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.
Get it looked at
Three questions, and up to three San Dimas contractors. Free either way.
You are on the list.
No provider in San Dimas is taking requests through this service yet. We are lining them up, and yours is kept until one can.
- Nobody gets your details yet. Your request stays with us and is not passed to any company.
- One email when someone can help. When a provider covering your area can take it on, we email you once and ask whether you want that company, by name, to contact you.
- Deleted after 90 days. If nobody can take it on, or you do not say yes, your contact details are deleted 90 days after your request.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
Nobody will call you about this request unless you say yes to a company by name.
"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.
