Questions to Ask Before Signing an Aluminum Patio Cover Contract
Ten specific details decide whether your patio cover lasts 25 years or 5. Most homeowners sign without asking about any of them.
The contractor offers a price. You agree. The installation happens. The cover looks fine at year 1. By year 5, the panels are chalking, the flashing's leaking behind your wall, and the drainage is pouring a sheet of water onto your patio because the connection to your gutters was not addressed.
That sequence isn't accidental. It's the predictable outcome of signing a contract that doesn't specify the installation spec in writing. The contractor commits to the price. They don't commit to the aluminum gauge, attachment method, drainage routing, engineering rating, or coating warranty unless you ask before signing.
Ten questions. Every answer in writing. Done before the deposit clears.
The Questions, At a Glance
12 questions before you sign.
A patio cover contract that doesn't answer these questions is incomplete. Every "yes, of course" you accept verbally is something a defending contractor can deny six months later. Get them in writing.
Twelve Questions Each one should yield a written answer in the contract

⚠ Red flag combos
Cash-only · door-to-door pitch · "today only" pricing · no physical address · permits "you can pull" · over 25% deposit · no written warranty. Any two of these = walk away.
Joe's hands you these answers in writing — before you sign.
The 10 questions cover what gets installed (panel specs, attachment, drainage), how it gets installed (engineering, permits, timeline), and what happens after (warranties, hurricane repairs, landscape protection). Each question has a right-answer parameter and a red flag.
| # | Question | Right Answer Looks Like | Red Flag |
|---|---|---|---|
| 1 | What aluminum gauge are the panels? | .032" minimum residential, heavier for hurricane zones | Contractor doesn't know or won't write it down |
| 2 | How is it attached to your home? | Ledger board with full flashing detail, OR free-standing on independent footings | Vague answer or we figure it out on site |
| 3 | What's the wind load engineering rating? | ASCE 7 / LSUCC compliant, 130-150 mph design wind speed for your parish | No engineering documentation |
| 4 | How does drainage tie into your existing gutter system? | Specific tie-in detail or dedicated outlet documented | We'll figure out drainage on site |
| 5 | Who pulls the permit? | Contractor pulls permit; parish permit number to homeowner | Contractor avoids permit discussion |
| 6 | What's the panel coating warranty? | AAMA 2604/2605 fluoropolymer, 25-40 year color/chalk warranty | AAMA 2603 polyester, 5-10 year warranty |
| 7 | What's the structural warranty? | Lifetime on aluminum frame (premium installations) | Less than 10 years on frame |
| 8 | What happens if a hurricane damages the cover? | Repair vs replacement criteria documented | "We'll deal with it if it happens" |
| 9 | What's the timeline from signing to completion? | 2-5 weeks contract-to-use including permit pull | "Soon" or "as quickly as we can" |
| 10 | What happens to your landscape during installation? | Crew access plan, equipment placement, debris management documented | "We'll be careful" |
Question 1: What Aluminum Gauge Are the Panels?
Heavier-gauge aluminum on the roof panels resists wind uplift better. A standard residential installation uses a minimum panel thickness of .032 inch. Premium configurations for hurricane zones use heavier panels.
The gauge difference matters when storms push wind under the panel edges. Lighter panels deform; heavier panels hold their shape. Your patio cover after a Cat 2 hurricane: heavier-gauge panels tend to stay attached, lighter panels get pulled off and become projectiles.
Ask for the gauge in writing. The contractor who can't tell you is using whatever the supplier delivers, which often isn't the gauge they implied at the sales conversation.
Question 2: How Is It Attached to Your Home?
Two valid attachment methods: A ledger board attached to your home, or free-standing on independent footings.
Ledger board attachment ties the patio cover to your home's structural wall. Done correctly, it's solid and integrated. Done wrong, it creates a path for water to track behind your siding into the wall cavity. The flashing detail is critical — proper flashing extends the home's water-management system over the ledger board so water that hits the patio cover roof flows away from the home rather than behind the wall.
Free-standing posts on independent concrete footings don't attach to your home at all. The cover sits on its own foundation. Drainage and weather protection still need to be designed, but the failure modes are different — no risk of water tracking behind your siding.
Ask your contractor which method they're using, and request the flashing detail in writing if it's a ledger board attachment. The contractor who waves off the flashing question is the one whose installations leak in years 4-5.
Question 3: What's the Wind Load Engineering Rating?
