These specialized products are designed to adhere to metal surfaces and create a protective seal against moisture, ensuring that the roof remains leak-free.

Sealants are typically applied along seams, joints, edges, and any visible cracks or gaps in the metal roof. They act as a flexible barrier that expands and contracts with temperature changes, allowing for the thermal movement of the metal without compromising the seal. By effectively sealing off vulnerable areas, sealants help to prevent water from penetrating the roof and causing structural damage, rot, or mold growth.

The key is to choose high-quality sealants specifically formulated for metal roofs and to follow the manufacturer’s instructions for proper application, drying and curing times. Regular inspection and maintenance of the sealant are also recommended to guarantee its ongoing effectiveness in keeping your metal roof leak-free.

Process for identifying leaky spots in your metal roof

• Visual inspection: Start by visually inspecting your metal roof for any obvious signs of leaks. Look for water stains, discoloration, or mold growth on the ceiling or walls inside your home, as these can indicate the presence of a leak. Trace the source of the stain back to its origin on the roof.
• Check roof penetrations: Inspect areas where roof penetrations occur, such as chimneys, vents, skylights, or pipes. These areas are common sources of leaks. Look for any gaps, cracks, or damaged flashing around these penetrations that may be allowing water to enter.
• Examine seams and joints: Pay close attention to the seams and joints of your metal roof. These areas are prone to developing leaks over time. Inspect the integrity of the seams and check for gaps, separation, or signs of damage. Look for any visible cracks or openings that may need to be sealed.
