San Dimas, CA
The tile is fine. The roof might not be.
Slate and clay are the two coverings that routinely outlive the people who chose them. They are also the two that the wrong crew can ruin in an afternoon.

Three questions, then the address. Up to three San Dimas contractors who do this work.
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.
Before you let anybody on the roof
The things worth pinning down on a tile and slate job. A contractor who has not raised them has not looked properly.
- Whether battens are being replaced at the same time
- The condition and age of the underlayment beneath
- Fastener specification, especially near salt air
- What percentage of tile breakage they expect and how it is priced
- Whether the tile can be salvaged and relaid
Broken or slipped tiles are a maintenance item, not an emergency, provided the underlayment beneath is still sound.
Slate wants copper or stainless fasteners and a crew who has done it before. Steel nails on a slate roof is a hundred-year covering held down by a thirty-year fixing.
Walking a tile roof breaks tile. That is not carelessness, it is physics, and any honest contractor will tell you a small percentage will be lost and replaced.
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 tile and slate here
How long should a roof last here?
An architectural asphalt roof is rated for twenty-five to thirty years and, in this climate, tends to land at the lower end of that. Tile and metal go much further, provided what is underneath them is maintained.
Are the contractors licensed and insured?
Contractors have to give us their state licence number and proof of liability and workers compensation cover before they can receive requests. You should still ask to see current certificates yourself before work starts — a licence can lapse between checks.
What warranty should I expect?
Two separate things. The manufacturer covers the material for its rated life, but only if it was installed to their specification. The contractor covers workmanship, commonly five to ten years, and only for as long as they are trading.
What time of year is best to re-roof in San Dimas?
Practically, the long dry run from May to October. Crews are busiest right after the weather turns — November through March — so booking outside that stretch usually buys you a better date and a keener number.
