I am currently in need of a roof... I ahve had roofers out to take a look at my home and have gottne mixed reviews. Some say i need a ridge vent and some say a ridge vent wont work on my roof. How do i know i need or can install a ridge vent on my roof? I have a two sided roof with an attic in the home. I have cathedral seilings leading up to the attic in oart of the house and a my gutter are directly up against the huse on the other potion of the back of the house. In the front i have a soffit over hang with little round vents. Will a ridge vent work on the main troof of the home?
Your ridge vent is the exsaust and soffit and or sheething can be the intake.
for the soffit side, use the ..prop-vents method in conjuntion with the soffit to bring the air past the wall, insulation and or floor,or if you have cielings, all the way up to the ridge vent before installing the cieling. If cieling already exsists,....it`s easyest and less expensive to remove roof sheething while re-roofing and install them.
...for the cathiedral cieling, use the cold vent method. This is useing two pices of plywood with strapping between them to appear like the edge of cardboard. At the bottom ( eaves ) use vented dripedge across the length, ( must not have gutters,or ice in winter will back up into the vented metal.)on top of the previously installed ice and water barrier barrier, then a strip over the metals backedge,(minimum ten inches). You can adjust the face angle of the dripedge on a metal break to fit snug against the edge. the ridgevent goes on last. Make sure the holes are cut back one inch on either side of the ridgepole. If you insist on gutters in cold climates, use heat tape to keep the water flowing down the gutters and downpipes, and deal with occational leaks !!
