Glendora, the Pride of the Foothills, has three roofing zones. North Glendora's foothill neighborhoods and citrus-era homes sit in very high fire hazard severity zones — the Colby Fire in 2014 burned homes here — and take strong down-canyon winds. The Village and the streets around it hold 1900s–30s homes. South of the 210, the tracts are 1950s–70s with converted shake and layered shingle, and South Hills and Morgan Ranch add hillside tile.
Fire-zone re-roofs, wind repair, historic-home roofline work, converted-shake tear-offs, and large custom roofs in the foothills are our Glendora specialties.

Fire hazard zones: Parts of Glendora are mapped as a Very High Fire Hazard Severity Zone by the California Office of the State Fire Marshal. Inside those zones a re-roof must use a Class A fire-rated roof covering (California Residential Code R902.1.1), and we recommend ember-resistant vents and the other Chapter 7A details whenever vents or eaves are replaced.

GLENDORA ROOFING FAQ

How do I choose the best roofing contractor in Glendora?
Check four things before you sign anything: an active California contractor license you can look up on the CSLB website (ours is CSLB #1149997), a manufacturer certification such as GAF Certified, a real local office (Stone Ranch Construction is at 711 W 17th St, Unit G-2, Costa Mesa, about a drive up the freeway from Glendora), and a free on-the-roof inspection with a written estimate that names the materials.
