Roof Replacement Built for This City's Homes, Not a Generic Tract House
Full tear-off and replacement for the steep-pitched Victorian and Edwardian fronts and the flat rear sections San Francisco's rowhouse-style homes are actually built with — backed by manufacturer warranties.
When Replacement Makes More Sense Than Repair
We'll never push a full replacement when a repair genuinely solves the problem — but a few signs mean it's time to stop patching:
- Widespread wear — curling, cracking, or granule loss across most of the roof, not just one section.
- Repeated leaks in different spots — a sign the underlayment and deck have reached the end of their service life, not just one bad flashing detail.
- A failing flat membrane — seams opening, chronic ponding, or blistering on the low-slope rear section behind a Victorian's parapet.
- Original or second-generation roofing — common on pre-1940s San Francisco homes that have never had a proper tear-off.
What a Replacement Includes
- Full tear-off and deck inspection — repair any water-damaged plywood before new material goes down.
- Material selection matched to the roof section: shingle or metal for pitched fronts, TPO or modified bitumen for flat rear sections.
- Title 24 cool-roof compliance confirmed where it applies (statewide for flat/low-slope, exempt for steep-slope re-roofs in San Francisco's climate zone).
- Permitting, staging plan for your specific lot and street, and full cleanup.

Is a cheaper roofing quote ever the better deal?
Rarely, and it's worth being cautious. A quote well below others often means thinner materials, a crew that skips deck repair, or a contractor cutting corners on permits, disposal, or Title 24 cool-roof compliance for a flat section. Compare what's actually included — tear-off, deck inspection, underlayment, flashing, cleanup, warranty — not just the bottom-line number.
Does my roof need to comply with Title 24 cool-roof rules?
It depends on slope. California's Title 24 requires cool-roof-rated materials statewide for flat and low-slope re-roofing, but San Francisco's coastal climate zone is exempt from the cool-roof requirement for steep-slope residential re-roofing. We confirm what applies to your roof during the estimate.
How many quotes should I get before choosing a roofer?
Two to three written, itemized estimates is enough to spot outliers in either direction. More than that usually just adds scheduling friction without much new information.
Will a new roof affect my homeowners insurance?
Sometimes. Some carriers offer discounts for updated roofing materials or improved fire/wind ratings. Ask your insurance agent directly, since discount availability and amount vary by carrier and policy.
