Everything You Need to Know About Water Proofing & Coating

If the time has come to look into waterproofing and coating your roof, there are a few things you need to know. This method is one of the best ways to extend the life of your metal roof, so it’s important to understand the costs, chemicals, and processes that will go into waterproofing and coating your roof. Replacing an entire roof is a massive investment, but in many cases a simple waterproofing and coating treatment is all that’s needed to fix what’s wrong and stop leaks.

Although metal roofs offer extended quality and durability, they still break down over time. One of the easiest ways to fix a leaky metal roof is to waterproof and coat it with a rubberized urethane sealant. This substance includes a reinforced polyester membrane, works in replacing fasteners, damaged metal, damaged vent boots, and extends the life of the sealants. While this is something you can do on your own, it’s best to hire a professional who is experienced in this process and knows the correct sealants to use.

Considerations when waterproofing and coating a metal roof

During the process of waterproofing and coating a metal roof, one of the most important considerations is to take extreme care during the sealing/waterproofing process. If this part isn’t done correctly, the entire waterproofing process will be a waste of time and money and could actually make things worse rather than better.

For example, if the roof isn’t cleaned properly, the sealant material with stick to the dirt and dust particles that are present instead of adhering to the roof itself. This creates an inadequate seal and will allow the elements to seep in, creating further destruction to the roof’s integrity and ability to hold out against moisture and extreme weather.

Another reason why it’s important to get a professional to do the waterproofing and coating process is that there are some materials on your roof that can be sealed over, while others must be removed or replaced. Knowing which is which can mean all the difference in making sure your roof is properly sealed and protected. Also, the sealant used must be a professional-grade strength to be durable enough to withstand everything the elements will throw its way!

Common areas that need waterproofing and coating treatments

Often the most common area in need of waterproofing treatment on your roof will be the eave, which tends to rust out quickly. This typically happens because the installation was done improperly and water has become trapped below the roof panels. If a fold in the eave insulation isn’t created during installation (called a hem) with closures and caulk tape, the insulation beneath will wick away water and trap it between the metal roof and the strut of the eave.

In the process of waterproofing a roof, much of the insulation and any compromised panels might need to be removed and replaced. In some cases where the rust is in small quantity, a simple patch might be all that’s needed.
