Flat Roof Leak Detection FAQs
What is the major disadvantage of having a flat roof?
The most major disadvantage of having a flat roof is the drainage or lack thereof. Flat roofs do have a slight slope built in to them that drains the water, but it is not nearly as efficiently as a pitched roof. The rainwater tends to remain on your flat roof and form a puddle, which can lead to possible leaks or material damage.
Which problem are green roofs most likely to solve?
Problems which green roofs are most likely to solve include: Providing shade, removing heat from the air, and reducing the temperature of the roof surface and surrounding air. Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect, particularly during the day.
Why do waterproofing membranes fail?
Waterproofing membranes generally fail due to poor Waterproofing Application Technique If the material is not applied correctly, it may not form a proper seal or may not bond adequately to the surface. Additionally, applying too little or too much material can result in an uneven surface or coverage that may compromise the integrity of the waterproofing.
How does electronic roof leak detection work?
Electronic Leak Detection (ELD) is a portable quality control testing procedure designed to locate discontinuities (breaches, holes, seam voids) in waterproofing and roofing membranes. ELD determines the location of the breaches by applying an electrical current to the surface of the exposed membrane.
How often should you reseal a flat roof?
You should reseal a flat roof every five years. It's important to seal flat roofs as a pre-emptive measure instead of waiting for leaks or ponding. Any signs of leakage, ponding, or structural damage indicate your roof needs coating. But even if you don't notice such signs, a flat roof should be sealed every five years to safeguard it from water damage.
