Our covered patio has a corrugated roof, but it leaks at the joints where the corrigation comes together. We did not install this roof, and the holes between the sheets are quite large.
I would like to fix this the easiest and cheapest way (as long as it will last for a few years). I was thinking of laying another layer of corrugated roofing on top, making sure to cover the holes. My husband is afraid the waves in the corrugation won't be the same width as those on the existing roof, causing all kinds of problems. Any ideas? Please help. Although we are handy with things, neither one of us is experienced at building complicated projects.
