's trade price. On an $8,000 material package, that premium is roughly $1,600 to $2,000. You also forfeit the manufacturer warranty that requires a factory-trained installer. Some manufacturers like Drexel Metals will issue a materials-only warranty to a homeowner, but the fine print limits coverage to paint defects and perforation. The weathertightness warranty is void.

What is the bond or recovery-fund requirement for an alabama roofer license?

The Alabama Home Builders Licensure Board requires a residential roofer bond sized to annual gross revenue. Under the 2024 rulemaking, a contractor with up to $500,000 in gross annual revenue posts a $15,000 bond. Revenue between $500,001 and $1,000,000 requires a $25,000 bond. Revenue above $1,000,000 requires a $50,000 bond ^[3]. The bond must be a surety bond executed by a corporate surety licensed in Alabama, on a form the board prescribes. The board holds it as a consumer protection instrument. A homeowner can claim against it for an unpaid judgment tied to a defective roof.

A new contractor has a fast alternative: pay into the Alabama Home Builders Recovery Fund instead. The initial assessment is $150, paid once. This is not a bond. It is a pool funded by licensees that the board can tap to satisfy a judgment against a licensee with insufficient assets. The board caps any single recovery at $25,000 and caps aggregate recoveries from the fund at $100,000 per licensee. Choose the recovery fund and you still meet every other licensing requirement and keep continuous good standing. The bond and the recovery fund are alternatives. You cannot opt out of both. You pick one.

The practical cost of a $15,000 surety bond for a new roofer with a personal credit score above 680 is $150 to $300 a year in premium. The underwriter cares more about your personal credit and any past collections than about your roofing experience. I have seen an applicant with a 620 FICO quoted $900 for the same $15,000 bond. The recovery fund route skips that premium entirely, so it is the better opening move for a startup with marginal credit.

What regional cost differences exist inside alabama?

The price spreads are narrower than people expect. Material cost at the distributor counter in Huntsville, Birmingham, Montgomery, and Mobile is nearly identical, because the major steel service centers supply all four markets off the same coil price. The real difference shows up in the skilled-labor rate. A composite crew rate (lead mechanic per hour plus helper) for standing-seam in the Birmingham-Hoover metro is $120 to $150 an hour. In the Wiregrass region around Dothan, the same class crew costs $90 to $115 an hour. Spread that gap across 140 man-hours for a full tear-off and install and the labor delta is $2,100 to $4,900.

Dump fees are a second hidden difference. The City of Huntsville landfill charges a flat $35 per ton for construction debris with a $20 minimum. The City of Mobile charges $42 per ton. Jefferson County's landfill is $48 per ton. On a 4-ton tear-off of a single-layer asphalt roof, the disposal cost difference is $40 to $52. That is noise. But a contractor who prices the wrong landfill for the county can lose $150 on a job.

Third, the coastal market has a far tighter labor supply and longer permit waits. In summer, a Baldwin County residential reroof permit often sits in the queue 3 to 4 weeks before plan review clears. In a slower market like Cullman County, a same-week permit issue is routine if you hand-carry the application. That administrative delay forces the contractor to carry the materials receivable longer and shapes cash-flow pricing.

Frequently asked questions

Is a standing-seam roof worth the extra cost in alabama's climate?

For most homes, yes. A cool-metal roof cuts attic heat gain by 30 to 40 degrees in an Alabama July, which drops peak cooling demand. Energy Alabama cites modeled savings of 7% to 15% on summer electric bills for homes that switch from dark asphalt shingles to a high-SRI standing-seam panel. Dent resistance matters too during the March-to-May hail window in north Alabama. An impact-rated Class 4 steel panel takes 2-inch hail without perforation, where an asphalt shingle loses granules and needs replacement.

How does standing-seam compare to asphalt shingle cost in alabama?

An architectural asphalt shingle roof in Alabama costs $4.50 to $5.50 per square foot installed, tear-off included. Standing-seam is $9.50 to $14.00. That is roughly a 2.5x premium. The metal roof lasts two to three times longer (40 to 60 years for Kynar-finished steel versus 18 to 25 years for asphalt in Alabama heat). Stay in the house 20 years and metal wins on net present cost. Plan to sell in five years and the premium is hard to recover, except in upscale Birmingham suburbs.

Do I need a structural engineer for a standing-seam roof in alabama?

