Pooling on flat roofs occurs after heavy rains or when snow melts. It can lead to a costly roof repair when not immediately addressed.
Here’s what happens when you ignore poolin on a flat roof.
Despite its name, flat roofs still require a slight slope for proper drainage and prevent water from collecting on the surface.
Vegetation can begin to grow as a roof with pooling water collects dirt. The water acts as a magnifying glass on the roof, increasing the harmful effects of ultraviolet (UV) rays. It can lead to the early deterioration of a roof membrane, flashing and coatings. Also, it compromises the adhesives used in making field-fabricated single-ply laps, weakening the entire roofing system.
Pooling can also attract insects and cause mold growth. Aside from roofing failure, damage can spread to the other parts of the building.
You can prevent the need for a roof replacement and maintain the validity of your warranty by ensuring proper drainage. Most warranties state that it’s the responsibility of the building owner to maintain positive drainage or not let water stay on the roof for over 48 hours under dry conditions.
Check if the drains are clogged with tree branches or debris. If so, remove them. However, if it’s not the case, it’s best to get in touch with experts. They can diagnose the cause of the problem and repair it before it becomes a major issue.
