Chino Hills, CA
Flat roofs do not shed water. They hold it back.
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.
Describe the flat roofing job
Three questions, then the address. Up to three Chino Hills contractors who do this work.
Your request is in.
We are matching it now against roofing contractors working in Chino Hills 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.
- How the flat section is flashed into adjoining walls and pitched roofs
- Which membrane, and how the seams are joined
- Whether water ponds anywhere after rain
- Whether a coating is being sold as a repair
- Drain, scupper and overflow provision
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.
Single-ply membranes — TPO, PVC, EPDM — are heat-welded or taped at the seams. The seams and the terminations are the whole job.
Locally
Behind it: shaded slopes that never really dry out. The north side of a house here ages years faster than the south side, and almost every roof gets replaced because of it.
About flat roofing here
Are gutters included in a re-roof?
Usually not, unless the quote says so. If they are near the end of their life, replacing them during the re-roof is meaningfully cheaper than doing it later, because the crew and the staging are already there.
Are the contractors licensed and insured?
We require a licence number and current insurance from every contractor in the network. Verify it yourself anyway. Your state licensing board has a free lookup, and it takes two minutes.
How many contractors will contact me?
Up to three. That is a hard cap, not a guideline. Three is enough to compare and few enough that your phone stays usable.
Should I repair or replace?
It depends almost entirely on how much life is left in the material. Ask any contractor who inspects it to give you a number of years and a reason. If two of them independently say the same thing, believe it.
