Is a metal roof worth it here?

The metal itself almost never fails. The fasteners, the panel movement and the detailing at the edges are what decide how the roof ages.

What best describes your home?

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

Free. You are not committing to anything.

Before you let anybody on the roof

The things worth pinning down on a metal roofing job. A contractor who has not raised them has not looked properly.

  • Panel gauge and the coating warranty
  • Whether the crew installs metal regularly or occasionally
  • How the panels are allowed to expand and contract
  • Standing seam or exposed fastener, and why
  • How valleys, ridges and penetrations are detailed

Noise is the question everybody asks. Over a solid deck with underlayment, a metal roof is not meaningfully louder than shingle. Over open purlins it very much is.

Standing seam hides its fasteners under the seam. Exposed-fastener panel is cheaper and relies on hundreds of neoprene washers that have to be revisited every decade or so.

Ask to see a standing-seam job they finished more than three years ago. The edges and the valleys will tell you everything.

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 metal roofing here

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.

It is leaking right now. What do I do?

Move what you can out of the way, put a bucket under it, and if there is a bulge in the ceiling put a small hole at its lowest point to let the water out in one place rather than bringing the whole panel down. Then mark your request as an emergency — those go out first.

How long does a re-roof take?

A straightforward asphalt roof on an average house is one to three days. Tile, slate and complex rooflines take longer, and weather stops work more often than anything else.
