You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.

The easiest way to tell if your roof vent boot is leaking is to look in your attic for signs of water damage. You might see visible moisture, water spots, or mold on the roof decking around the roof vent or damaged or soggy insulation below it. If you don’t have access to your attic or aren’t sure if the vent boot is the issue, hire a professional to come inspect your roof and figure out the underlying issue.

A roof overlay will last an average of 15 years, compared to the 20 to 30 years or more that a full roof replacement for a shingle roof will last. An overlay’s lifespan may be shortened even further if there’s underlying damage to the existing roof or structural problems with the roof supports.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.
