Thanks! I'll pass that on to my dad, but I'm fairly sure that at this point the roof just needs to be replaced over the porch. It's been there for so long and the leaking just keeps getting worse. But in the mean time, your idea is good!! Maybe we'll do that!
I useto help a friend with roofs when I was younger, and thats moreless a temporary fix, also I forgot to mention, that won't work if it shingles. I was assuming your porch has a tin or some other sort of metal roof.
