I'm a building contractor with over 30 years experience and have shingled hundreds of houses. I ran into something I've never encountered before: a roof that was reshingled about 15 years ago was leaking at about 5 spots at the ridge and it had this type of ridge vent. The roofer neglected to install the Mastic underneath. So what was happening was, rain and dew ran off the caps, made contact with the bottom edge of the ridge vent, and worked its way back under the ridge vent (similar to how a curved gutter helmet pulls rainwater into a gutter.) Once the water made contact with that mesh air filter, it acted as a sponge and through capillary action it pulled the water into the house. When I tore the ridge vent off, that mesh filter was sopping wet. Takeaway lesson: when using this brand of ridge vent, don't skip the step of installing Mastic! $20 worth of Mastic would have prevented a $2500 call-back. As an aside: I always hand nail caps. Too many roofers use the gun, it crushes the cap shingles and restricts air flow.
Love your videos! One correction at 1:02 though. Owens Corning ridge vent is only for pitches up to 20 : 12. You could probably make it work for steeper but the packaging specifies 20 : 12 is the limit.
Does the same ridge cap shingle go on top of the ridge vent and the other spots on the ridge which may not be vented? I heard it's important to use ridge caps instead of cut 3 tab shingles on the ridge vents as well. Why would this be if the ridge vents are plastic and durable?
Thanks & That WAs The BEST Ridge Vents I've Seen & Not One Other Video Showed or Even Talked About Using Mastic AT ALL OR THE End Cap, So You & Owen's Corning Win win ,Cause We Need To Do SOMETHING & This is What I Think Is The Best Way To Go, & ALSO Can It Be Stepped On At All Without Distraction of It , & The Cap Shingles ??? Thank You
Thank you, glad you found it helpful. Generally ridge shouldn’t be stepped on too much. But if you do it’ll be fine, I think the ridge is the problem when stored on not the ridge vent
Not necessarily, venting is a complicated topic as far as placement and quantity. You have to make sure you have a balanced system inflow versus outflow.
Just discovered on a friend mom's roof that the ridge was installed over a second layer of roof. But both roofs are sealed so no air is leaving this roof. Sided over the original side dormer vents. One vent on roof. Disaster
I'm very curious about something having to do with ridge vent over box. My experience is that venting should be 50/50 or 40/60 intake and exhaust in sq inch/foot. Yet I see many roofing jobs running ridge vent the full length of the ridge which would greatly exceed the intake area. Can you clear that up for me? Thanks.
Thanks for making that clear. I'm using GAF and there are easy instructions right on the box so I had to wonder why run the whole ridge. Best of luck to you for being one of the only TH-cam roofers that posts a video and stays with it.
I have that Owens Corning ridge vent on my house, and it SUCKS! Hardly any hot air moves through it. Now my new shingles are losing TONS of granules just 3 years out thanks to the convection oven I have in my attic that’s baking the shingles from the inside. Wish I had my roofers do turtle vents instead.
Do you have appropriate intake vents? at your eaves soffits. If not the ridge vents are completely useless. Venting is a system, if you only have one component of it it is pointless.
@@RoofRepairSpecialist so I had that installed in my new garage last year and currently the temperature outside is 80 F and the inside is showing 125 F is that normal?
100% agree. I got the Ownens Corning corrugated garbage rolls on my roof 5 years ago, and my attic has never been hotter. No air movement. So, now I’m having to get bids to redo the ridge vents with a better quality product with baffles and a higher profile so air can actually move. I’m guessing Owens Corning is selling this crap because they know it will shorten the life of their shingles, and therefor create more sales due to roofs having to be redone more often.
@@RoofRepairSpecialistif you’re a roofer and don’t know about ridge vents with baffles, how are you even in business? Ridge vents with baffles have been around for years! 🤦🏼♂️
That corrugated ridge vent is GARBAGE! If anyone has that crap on their hole, they’re NOT going to have effective air movement. I had that installed on our roof 5 years ago, and am currently getting bids to redo the entire ridge vent system with a system that has baffles and screens and has a high rate of air movement. If your roofer suggests this corrugated garbage, find a new roofer.
It's complete garbage so you need to repair every 5 years and mice will chew through that cheap stuff and you will spend even more money when they wreck your attic. My house is 1958 ranch, all it has was 2 gable vents and small box vent, no ridge vent, no attic fan, no soffits and there was never a problem, no mold or anything that is the way it was designed and that is the way it will stay when I get a new roof. Current roof is 23 years old so maybe in 5 years I get a new one.
Every house is different and every area is different. Some places have mice and rats that chew through flashings. Some places have squirrels that cause problems. Bottom line you need to know what works and doesn’t work in your area.
Now that we've made tutorials on ridge vents, inflow vents, dormers and O'hagins, let me know which one you install the most and why!

