Everything You Need to Know About Roof Waterproofing

Roof waterproofing is a great way to add a layer of protection to your roof. Here is everything you need to know about what roof waterproofing is, why it is important, and what materials are needed.


What is Roof Waterproofing?

Roof waterproofing provides added protection to your roof because it prevents water from getting inside of your home. It also prevents leaks that can lead to the walls and supporting beams to start rotting. In fact, poor waterproofing is one of the main causes of roof leaks!

 

It involves applying a special coating over your roof to create a watertight seal, as well as ensuring the supporting structures are in place to keep water out. These barriers are also applied around the seams of the roof since that is where most roof leaks begin. This susceptibility to leaks is due to equipment like metal fasteners and nails that cause gaps throughout the length of the roof. Eaves, valleys, and other vertical structures like chimneys are especially susceptible as well.


Why is it Important to Waterproof Your Roof?

Roof waterproofing is an essential step to protecting your roofs and preventing leaks. This is especially true if you live in a wet or humid climate, which can cause moisture to seep through your roof year-round. While preventing leaks is the primary benefit to weatherproof roofing, it also offers several other benefits. For instance, weatherproofing can prevent water stains from forming on your ceilings and walls. Although this is not necessarily a hazard, they are unsightly, and the stains can be very difficult to remove. Preventing them from happening is the easiest way to maintain the appearance of your home.

 

Waterproofing materials for your roof can also prevent exterior walls from becoming mossy and moldy. If water is allowed to come through your roof, it will run down your walls and encourage mold to grow. Not only does this make your home look neglected, but it can also pose a health risk if mold begins to grow inside your house. Weatherproofing your roof can also help you lower your energy bill! Sealing any holes and leaks in your home blocks out moisture and helps keep the cold – or warm – air from seeping out of your house.


What Materials are Needed to Waterproof Your Roof?

While a protective seal can be used as the outer layer is a finishing touch, it is important that waterproofing is a consideration throughout the entire roof construction. Start with a base sheet, which forms the bottom of the waterproofing layer. This sheet is made of fiberglass, composite reinforcement, and reinforced polyester. This layer is the first one over the decking board that seals the roof foundation and the rafters. Next is the underlayment, which is a water-resistant material that protects your roof from harsh weather. The roof flashing also helps with roof waterproofing, as it diverts water from valleys, hips, and returns that normally accumulate water. When looking at waterproofing materials for your roof you should also include gutters since they also help to divert water away from your home.
