Roof Restoration Planning
Roof coatings are a cost-effective way to extend the life of a roof, reflecting UV rays and preventing leaks. Common types include **Acrylic** (water-based, cost-effective) and **Silicone** (water-resistant, durable).
Knowing the exact square footage and the porosity of your roof surface is critical to ordering the right amount of material. Under-applying can lead to failure, while over-buying wastes money.
Frequently Asked Questions
How many coats do I need?
Most manufacturers recommend at least two coats (a base coat and a top coat) to ensure uniform coverage and proper membrane thickness (DFT).
What is a "Square" in roofing?
Asking for a "square" of material means you need enough to cover 100 square feet. This calculator outputs total gallons needed based on your square footage.
