01Are you a roofing company?
No. Cornerstone Roof Pros 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.
02Do you cover the whole Los Angeles County area?
We match across West Covina and the neighbouring communities in Los Angeles County. Put the ZIP of the property in and it will route to whoever actually covers it.
03Why three quotes and not one?
Because one price tells you nothing. Three tells you where the middle is, and the outliers are informative in both directions — the very cheapest is usually leaving something out, and the most expensive should be able to say what you are getting for it.
04What does a new roof cost in West Covina?
Most quotes here for a standard asphalt replacement come in around $12,500 to $31,000. That assumes one layer to remove and sound decking. Every quote you get should say in writing what happens if the decking is not sound.
05Do I have to hire anyone?
No. Take the quotes, sit on them, use them to argue with your insurer, or throw them away. There is nothing to cancel and nothing owed.
06Is this really free?
It is free to you. Contractors pay to receive homeowner requests in their area. That is the entire business model, and we would rather say so plainly than pretend otherwise.
07How long does a re-roof take?
A straightforward asphalt roof on an average house is one to three days. Tile, slate and complex rooflines take longer, and weather stops work more often than anything else.
08Are gutters included in a re-roof?
Normally a separate line. It is the one add-on that genuinely costs less when done at the same time.
09What if the decking is rotten underneath?
Expect a few sheets on most older roofs. Get the per-sheet rate in the contract. Open-ended decking charges are where a fixed price stops being fixed.
10I 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.
11Should I repair or replace?
Rough rule: if the covering has more than about five years left and the damage is confined to one area, repair. If it is at the end of its life or you are patching the third leak in two years, you are paying instalments on a replacement.
12I rent. Can I use this?
Only the owner can approve roofing work. If you are renting, the fastest route is to send this to your landlord or property manager rather than gathering quotes nobody can act on.
13Are 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.
