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.
