Why Cheaper Isn't Always Better When It Comes to Roofing

Every roofing company will tell you to avoid the cheapest bid. Coming from a contractor, that advice can sound self-serving. But in Louisiana specifically, "cheaper" now carries a very real, very specific risk that goes beyond workmanship — it can mean the roof over your head was never legally permitted, was never built to current code, and could stand between you and selling your home years down the road.

We've recently watched this play out on multiple jobs, and it's a pattern that's growing, not shrinking, as Louisiana's rules have tightened.

Louisiana's Roofing Rules Have Gotten Stricter, Fast

Three separate pieces of Louisiana regulation have stacked on top of each other in under three years, and it's easy to lose track of which one does what:

• 2021 IRC adoption (effective January 1, 2023) — Louisiana adopted the 2021 International Residential Code as its statewide baseline residential building code, including the current wind-resistance and roof assembly requirements discussed below.
• Act 239 (effective August 1, 2025) — Requires parishes and municipalities to issue a permit and perform inspections for all residential and commercial roof construction and reroofing projects, regardless of job size. Before this, permit enforcement on reroofs varied widely from parish to parish, and plenty of reroofs happened with no permit at all.
• Act 422 (effective January 1, 2026) — Created a dedicated Residential Roofing license classification through the Louisiana State Licensing Board for Contractors (LSLBC). Contractors performing residential roofing work valued at $7,500 or more must hold this license (or an equivalent residential construction or commercial roofing license) and pass a trade exam if they don't already hold a related license. Skipping permits, misrepresenting a project's value to dodge the threshold, or skipping inspections can bring real disciplinary action from the LSLBC.

Put together, that's a code baseline, a permit mandate, and a licensing requirement all landing within about three years — and as of today, all three are fully in effect.

What Current Code Actually Requires in High-Wind Parishes

The 2021 IRC isn't just paperwork — it sets specific, technical requirements for how a roof has to be built in Louisiana's high-wind areas, including all of South Louisiana.

The 6-Nail Shingle Pattern

IRC Section R905.2.6 requires asphalt shingles to be fastened with six nails per shingle, instead of the standard four, in any area with a design wind speed of 110 mph or greater. All of South Louisiana falls into this category. A 4-nail pattern is faster and cheaper to install — it's also non-compliant in these wind zones, and it's one of the easiest corners for a rushed or inexperienced crew to cut, since it's invisible once the shingles are down.

Underlayment Requirements

Current code also specifies how underlayment has to be applied on steep-slope roofs, including double-layer application methods in many installations. Underlayment is the roof's last line of defense if wind or hail compromises the shingles above it — skimping here doesn't show up as a problem on day one, but it shows up the first time the roof is actually tested by a storm.

Both of these are baseline code requirements in qualifying wind zones — not upgrades, and not the same thing as voluntary programs like FORTIFIED Roof™ certification, which goes further still. For more on how FORTIFIED compares to a standard code-built roof, see our FORTIFIED vs. standard roof guide.

Contractors Are Still Skipping Permits and Licenses

Despite the rules tightening, we still regularly run into roofs where no permit was ever pulled, and crews operating without the license the work now legally requires. It's not hard to see why: skipping the permit avoids inspection scrutiny and fees, and an unlicensed crew has lower overhead than one carrying the insurance and licensing costs that come with doing it correctly. Both let a contractor underbid a legitimate, licensed, permitted competitor — and the homeowner often has no way to tell the difference from the bid alone.

The Home Sale Problem: No Permit, No Closing

This is the part that catches homeowners off guard, and it's a pattern we've now seen across multiple transactions, not an isolated incident.

When a home goes under contract, a title company or the buyer's inspection process will often turn up whether a permit exists for the current roof. If the roof was replaced without one, the burden shifts entirely to the seller — the homeowner, not the contractor who did the original work — to prove after the fact that the roof was actually built to code.

In practice, that means bringing in a licensed contractor to pull an after-the-fact permit, which at minimum requires removing a section of shingles — in our experience, at least 100 square feet — to expose and inspect the decking, underlayment, and fastening pattern underneath. If that inspection shows the roof was built correctly, the permit can be issued and the sale moves forward. If it wasn't, a full re-roof is often required to bring the roof up to current code before the home can close — not a patch, not a partial fix, but a complete replacement, on a timeline dictated by a pending sale rather than the homeowner's own planning.

That's an expensive, stressful position to be in, and it traces directly back to a roofing decision made years earlier — often one driven by picking the cheapest bid without asking why it was cheap.

Why the Cheapest Bid Often Costs More in the End

A lower price isn't automatically a warning sign — but it's worth understanding exactly where the savings are coming from. In our experience, an unusually low bid is usually cutting one or more of the following:

• No permit pulled — saves the contractor time and fees, but leaves the homeowner with no official record the work meets code.
• No license, or the wrong one — lower overhead for the contractor, but no LSLBC accountability if something goes wrong.
• Wrong nailing pattern — faster labor, but non-compliant and far more vulnerable to wind uplift in a storm.
• Inadequate underlayment — cheaper materials and less labor, but a compromised backup layer exactly when it matters most.

Any one of these can turn into an insurance claim denial after storm damage, a manufacturer warranty that was never actually valid, or the forced-reroof-at-resale scenario above. In nearly every case we've seen, the total cost of the cheap roof plus the eventual fix is higher than simply paying for a permitted, licensed, code-compliant installation the first time.

How to Vet a Roofing Bid Before You Sign

• Verify the license. Look up the contractor directly through the Louisiana State Licensing Board for Contractors before signing anything.
• Confirm they're pulling a permit. Ask to see the permit application or number once it's filed — a legitimate contractor will have no issue providing this.
• Ask about your wind zone. A contractor who can't tell you whether your home requires a 6-nail pattern or specific underlayment likely isn't accounting for it.
• Get it in writing. Scope, materials, nailing pattern, and permit responsibility should all be spelled out in the contract, not left verbal.
• Ask why a bid is low. A significant gap between bids usually has a specific, identifiable reason — ask what it is before assuming it's just a better deal.
