Flat Roof vs Sloped Roof: What''s the Difference | DKG Roofing
A sloped roof, also known as a pitched roof, is a type of roof that has a steep incline rather than a horizontal layout like flat roofs. Sloped roofs are designed to quickly shed water and snow, preventing water pooling and potential leaks. The angle of the slope plays a crucial role in determining how effectively water is drained off the roof ...
How to Fit Solar Panels to A Flat Roof (Simple Installation)
When you look at installers mounting solar panels on roofs, they are mostly put on sloped roofs. It makes sense since sloped roofs angled the solar panels, helping them catch some sun. But what about flat roof panels? Can you actually install solar panels on flat ...
