When your whole roof or a section of it is overhung by a tree, the shingles can break down more quickly. This is due to the moisture that the tree "traps" on the roof since it blocks air circulation and sunlight. The tree can also litter organic material, like leaves and twigs, onto the roof leading to moss and algae growth. What is important to remember is that the tree won't just affect the existing roof. It will also affect the new roof you put on your home. To minimize damage and difficulties, follow these tips when replacing a roof overhung by trees.
If you don't mind the look of a metal roof, it's a smart choice for your home. The metal won't grow moss like a shingle roof will, and it's less prone to moisture damage. You may need to have the metal re-coated with a corrosion protecting layer more often when it's shaded by the tree, but as long as you do this every 5 - 10 years, it should remain in good shape.
Keep in mind that metal roofs are more attractive than they used to be. If you don't like the shiny tin look, there are colored metal roofs and even some that are painted to look like shingles or wooden shakes.
Think about zinc-infused shingles.
If you do not like the idea of a metal roof, at least make sure the shingles you choose are designed to fight against algae growth -- one of the biggest threats to roofs that are overhung by trees. Shingles embedded with zinc granules are not an appealing surface for algae to grow on. Whenever it rains, the zinc releases ions into the water, and these ions prevent algae growth. Zinc-infused shingles look just like regular shingles, though they generally cost a little more.
Make sure the roofers use synthetic underlayment.
Your roofing company will put a layer of some material under the shingles. Usually, they will use tar paper. However, on a roof shaded by a tree, you want to make sure that they use a synthetic, waterproof underlayment material instead. This way, if a little water works its way through the shingles (especially later on when they're aged) there will be an extra layer of protection to keep it from leaking into the home.
