How Do I Know If I Need a Full Replacement? in St. Louis

How Do I Know If I Need a Full Replacement? in St. Louis
Quick answer: Widespread curling, bald spots, granules filling the gutters, and attic daylight together point to replacement rather than another patch.

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.

Granule loss and what it means

The granules on asphalt shingles are their sunscreen, and when they wash into the gutters the shingle underneath ages fast. Heavy granule loss on a roof that's more than 15 years old usually means replacement is on the horizon.

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.

Repair or replace: how to decide

A few missing shingles or a single worn flashing is a repair; widespread damage, multiple leaks, or a roof near the end of its life points to replacement. An honest inspection tells you which side of that line you're on instead of guessing.

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

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.

Should I repair or replace my roof?

Isolated damage on an otherwise sound roof is a repair; widespread wear, multiple leaks, or an aging roof usually calls for replacement. A professional inspection gives you a straight answer instead of a guess.

How long should my roof last?

Asphalt shingles typically last 20-25 years, metal 40-70, and tile or slate 50-plus. Ventilation, installation quality, and local weather all move that number up or down.
