Replacing a roof in San Dimas: what it takes
Replacing a roof is four days of noise and one decision that lasts thirty years. It is worth an afternoon of comparing.
Describe the replacement job
Three questions, then the address. Up to three San Dimas contractors who do this work.
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.
Before you let anybody on the roof
The things worth pinning down on a replacement job. A contractor who has not raised them has not looked properly.
- A written per-sheet price for replacing bad decking
- Who pulls the permit, and what the inspection schedule looks like
- Which underlayment, and whether ice-and-water goes on the eaves and valleys
- Tear-off or overlay, and what the local code allows
- Ventilation: what is there now, what it should be
Insist on knowing what happens to decking that turns out to be rotten. The good answer is a per-sheet price agreed in writing before the job starts.
Ask how long the crew has been together. Roofing is a trade where the same company name can mean an entirely different set of hands from one season to the next.
The covering is the part you can see and the part everybody quotes on. The parts that decide whether the roof lasts are underlayment, ventilation, drip edge and how the valleys are handled.
Locally
The second problem is the marine layer keeping the north slope damp. Damp that arrives every morning and leaves by lunchtime is worse for a roof than rain, because nothing ever fully dries between one and the next.
About replacement here
Is 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.
I 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.
What does a new roof cost in San Dimas?
For a typical San Dimas home of about 25 squares, an architectural asphalt re-roof usually lands between $13,000 and $27,000. Tile, slate and standing-seam metal run well above that. The number moves on how many old layers come off, how much decking is soft underneath, and how easily a truck can get to the house.
Should I take the cheapest quote?
Only if it is the same roof. Most large gaps between quotes are scope gaps. Ask the cheapest contractor which of the other quotes items they have left out, and why.
