Polyurethane roof coatings are like a strong shield for your roof. They are good at protecting roofs from getting worn out. Think of them as a tough layer that keeps your roof safe for up to ten years.

Polyurethane comes in two main types: aromatic and aliphatic.:

• Aromatic polyurethane is cheaper but doesn’t stay looking good as long.
• Aliphatic polyurethane costs a bit more but keeps its color and fights off sun damage better.

These coatings are great because they’re super strong. They can handle a lot of wear and tear, which means they’re excellent at keeping your roof in good shape for longer. They’re good at sticking to your roof so they won’t peel or crack easily.

Applying polyurethane coating is something usually best left to professionals. It must be done carefully to ensure it covers evenly and works as it should. Once it’s on, it forms a durable layer that helps your roof withstand bad weather and sun, keeping your home safer and more comfortable.
