Not all metal roof coatings are created equal. Acrylic, silicone, and elastomeric systems perform differently. Here’s how to choose the right one based on your roof’s condition and drainage.

Acrylic is one of the most popular roof coating chemistries for a reason, but it isn't a fit for every roof. Here's where it performs best, where standing water and cold weather can trip it up, and how to tell if your building is a good candidate.

Rust on a metal roof rarely looks urgent, but it will pull a new coating system apart from underneath if it is not dealt with first. A rust-inhibiting primer stops the corrosion and gives the coating a surface it can bond to. Below is a look at when primer is required, how it differs from a rust converter, and what tends to happen on the roofs where the step gets skipped.

Silicone and acrylic roof coatings both work well, but only on the right roof. Drainage, slope, sun exposure, and foot traffic decide which chemistry belongs on your building. Here is how to make that call before you spend a dollar on materials.
