We're going to have our roofing replaced with new shingles because a few shingles would go off when there are strong wind in the spring each year. We have spend ~$75 to have them repaired. My wife thinks the old roof (~10 years old) is not of high quality and it needs to be replaced.

We had 2-3 roofer estimated and the cheapest one would put the new shingles on top of the old ones. I wonder if there is any disadvantage doing it this way?

Also, will a new roof be able to stand the strong wind in next spring? We live in Cincinnati.

Thanks for your help,

Hi waterfall_zen,

If you're going to live in the house for the next 30+ years, I'd get a 30 year shingle AND have the existing shingles removed. If you're going to move soon, then just go over top.

There are Building Code issues. Make sure your roof can carry the WEIGHT of the 2 layers. The disadvantage is that the top layer may not lay very well on top of the bottom layer. If the bottom layer is EXTREMELY aged, I'd definitely remove it.

Wind is a problem in a lot of places. That's why I recommend a heavy shingle such as a 30 year shingle. You can always use a dab of black roofing caulk under the first few rows of shingles at the roof line and rake edges to help keem them down.

My best to ya and hope this helps.

You might ask the other roofers why they don't consider laying over the old.
It is accepted and common in some parts of the country and viewed with disdain in others. There are definitely judgement calls to be made by the installer.

Most manufacturers will void the warrantee on new shingles if you make a claim when the shingles are applied over and older roof.
