Tile and slate roofing in Ontario
Tile roofs fail from underneath. The tile you are looking at can be in perfect condition over underlayment that gave up a decade ago.

Three questions, then the address. Up to three Ontario contractors who do this work.

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.
- The condition and age of the underlayment beneath
- Whether battens are being replaced at the same time
- Fastener specification, especially near salt air
- Whether the tile can be salvaged and relaid
- What percentage of tile breakage they expect and how it is priced
Broken or slipped tiles are a maintenance item, not an emergency, provided the underlayment beneath is still sound.
Matching discontinued tile is the real constraint. Salvaging what is there is usually cheaper and always closer.
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.
Locally
Close behind that: ember intrusion through vents and open eaves. Most houses lost to wildfire are lost to embers arriving ahead of the fire, not to the fire itself.

How quickly will someone call?
Most requests are picked up the same day, often within an hour. Emergencies are prioritised. If you have not heard anything by the next morning, check voicemail — contractors usually call from a mobile.
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.
What happens to my information?
Your details are passed to up to three local roofing contractors so they can quote. That is the only use. You can ask us to delete them at any time, and there is a do-not-sell page for exactly that.
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 is it going to cost?
Free, no obligation, and your details go to no company until you say yes.
