12 wrz 2023 · How to Find the R-Value of a Roof. To calculate the total roof R-value, find the total thickness in inches of each type of insulating material within the roof system. For each different material, multiply the thickness in inches by the standard R-value per inch for that material.
The R-Value formula is the measure of a material’s ability to resist heat flow. The higher the R-Value, the better the insulation. This is because it means that the material can better resist heat flow, keeping your home warmer in the winter and cooler in the summer. The formula is:
