What is a Roof Valley?
A valley is the internal angle formed by the intersection of two sloping roof planes running from the eaves to the ridge. Roof valleys allow for water to run off.
You’ll likely hear a roof valley described as is, however you may hear some other context clues to describe where the two slopes, or pitches meet.

Protecting your valley is what matters, especially from water. This becomes even more important for roofs that have complexity. KTM prides itself on having master roofers that are trained to the highest industry standards. A valley is a natural weak point and therefore one that you want to insure is waterproofed properly.
