Commercial properties can vary greatly in building size and style but the vast majority of them have roofs that are flat. When it comes to flat roofs, stormwater drainage can be a challenge as there is no slope from a pitched roof to direct it to the gutters where it can be drained away from the building. Flat-roofed buildings do have a protective membrane to prevent leaks but it doesn’t mean they won’t happen. When water accumulates, it’s heavy and without a way to drain away, it could pose a huge hazard. Even small puddles tend to attract birds and be breeding grounds for pests like mosquitoes and can promote fungal growth.
