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

Weather in Ontario, California shifts fast, so we document the roof deck, flashing failures, and leak paths before we write your scope, preventing change-order surprises.

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

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.

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