Location of Dryer Vent
- It is recommended to position dryer vent on roof deck directly above location of the dryer or as close as possible for most efficient exhaust of lint.
- Once location is determined cut hole in roof deck (5”x5” hole or 5” round).
- Insert the collar into hole and fasten to roof deck with at least 4 nails.
- Apply roof cement on the side and top flanges of the collar. Completely cover flanges and approximately 2” beyond flanges onto underlayment with 1/4” thick bed of plastic roof cement.
- Attach dryer duct to collar on attic side of roof deck.
Position and secure
- Place vent so that inner collar attaches to the dryer ducting in the attic.
- Install shingles so that the bottom flange on vent covers over the unexposed portion of the shingle.
- Apply an industry approved sealant under the front flange of the vent.
- Using the holes provided on the flanges, fasten side and top flanges securely with minimum 1.25” standard roofing nails.
shingle installation
- Apply roof cement on the side and top flanges. Completely cover flanges and approximately 2” beyond flanges onto the underlayment with 1/4” thick bed of plastic roof cement.
- Install shingles, cut to fit so flanges are completely covered. Press into place to ensure a complete bound of cement to shingles. Fasten shingles with nails as per shingle manufacturer’s instructions. However, do not place any nails within 3” of the body of the vent.
