Roof Insulation: When Thicker Isn’t Always Better

A common misconception is that the thicker the insulation under a metal roof, the better. However, while insulation is crucial, there's a balance to be struck.

Overly Thick Insulation: Installing insulation that's too thick can cause the metal roofing to warp or buckle. It might also lead to installation issues, where the roof fasteners don't securely penetrate the supporting structure, leading to potential leaks or roof failures.

Ideal Thickness: It’s not about the thickest insulation, but the right insulation. The goal is to achieve effective thermal resistance without compromising the integrity of the roof structure.

Other Considerations: The type of insulation material, its reflective properties, and moisture resistance are as vital as thickness.

It's crucial to consult with roofing experts, like us at CBMR, to determine the ideal insulation solution for your metal roof.
