madman_us Posted March 31, 2015 Author Report Share Posted March 31, 2015 I used it when I redid my roof a few years ago.it looks really easy to install....when we bought this houes we got a new roof with it but the roofer just capped it off and the hot air is stuck in the attic during the hot 100-115 degrees summer Quote Link to comment Share on other sites More sharing options...
Poisonfangs85 Posted March 31, 2015 Report Share Posted March 31, 2015 I have used it on a tear off and a very large shed, it seems to do the trick, easy product to use too. Quote Link to comment Share on other sites More sharing options...
NERemodeling Posted March 31, 2015 Report Share Posted March 31, 2015 I just use the original cobra on any roofs i do, works great and is less visible http://www.gaf.com/Roofing/Residential/Products/Roof_Vents/Cobra_Exhaust_Vent Quote Link to comment Share on other sites More sharing options...
DR99 Posted March 31, 2015 Report Share Posted March 31, 2015 The biggest thing is you should get some ventilation up on that roof asap. It's crazy the roofers didn't put anything in when they did the roof. I think when I had my roof redone the said the calculations required me to get 2 more vents' Quote Link to comment Share on other sites More sharing options...
madman_us Posted March 31, 2015 Author Report Share Posted March 31, 2015 yeah thats definitely a must have....i just have to buy some more shingles for the roof that i can cap it off after i installed the ridge vents.right now the roofer used some thicker roof cappings, that might not work with the ridge vent....so i just go with the shingles Quote Link to comment Share on other sites More sharing options...
madman_us Posted March 31, 2015 Author Report Share Posted March 31, 2015 im thinking about the ridge runnerhttp://www.gaf.com/Roofing/Residential/Products/Roof_Vents/Cobra_Ridge_Runner orRigid Vent 3http://www.gaf.com/Roofing/Residential/Products/Roof_Vents/Cobra_Rigid_Vent_3 now i just have to find a supplier where i can buy it....GAF says HomeDepot sells it, but i really cant find that stuff their site....maybe i just have to call the hotline or so Quote Link to comment Share on other sites More sharing options...
NERemodeling Posted March 31, 2015 Report Share Posted March 31, 2015 You really want to use a hip and ridge shingle. http://www.gaf.com/Roofing/Residential/Products/Ridge_Cap_ShinglesI use the Timbertex mostly, they are just 2 layers thick and give better protection and a little nicer look imo, each piece also covers 8" vs 5" for 3 tab.. one bundle covers 20lf. I have also used the Seal-a-ridge which is essentially a 3 tab shingle but is cut to be used as cap and provides more exposure of the cap shingle.. around 6.6" vs about 5" I think each bundle covers 25lf3 tab shingles end up being cut narrower on the exposed section where as cap shingles are full width on the exposed section and narrower where they overlap also you will need to cut the 3 tab shingles where as the cap shingles are perforated so you can just break the pieces apart the same size everytime 1 Quote Link to comment Share on other sites More sharing options...
madman_us Posted March 31, 2015 Author Report Share Posted March 31, 2015 i seen people on youtube just cutting the 3 tab shingles and the install them ontop of the ridge vent.now i just have to find the right brand and color our roofer used here Quote Link to comment Share on other sites More sharing options...
rfwjr Posted April 2, 2015 Report Share Posted April 2, 2015 I had cobra 3 installed when I put on my new roof. But I was replacing ridge vent that was already there. They used the ridge shingles on mine. Quote Link to comment Share on other sites More sharing options...
NERemodeling Posted April 2, 2015 Report Share Posted April 2, 2015 i seen people on youtube just cutting the 3 tab shingles and the install them ontop of the ridge vent.now i just have to find the right brand and color our roofer used hereive seen two dudes kiss on youtube.. doesnt mean im im going to run out and do it! haha ok, so you case is not quite as extreme, lol.. 3 tab shingles will work its just a slightly more ghetto way of doing things. i dont know the price difference between 3 tab and seal-a-ridge off the top of my head but i imagine they are almost the same.. not enough to make a difference. the cap shingles will just make you life a little easier. in the picture the red line represents the incorrect way to cut a 3 tab for a cap shingle. if you cut them there, each next overlapping pieces exposed section will be narrower than the piece you are trying to overlap (not sure if that is clear but bottom line is it will not look right.) you have to make 2 angled cuts per tab (green line) starting at the straight section of the tab just before the radius near the middle of the shingle. this way, the exposed section is wider than the section that will be overlapped.pre made cap shingles are cut opposite of 3 tab and eliminate all that hassle..

madman_us Posted April 2, 2015 Author Report Share Posted April 2, 2015 i just found a picture on the internet which is similar to my ridge shingles...the only difference is color and how they are nailed....my roofer nailed them down where you can see the red arrows.nails are exposed to the weather Quote Link to comment Share on other sites More sharing options...
