It is a constant struggle for facilities managers and owners of commercial buildings to keep their single-ply membrane roofs intact. That is why selecting the appropriate repair coating is essential for protecting your investment and avoiding expensive water damage when cracks start to show.
To help you make the right decision, we’ve created this blog post in order to provide you with all of the information you need to choose and apply the best roof crack repair coatings for single-ply membranes.
What are Single-Ply Membranes, And Why Do They Crack?
Made from flexible synthetic materials like PVC, TPO, and EPDM, single-ply membranes provide a lightweight, waterproof roofing layer that’s easy to install on flat roofing systems. However, over time, these membranes can shrink and lose elasticity, leading to cracks. Extreme temperatures can also cause them to expand and contract, putting stress on seams and flashing, which increases the risk of damage. Without an effective coating, leaks can quickly occur, putting your roofing system at risk.

Types of Roof Crack Repair Coatings
If you are planning on getting roof coatings for your building, here are some of the options that you should look out for. Be aware that some types of coatings are more effective on certain single-ply roofing membranes compared to others.
1. Silicone Coatings
Known for their durability, silicone roof coatings are perfect for flat roofs. They create a flexible, seamless membrane that offers excellent waterproofing and UV protection. These coatings can also handle standing water without breaking down, which makes them ideal for areas with frequent rain or humidity.
2. Acrylic Coatings
Typically water-based, acrylic coatings are commonly used on sloped roofs. They provide good UV protection and are environmentally friendly.
3. Polyurethane Coatings
Tough and flexible, polyurethane coatings offer excellent impact resistance. Available in two different types, they are often used as base and topcoats, making them ideal for roofs exposed to foot traffic and harsh weather.
