- Leaky Chimney Flashing
- Leaky wall flashing at low-slope roof
- Mixed attic exhaust ventilation types
Chimney leaks were evident by cement repairs to the counter flashing. Some of the flashing even had rust areas and there signs of an old shingle repair.
Mixed attic exhaust systems may cause more harm then good. The problem here is that when the electric attic fan is activated (by a thermostat), its very likely it will draw fresh air FROM the off ridge vent. This is an example of two different types of attic exhaust. The solution is to omit both types of exhaust and install a continuous ridge vent. No more electric motors to go bad. No more electricity used to vent the attic space. Ridge vents are of the static type. This just means they do not require electric and function all the time.
The low-slope roof portion on the back of the home had been plagued of roof leaks. The current roof was replaced only about ten years previously. The wall flashing that was installed was mounted to the outside of the 2nd story siding. Caulk was the only protection to keep water away. Additionally there were also two vents located at the roof surface level. A dryer vent and a kitchen stove exhaust vent. These posed a challenge since they were in the lowest part of the low-slope area (at the angle change).
You can see where the previous roof installation face mounted sheet metal to the siding to cover over some wood rot.
Both the dryer and stove exhaust outlets were relocated to avoid a repeated roof leak issue.
A true “2-ply” Certainteed low slope system. This consists of a self-adhered base sheet (1st ply) followed by a granulated cap sheet (2nd ply). Both layers turn up the wall (angle change) and new siding will be installed. This ensures that water cannot get behind the roof system like before. No more relying on caulks or sealants to keep the water out. Notice that the wall section is comprised of a continuous sheet with no seams?
