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.

While you don’t have to let roofers inside your home, it is proper etiquette to offer the use of your restrooms. And if it’s a hot day, it’s polite to invite the roofers into your house to cool off and have a chilled drink.

The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.
