Norco, CA
Flat roofs do not shed water. They hold it back.
Almost every flat roof problem is a drainage problem wearing a disguise. Standing water finds the one seam that was not welded properly.
Describe the flat roofing job
Three questions, then the address. Up to three Norco contractors who do this work.
Your request is in.
We are matching it now against roofing contractors working in Norco 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.
- Whether water ponds anywhere after rain
- How the flat section is flashed into adjoining walls and pitched roofs
- Drain, scupper and overflow provision
- Which membrane, and how the seams are joined
- Whether a coating is being sold as a repair
Look at the flashing where the flat section meets a wall. That transition leaks far more often than the field of the membrane does.
Drains and scuppers need to be checked every season. One blocked drain can hold enough water to matter structurally.
Modified bitumen is the rolled, torched or self-adhered system you see on older flat additions. Cheaper, and shorter-lived.
Locally
Behind it: morning fog that sits on the roof until mid-morning. It is why two identical houses on the same street can be ten years apart on the same roof, depending on which way they face.
About flat roofing here
I have solar panels. What happens to them?
Panels have to be detached and reset. Budget for it separately and coordinate the two trades. Never put a new solar array on a roof with under ten years left.
Should I take the cheapest quote?
Not automatically. Put the quotes side by side on layers, not on totals — underlayment, ice-and-water, drip edge, valley treatment, ventilation, decking allowance, warranty. Cheap usually means less of those, not the same roof for less money.
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.
How long should a roof last here?
Rated life and real life are different numbers. Here, ordinary rated life is a fair guide, provided the attic breathes. Ventilation and the quality of the installation move that more than the brand does.
