Roofers in Montclair, CA
Roofers in Montclair, CA deal with two forces more than anything else: heat and time. Most homes here were built between the 1950s and 1970s, and many still carry the original wood shake or first-generation composite shingles. After 50 to 70 summers of triple-digit heat, UV exposure, and Santa Ana winds, those roofs are at the end of their life. Call Brennan Roofing at (361) 320-9467 for a written estimate before any work starts.
Why Montclair Homes Are Different
Montclair sits in the Pomona Valley, where summer temperatures routinely pass 100°F. That heat does two things to a roof. It bakes asphalt shingles until they become brittle and lose granules, and it forces attics to superheat when ventilation is weak. The older ranch homes that dominate Montclair were rarely built with adequate intake and exhaust vents, so heat and moisture build up under the decking and shorten the roof’s life from the inside out.
We also see a lot of skip sheathing. Homes from the 1950s and 60s were often framed with gaps between the deck boards, sized for wood shake. When a homeowner wants to switch to asphalt shingles, that decking has to be filled in or replaced before anything else goes down. It’s not a shortcut job, and it changes the labor cost. Homes near the 10 Freeway and along Holton Street often show premature shingle aging from smog and constant heat reflection, so we inspect those closely before quoting.
Montclair code now encourages Title 24 cool-roof compliance on replacements. For many homeowners, that means a reflective shingle or coating instead of a standard dark shingle. It’s a Montclair detail you won’t hear about in the cooler foothill cities nearby.
Our Main Montclair Services
Montclair homeowners most often call us for two reasons: full replacement on an aging roof, or repair after wind and heat exposure. Below are the two services we route to their own pages, plus the inspection option many choose first.
Roofing Company in Montclair
Full replacement in Montclair usually means a tear-off down to the decking, because so many homes still have original wood shake or layered old shingles. We install materials from lines including GAF, CertainTeed, and Owens Corning, and we put the full price in writing before the first shingle comes off. If a roof over a 1960s ranch has skip sheathing, that decking work is part of the quote, not a surprise later. See the full scope on our Roofing Company in Montclair page.

Roof Repair in Montclair
Santa Ana winds lift shingles and tear flashing loose, and the summer heat accelerates sealant failure around vents and pipes. Repair work here often starts with a small leak and reveals worn flashing or cracked shingles beneath. Our crews trace the actual point of entry before quoting, and every repair is covered by the 365-Day Done Right Promise in writing. Details on our Roof Repair in Montclair page.

Roof Inspection in Montclair
Many Montclair homeowners book an inspection before listing a home or after a wind event. We check shingle condition, flashing, attic ventilation, and decking from the inside where accessible. You get a written report with photos and a plain-English list of what needs work now and what can wait. See how we document it on our Roof Inspection in Montclair page.
