Hello,

We are about to undergo a fairly substantial renovation project. The plan is to remove our third floor and to replace it with a mansard. A portion of the roof will be flat. There will be a sloped area (like a hipped roof) that connects to the vertical portion of the mansard. We'd like to use slate on the visible parts of the roof. Can you recommend a material for the flat part of the roof, and can we feel confident that it won't leak? We live in the Northeast.

Thanks for your help.

Yes, you can either go with a flat pan (locked and soldered) 20oz. copper roof or stainless steel. Also there is terne metal roofs that hold up. And lastly a EPDM or PVC roof. Most people today that want the look of slate and spend the $ on that rather than the flat roof they usually go with a EPDM rubber roof. You will get about 20-25 yrs. out of an EPDM rubber roof whereas with the copper, stainless or terne metal(s) you will get somewhere around 75-90 yrs. With terne metal you usually end up coating or painting the metal with copper and stainless you do not have to (nor is it reccommeneded) coat or paint. Just my take on this subject. A TRUE SLATE AND COPPER ROOFER The length roof last also has one more important issue no matter what type of material you use it has to be INSTALLED CORRECTLY.

Go with either 20 ounce copper or terne coated stainless steel lock-seam soldered roofing.
