Why do skylights need a 15 degree pitch?
This is known as ‘deflection’ and means that without pitching the rooflight up slightly at one end, rainwater will accumulate and begin to ‘pond’ on the glass. When this evaporates it can leave unsightly marks and stains behind.
What is the minimum pitch for skylights?
The recommended pitch for skylight installation on a flat roof. For many skylight applications on flat roofs, there should be a minimum pitch or fall of 0.6 in 12. This is enough to ensure that water will drain off the surface of the glass and avoid pooling.
What angle should skylights be?
A general rule of thumb is to add 5 to 15 degrees to your location’s latitude to get the perfect slope for your skylight. Fort Collins is at 40.5° north latitude so the ideal slope would be 45.5° to 55.5° for a south facing installation. Check with an installer to see if an increased angle is necessary.

Are pitch and slope the same?

The International Residential Code (IRC) specifies minimum requirements for roof coverings and mandates the use of the roof-covering manufacturer’s installation instructions.
