6inch round duct beng used.
1. 6inch hole in the sheet rock ceiling. (piece of cake .. easy)
2. a hole in the roof directly (about 10 feet) above the ceiling. Roof is 5/8ich plywood with roofing felt with standard 3-tab asphalt shingles. Here a vent has to be installed with damper.
Can anyone provide some tips for the 2nd step to prevent leaking after the vent is installed. Any links to good damper and flashing systems. Any instruction of how to cut the shngles and any overlapping methods for the flashing on the vent. Any glues and caulks?
THis vill be done by a contractor.. he is good but he does not have experience with cutting through the roof and making a vent hole or hanlding shingles. But with enough care and reading I am sure we can do it.
Its hard to find contractors here that will just handle this as oppsed to redoing the wole kitchen.
Any help appreciated!!
