COATING TOO THINLY

For a 10-year warranty, 20 mils of coating needs to be applied. If less than 20 mils of coating are applied, then the product may not last the entire 10 years.

COATING TOO THICK

If the coating is applied too thick (more than 20 mils for a 10-year warranty), then it’s simply a shame on the roofing contractor and great for the customer. This roof will perform great for more than 10 years.

MIXING IMPROPERLY

The coatings that are used now are single component, meaning you just pop the drum open, give it a swirl and begin putting the product down. However, older coatings may have multiple components that need to be mixed to perform properly. If not, then the product is not going to perform how it was designed to perform.

APPLYING BEFORE A RAINSTORM

This one depends on the type of elastomeric coating the roofing contractor is applying. If it’s silicone, then it doesn’t matter. Silicone will still perform as it should if it rains slightly after installation. However, if the roofing contractor is applying acrylic or urethane coating, rainfall slightly after installation will damage that coating. Rain can even wash your coating off the roof!

POOR SUBSTRATE PREPARATION

Preparation is King! Just like painting the walls of your home, if your walls are full of dirt or dust, the paint isn’t going to adhere or perform how it should. A roofing contractor needs to clean and dry your existing substrate before application. If this isn’t done, the coating will not adhere properly and will not perform how it was meant to.

A rule of thumb is clean, dry, and sound.The roof should be so clean that if you drop your sandwich, you should still want to eat it.

A very clean roof is important for proper adhesion and performance.
