We are matching it now against roofing contractors working in West Covina 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.
No part of Cornerstone Roof Pros climbs on a roof. We are a matching service: you describe the job once, and licensed local contractors who actually do that kind of work decide whether to quote it.
West Covina sits in Los Angeles County with a population of around 106,920. The sea is around 28 miles away: near enough to drive the wind, far enough that corrosion is a secondary concern. There is space between houses, which helps access and hurts nothing except the total area to cover.
The failure that leads here is sudden dry winds that test every lifted edge on the roof. These winds are not constant, which is the problem. A roof gets nine quiet months and then one night at fifty miles an hour, and whatever was marginal goes.
Why this exists
Most people do this once or twice in their life, under time pressure, with water coming in. That is the worst possible moment to be comparing advertising. Contractors have the mirror-image problem: they pay to be seen by people who are years away from needing them.
The job this does is narrow on purpose. Three questions and an address is enough for a contractor to say yes or no, and three contractors is enough for you to compare.
How we make money
The money comes from contractors buying introductions, and from nothing else. You are never billed, and there is no second product waiting behind the first. If you would rather not be introduced to anybody, the checklist is here to use without filling anything in.
