What best describes your home?

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

Free, and no obligation to anyone.

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.

  • Ventilation: what is there now, what it should be
  • Who pulls the permit, and what the inspection schedule looks like
  • A written per-sheet price for replacing bad decking
  • How the site is protected, and who cleans up the nails
  • Which underlayment, and whether ice-and-water goes on the eaves and valleys

Two quotes at the same price can be very different roofs. Compare the layers, not the brand name on the shingle.

A proper replacement is a tear-off, not an overlay. Going over the top of the old roof saves money on day one and costs it back at the next replacement, when there are two layers to remove and no way to inspect the deck.

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.

Locally

Then, less dramatically: ember intrusion through vents and open eaves. Class A assemblies and closed-off vents matter more here than the colour of the shingle.

About replacement here

Can I just put a new roof over the old one?

Codes in most places allow two layers. That does not make it wise. You lose the chance to see the deck, and the next roofer has twice as much to remove.

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.

Do you handle commercial buildings?

We do. It is a different set of contractors — commercial and low-slope work is a separate trade from residential re-roofing — so answering the property question accurately matters.

I have solar panels. What happens to them?

They come off and go back on, and that is a separate cost, often handled by the solar installer rather than the roofer. If the roof is near the end of its life, do the roof first — removing and refitting panels twice is money wasted.
