Standard Slope Of Monoslope Roof

Standard sizing calls for a 6 inch wide roof leg and a 4 inch drop leg with a 1 2 inch drip bend at the bottom.

Standard slope of monoslope roof.

The rise will be the elevation change over the 12 inches. The run or the base number is 12 inches. I adjust the angle between the roof and drop legs to match the slope of the roof. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.

I hem the 6 inch edge and the 1 2 inch drip bend to stiffen the flashing and minimize oil canning when it expands. Pitches above 9 12 are very highly angled and are designated steep slope roofs. Keep in mind that the higher the pitch the steeper the roof. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

This new home design is coming soon to pratt homes in tyler and we wanted to give you a sneak peek at what all the buzz is about. Roof slopes between 4 12 and 6 12 are best for minimizing the wind uplift effects in high wind zones. For example a slope of 6 12 means for every 12 inches of horizontal distance the slope of the roof will rise 6 inches vertically. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.

Unlike standard flat roofs this roof has a steeper and more noticeable pitch and creates varying sizes of front wall heights. The most commonly used roof pitches fall in a range between 4 12 and 9 12.
