Great video, thanks. I just re-roofed my house, last step is ridge vent, thought I was nearly done. Just discovered my cap shingles are too narrow for the Cobra 3. Why on earth would GAF make this product to not fit standard cap shingles? It's baffling, and very irritating. In my opinion, architectural shingles don't look good as cap shingles. Now I'm considering custom-cutting my cap shingles, ignoring the perforations.
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.
The video was good until the ridge caps. GAF makes a perforated Seal A Ridge that would have worked perfectly. The laminate shingle is not made to be a cap shingle. I hope you dont have issues with the dragons tooth coming off in high winds. I do suggest removing the whirley bird. That can cause your ridge vent to become an intake vent, and it's not designed for that. 9:57
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.
I'm curious why you ended up cutting your own ridge shingle when HD sells the GAF ridge cap shingles that are 11 1/2 - 12 in wide to fit the full width of the cobra ridge vent? Were you not able to find these at your local HD?
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.
@@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.
Great video but get the 12" ridge shingles, they will have the tar strip on them and will do a better job. I've been using this product for years now and I use Owens Corning ridge shingles.
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.
Could GAF include the bug screen filter? Seems a good idea especially after having a yellow jacket nest find it's way in! The Snow Country I believe includes the screen - no nails. Kind of makes one wonder what the mfr is thinking 🤔
I have mine installed back 2021 and I just noticed that the plastic part of the vent being chewed up by squirrels. I probably need to replace all the vents and also install the ridge vent guard. Just want to share the information to those who want to install this kind of vents and have trees nearby that squirrels can make damage easily.
At least Owen Corning Ridge Cat has a glass mesh to keep bugs and leafs out. A breathable mesh. Sure would be nice to get open cell foam very thin roll 12" x100' by
I have monier spanish tile and the ridges are barrel tiles. So who do I use when I slot that ridge. They can just sit over ridge- with a single central nail & will not blow them away- save for a Modesto California Tornado; but I need to seal with strips os something soft to mold the perpendicular flat / ridge roll tiles something breathable also since I can leave it open for all to enter.
I think stainless steel screws would be much better than nails to fasten the ridge vent down. Pests are amazingly strong and persistent at pulling up things.
i have this on my house with a shallow pitch dormer on one side. well the plastic waffles in heat and wind driven rain entered from dormer side. i nailed the hell out of the 15' dormer edge with rubber seal nails but i am thinking of eliminating 1/2 of vent on dormer side and re shingling cap . water caused plenty of damage to ceilings i just don't want to go through this again
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.

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

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

@@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.
You have multiple exhaust vents now which will short circuit and decrease or eliminate any air flow from the soffit.
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.

a year later HD still have no 12" but 10" cap shingle. Yet you should use 12x36" 3-tab shingle as cap shingle. thanks for the video!
yes sir, i just did it old school with manual labor!

How did your home made roof cap shingles work for you?
Excellent, No Issues at all

Supposed to cap the entire width of the vent so that the louvers are not exposed.
I have mine installed back 2021 and I just noticed that the plastic part of the vent being chewed up by squirrels. I probably need to replace all the vents and also install the ridge vent guard. Just want to share the information to those who want to install this kind of vents and have trees nearby that squirrels can make damage easily.
I guess I could just staple in 4" wire window screen across the top ridge slots to keep critters and debris out from my tile roof overlaps
At least Owen Corning Ridge Cat has a glass mesh to keep bugs and leafs out. A breathable mesh. Sure would be nice to get open cell foam very thin roll 12" x100' by
Does that roof vent not require the spongy stuff underneath? A lot of bees and bugs can still get in those little gaps
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.

They can just sit over ridge- with a single central nail & will not blow them away- save for a Modesto California Tornado; but I need to seal with strips os something soft to mold the perpendicular flat / ridge roll tiles something breathable also since I can leave it open for all to enter.

Dis. Caulk line to ensure it’s installed straight
combination of vent types is a major problem according to the vent and shingle manufacturers.
Would have done well to have placed blade at an angle (Not 90 deg) to open slot more
i have this on my house with a shallow pitch dormer on one side. well the plastic waffles in heat and wind driven rain entered from dormer side. i nailed the hell out of the 15' dormer edge with rubber seal nails but i am thinking of eliminating 1/2 of vent on dormer side and re shingling cap . water caused plenty of damage to ceilings i just don't want to go through this again
wind driven rain can cause any roof to leak, but on a low pitch roof it is a much bigger problem
How many 4 ft pieces in one box? I found it is around $93 per box at local HD but haven't found the number of 4 ft pieces per box. Thanks.
After you cut the slots on the roof peak, could you feel any heat coming out of the attic?
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.
I have this on my roof but now small leaves and other debris is getting in my attic GAF offerd no solution.
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!
Too bad no filter unless u get the snow country version of GAF. BUT then those mofos don’t give you the 3” ring shank nails.
