Question Tear off old or install new over old??

My cousin's roof has only one layer of shingles that are about 15 years old. The shingles are in pretty poor shape in parts of the roof and are buckling up. In some cases the actual asphalt from the shingles is gone and just the back of the shingle is left.

Can you put a new layer of shingles over this or would you tear off then install new?

Thanks for any help!!

Rip them off. If they are buckled now, imagine what the new shingles will look like when they are installed over it. Plus you can't inspect the decking for any damage if you don't rip the old roof off.

I'll put in a vote as well...
Tear it all off and have it done right.....

The only reason to double up is for a color change on perfectly good shingles, or when theres just absolutely no way it will fit the budget...and that second one isn't all that good a reason. Replacing sheetrock and rotted framing is more expensive than pulling off the old roofing.

Well... for starters, real-world a roof-over is pretty much a complete out for the manufacture in terms of warranting shingles against manufacturing defects...

Thumbs up Thanks!

I was thinking the same thing. She doesn't plan on living there much longer (But who knows in this economy), and wanted to just get it done.

I'm doing the roof for her so it's only going to cost her the amount for a dumpster.

Thanks for the input!!
