I have since learned that Cobra vent is also made in a smaller size for smaller cap shingles. Oops.

Awesome, thats the big question regarding GAF offering a 11 1/2" precut ridge cap. I could not find one. Hopefully someone from GAF will see this video and your question to help us out.

@@Therealhomeinspectionauthority Sorry, I guess I wasn't clear. GAF makes Cobra Ridge Vent 3 in two sizes: 11.5" (which fits 12" cap shingles) and 9" (which fits 10" cap shingles). Unfortunately, no retailer in my area carries the 9" Cobra, and I didn't have time to get them shipped, so I had to go with the larger size. The manufacturer of my shingles (Pabco) doesn't make 12" cap shingles, so I ended up getting a different brand of 12" cap shingles. Color match wasn't perfect, but close enough.

You cannot see the top of the cap from the ground so it doesn't matter. But i get your point.

They do make a cap for that size. It's called seal-a-ridge@@Therealhomeinspectionauthority

Thanks for the input, i was not able to find a ridge cap to fit the width. Do you have any information on what stores may carry that? As for the whirly bird its scheduled for removal.

@@Therealhomeinspectionauthority Almost any roofing supplier near you will be able to sell a GAF cap shingle for you. That way you cover the ridge vent with a 12" piece that is made for capping homes. Good luck and keep up the content.

Interesting. So, when using ridge vents, you don't want to have any other separate vents lower on the roof?

@@derek.morrison You have the air intake as low as possible ~ eaves and the exhauset to be as high as possible ~ ridge. But only one source for intake one one option for exhaust unless there is a very good reason then try to place the intakes at similar elevations and the exhausts at similar elevations.

Eliminate the other vent near the ridge. All intake should be at the same elevation (eves) and all exhaust should be at the same elevation (ridge). Other vents lower down will create a vortex and block some of the air from exhausting.

Thanks Ray, Hows the new home?

yes sir, i just did it old school with manual labor!

Great question, when I ordered the ridge vent I was not able to find the Gaf shingles that fit the ridge vent. Another viewer told me the same thing when i first released the video. Thanks for your question. The ones i cut are working just fine.

@@Therealhomeinspectionauthority Glad those hand cut ones are working out. Looks great!

@@kfletcher2005 I was roofing back in the 80's and I have always cut my own ridge cap.

Thank you for your comment, So far my custom ridge cap is working just fine. I was unable to find information on the 12" ridge shingles prior to making the video. Another viewer mentioned the same thing in the past.

Excellent, No Issues at all

Not that i am aware of. No bees yet.

not shown in the video but there is a fabric lining attached to the underside of the vents for that purpose.

its been my experience that this is not uncommon with some roof vents. I guess we need to use a leaf blower in our attics!

Absolutely, A few days later after the heat of the day passed I put my thermal gun facing the ridge vent and the air escaping thru the vent was 10 degrees hotter than the roof.
