My house is 17 years old, we are the original owners. There are no leaks but the original strip shingles are starting to curl up. Roof has two pretty steep valleys that are wearing down through the shingles. I live in the country with a farm field surrounding, with nothing to stop the wind. Should I just replace the roof completely or re-shingle?
The asphalt roof on our Oregon house is 20 years old and it looks like there's another layer underneath. The roofing is beginning to come apart in places and curl up in other spots. Should we have the whole roof removed and reinstalled with a new one--or can we tell the contractors to just add another layer on top of the old roof?
