Let’s talk about roof leaks. Many people don't realize that, in most cases, roof leaks don't actually start on a particularly rainy day. They usually start when the weather is hot and sunny — two things that Las Vegas in particular experiences quite a bit of. After it rains, any water left undrained on your roof is usually dried off by the sun, but it can still cause damage to the area in question. As the sun continues to beat down on your roof, the problem area gets worse and worse. Then, the next time a particularly bad storm rolls around (which can be often during monsoon season), you've got a major issue on your hands that you may not have even realized existed in the first place.
