I have a mansard roof over my garage apartment. The roof is currently slate and is in need of repair or replacement. I would like to replace the existing slate with standing seam, but i wonder if this is possible because the sides of the mansard roof are concave, so my first question is "Can this be done?" Also, I have never put a roof on a house before and wonder if I can do the work myself. The garage apartment is approximately 600 square feet, total roof area is probably around 1200 square feet and has eight dormer windows.

Grant, I am not quite sure I understand your situation. Generally, I would say that many metal products are suitable for what you have. If you wish, please send me photos at [email protected] and I will provide further input. Todd

I responded to your message regarding my Mansard roof last week by email and haven't heard back. Did you receive my email and pictures? Grant

Hi Grant. That is odd. Yes, I did receive your email and I responded back. Let me look through my "sent" folder at work and try to re-send. Sorry about that.

I had an idea I thought would be effective; tell me what you think. Could I use corrugated metal roofing on the mansard roof I sent you pictures of? If I did decide to do this, could I nail it in over the existing slate?

Corrugated roofing is installed with screws. There are self-drilling screws which might work. How badly the slate breaks up when you do this is unpredictable. If it breaks up real badly, I would not proceed. As far as putting corrugated roofing on this, It is not going to bend to match the curve. It will somewhat span over the curve so you would have to be careful not to overdrive fasteners across the curve.

What about the idea of using sheets of metal, essentially the corrugated stuff, flattened?

Various corrugated profiles of roofing sheets maintain watertightnees at fasteners and seams based upon their design. It probably would be possible to use flat sheets on what you have. I am not sure how attractive it would be be though. You would need to use some screws as through-fasteners and use fairly heavy gauge metal to avoid oil canning and problems around the fasteners. I would suggest folding a flat interlock on the vertical seams. Experienced sheet metal contractors would be good for this type of work though they might prefer to fold panels with a raised seam rather than a flat seam.
