I apologize if I don't know the correct terms and I'm sure this has been discussed... I've heard that people say to use only ridge vents OR a fan, but it's been suggested that we get both by a very reputable roofer (one who is premium/elite for Owens Corning). He said that other people will say not to get the fan too b/c it counteracts the vents, but that we might need it for our house since the ridge vents might not be enough and that it might not be 100% effective, but would be about 98% effective...Another roofer said the same thing and that we could turn the fan on if we want to, but maybe we could set it pretty high (like 160 degrees) and if it got really hot that the fan would kick on. One roofer said ridge vents only and another said fan only... They say our roof is a little difficult b/c there are several gables, areas that stick out and not much "peak" (I think it's called...) The house is 2700 sq ft 2 stories, so I don't know how much that is on the roof. There would be about only about 36 feet of ridgevents I think-and that's 3 different peaks... There has been an attic fan (that I guess hasn't worked for the last 6 years we've been here...didn't even know it should have been on), a couple gable vents (only in the front of the house), soffit vents and quite a few (11?) other "vents" in the roof. This obviously didn't work b/c the shingles deteriorated after 12-14 years...
We're really trying to make sure we get good shingles, but also want to make sure that they have the correct ventilation so they'll be valid for the warranty. We're looking at 30 year architectural shingles, so we'd like them to last! We're only looking at roofers that have great ratings on kudzu and premium/elite roofers for owens corning/GAF/Certainteed. Any info would be greatly appreciated!
