Help! Roofing felt as temporary leak barrier?
I have a fiber-cement shake roof that's developed a leak above the "witch's" hat for a woodstove, probably due to some slight shifting around of shakes when I replaced woodstove with propane stove. Anyway, I have a small leak that comes into the hearth area -- I used some 24" wide sheet metal under a 3-4' row of shakes, and that seemed to work for a while, but now the leak has traveled and found a new spot to drip down. So, I need to broaden the barrier area beyond/above the sheet metal.
Without wanting to buy yet more sheet metal, could I use roofing felt as a temporary solution until extended dry weather when a roofer can fix the problem? I have some left over from years ago and it seems in good shape. It would be used to shield a 3' x 8-9' area above the "witch's" hat.
I REALLY don't want to go the blue-tarp route!
