Metal roofs- opinions, please

We also have a metal roof and I would not have it any other way. Goes up easy, almost no maintenance, inexspensive, light weight, sturdy, and will outlast any shingle made.

I have an acquaintance that is an LEED certified architect, who has advised me not to use metal; yes, they are sturdy and the warranty is fantastic, but his concern is that the weight can cause problems and suggests that the newer plastic roofs , especially since I am going to implement photovoltaics.

I love the sound of the rain on our corrugated iron roof....would never have anything else.

Weight ?!?

Okay, that could be.

Mine are 22 foot by 4 foot panels, I lifted each one, carried them to the building, I did not carry them up the ladder, as it was a bit windy, so I leaned them against the eave and from up on the rafters I pulled each one up onto the roof and set them in place. Each panel that I used was maybe 40 pounds.

22 foot times 4 foot is 88 square foot of roof, divided by 40 pounds, would mean that each square foot of roof is approximately 0.45 pounds.

Now my roof line has a pitch of 1 foot drop per 10 foot horizontal run. So it is almost a flat roof. And it is rated for 80 pounds of snow load per foot. So it is fairly strong.

So is your buddy saying that steel weighs too much with it's 0.45 pounds per square foot?

Or is he saying that holding a snow load of 80psi is not strong enough, to hold a photocell panel also?

Inquiring minds want to know.

Standing seam steel roof over old shingles.

Cons:
Requires painting.
Insurance was quite the challenge.
A bit noisy in heavy rain.
Quite noisy in strong winds
Snow all comes off in one thump, you don't want to be under it

Pros:
I can paint it any color I want
No real maintenance
I like the noises it makes
Snow all comes of in one thump, no ice dams

Yours did not come with a baked-on enamel finish? Mine did.

We have no insurance, on our home. Perhaps it may be an issue, I have no idea.

If you insulate the roof, it should lessen the ROAR a lot.

We did experience noise from high winds, when there were still a few openings and before each sheet was securely sealed to it's neighbor. This last week, we had some high winds that blew down a lot of trees, and our TV antenna came down. But we had no whistling.

If I were you, I would check with my insurance company before I buy. We have metal roofs and love them, but they can be more expensive to insure if they are not hail-resistant. At least, that's the way it is in Oklahoma.

This is a good site to do research and have your questions answered. The guarantee on a metal roof is on the paint, that's all. The installation in most cases is the biggest problem as most don't or can't do the job properly and don't use all the right materials. Metal expands and contracts, sweats and dents. It is also very slick to walk on especially when weathered, the dust and dirt make it slipperier.
