Do Flat Roofs Leak More? A Comprehensive Guide to Avoid Water Damage

Flat roofs have a bad reputation for being prone to leaks, but is this really the case? The truth is, while flat roofs can be more susceptible to water damage, it's rarely the fault of the roof itself. In this article, we'll explore the causes of flat roof leaks and how to prevent them. Flat roofs are not designed with a path for water to drain quickly, meaning moisture can accumulate on the surface. This can lead to water damage if debris stays on the roof for a long time and prevents it from flowing through or redirects it to other areas.

To avoid this, make sure you regularly clean your flat roof without pushing dirt down the drains. Flat roofs are also not as good at draining water as sloped roofs, so water can stay on the roof for longer and cause damage. If water remains on a roof for more than 12 hours, it begins to filter through the membrane and wear it down. To protect your roof from water damage, you should use roofing coatings that are specifically designed to be water-resistant.

It's also important to make sure your roof is as airtight as possible, especially if you live in an area that gets a lot of rain. While no roof is immune to leaks, you can take steps to reduce the risk of water damage by repairing small defects with putty and metal roofing mesh.
