Flat roof work in Ontario, CA
A pitched roof sheds water. A flat roof is a shallow tray that has to be watertight everywhere at once, which is a much harder thing to build.

Three questions, then the address. Up to three Ontario contractors who do this work.
Your request is in.
We are matching it now against roofing contractors working in Ontario and the surrounding area.
- Today, usually within the hour. The first contractor calls or texts the number you gave us. ASAP requests go out first.
- Up to three of them, no more. We cap it at three so you can compare without your phone melting.
- They come and look. Estimates are given after somebody has been on the roof, not over the phone.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
If you do not hear anything today, check your voicemail and spam folder — contractors often call from a mobile number.
Before you let anybody on the roof
The things worth pinning down on a flat roofing job. A contractor who has not raised them has not looked properly.
- Drain, scupper and overflow provision
- Whether a coating is being sold as a repair
- Whether water ponds anywhere after rain
- Which membrane, and how the seams are joined
- How the flat section is flashed into adjoining walls and pitched roofs
Drains and scuppers need to be checked every season. One blocked drain can hold enough water to matter structurally.
Look at the flashing where the flat section meets a wall. That transition leaks far more often than the field of the membrane does.
Single-ply membranes — TPO, PVC, EPDM — are heat-welded or taped at the seams. The seams and the terminations are the whole job.
Locally
Close behind that: ember intrusion through vents and open eaves. Most houses lost to wildfire are lost to embers arriving ahead of the fire, not to the fire itself.
About flat roofing here
What time of year is best to re-roof in Ontario?
Practically, the long dry run from May to October. Crews are busiest right after the weather turns — November through March — so booking outside that stretch usually buys you a better date and a keener number.
What warranty should I expect?
Ask for both in writing: the material warranty from the manufacturer and the workmanship warranty from the contractor. The second one is the one that matters in year three, and it is only as good as the company behind it.
Are you a roofing company?
No. Summit Roof Pros of Ontario is a free matching service. We do not hold a roofing licence, we do not employ crews, and we never come to your house. We pass your request to independent local contractors who do the work and who you hire directly.
How long should a roof last here?
An architectural asphalt roof is rated for twenty-five to thirty years and, in this climate, tends to land at the lower end of that. Tile and metal go much further, provided what is underneath them is maintained.
What is it going to cost?
No cost, no obligation, and never more than three contractors.
