Metal roof over shingles
 

I have 2 roof on my house now & am thinking about putting a metal roof on
without tearing the old roof off. Would this be dangerous. The roof is pretty
steep, cant walk it.

IF you can't walk it, how to you propose to put a metal roof on top
of it?


Hire illegals, they will get it done.

It's against code to do more than two layers here.

Another factor is that 2 layers of shingles means the roof is typically
50+ years old. The only way to accurately assess the condition of the
decking is by removing the shingles. If there is some rotted decking,
he'd be putting a new, expensive metal roof over rotted wood. I'd
run from any roofer that offered to do the job that way. I would not
even do a second layer, let alone three.

Why? Like refried beans. If you don't like them the first time, why
cook them again?

Did this to my house 10 years ago. Worked fine. No problems since. And
the electric bill went down as did the insurance bill.

The constraint of no more than 2 layers is based upon asphalt singles and the total load on the roof. Regulations vary by state and town. The added cost to remove the shingles and dispose of them shouldn't be too much in the overall scheme of things. Take the opportunity to examine the decking of the roof and fix any problems now. finding them after the metal installation will incur a much higher cost to repair (possibly more than the cost to remove the shingles now).

Also, with only the metal roof, the load capability of the roof will be higher for things such as snow (if you get snow).

Overall, I would remove any existing roofing prior to installation of the metal roofing material. You will get a better roof.

With most metal roofs the buildup of snow is no problem. The smooth
surface of the roofs will cause the snow to slide off depending on
the angle of the roof.
