In-depth: city-grade roof replacement for O'Fallon, MO

In O'Fallon, MO, microclimates swing between salty air and inland heat. We start with a forensic inspectionphotographing decking, skylights, chimneys, and prior patchesso scope, pricing, and timelines stay clear.

Material choices are collaborative: Class 4 impact shingles for hail corridors, standing-seam metal where wind uplift dominates, and TPO/PVC membranes with tapered insulation to eliminate ponding.

Redundant defense comes from synthetic underlayment and peel-and-stick membranes at leak-prone zones.

Balanced airflow keeps heat from baking shingles; we size vents, block wind wash, and reduce HVAC load.

Fastening is county-aware: ring-shank nails, six-nail patterns in wind zones, and sealed starter strips that block uplift at perimeters.

Flashing is rebuilt newstep, counter, apron, and pipe bootsso water cannot sneak in around walls or penetrations.

Skylights get curbs, peel-and-stick, and crickets where needed so runoff clears cleanly and interior finishes stay safe.

Chimneys are reworked with reglet or counter-flashing, proper mortar, and saddle crickets to steer water away from brick and siding.

Every pipe, vent, and mast gets a fresh boot and sealant, photographed for your records.

Deck repairs are completed with like-kind sheathing, fastened tight, and verified level so shingles lay flat and look clean.

Hemmed drip edges and sealed transitions keep water moving into gutters, not behind them.

Tie-ins are reinforced so flat-to-pitch transitions stay tight through storms.

We stage sites with catch tarps, walk boards, and debris nets, keeping landscaping, pools, and driveways safe.
