| | | | 3. | Place vent over entire length. |
| | | | 4. | Butt multiple lengths tightly and put end cap at end of each section. |
| | | | 5. | Secure cap shingles and vents at the same time by nailing ridge caps with roofing nails in a common overlapping pattern. Nails should penetrate the wood deck a minimum of 1/2 inch (12.5 mm). Position ridge vent to maintain the pitch of the roof before nailing. |
| |
| | | D. | Off Peak Vent: Install off-peak vents as needed to provide adequate ventilation. |
| | | | 1. | Vent Preparation: Use Rigid Roll Plus and peel StormStop membrane from bottom of 3 inch (76 mm) corrugated air return along the one side of vent. Cut off 3 inch (76 mm) corrugated air return attached to StormStop Membrane. |
| | | | 2. | Slot Preparation: Cut horizontal 3/4 inch (19 mm) slot in the deck for desired ventilation. Leave a minimum of 6 inches (152 mm) uncut on each end of slot. Install felt underlayment per manufacturer's instructions on the deck past cut slot. Trim felt from slot opening. Caulk edges of felt. Install roof shingles per manufacturer's installation instructions, past slot. Caulk the top edge of shingles. Trim shingles from slot opening. |
| | | | 3. | Vent Placement: Install Rigid Roll Plus along the slot opening with the 3 inch (76 mm) corrugated air return 1 inch (25 mm) below the ventilation slot. Tack down the lead edge of the roll through the 3 inch (76 mm) air return. Tack the middle and the other end through air return. Pull membrane tight and caulk, 4-1/2 inches (114 mm) up the deck from slot between the roof deck and the StormStop membrane, for the entire length of slot. Nail through modified plastic cap and StormStop membrane into the deck. Install foam end caps. |
| | | | | a. | Caulk the front edge of Rigid Roll Plus and on top and behind vent. Install felt underlayment on top of Rigid Roll a minimum of 15 inches (381 mm). Lap felt from the vent to ridge. Caulk front edge of felt underlayment. |
| | | | | b. | Cut tabs from shingles. Nail starter course of shingles per manufacturer's installation instructions. Caulk front edge of starter course. |
| | | | | c. | Install a minimum of one course of shingles, lapped on top of starter course, over vent. Nails should penetrate wood deck a minimum of 1/2 inch (12.5 mm). Install remaining shingles per manufacturer's installation instructions. |
| |
| | | E. | Shed or Clerestory Vents: Install shed or clerestory vents as needed to provide adequate ventilation. |
| | | | 1. | Vent Preparation: Use Rigid Roll Plus and peel StormStop membrane from bottom of 3 inch (76 mm) corrugated air return along the one side of vent. Cut off 3 inch (76 mm) corrugated air return attached to StormStop Membrane. |
| | | | 2. | Slot Preparation: Cut horizontal 1 inch (25 mm) slot in deck before the wall, where ventilation is needed. Leave a minimum of 6 inches (152 mm) uncut on each end of slot. Install felt underlayment per manufacturer's instructions on the deck past cut slot. Trim felt from slot opening. Caulk edges of felt. Install roof shingles per manufacturer's installation instructions, past slot. |
| | | | 3. | Vent Placement: Place Ridge Vent Plus along the slot opening with the 3 inch (76 mm) corrugated air return 1 inch (25 mm) below the ventilation slot, also covering the 6 inch (152 mm) minimum uncut on both ends Products with StormStop must have an end cap inserted at the end of each section. Apply sealant to the roof shingles, before installing the vent filling any voids between the bottom of the vent and the surface of the shingle. Use butyl sealant conforming to ASTM C1085; latex sealant conforming to ASTM C834; silicone sealant complying with ASTM C920 or asphalt roofing cement complying with ASTM D4586. |
| | | | 4. | End Cap, Vent and Flashing Installation: Pull apart a precut section of the foam end cap found with the vent. Trim enclosed end caps to fit at each end of the vent. Using a utility knife, make a cut in the StormStop material 1/2 inch (12.5 mm) on the side with the air return, back from the end of the section. Using construction adhesive or sealant, coat both sides of the StormStop membrane where it has been cut back at the end of the vent. Insert the foam end cap with the cut back StormStop material between the foam end cap and the underside of the vent to assure a weather tight seal. Install foam end caps at the end of roof and where Trimline ridge vents are joined together. |
| | | | 5. | Nail lead edge of vent through the 3 inch (76 mm) air return and end cap. Nail the middle and the other end of vent through the 3 inch (76 mm) air return. Pull StormStop membrane is tight up against wall and caulk, 4-1/2 inches (114 mm) up the wall from slot. Secure lead edge of Rigid Roll at lead edge and insert end cap. Pull vent tight and secure at about 10 feet. Pull the rest of the vent tight and secure, inserting the end cap. Multiple lengths of vent can be joined by butting the sections tightly together. Finish nailing the vent along the roof deck and along the wall. Nails should penetrate the wood deck and siding at least 1/2 inch (12.5 mm). Nail every 6 inches (152 mm). |
| | | | 6. | Install metal flashing on top of the Trimline ridge vent, it is important that the vent is protected from UV exposure. See detail Flashing Details for dimensions of Metal Flashing. |
