Most roofers that do shingles will use a heavy base paper instead of a rubber membrane. In this video you will learn how to fix a leak on a valley. Although professional roofers take great care to properly install roof valleys they can be susceptible to roof leaks. Roof leaks are also very common in the winter when all the snow accumulating on a roof creates a potential for a roof leak to develop especially if a roof valley on your property is not properly flashed.

Roof valley leaks roof valleys are created wherever two roof surfaces intersect to form a shallow v shape. Most roofers that install shingles will not have rubber membranes with them to do such areas. When a shingle from either roof intersects and passes over the metal valley flashing it needs to be cut at an angle. Valley areas are prone to leak due to the lack of using proper materials.

In either situation the leaking roof valley can be fixed by removing affected shingles and structural elements and upgrading your roof s flashing. Roof valleys carry a lot of water. If you find a leak in a metal roof due to water damage you ll need an expert to repair rot so ensure that you call a well respected rooferto do this job.

The reason why the roof valley is such a sensitive area has to do with all the rainwater and or melting snow that accumulates and flows through the valley on its way into the gutters. And damaged flashing is behind most roof leaks.
