Ventilating shed style roofs is fairly easy as long as you abide by the instructions that are put in place to do this. You need to ventilate roof roofs when the roof is over a heated area and when the roof is over an air conditioned area.
The most important issue to me is to check the area of the shed roof for baffled sections under the roof deck. This will let you know if you have the right amount of air flow to allow for proper venting of the roof.
The minimum roof slope is 4:12; the maximum roof slope is 20:12. Cut a 2 "slot in the deck as close to the ridge or the top as possible. Keep slot 6" minimum back from the roof edges to reduce the chance of wind driven rain entering the area. Install your shingles up to the slot; install these shingles, cutting the top course even with the vent slot.
Then, install half width of Cobra exhaust vent, cut the 10-1 / 2 "cobra exhaust vent in half and install over the entire roof width covering the vent slot and the shingles. non-corroding metal flashing that will completely cover the cobra exhaust vent.
Make sure that this extends 1 "past the cobra exhaust vent at the roof edge. This is also a minimum 24 gauge corrosion resistant metal. Cover the metal with counter flashing or siding made from materials that will last as long as the shingles being installed on the roof.
Install the cap shingles. Set the cap shingles over the metal flashing in plastic cement to fully cover the metal flashing. Doing this ensures a stable and firm attachment to the roof. Of course you do not have to use the Cobra brand name exhaust vent system. Every roofer has their own preference of what brand they like to use and what works best for them.
Homeowners all around the country know that their home is probable the most expensive and most treasured investment that they will ever purchase in their lifetime. Getting the best roofer that is in the business and making sure that the roofer they hire to do the work needed on the home's roof will bring years of comfort while at the same time making the house as energy efficient as possible.
