We’ve been climbing San Marino roofs since 1984. We know the difference between a 1926 Spanish Colonial on Woodstock Road and a 1940 Tudor on Virginia Road, and we know that replacing either means matching what is already there - not slapping on whatever the supplier has in the warehouse. Our Roof Replacement & Installation crews are trained in historic tile restoration, not just tear-off and shingle. When you live in a city where the median home was built before 1950, that distinction matters.

Tile Roofing - San Marino’s Signature Need
Tile roofing is not a sideline for us in San Marino - it is the core of what we do here. The city’s residential fabric is almost entirely 1920s-1950s estate-scale homes in Spanish Colonial Revival, Mediterranean Revival, and Tudor styles, most topped with original clay tile roofs that are now 70-100 years old. The city’s powerful design culture and homeowner expectations mean nearly every re-roof must exactly replicate the existing clay tile profile, color, and ridge mortar detail. This makes San Marino a specialty tile-restoration and tile-matching market fundamentally different from the asphalt-shingle re-roof work that dominates neighboring Arcadia or Alhambra.
On a 1929 Mediterranean Revival estate near Lacy Park, we replaced a failing S-curve clay tile roof where original 30-lb felt had delaminated. We sourced matching salvaged tiles from a Pasadena demolition site, reinstalled them over new underlayment, and re-created the original mortar ridge detail to comply with city design standards. That is the level of specificity San Marino homes require.

Full Roof Replacement
A full roof replacement in San Marino is rarely a simple tear-off. The housing stock is almost exclusively large single-family estates built between roughly 1915 and 1955, with complex multi-plane rooflines and original S-curve or flat-profile clay tile that owners expect to preserve or replicate in-kind. Underlayment beneath these tiles is frequently original 30-lb felt that has long since failed, meaning a proper job requires full underlayment replacement while carefully storing and reinstalling or matching every existing tile. We do not shortcut this. The price we quote is the price you pay - no surprises when we open up the roof and find what we already expected to find.

Flat Roofing
Many San Marino estates include secondary flat roof sections over sunrooms, service wings, or garage structures added in the 1930s-1950s. These low-slope areas fail differently than the main clay tile roof - water ponds, flashings crack, and the original coal-tar or early modified bitumen degrades. We replace these with modern TPO or modified bitumen systems that integrate cleanly with the historic roofline above. Our crews understand how to transition from flat to pitched without creating the visual clash that would violate San Marino’s design sensibility.

Asphalt Shingles & Metal Roofing
While clay tile dominates San Marino’s historic core, we also install asphalt shingles and metal roofing where appropriate - typically on newer additions, detached structures, or homes where the original roof has already been altered. We are authorized installers of GAF, CertainTeed, and Owens Corning products, and we never substitute materials without your written approval. A square deal means the brand on the estimate is the brand on the roof.

Trusted Brands We Service in San Marino
We are authorized installers for seven leading manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For San Marino’s tile roofing needs, Boral’s clay tile lines and CertainTeed’s specialty profiles are often the closest modern matches, though we frequently supplement with salvaged tiles sourced from demolition sites across the San Gabriel Valley. We stock common underlayment, flashing, and fastening materials locally to minimize wait times, but we never rush a tile match. A roof that lasts 70 years deserves the two extra weeks to find the right clay. If we quote a brand, that is what gets installed - no bait-and-switch, no “equivalent” substitutions you did not agree to.
Common Roof Replacement & Installation Problems We See in San Marino Homes
- Original 30-lb felt underlayment has failed beneath intact clay tiles. The tiles look fine from the street, but water migrates through cracked felt during winter storms and leaks at valleys and penetrations. Full underlayment replacement is required, with every tile carefully removed, stored, and reinstalled - or matched from salvage if breakage occurs.
- Santa Ana winds dislodge mortar ridge caps and loosen individual tiles. Positioned at the base of the San Gabriel Mountains, San Marino sits in the path of amplified wind events that funnel through the valley. Steep multi-plane rooflines common on 1920s estates are especially vulnerable. We re-bed ridge caps with modern flexible mortars and install supplemental mechanical fasteners where code allows.
- Discontinued clay tile profiles cannot be matched from new stock. Because mid-century S-curve and flat-profile tiles are no longer manufactured, San Marino roofers routinely source salvage tiles from demolition sites elsewhere in the San Gabriel Valley. Homeowners often accept mismatched tiles or costly custom orders, but we prefer the salvage route for color and profile consistency that satisfies discerning, high-net-worth homeowners.
- Complex roof geometries overwhelm aging flashings. Century-old San Marino homes have multiple intersecting planes, dormers, and chimney penetrations. Original copper or galvanized flashings fatigue at bends and seams. We replace with matching material - copper where copper was, lead where lead was - to maintain both function and historical accuracy.

FAQs - Roof Replacement & Installation in San Marino
Yes - San Marino’s design standards and homeowner expectations virtually require exact replication of existing clay tile profiles, colors, and ridge mortar details. Most of these homes are designated historic or sit in areas where visual consistency is enforced through design review. We source matching tiles from salvage when new stock is unavailable, and we document every detail before removal to ensure the restored roof is indistinguishable from the original. Call (877) 367-1429 for a free inspection and matching assessment.
We remove all tiles carefully, store them on-site in labeled sections, replace the failed 30-lb felt with modern synthetic underlayment or self-adhering membrane, then reinstall the original tiles or matched salvage. This is standard procedure for San Marino’s housing stock - the tiles often outlast multiple underlayment generations. The job cannot be done properly without full tile removal; anyone suggesting otherwise is leaving failed felt in place. We will be there when we say, and we stand behind it - no paperwork, no arguing.
Yes - San Marino’s position at the base of the San Gabriel Mountains amplifies Santa Ana wind events that routinely dislodge mortar ridge caps and loosen individual tiles on steep multi-plane rooflines. We inspect for wind damage after every major event, and our replacements include re-bedded ridge caps with flexible modern mortars and supplemental mechanical fastening where appropriate. If you suspect wind damage, call (877) 367-1429 - a live person answers 24/7.
We source salvage tiles from demolition sites across the San Gabriel Valley - Pasadena, South Pasadena, and occasionally older neighborhoods in Alhambra - to find color and profile matches that satisfy San Marino’s discerning homeowners. This is a sourcing challenge essentially unknown in any adjacent city, and it is why local experience matters. When salvage is unavailable, we discuss custom firing or acceptable close matches with you directly, with full transparency about cost and timeline.
Sometimes - if the underlayment is sound and the damage is isolated to a few broken tiles or a single failed valley, targeted repair can extend the roof’s life 5-10 years. But if the original 30-lb felt is failing, partial repair is throwing good money at a bad foundation. We will tell you straight which situation you are in, with photos from your actual roof to prove it. Our free second opinion on any written estimate ensures you get the full picture before deciding. Done right - and if it is not, we make it right.
