Anyone do metal roofing?

[margomaps]

I once got an estimate for a new metal roof on a moderately sized single family home.  $30k.  The estimate to put a new asphalt roof on top of my old one was $6k.

FWIW, my roof had some water damage too.  I paid a roofer about $500 to remove and replace a 4'x4' section of the rotting plywood sheathing and install new shingles.  And install a new ridge vent and fix some gutters.  Roofs with some water damage can be a stressful thing to worry about.  But in the end it's not very complicated or expensive to have it fixed if you find a competent and fair contractor.  THAT can often be the hardest part.

The problem is not "rotting plywood sheathing" as water encroachment from ice dams is not a constant thing that would rot the wood per se as it dries out once the snow/ice melts. The problem is ice dams with asphalt roofs from the lack of insulation and an effective air barrier.

As I said, a metal roof doesn't address the problem of insulation/air barrier - (as he said) it just allows the snow to slide off the roof removing the source of water to encroach.

Also, his asphalt roof may need to be removed depending on the number of layers present which could add significantly to the cost.

Yes!  The third layer will not be allowed and, of course, all of the proper permits must be begged for and all inspections made because you're in...Keene!

In Grafton,  one just puts a new roof on.

Would you recommend putting on a 4th roof over the 3rd?

No, I don't recommend the third.  I have seen a foundation crack the night after the shingles for the fourth layer were stacked on the ridge.  For the record, it wasn't me.

Probably not, but, there is no bureaucrat to stop me.

Most people have no idea how much an asphalt shingle roof actually weighs.

Toss them a bundle of shingles, then tell them to multiply times three for every 10'x10' section of roof.

If your foundation cracks over an additional layer of shingles, your problem is your foundation.

what if you had a party ... and they brought drinks?

Well...  No, This thing had one layer of wood shake and three layers of thick composite shingles then the guy went and stacked all the shingles for the fourth layer pretty close together, it was a small crack, you can only ask so much from block of concrete.
