5 Roofing Myths Prairieville Homeowners Need to Stop Believing

Bad information about roofing is everywhere — from well-meaning neighbors to contractors who benefit from homeowners staying in the dark. Here are the five most common roofing myths in Ascension Parish and the truth behind each one.

Myth 1: “If It's Not Leaking, My Roof Is Fine”

By the time water is visibly entering your home, the damage is already significant. Water follows the path of least resistance and can travel several feet between decking and ceiling before showing as a stain or drip. What you cannot see: granule loss, cracked flashing, failed pipe boots, and early-stage decking rot. These are invisible until the damage cascades. Professional inspection every two years catches these issues at repair cost instead of remediation cost.

Myth 2: “New Shingles Over Old Ones Saves Money”

Layering new shingles over existing ones means the crew never sees what is underneath — rotted decking, failed underlayment, and compromised flashing stay hidden and continue degrading. The added weight stresses roof framing in a region already managing hurricane loads. Most manufacturer warranties require a clean deck installation, meaning an overlay voids the warranty on materials you paid full price for. A full tear-off costs more upfront and delivers a roof that actually lasts as long as it should.

Myth 3: “All Shingles Are Basically the Same”

Wind rating is the most critical spec for Prairieville homeowners. Basic three-tab shingles carry 60–70 mph ratings. Architectural shingles run 110–130 mph. Impact-resistant Class 4 shingles handle sustained hurricane-adjacent winds and hail that would destroy standard materials. In Ascension Parish — which sees tropical systems, severe thunderstorms, and hail — material choice is not cosmetic. Beyond wind rating, granule adhesion, algae resistance, and heat reflectivity all vary meaningfully by product. A shingle that develops algae streaks and retains excessive heat after two Louisiana summers was never a good value regardless of purchase price.

Myth 4: “I Don't Need to Document My Roof Until Something Goes Wrong”

Insurance adjusters work from documentation. Homeowners with a documented history of their roof's pre-storm condition are in a significantly stronger position during a claim. A before-and-after comparison makes the adjuster's job straightforward — and faster claim resolution means a better outcome for you. Photograph your roof from ground level on all four sides and from the attic. Store in cloud storage. Update annually before storm season. The 15 minutes spent today is worth hours of back-and-forth with an adjuster after the next storm.

Myth 5: “Any Contractor Can Work on My Roof”

Louisiana requires roofing contractors to hold a valid state contractor's license. Unlicensed contractors operate without liability insurance, without bonding, and without accountability if the work fails. If an unlicensed worker is injured on your property, you may be personally liable. Verify licenses through the Louisiana State Licensing Board for Contractors (lslbc.louisiana.gov) before signing anything. Ask for proof of liability insurance and workers' compensation. Any reputable contractor provides both without hesitation.

Frequently Asked Questions

How often should I have my roof inspected? Every two years as a baseline, and after any storm producing hail or sustained winds above 50 mph. Ascension Parish typically sees several such events per year.

Is an overlay ever a good idea? Rarely. It makes sense only when the existing single layer is in genuinely good condition, the decking is sound, and the homeowner understands the warranty implications.

Can an unlicensed contractor void my insurance? Potentially. Some policies require licensed contractors for covered repairs. Work done by an unlicensed contractor may be excluded from coverage on subsequent related claims.
