What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

No cost to you. Contractors pay us, you do not.

Coverage does not stop at a boundary line. If you are just outside it, the ZIP on your request is what decides who gets it.

Behind it: wind-blown embers landing in the valleys. Class A assemblies and closed-off vents matter more here than the colour of the shingle.

Most asked for around here: tile and slate roofing

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.

Questions

Is moss on the roof a problem?

Yes, eventually. Moss holds water against the shingle and lifts the edges as it thickens. Zinc or copper strip at the ridge suppresses it. Pressure washing an asphalt roof strips the granules and does more harm than the moss did.

What warranty should I expect?

Ask for both in writing: the material warranty from the manufacturer and the workmanship warranty from the contractor. The second one is the one that matters in year three, and it is only as good as the company behind it.

Are you a roofing company?

No. Cornerstone Roof Pros is a free matching service. We do not hold a roofing licence, we do not employ crews, and we never come to your house. We pass your request to independent local contractors who do the work and who you hire directly.
