San Marino design review and its effect on a new roof
San Marino divides into seven zones based on minimum lot size, from about 4,500 square feet to well over 30,000. Most homes date from 1920 to 1950 and were built as Period Revival designs rather than repeating tract plans. The city also applies strict design review and zoning, so a roof change that would be routine elsewhere may need approval here.
Start with the city, not the product catalog. Ask City Hall what a re-roof requires at your address, then pick the material and color that fit. As its own city inside Los Angeles County, San Marino keeps a separate government, so a Los Angeles or county quote template may not fit.
Clay tile, aged underlayment and flashing on 1920s San Marino homes
Clay tile lasts a long time. The felt underlayment beneath it does not. On a house of this age, leaks usually come from dried underlayment, rusted valley metal or failed flashing at chimneys and walls, while the tile itself stays sound. That is why a leak on a tile roof can look like a tile problem and be something else.
A careful repair lifts the tile by section, replaces what is beneath, and sets the same tile back. Broken pieces are matched in profile and color. The state residential code does not permit roofing over clay tile at all, which means a full replacement removes it down to the deck.
Large lots, mature trees and roof access in San Marino
Big lots mean big roofs. Hipped roofs with many ridges and valleys put a lot of seams in the weather, and mature oaks and camphor trees overhang many of them. Leaves collect in valleys and gutters, and older homes often have built-in gutters in the eave rather than hung ones, which can overflow into a wall before anyone notices.
We protect landscaping, stage materials away from planting beds and explain how the crew will get on and off the roof. Our gutters page covers the options for built-in runs.
Huntington Drive, Lacy Park and the gardens: who sees your roof
San Marino is small, about 3.8 square miles at roughly 564 feet, and its landmarks are close together. The Centennial Clock stands on Huntington Drive at San Marino Avenue, across from City Hall. Lacy Park covers about 30 acres in the middle of the city, bought in 1925, and the Huntington gardens span around 120 acres. The Crowell Public Library opened in 2008.
On a street this visible, a roof is seen by neighbors and by the city, so the finished look matters as much as the leak fix. The 2020 census counted 4,482 housing units, and many lots average over 30,000 square feet. Before ordering tile or underlayment, we suggest asking City Hall what it needs at your address, and keep any approval letter with the contract.

Roofing questions from San Marino
Does San Marino's design review apply to a re-roof?
The city has strict design review and zoning, and it has fostered historic preservation, so ask City Hall before choosing a material, color or tile profile. Rules can differ by property and by the scope of work. Your contract should name who handles any approvals, and we will work to the details the city confirms.
Can a San Marino tile roof be repaired instead of replaced?
Often, yes. Clay tile frequently outlives the underlayment beneath it, so the usual fix is to lift the tile, replace the underlayment and flashing, and set the sound tiles back. Cracked or missing pieces get matched as closely as possible. Re-laying costs less than new tile when most of the tile is reusable.
Can we switch a San Marino tile roof to asphalt shingles?
It may be possible, but design review could limit it. Tile and shingle also weigh and drain differently, so the deck and flashing need review. Talk through the city's view first. Van Nuys customers describe a tile-to-shingle switch on their own homes, and we would price both options so you can compare.
Services in San Marino
- Roof Repair
On a 1920s tile roof, the leak often starts in the underlayment or the valley metal, not in the tile. Working one section at a time can keep the original tile in place.
- Roof Replacement
Strict design review means the material, color and profile are worth settling with the city before work starts. We price the replacement around what the city confirms for your address.
- Roofing Materials
Period Revival homes depend on the roof's look as much as its performance. We walk through tile, metal and shingle options, how each weighs and drains, and which ones suit an older deck.
- Gutters
Mature trees and older built-in eave gutters make drainage a recurring San Marino problem. New or relined runs, and clean downspouts, keep water off plaster walls and window trim.
- Tile Roofing
Clay barrel tile is part of what makes a San Marino Period Revival house look right. This page explains clay versus concrete, weight, and how lift-and-relay keeps sound original tile in place.
- Tile Roof Repair
A stain on a 1920s San Marino ceiling often traces to dried underlayment or valley metal, not the tile. Sectional repair lets us renew what leaks and set the original tiles back.
- Tile to Shingle Conversion
Some owners ask about swapping tile for shingle. In a city with strict design review, the city's view comes first, and the deck must be checked for the weight and drainage change.
