main advantages. It protects roofs against weather-related
damage as well as sun exposure.

The building remains cooler.
This is because reflective coatings act as energy-saving solutions.
⦁ Reduces Repairs:
Thorough seal procedures help organizations prevent high
maintenance costs.
Steps to Seal a Flat Roof
The process of flat roof sealing follows a systematic approach.
Here’s how to do it:
1. Inspect the Roof
A thorough examination of the roof should happen before
sealing to identify damage cracks and leaks. Address all

The various window and roof sealing materials cater to specific
requirements. Here are the main types:
⦁ Acrylic Sealants
provide both UV protection and building temperature reduction.
⦁ Silicone Sealants

for regions with heavy rainfall.
⦁ Bitumen-based sealants
function as a powerful waterproof barrier. It finds everyday
use in commercial roofing applications.
4. Apply Primer
A primer helps the sealant bond with the roof. Spread the product
evenly before it reaches the drying stage.
5. Apply the Sealant
Calculated application of the sealant takes place when using a
roller or brush or sprayer tool.
6. Let It Dry
Sealants need time to cure. The product instructions will guide
you to achieve optimal results.
Types of Commercial Roofing
