Metal roofing in West Covina

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.

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

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.

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

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

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.

A light-coloured metal roof reflects a serious amount of heat, which shows up on a summer power bill in hot climates.

Locally

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.

About metal roofing here

Do I need a permit?

Yes, in nearly every jurisdiction a re-roof is permitted work. A contractor who suggests skipping it is telling you something useful about how they work.

How long should a roof last here?

Rated life and real life are different numbers. Here, ordinary rated life is a fair guide, provided the attic breathes. Ventilation and the quality of the installation move that more than the brand does.

How much deposit is normal?

Ten to thirty per cent is ordinary, and is often used to order material. A demand for full payment up front is a reason to walk away.

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.
