Solar Panels and Your Roof: What to Know First in St. Louis

Solar Panels and Your Roof: What to Know First in St. Louis
Quick answer: Replace an aging roof before adding solar so panels don't have to come off later; solar shingles integrate power into the roof itself.

For homeowners across the St. Louis metro, a roof isn't a generic product — it has to stand up to what St. Louis actually throws at it. Near the Gateway Arch, Forest Park, and the established suburbs of Clayton, Ladue, and Kirkwood, Trophy Exteriors builds and inspects every roof for local conditions, not a one-size-fits-all checklist.

What St. Louis weather really does to a roof

Roofs here contend with humid summers, cold winters, and dramatic freeze-thaw swings that lift shingles and form ice dams. St. Louis roofs face it all — spring hail and tornado-strength winds, summer derechos, and winter ice storms that form dams at the eaves and force water back under the shingles. That history is exactly why the biggest local threat — derecho winds, spring hail, and winter ice dams — shapes how we detail flashing, choose materials, and protect a St. Louis roof from the next event.

When it's time to replace your roof

Most asphalt roofs last 20-25 years, but widespread curling, bald spots, granules filling the gutters, and daylight in the attic all signal the end is near. A roof past its lifespan is a leak waiting to happen, and replacing it on your schedule beats replacing it after the ceiling falls.

The decking under your shingles

The plywood or OSB decking is the foundation the entire roof relies on, and soft or rotted sections must be replaced during a tear-off. Skipping bad decking to save money guarantees the new roof will fail early over those spots.

Energy-efficient and cool roofing

Cool-roof shingles and reflective coatings bounce sunlight instead of absorbing it, lowering attic temperatures and cooling costs in sun-baked climates. The savings are real over a roof's lifetime, especially where summers are long and hot.

Solar shingles and roof-integrated solar

Solar shingles blend energy production into the roof surface itself, an appealing option when you're replacing the roof anyway. They cost more than panels but preserve the look of the roofline for homeowners who prioritize appearance.

How a new roof affects home value

A new roof is one of the highest-return exterior projects at resale, and buyers routinely walk away from homes with visibly aging roofs. Beyond resale, a sound roof protects everything beneath it, so the real return shows up as avoided water damage.

Permits, code, and insurance in St. Louis

St. Louis City and County municipalities require reroof permits, and the region's freeze-thaw swings make ice-and-water shield at the eaves a smart, sometimes required, upgrade. With hail, wind, and ice all in the mix, St. Louis homeowners should document storm damage quickly and make sure eave and valley protection is done right.

Frequently Asked Questions

Can I put solar on my roof?

Yes, either as panels mounted on a sound roof or as integrated solar shingles during a replacement. It's best to replace an aging roof before adding solar so you're not removing panels later.

What are the signs I need a new roof?

Curling or missing shingles, granules in the gutters, dark worn patches, a sagging roofline, and daylight or stains in the attic are the classic warning signs. Several of these together usually mean replacement.

Does a new roof add home value?

Yes. A new roof is one of the highest-return exterior upgrades at resale and removes a common buyer objection. It also protects everything under it from water damage.
