I’m willing to bet that you didn’t even know that granular retention was a thing you want in your life, did you? Since you didn’t know, but definitely want it, let me explain so you at least know why.
What is Granular Retention?Granular retention is the concept that the shingles on your roof should hold on to, or retain, the granules that are embedded on them. These granules play a crucial role in the overall roofing system for three main reasons:
- They provide protection to the asphalt layer of the shingles from UV rays.
- They provide fire resistance.
- They provide the aesthetic appearance (color) of the roof.
