Trouble in the Valleys: Fixing the Valleys in Your Roof
The valleys are a dangerous place. The valleys are the channels where two sides of a roof meet, so they create a fold —or a valley— that can often trap moisture, leaves, or corrode over time and likely to cause leaks. The truth is that in order to do a valley job right, there is a lot of care and caution that needs to be taken. Not many roofers can take on the challenge and, in fact, they choose not to. So let’s talk about the trouble in the valleys and how A D Roofing can help.
How Troubles Arise
The valleys of a roof are a precarious area. In our experience, 9 out of 10 roof leaks originate in the valleys. Tearing into your valley requires careful considerations and understanding of roofing, roofing materials and process. A haphazard job on a valley will just mean more roofing work a few months down the line. The old valleys were often galvanized metal and those produced a lot of trouble for people that didn’t take good care of their roofs. Valleys in good condition can often become blocked with debri, leaves, or other obstructions. Because they handle a lot of rain and/or snow runoff, they become susceptible to damage and corrosion. This is why maintenance on this part of your roof is equally— if not more —important than the rest of your roof.
Improperly sealed roof valley: There should have an ice and water shield installed to prevent moisture from leaking in.
Old and aging shingles: If the entire roof is older and damaged, fissures and cracks can begin to form.
Bad installation: If a previous installation did not place nails or shingles in the right place they could have inadvertently drawn moisture in.
The Tricky Part
Both tiled roofs and shingle roofs can suffer from bad valleys. When this happens we have to remove the affected area and completely replace everything. The reason many roofing contractors will either walk away from a valley job or wince is that it requires a lot of careful and meticulous work. When replacing a valley, it is necessary to remove the entire affected area and redo it all.
- There has to be a complete removal of the old valley and flashing.
- New flashing is then installed. It has to be properly lined up and fastened.
- Then all shingles need to be replaced and placed properly as well.
- Nails need to be nailed in at the right distance and not too close to the edge.
A new roof valley will extend the life of your roof and protect your property from the rot and molding of a leaky old roof.
