Roofing in San Marino.
Roofing in San Marino means careful work on established, character-rich homes — many with original clay or concrete tile, mature trees overhead, and standards a roof has to live up to.
What San Marino roofs are up against.
San Marino is a small, heavily-treed city of established homes, and that shapes its roofs. Towering oaks and deodars shade the streets and drop heavy debris into valleys and gutters; shaded north slopes stay damp and grow moss, while the dry San Gabriel Valley summers still bake the exposed slopes. A great many homes wear original clay or concrete tile — tile that lasts for generations while the underlayment beneath it quietly fails. Homeowners here care about how the roof looks: they want repairs and re-roofs that keep the period character, with matching tile and low, quiet detailing rather than something that fights the architecture. The work is slower and more careful by nature, which is exactly what these homes need.
What we work on in San Marino.
- Clay and concrete tile on the traditional and Spanish-style homes
- Slate and composition on some larger homes
- Flat and low-slope over additions and rear wings
The repairs San Marino homeowners call us about.
- Cracked and slipped tile over underlayment that has failed
- Moss and trapped debris in shaded valleys under mature trees
- Leaks at old chimney, dormer, and sidewall flashing
- Matching original or discontinued tile profiles
What a San Marino roof job looks like with us.
On a San Marino tile roof we usually do a lift-and-relay: carefully remove and store the original tile, replace the worn underlayment and flashing, and re-lay the same tile so the house looks untouched. The flashing rebuilds on these older homes take patience to get right. Every job is documented from the air.
We're a family-owned, licensed C-39 contractor (CSLB #1137536), Owens Corning Preferred and Polyglass certified, owner-run by a roofer with nearly a decade of hands-on Los Angeles experience. Our work is backed by a 10-year workmanship warranty and a perfect 5.0 rating across 113 verified reviews.
Common questions from San Marino homeowners.
My San Marino tile roof leaks but the tile looks fine — why?
Because the tile outlives the underlayment beneath it. The felt that actually keeps water out dries and cracks in 20 to 30 years while the tile is still good. We lift and save your tile, replace the underlayment and flashing, and re-lay it — a watertight roof with the look unchanged.
Can you match the tile on my older home?
Usually, yes. A lift-and-relay reuses your existing tile, so the profile and color stay original. When added tile is needed, we source the closest match and place it where it is least visible.
Do you do careful work on established and historic homes?
Yes — much of our San Marino work is on traditional and period homes. We work to preserve the look and detailing of the house, not replace it with something generic.

Roofing codes & requirements in San Marino
Energy / cool roof (Title 24)
San Marino sits in California Energy Commission Climate Zone 9. Under Title 24, Part 6, a low-slope or flat roof here must use a cool-roof product (aged solar reflectance of at least 0.63 and thermal emittance of at least 0.75 — roughly SRI 75) when you replace 50% or more of the roof or about 1,000 sq ft or more. Steep-slope (pitched) residential roofs in Climate Zone 9 are exempt from the cool-roof requirement, so standard shingle or tile is fine. Small like-for-like repairs generally don't trigger it. See the California Energy Commission standards and the CRRC directory for rated products.
Fire
San Marino is flat and isn't in a Very High Fire Hazard Severity Zone, so a standard Class A roof is typical. Confirm your specific parcel. You can check any parcel on the CAL FIRE hazard-zone viewer.
Decking / sheathing
Many older San Marino homes were built with spaced 1×6 “skip” sheathing under the original roof. For a modern shingle or tile system — and for a Class A assembly — that decking often has to be overlaid with solid sheathing, and any rotted boards replaced. We confirm exactly what your roof needs with a deck inspection at tear-off, not a guess.
Color & materials
Roof color isn't regulated by code. Where a cool roof is required you need a CRRC-rated product that meets the SRI — and those come in a wide range of colors, not just white.

Common San Marino roofing-code questions
Does my San Marino roof need to be Title 24 cool-roof compliant?
Only on flat or low-slope sections. San Marino is in Climate Zone 9, so Title 24 requires a cool roof (about SRI 75) when you replace 50%+ of a low-slope roof, but steep-slope shingle and tile roofs are exempt here.
Is San Marino in a fire zone that requires a Class A roof?
Usually no — most of San Marino isn't in a Very High Fire Hazard Severity Zone, so a standard Class A roof is typical. Confirm your parcel on the CAL FIRE viewer.
Will my old spaced sheathing need to be re-decked?
Sometimes. Older San Marino homes often have spaced 1×6 sheathing; a modern shingle or tile system (and a Class A assembly) may need solid sheathing over it. A deck inspection at tear-off tells us for sure.
Financing available for qualified San Marino homeowners
You don't have to pay for a roof all at once: financing is available for qualified homeowners, subject to qualification — written itemized pricing first, financing second, never any pressure. And because Title 24 cool-roof products are qualifying energy improvements, a San Marino re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