Devil is in the details for sure

I’ve seen that type of ridge vent pop up so many times/ roll vent is the way to go
Different than the one we’re using? The issue might have been the length of the nail.
Next time you get supplies look for it been using it for years/ roll vent
Thanks so much! I appreciate you and the channel.
Thanks!

Does the poly mesh get dirty after a while and block the flow of air?
I can’t comment on that, I haven’t seen it happen, however it is possibly a valid concern
Do you have a method for installing over existing double layer roof? The current ridge vent is for looks only
Same concept, just make sure to use long enough nails
So I just had my house reroofed and I noticed they didn’t put the ridge vent back up over my dormers they should’ve probably been replaced right?

Cut through both layers.
@@RoofRepairSpecialist ok
When your ridge is longer than length of the roll do you just butt them up and continue?
Correct
Could you install a ridge vent along with Owens Corning Low Profile Roof Vents?.. or is it one or the other?
I responded to your other comment. Hope it helped.

You are 100%correct and more knowledgeable than 80% of roofers. Venting needs to be well thought out and balanced to be effective.

Air pressure is way to high for your nail guns the nails are sinking below shingle surface.
Correct, I was hoping no one would catch that :)
Eh bleh bleh bleh bleh blah blah.. ridgthe vlent!! HAHAHA
Does this actually let the air out??
It does
@@RoofRepairSpecialist so I had that installed in my new garage last year and currently the temperature outside is 80 F and the inside is showing 125 F is that normal?
Do you have intake vents?
@@RoofRepairSpecialist yes from the soffits
Is your company in the LA / Ventura counties area? If so, then what is the name and contact info?
We are in La county, don’t do Ventura though. 627-869-7663, or you can Google “Roof Repair Specialist “
Do not waste your time on this vent. It is a subpar vent. Install only vents that have a wind baffle on both sides.
What is the purpose of the wind baffle? can you give me a manufacturer you'd like, I'd like to look into it.
Gaf.
Gaf makes a great product for sure but we never had any problems or callbacks with the Owens Corning rolls.

Awesome , detailed Video! Thank you so much, I going to attack it soon.
Good luck. I would love to see pictures of the process, tag me on FB or IG
👏🏼🙌🏼
Thank you
The plastic ridge is better than this one in video
Why
LOL. Ask your structural engineer if he wants you cutting a continuous 3" wide strip out of the plywood roof diaphragm at the ridge.
Wait till you see an intake vent
Tell us you don’t know anything about ridge vents without actually saying you don’t. 🙄
Can't rodents chew through the end caps? Baffled ridge cap is better.
Possible, we have never had that problem though.

I listen to 43 seconds of stupid mansplaining before I left.
lol, I’ll go slower next time
I'm confused. How should he have explained how to do this?
That vent is total crap.
Why?
Is it normal to get moisture/condensation inside on the ridge vent?
No, I have never seen that happen. I have seen leaks happen from improperly installed ridge vents all the time. But not condensation.
Such and amazing video!! Very detailed, it helped me and my friend understand our DIY roofing project more in depth! We love strong informative men!!
Love you back 😉
Chingon compa, Gracias 🎉