Only if you are changing the roof structure, adding a dormer, or the truss system is sagging. Most standing-seam retrofits over asphalt do not need an engineer because the metal panel is a lighter load. Asphalt shingles weigh 2.3 to 3.2 pounds per square foot. 24-gauge steel panels weigh 1.2 to 1.5 pounds per square foot. The building department may still ask for a truss load letter if the existing roof had two layers of shingles and you add strapping.

What permits does a standing-seam reroof require in alabama?

At minimum, a residential building permit from the city or county building department where the property sits. The application requires the contractor's state license number, proof of insurance, a description of the roof covering, the valuation of the work, and a wind-uplift report if the site is in the coastal high hazard zone. Some Alabama jurisdictions also require a right-of-way permit if you place a dumpster on the street.

Can I finance a standing-seam roof in alabama?

Yes. Several Alabama credit unions, including Redstone Federal Credit Union and Avadian Credit Union, offer a home improvement loan secured by the roof. Rates in early 2026 ran 7.5% to 10.5% for a 10-year term. Some standing-seam manufacturers partner with GreenSky or Service Finance for point-of-sale contractor-branded financing. The APR on those programs typically tops 12% for a 60-month term, so a credit-union HELOC is usually the cheaper path.

Does the alabama license require a trade exam for standing-seam?

Yes. The Residential Roofer license requires passing two PSI exams: a Business Management and Law for Residential Roofers exam (50 questions, 2-hour limit) and a Roofing Trade exam (60 questions, 2.5-hour limit). The trade exam covers roof deck prep, underlayment, metal panel installation, flashing, and safety. The PSI handbook lists the reference materials, which include the IRC, the Alabama Code, and the NRCA Roofing Manual.

How do I handle sales tax on a standing-seam roof in alabama?

The safest method is to work it out with a construction-focused CPA. In a lump-sum contract, the contractor is the consumer of the materials and remits sales tax to the supplier at purchase, then builds the tax-in cost into the contract price. In an itemized contract that splits labor and materials, the owner is the consumer and the contractor collects and remits sales tax on materials to the Alabama Department of Revenue. Misclassifying the contract structure has triggered audit assessments.

Is a standing-seam roof louder in alabama thunderstorms?

Not on a properly installed assembly. A standing-seam roof over solid decking (plywood or OSB) and a synthetic underlayment has essentially the same interior noise level as asphalt shingles. The tin-roof noise myth comes from exposed-fastener ag panels over open purlins on pole barns. Oak Ridge National Laboratory measured a 1 to 2 decibel difference between asphalt and metal over solid decking in simulated heavy rain ^[10].

What wind speed can a standing-seam roof handle in alabama?

Fully rated mechanical-seam assemblies tested to ASTM E1592 hold up to a 150 mph design wind speed when the clip spacing matches the tested uplift report. That exceeds the 140 mph 3-second gust design speed required for coastal Alabama under the 2015 IRC wind map. The key is the engineering letter, not the panel gauge. A 24-gauge panel with too few clips fails at a lower wind speed than a 26-gauge panel with a proper clip count.

Who handles contractor complaints for standing-seam roof problems in alabama?

The Alabama Home Builders Licensure Board investigates complaints against licensed residential roofers. You file a written complaint on the board's form, include a copy of the contract and any photographs, and mail it to the board office in Montgomery. The board can issue a citation, impose a fine up to $5,000 per violation, suspend or revoke the license, and direct a recovery-fund or bond payout for an unpaid judgment.

Is a metal roof tax credit available in alabama?

No state-level tax credit exists for metal roofing in Alabama. A federal ENERGY STAR tax credit of up to $500 for a cool-metal roof meeting the prescriptive requirements was available for installations completed before December 31, 2023. A federal rebate program under the HOMES Act is under development, but as of early 2026 it is not funded at the consumer-accessible level in Alabama. Check the Alabama Department of Economic and Community Affairs website for updates.

What roofing underlayment is required for standing-seam in alabama?

The 2015 IRC Section R905.10.2, adopted by Alabama, requires at least one layer of No. 30 asphalt-saturated felt or an approved synthetic underlayment for all metal roof shingles and panels. Most standing-seam manufacturers require a high-temperature synthetic rated to 240°F for steep-slope work. If the roof has cold-side condensation risk (common in north Alabama winter), the manufacturer may call for a vapor-permeable underlayment rather than a self-adhered impermeable membrane.
