Roof slope describes how steep a roof surface is.
Why It Matters
Slope affects how quickly water drains, which materials can be used, and what underlayment or installation details may be required.
Common Problems
Common issues include using shingles where the slope is too low, poor drainage, ice buildup, and not recognizing low-slope sections on otherwise steeper roofs.
Building Codes & Industry Standards
Roof coverings have slope limitations in building codes and manufacturer instructions. Those limits should be followed when selecting materials.
Exterior Echelon Notes
Exterior Echelon reviews roof slope before recommending materials because slope is one of the first things that determines the right roof system.
