Roofers in Ontario, CA
Roofing in Ontario, CA is defined by sun, wind, and age. The city’s housing stock leans heavily on tract homes built from the 1950s through the 1990s, and many of those roofs are now facing their second or third covering. Add in the high-UV summers and the Santa Ana winds that hit hardest in the fall, and you get a roofing market where the most common calls are for brittle shingles, lifted ridge caps, and flashings that gave up years ago. If you’re looking for roofers in Ontario who understand those specific conditions, call us at (562) 315-0297 for a free estimate.
Why Ontario Homes Are Different
Ontario sits in a hot semi-arid climate. That means the roof gets baked, not soaked. Prolonged sun destroys asphalt shingles faster here than it does in coastal areas, because the granules that protect the shingle surface break down under constant UV exposure. Once the granules go, the asphalt underneath begins to crack and curl. In neighborhoods off Euclid Avenue, where many homes date to the 1960s and 1970s, it’s common to find original wood shake or older composition shingles that have become brittle enough to snap when a Santa Ana wind event pushes through in October or November.
The housing stock tells a similar story. Central Ontario has a large share of single-family tract homes with low-slope or composite shingle roofs, many of them now past their intended service life. Newer developments in the south and east of the city tend to have tile roofs, which hold up better against sun but still need attention when the underlayment beneath them ages out. After a strong Santa Ana event, roofers in Ontario consistently see a spike in calls for missing shingles and lifted ridge caps, especially on older homes near the historic downtown area where roofs were often installed with minimal fastening. That’s not a random pattern. It’s a predictable consequence of how those roofs were built and what the wind does to them.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: something is leaking, or the roof is at the end of its life and needs to be replaced. Both jobs have their own page in Ontario, with local pricing and specifics.
Roofing Company in Ontario
When someone searches for a roofing company in Ontario, they’re usually deciding whether to repair or replace. We walk through the roof’s condition, age, and the materials already in place, then give you a written price before any work starts. Ontario’s sun and wind patterns factor heavily into that recommendation. A roof that might last another five years in a milder climate often doesn’t have five safe years left here.

Roof Repair in Ontario
Roof repair in Ontario usually means one of three things: a leak around flashing or a vent, missing shingles after a wind event, or failing seals on an older roof that’s not quite ready for full replacement. We identify the exact source of the problem, explain what we found in plain language, and complete the repair with a written guarantee before the crew leaves. If the repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. Roof Repair in Ontario
Roof Replacement in Ontario
Full roof replacement in Ontario is a bigger decision, and the local climate makes material choice matter more than it does elsewhere. Asphalt shingles from quality manufacturers like GAF, Atlas, or CertainTeed hold up well here when installed with wind-resistant underlayment and proper fastening. For homes in the southern part of the city where tile roofs are common, we also handle tile replacement and the underlayment work beneath it. Every replacement gets a written price, a written guarantee, and a full year of accountability after the job is done. Roof Replacement in Ontario

What pushes a price toward the higher end in Ontario is usually access and roof condition. Steep pitches, two-story homes, and older roofs with multiple layers to tear off all add labor. The one thing that doesn’t change is the price you’re quoted. We put it in writing before any work begins, and that’s the number you pay. No change orders at the door. Greg Holloway runs the Tilehurst Roofing team here in the Inland Empire, and the written price is non-negotiable policy on every job.

What Ontario Customers Say
"Full replacement after the last hail storm. They wrote up everything, worked with my insurance, and the crew cleaned the yard so well I couldn't find a single nail. Done in two days like they said."
- Lauren Petrakis"They repaired a spot that another company had "fixed" twice. Tilehurst found what the others missed and it finally stopped leaking. Should have called them first."
- Denise Ackerman"Small leak around the chimney flashing. They sealed it properly and it's held through a wet winter. Didn't push me toward a whole roof like the last outfit tried to."
