Commerce, CA
Is a metal roof worth it here?
A metal roof costs roughly double a shingle roof and lasts roughly three times as long. Whether that is a good trade depends entirely on how long you are staying.

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.
- Standing seam or exposed fastener, and why
- How the panels are allowed to expand and contract
- Whether the crew installs metal regularly or occasionally
- How valleys, ridges and penetrations are detailed
- Panel gauge and the coating warranty
Ask to see a standing-seam job they finished more than three years ago. The edges and the valleys will tell you everything.
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.
Locally
Behind it: shaded slopes that never really dry out. Damp that arrives every morning and leaves by lunchtime is worse for a roof than rain, because nothing ever fully dries between one and the next.
About metal roofing here
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.
Can I stay in the house while it is done?
Most people do. Expect noise from early morning, dust in the attic, and a day where the driveway belongs to the crew.
Why three quotes and not one?
Because one price tells you nothing. Three tells you where the middle is, and the outliers are informative in both directions — the very cheapest is usually leaving something out, and the most expensive should be able to say what you are getting for it.
Why does ventilation keep coming up?
Because a badly ventilated attic cooks the roof from underneath and takes years off it. Intake at the eaves and exhaust at the ridge, in balance. It is cheap during a re-roof and awkward afterwards.
