What is a roof valley trough?
A roof valley is formed where two roof slopes meet. Water collects in a valley to flow off the roof. Your choice of valley installation method is critical because, when improperly installed, valleys are risks for serious leaks. Essentially, there are three main ways to shingle a roof valley: woven, closed-cut and open.
