In-depth: city-grade roof replacement for O'Fallon, IL
In O'Fallon, IL, 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.
Underlayment matters: synthetic base layers plus ice-and-water shields at eaves, valleys, and penetrations create redundancy against driven rain.
Ventilation is calculated, not guessed: we balance intake and exhaust, add baffled vents, and protect insulation so attics stay cooler and shingles live longer.
Fastening is county-aware: ring-shank nails, six-nail patterns in wind zones, and sealed starter strips that block uplift at perimeters.
Fresh metal flashings and sealed boots stop the leaks that old roofs hide.
We upgrade skylight perimeters with self-adhered membranes and diverters to manage flow.
Chimney bases get metal saddles and sealed reglets to prevent wicking and staining.
Penetrations are sealed with high-temp boots and mastic where needed, then inspected before cover layers go down.
We replace weak decking, secure it properly, and ensure planes stay true for crisp shingle lines.
Edges matter: drip edges are hemmed, gutters protected, and fascia interfaces sealed to stop wind-driven rain from sneaking behind the system.
Tie-ins are reinforced so flat-to-pitch transitions stay tight through storms.
