Question roofing layers

I am looking at a house that has a newer roof (less than 4 years) however, there are at least 5 layers of shingles. Is that safe? How many layers are acceptable? I live in the midwest where winters are cold and icy and summers get hot!

Three layers are the maximum. With 5 layers, you and a tremendous amount of excess weight on your roof. It it has 5 layers, it is hard to tell the condition of the subroofing, but I have a fair guess. When people roof over old shingles, there is only one reason. They are cheap, cheap, cheap. We will not roof over old shingles. How do you know what your sub roofing is like if you do not see it ?

Getting a house inspection

Many recommend getting an inspection before buying. Although an inspection may not reveal everything and offers no warranty, it can give you peace of mind. You can also have a contingency in the contract that will release you in the event serious problems are discovered.

Jack The Contractor is dead-on, if they were too cheap to tear off the old roofing four times, then you can bet the roofing was allowed to go beyond failure before the new layer was added. The lastest layer sounds like a visual patch for house sale.