The Louisiana State Uniform Construction Code (LSUCC) sets wind load requirements for attached structures in coastal Louisiana — Risk Category II, 130-150 mph design wind speed depending on your parish. ASCE 7 is the underlying engineering standard.
Engineering-stamped drawings are required for the parish permit on most patio cover installations in Greater New Orleans. The drawings document the post sizes, footing depths, beam spans, panel attachment, and connection details—the engineering math that ensures the structure withstands the design wind load.
Ask to see the engineering documentation. The legitimate installer has it from the panel manufacturer or from a structural engineer they use. The illegitimate installer either doesn't have it or doesn't know what you're asking about.
TIP:
Engineering documentation is normal for any permitted patio cover installation in Louisiana. If your contractor hesitates on this question, the installation probably isn't getting permitted — which means it's also not getting inspected — and problems show up later when you can't get insurance to cover the structure.
Question 4: How Does Drainage Tie Into Your Existing Gutter System?
Patio cover roofs collect rainwater. Where that water goes is a design decision, not a happy accident.
Two reasonable answers: Tie the patio cover drainage into your home's existing gutter system at a specific point, OR install a dedicated outlet that routes water away from your foundation independently. Both work; both should be documented in your contract.
The wrong answer: "We'll figure out drainage on site." That's the answer where the contractor's crew comes out, realizes the drainage doesn't fit cleanly into the existing system, and either dumps the water at the cover edge (a sheet of water across your patio every rain) or routes it to the foundation (slow water damage to the slab edge).
Request the drainage details in writing. The sketch on the contract is fine — what matters is that drainage routing is part of the contract.
Question 5: Who Pulls the Permit?
Aluminum patio covers attached to your home generally require a parish building permit in Jefferson Parish, Orleans Parish, and most Greater New Orleans parishes. The contractor's job is to pull it.
When the contractor pulls the permit, your installation gets inspected. The inspector verifies engineering compliance, attachment detail, electrical (if applicable), and code compliance. The inspection protects your installation — and protects you under your homeowners insurance, which can deny claims on unpermitted structures.
Ask: "Will you pull the permit, and what's the parish permit number going to be?" The legitimate contractor pulls permits routinely. The illegitimate one tries to talk you out of permits to save time and the inspection.
TIP:
Verify the permit yourself after the contractor pulls it. Most parishes have an online permit lookup. Search by your address; the patio cover permit should appear, including the contractor's license number, project description, and inspection schedule. Permit verification is the homeowner's job.
Question 6: What's the Panel Coating Warranty?
The aluminum panels on your cover have a paint coating system. The coating decides how long the panels stay looking like new vs starting to chalk and fade.
AAMA 2604 or 2605 fluoropolymer (Kynar 500 or Hylar 5000) coatings carry 25-40 year color and chalk warranties. This is what premium installations use. Your panels stay color-stable for decades.
AAMA 2603 polyester coatings carry 5-10 year warranties. This is what budget installations use. Your panels start chalking visibly at year 3-5 in Louisiana sun exposure.
Ask: "What AAMA standard is the coating?" The right answer is "AAMA 2604" or "AAMA 2605." Anything else is a budget coating that won't last.

Question 7: What's the Structural Warranty?
Two warranties matter on your patio cover: the structural warranty on the aluminum frame and the workmanship warranty on the contractor's labor.
Premium installations include a lifetime warranty on the aluminum frame against material defects. Lower-tier installations carry 10-15-year structural warranties. The aluminum itself doesn't fail in either case under normal use; the warranty difference matters for material defects (anodizing problems, manufacturing defects in the aluminum).
Workmanship warranties cover the contractor's labor — typically 1-5 years on the installation itself. After that, installation issues are your responsibility.
Ask for both warranties in writing. The structural warranty is from the panel manufacturer; the workmanship warranty is from the contractor. Different paper, different coverage.
Question 8: What Happens if a Hurricane Damages the Cover?
Patio covers in Louisiana go through hurricanes. Some installations survive intact; some need repairs.
Ask your contractor: how do they handle hurricane damage? The reasonable answer involves repair vs replacement criteria. Panels can typically be re-attached or replaced individually if the frame is intact — the panels are the failure point in most hurricane scenarios. Frame damage usually means full replacement.
Hurricane damage repairs are typically covered under your homeowners insurance Coverage A (if attached to the home) or Coverage B (if free-standing). The contractor should be able to walk you through the documentation process and work with your insurance adjuster on the repair scope.
