Commercial Modified Roof Replacement in South Florida
When overlays are no longer viable, a full modified roof replacement restores waterproofing, structural integrity, and long-term performance. CLS Roofing replaces aging modified bitumen roofs with code-compliant systems built for commercial durability.
Modified roof replacement involves removing the existing roofing system and installing a new modified bitumen system from the deck up. This approach is recommended when the roof has reached the end of its service life or no longer meets code requirements.
