Leaks and Water Penetration
One of the most common problems with metal roofs is leaks. These are primarily due to inaccurately finished seams, broken flashing, or worn-out sealants. If left untreated, leaks may result in interior water damage and mold growth.
Loose or Missing Fasteners
Thermal expansion and contraction can cause fasteners to loosen over time. Loose or missing fasteners may keep the roof of the structure tight and waterproof during strong winds.
