The questions that separate the quotes
You do not need to know roofing to ask good questions. You need to know which questions have answers that can be checked.

Three questions, and up to three San Dimas contractors. Free either way.
Your request is in.
We are matching it now against roofing contractors working in San Dimas 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.
"What underlayment, and how are the valleys done?"
A contractor who enjoys this question is usually the one whose roof lasts. A contractor who deflects it to brand names is quoting a different job.
"What happens if the decking is rotten?"
You want a rate, not a reassurance. Some rot is likely on any older roof and the rate is the only thing that keeps that predictable.
"What is your licence number, and who holds it?"
Then look it up. You are checking that the licence is current and that the name on it matches the name on the contract you are being asked to sign.
"Can I see a job you finished five years ago?"
Anybody can show you a roof completed last month. A roof that has been through five winters shows how the edges, valleys and penetrations were actually detailed.
"Who is actually doing the work?"
Employees, or subcontractors? Both are fine, but subcontracted crews change who carries the workers compensation cover and who stands behind the workmanship warranty.
"What does your workmanship warranty cover, and for how long?"
Material warranties come from the manufacturer and are conditional on correct installation. The workmanship warranty is the contractor's own promise, and it is worth exactly as much as the company behind it.
In short
Write the answers down. Two weeks later, when the quotes have blurred together, the notes are what you will actually decide on.
Related questions
Why does ventilation keep coming up?
It is the most under-sold part of a roof. Trapped heat and moisture shorten shingle life, warp decking, and in cold weather it is what turns snow into an ice dam.
Do you handle commercial buildings?
Yes. Commercial requests go to contractors who do low-slope and flat systems rather than to residential crews. Say so on the property question and it routes correctly.
What if the decking is rotten underneath?
Some of it usually is. The important thing is that the price per sheet is agreed in writing before the tear-off, so the conversation on day two is about quantity rather than rate.
