Your home’s roof drainage system is made up of valleys, ridges and other components that direct the water runoff into the areas that can drain it away safely. While roofs with a steep pitch can easily rely on gravity to catch the water runoff, flat or low-pitch roofs have to use a different kind of drainage system. So, if you’re planning a roof drainage system for your flat roof, be sure to work with professional residential roofing contractors who have the experience necessary to make it happen successfully.
Keep in mind that flat roofs are still sloped, which is hardly noticeable. Professional roofers will know how to build efficient roof drainage systems for flat roofs, and they often use scupper drains in their designs. If you’re planning to use scupper drains for your roof, they’ll be installed with a parapet or a similar type of perimeter barrier that encloses the roofing system. They’re designed to catch the water runoff and drain them into a connecting downspout.
Inner roof drains are also used on flat roofs and are designed with a low section or channel that collects water and goes into a hidden drain connected to an underground drainage system. One benefit you’ll get from this system is that it’s hidden from plain sight, which can be appealing for some homeowners who don’t want their exteriors obstructed by conventional roof drainage systems. Consult with one of your trusted residential and commercial roofing contractors on which type of system is best for your flat roof.
Part of what roofing contractors do to install a proper roof drain is precisely calculating the surface area of the flat roof. Rainfall intensity will also be factored in, as they’ll determine which part of the roof will be served by a separate leader. These can either be scupper drains, drain pipes, or downspouts. They may also need additional information from the gutter manufacturer to determine how many drains will be needed for your roof.