The contractor who says, "We'll deal with it if it happens" is the one whose installations disappear from your contact list after the storm. Ask before signing how the company handles post-hurricane repairs and what their typical response time is during storm season.
Question 9: What's the Timeline From Signing to Completion?
Reasonable timeline for a Greater New Orleans patio cover installation:
- Contract signing to permit pull: 1-2 weeks (permit submission and parish processing)
- Permit issuance to installation start: 1-2 weeks (scheduling, materials)
- Installation duration: 1-3 days for flat pan, 3-5 days for insulated panel
- Total: 2-5 weeks contract-to-use
The contractor who says "we can have you done by next weekend" is either skipping the permit or doesn't have any other work on the calendar. Both are red flags. The legitimate timeline includes the parish permit process — there's no way around it for permitted work.
Ask for the timeline in writing, including the expected start and completion dates. Delays happen (weather, supplier issues), but the timeline at signing should be realistic.
TIP:
Storm season timeline matters. Patio cover installations scheduled from June through November in Louisiana are at risk of weather delays. Your contractor's timeline should build in a buffer for storm delays during hurricane season. The contractor who promises a 2-week installation in August is either lucky with the weather or about to disappoint you.
Question 10: What Happens to Your Landscape During Installation?
Patio cover installations involve crew access, post-hole excavation, equipment placement, and debris management. Your existing landscape is in the way.
Ask before signing: where does the crew park, where does the equipment stage, what gets damaged during installation, and what gets restored after. The conscientious contractor walks the site with you before the contract is signed and identifies what gets impacted. The careless one shows up on the day of and parks the tracked excavator on your grass.
The landscape protection plan should be in writing. Doesn't have to be elaborate — even a sentence or two specifying "crew uses driveway access only, equipment stages on existing patio, post hole excavation creates spoil pile that contractor removes daily" prevents surprises and disagreements at year-end.
WARNING:
Verbal-only spec promises don't survive year 3. The contractor who said "I always use the heavier gauge" doesn't remember when the panels start chalking, and the manufacturer's warranty doesn't apply because the spec wasn't in writing. Get every spec answer in the written contract — gauge, attachment detail, drainage routing, engineering rating, coating standard, warranty terms, permit pull, timeline, and landscape protection. Verbal commitments don't carry into year 3.

Frequently Asked Questions
Should you get multiple bids before signing?
Yes — three bids are the standard recommendation for a patio cover project. The bids should be apples-to-apples on the 10 questions. Comparing a $4,000 bid that uses .024" panels and AAMA 2603 coating to a $7,000 bid that uses .032" panels and AAMA 2604 coating gives you a price differential that doesn't reflect equal installations. Bid comparison is only useful when the spec is held constant.
What if your contractor says they don't pull permits?
Red flag. Permitted patio cover work is the standard in Greater New Orleans for any structure attached to your home. A contractor who avoids permits is either not licensed to perform permitted work or is trying to skip the inspection. Either way, your installation is uninsurable — the homeowners' "ordinance and law" exclusion denies coverage for unpermitted structures.
Is engineering documentation included or extra?
Should be included. Engineering-stamped drawings are required for the permit; the contractor needs them to pull the permit. The cost is built into the installation price for legitimate installers. If a contractor charges extra for engineering, ask why — it's not normally a separate line item.
How much down payment is reasonable on signing?
Industry standard: 25-50% down at contract signing, balance on completion or by milestone (after permit pull, after installation start, after final inspection). 100% upfront is a major red flag — legitimate contractors don't need full payment before any work happens.
Can you make changes after signing?
Yes — change orders are standard practice. They should be documented in writing with the price impact. Changes during installation (you decide on a different panel color, you want to upsize the cover) get added to the contract via change order; the contractor doesn't just adjust the bill at the end without prior agreement.
What if your installation fails the permit inspection?
Contractor's responsibility to bring the installation to code. The whole point of the inspection is to catch issues before final payment. If the contractor refuses to fix inspection failures, your contract should give you the right to withhold final payment or hire another contractor to complete the work.
Is patio cover work tax-deductible?
Generally not as a current-year deduction. It's a capital improvement that adds to your home's basis and can reduce capital gains tax at sale. Consult a tax advisor for specifics — IRS treatment varies based on whether the structure is for personal residence or rental property.
