Residential Roofing in San Ramon
Most of our San Ramon work is residential. The housing stock here ranges from 1970s single-story ranches near downtown to 2000s two-story homes in Dougherty Valley, and each type has its own roofing considerations. Homeowners call us for replacement when a roof hits end of life, for leak repair after storms, and for inspections before buying or selling. We match shingle color and profile to existing roofs for repairs, and we handle HOA architectural approval on replacements where it applies.
- Full shingle roof replacement — We tear off the old roof to the deck, replace any rotted sheathing, install synthetic underlayment, and put down a new GAF or Owens Corning Duration shingle system with ridge vents. Most San Ramon shingle replacements run $14,000 to $28,000 and take two to four days. We pull the permit and handle the final inspection.
- Tile roof underlayment replacement — Many San Ramon tile roofs have sound tiles but failed underlayment. We lift the tiles, replace the underlayment, and reset the original tiles where they are sound. This costs 40 to 60 percent less than a full tile replacement and solves the leak. Most jobs run $9,000 to $18,000 and take three to five days.
- Roof leak repair and flashing rebuild — Leaks in San Ramon almost always trace to flashing at chimneys, skylights, or valleys, not the shingle field. We rebuild the flashing with new step and counter-flashing rather than smearing sealant over the gap. Most repairs run $350 to $900 and are completed same-day.
- Annual roof maintenance and gutter cleaning — We clear gutters and valleys, reseal pipe boots and flashing, and replace cracked sealant before it fails. San Ramon's fall leaf drop and summer heat make annual maintenance the cheapest way to extend roof life. Maintenance plans typically add three to five years to a shingle roof.
