How do you slope a flat roof for drainage.

This solution is perfect for homeowners looking for the easy option for adding slope to a flat roof property. The best way to mitigate the damages of rainfall strong winds snow and falling leaves on flat rooftops is to add a slope on it. A rooftop garden or additional outside living space are the top reasons people choose flat roofs. To put it in perspective the angle of this slope would be around 30 degrees.

The most critical of these issues is the flat roof drainage systems. Most of the time water does run off towards a gutter or drainage system but at a very slow pace compared to your conventional sloped roofs with pitches of around 4 12. This means that the rise of the slope goes up or down 8 inches for every 12 inches. To design a sloped or flat roof drainage system we need to know the anticipated maximum rainfall rate and the flat or projected roof area.

The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. Along with the benefits of a flat roof come unique challenges. An example for a steep sloped roof is 8 12.
