I had a 25 year roof installed after my roof was damaged by hail. The original roof had been on about 20 years and was in good shape up to the point the hail beat it to death. This new roof is about 9 years old and I see that its curling (upward) in various sections on the south face of the roof. The roofers want $5700 to do the whole roof and $3K to do the curled face about (20' by 20').
Now since there should be another 15 years left on the remaining 3/4s of the roof and I feel that the $3K is a rip off what I feel I should do is: to re shingle over the
20 by 20 area,,, nailing down the curled corners of the original roof as I shingle my way up the roof shingling right over the existing roof. At $20 per bundle I could do the four square for about $240 bux.I reason that it's not good practice to shingle over shingles but I have seen lots and lots of roofs shingled over shingles and since I'll have to do the rest of the roof in about 15 years, these need only last that 15 years. Doing it this way also allows me to do the roof at a leisurely pace. (I'm old and heavy) [yes,,,,fat!]
What do you think? Does the plan hold water? (No pun)
