Hi all,

I have some shingles (not sure what type) on the house I just bought. The
shingles are about 13 years old. Some of them are starting to curl up a
bit. I'm wondering, how to you know exactly when you should be replacing
the shingles?

Thanks for any info!


I'm surprised the inspector didn't discuss this with you before you bought
the house? Did he get up on the roof to check it?

One sign of need for replacement is brittleness. You'll begin to see
crumbling during high winds. Shingles should be flexible when they're in
good shape.
