I have an old gambrel roofed barn that I plan to put a new metal roof on. My plan is to use 2X4 horizontal strapping on 2' centers over the existing wood shake and asphalt shingles. Is this a good option? Can I use 1X4s instead? Or can I attach directly to the existing roof? The roof, over 100yrs, has some swales that I would like to straighten without getting into a lot of roof framing. I would also like to find a rake end flashing that is not as big as the standard pole building rake end flashing. A flashing that allows you to see some of the facia. Any detail ideas?

Dan, Sometimes getting the sags out of a roof takes some roof framing. One thing you can do is run a string line across the roof and then shim your purlins (strapping) over the rafters to match the line. Just be sure and use long enough screws to get a good anchor. If you have a wood shake roof, I would remove it. If you have a wood shingle roof, then you may be able to go over it. Wood shakes are much thicker and rougher than wood shingles. You also can probably use 1x4's, a knowledgeable contractor can look at it and tell you. You can get a sheet metal shop to make the kind of trim you want. We have our own brakes and shears and custom make the trim and flashings for every project. On the gables, our trim usually only covers about 1" of the fascia, about the same as a standard metal edge. We just make what we need and what will look good. You can get the same thing from a metal shop. [email protected]

Wade, I am doing the same renovation on a interlocking shingle gambrel roof. My question is do you need to add purlins or is it a good idea" Pros and cons? Tnanks Thom

Thom, Some metal shingles require battens which could be perceived as a purlin, but it would depend on what brand you are putting on. Here, I would have to tell you like Todd Miller does, check with the manufacturer.
