TPO flat roofs are popular for commercial buildings because they offer durability, energy efficiency, and low maintenance. However, like any roofing system, they require regular inspection and repair to prevent leaks and damage.
The inspection process for TPO roofs involves checking the membrane, which is the top layer of the roof that protects it from weather and UV rays. It should be free of cracks, tears, punctures, blisters, wrinkles, and loose seams. Any signs of deterioration or damage should be repaired immediately to prevent water infiltration and further damage.
The flashings are the metal or rubber pieces that seal the edges and corners of the roof. They should be securely attached to the roof and the walls and free of rust, corrosion, gaps, and holes. Any signs of wear or damage should be repaired or replaced to prevent leaks and moisture problems.
The drains are the openings that allow water to flow off the roof. They should be clear of debris, dirt, leaves, and other obstructions that could cause clogging and ponding. Any signs of blockage or leakage should be cleared or fixed to prevent water accumulation and damage.
The penetrations are the pipes, vents, skylights, and other objects that protrude through the roof. They should be adequately sealed and flashed to prevent water entry and leakage. Any signs of cracking, peeling, lifting, or separation should be repaired or resealed to avoid leaks and moisture problems.
The types of repairs that might be needed for TPO roofs depend on the extent and severity of the damage.
Patching lets you quickly fix the membrane's tiny holes, tears, cracks, and punctures. It involves applying a compatible patch material over the damaged area and sealing it with an adhesive or heat.
Seaming is repairing loose or separated seams in the membrane. It involves cleaning the seam area, applying a primer and seam tape, and pressing them with a roller or a hot air gun.
Flashing is a technique of repairing or replacing damaged flashings around the edges and corners of the roof. It involves removing the old flashing, applying a new flashing material over the edge or corner, and securing it with fasteners or adhesive.
Resealing is the process of repairing or replacing damaged seals around the penetrations in the roof. It involves removing the old sealant, applying a new sealant around the penetration, and smoothing it with a tool or a finger.
TPO roofs are designed to last decades with proper care and maintenance. Inspecting your roof regularly and repairing any issues promptly can extend its lifespan and performance.
