Roofing in San Dimas, CA
A 1998 storm record filed under San Dimas describes heavy rain collapsing the roof of a supermarket in Walnut, twelve miles away. The one entry that genuinely belongs to this city is from the same day, 2 September 1998, when a 70-knot thunderstorm gust was logged within a mile or two of the town center. A label on a storm record is not evidence of where the storm was.
The other measured reading is more recent and more useful. On 21 January 2022 a 69 mph gust was recorded at San Dimas, with 68 mph at Marshall Canyon just over the La Verne line. That is a genuine Santa Ana event on the foothill front and it is dated.
Fire is the bigger exposure. The 2002 Williams fire, alarmed 22 September at 38,119 acres, covers about 22 percent of the city, and a further 16 percent of San Dimas is federal responsibility ground that does not appear on the local hazard map at all. That federal ground answers to nobody local.
Of the mapped remainder, roughly 29 percent samples Very High and 21 percent High, against 30 percent non-wildland. Half of this city sits in some hazard class, and where a parcel lands decides whether the covering has to reach Class A or only the statewide Class C floor. Median value is 801,800 dollars.
The stock is 1970s and it is uniform: 3,983 units from that decade and 2,624 from the 1980s out of 12,370, median year 1976, 72 percent owner-occupied. There are also 1,070 mobile homes, close to one unit in nine, which is a separate specification and gets a separate line.
Hillside subdivisions around Puddingstone bring long valleys and steep planes that concentrate water fast in the few real storms this area gets. Valleys are where those roofs fail, so we replace the metal rather than sealing it and run membrane underneath before the tile or shingle goes back. Membrane runs under the new metal, not over it.
San Dimas is climate zone 9, so the cool-roof documentation goes in under a different zone number from the zone 10 paperwork used across the county line. Frank G. Bonelli Regional Park and Puddingstone Reservoir sit at the middle. What to fix now, what to budget for, what to leave alone, in writing.
About San Dimas, CA — and why local matters here
San Dimas sits in Los Angeles County with a population of roughly 34,924, close enough to Fontana that crews move between the two constantly. Local landmarks and corridors residents know well include Frank G. Bonelli Regional Park, Puddingstone Reservoir.
Local knowledge is not a marketing line here. San Dimas properties share soil, weather, permit rules and construction eras with the rest of Los Angeles County, and a roofing contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.

Roofing work we do in San Dimas, CA
Fontana Roof Pros covers the same range of work in San Dimas that we do in Fontana — nothing is carved out because the address is a few miles up the road:
- Roof Replacement — A tear-off is the only moment you get to change how a roof behaves at four in the afternoon in August. Everything after that is maintenance.
- Roof Leak Repair — Most leaks in this city are not caused by rain. They are caused by six months of heat opening a joint, and then found by the first honest storm in December.
- Storm Damage Roof Repair — Storms here rarely create damage on their own. They find damage the summer already did.
- Hail Damage Roof Inspection & Repair — This page exists to talk you out of something. Fontana is not a hail market, and most of what gets called hail damage on an inland roof is heat blistering and ordinary granule loss.
- Wind Damage Roof Repair — Uplift resistance on a shingle roof is mostly adhesive, not steel. The nails hold the head of the shingle; the sealant strip holds the exposed tab flat.
- Roof Inspections — An inspection built for a wet climate looks for water. Ours looks for heat, because that is what is actually consuming roofs in this valley, and heat leaves a different set of fingerprints.
