If you're in the market for a new roof, you might have to do a fair amount of research. Roofing materials have advanced significantly in recent years, so there is a good chance that the technologies have changed quite a lot since your existing roof material was installed. Even classic materials like wood have become more advanced in many ways because they have superior tempering techniques, better finishes, and longer lifespans.
One common problem that business owners run into when they live in a humid part of the country is moss that grows under the shingles. Even though moss is really pretty to look at, it can be extremely detrimental to roofing. Why? When moss grows under your shingles, it can cause a host of problems including seeping underneath them and making them lift up. Additionally, moss also contains a lot of water in it, which can be really damaging to your roof as well.
