In-depth: city-grade roof replacement for Ontario, California

In Ontario, California, 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.

We pair materials with threatsimpact shingles for hail, locked metal for wind, and tapered TPO for flats that pond.

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.

We exceed minimums with ring-shank nails, tight patterns, and sealed starters to lock shingles down.

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.

Chimney bases get metal saddles and sealed reglets to prevent wicking and staining.

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

We replace weak decking, secure it properly, and ensure planes stay true for crisp shingle lines.

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

Low-slope tie-ins receive special attention with granule-surfaced membranes or metal transitions that blend aesthetics with waterproofing.
