I had at least 2 layers when I had my roof replaced in 2005. But I may have had 3? I know for certain that I'd reached the limit so that all prior layers had to be removed before the new shingles went on.Exactly. I've heard of more than 2 layers where I live but the weight of 3 layers of shingles and snow....
It is always preferable to replace everything. Crew is already up there, added cost is relatively small. They can inspect and repair subroof as needed instead of letting hidden problems worsen for more years. Adding a layer just masks any underlying problem, and adds thousands of pounds extra stress on the house.
