Replacing your roof is expensive. This is why many choose to install asphalt shingles. It is one of the cheaper alternatives you can find for roofing, and it is also easy to install, remove and maintain. Cared for properly, it can last about 20 years, which means you don’t have to replace it too often. When installing new shingles, you can even install them on top of the existing ones and still make it look good. There are some things to keep in mind to ensure your roof lasts as long as possible, however.
Since asphalt shingles have a textured surface, mold and moss can start growing on the roof and damage it. You have probably seen roofs that have green areas covering it. Moss can seriously damage your shingles, so you should remove it as soon as you see it. Cut back branches that give a lot of shade to the roof and provide moisture. For cleaning off mold you can use a 50/50 solution of bleach and water and scrub your roof down.
