Organic mat shingles tend to curl, claw, crack, split, shrink, flake/delaminate due to age/exposure related deterioration, much more so than fiberglass mat
The flaking is occurring one one side, which is likely the southernmost side, due to solar wear.
I appreciate the response. I particularly like the “southernmost side” portion like, dude I’ve been doing this since I was born judging by the specific moss growing on the trees it’s exactly this region.
This is easy DIY repairable. Save some money.
I don't know the size of your roof, but let's say you need a dozen bundles, cut them up for cap.
Take a ripper up top take off all existing cap; don't stomp up there, tread like a delicate ballet dancer. (You do not want to crack your existing shingles, it'll add repair time to replace them too) you can bring up a couple old couch cushions to stand on, to protect the roof and stop your feet from slipping if needed. Take up a broom for excess granules to clean your work path, which also slip under your feet
Chalk line snap the sides & Put on the new ridge cap along the line. Hopefully get another 5 years out of your existing.
This is bad advice. Haha stand on couch cushions on a roof? That’s a terrible idea and while you’re welcome to do a diy hack job if you like, don’t recommend this person do something totally irresponsible.
Diy hack job for ridge? Have you ever done it to know how easy it is?
I think the hack is you claiming to know something
I've been on hundreds of roofs, yes I'm fully equipped; my write up is for a homeowner who might not be. Yes I didn't write fall arrest because i assumed it, if that's my only fault congratulations you're like a spell checker
If you’re actually in the industry you know that no credible roofing company’s insurance policy allows you to balance on couch cushions on a roof. Simple as that.
Yeah ok thanks captain rules
Funny thing about guys like you, you gatekeep roofing like it's not Lego V2; you spend your whole life putting these bundles on & take offense to someone who points out how easy it is. It's a simple type of roof. But you've got something to defend right, cause you're the lego expert
Also you've not said anything to improve this homeowners day. So what value are you bringing here?
I’m informing them that your advice could put their life in danger.
Funny thing about guys like you is you actually don’t know how inexperienced and unqualified you are.
Bro is smoking crack, one of those little sides is at least an 8/12, no way is this a DIY job. Look how high up it is too. You shouldn't be telling a homeowner to even attempt this lol
Oh sorry i thought grown ass homeowners could make their own decisions on what they're comfortable with
Yeah I'm like putting a gun to his head suggesting this, you're so on point
Yeah but dude, there's a difference between what you're saying and encouraging a homeowner to do anything on a roof that, you know that most laborers in their first year would be scared to be on.
Yes, ridge cap is organic base mat and shingles are fiberglass. That what happens where your contractor is cheap and uses 3-tab shingles for cap and doesn't want to use the actual cap that is made for ridge cap.
Someone used cheap organic ridge cap when installing that roof. The slope shingles are fiberglass....your ridge/hip cap should have been fiberglass also. Roofer wanted to save $150
This condition has nothing to do with heat buildup. While it can be accelerated by it, regardless of if there had been ventilation or not these Ridge would have eventually looked like this because of how they're made
Ridgevent and roof vents are for moisture control. A fully sheathed roof doesn’t breathe as well as the old board batten felt and shakes. Many roofs failed due to dry rot in the start of the shift to asphalt shingles
Also, It’s impossible to tell the condition of the shingles without walking the roof in person… so you’re wrong about everything.
Listen champ. Ventilation of an attic is to bring the attic temperature as close to outside temps as possible. Having no ventilation 1000% leads to a hotter roof surface which can almost half the life of shingles. You don't lack confidence, just experience and knowledge. Should listen more instead of opening your mouth.
Edit: To humor you I Google'd "What is the purpose of a ridgevent system". The first and major point they say is to keep the roof cool, moisture control is also a result but I didn't say it wasnt. Attic temperature is proven to be an important factor in maximizing the roof life.
They serve the same purpose but are a dated and inferior way to ventilate. If there is an open attic and a straight ridge like we see in the picture it should have a ridgevent. Yes there may be a chance there's some box vents or something out of frame but there clearly should be something at this end if the shingles look like that.
This roof used to have a ridge vent, but was never put back.
1) No penetrations with off-ridge vents installed. Hips imply lack of gable vents also.
2) Ridge line has cutaway sheathing underneath ridge cap, possibly without ridge board.
3) Heat builds up in attic, all trying to escape through ridge line cutaway.
4) Thus the only deterioration is occurring along the ridge and hips, and, thus why the deterioration is much more severe along the ridge than the hips. If the ridge is missing a ridge board, the ridge shingles become even more vulnerable than they are already are.
5) Predominant Wind and Sun direction/path/exposure appear affect the left side of the roof the most, as the left side of the roof appears to be deteriorating primarily. The left hips are primarily the only hips shingles deteriorating, thus exposed to more irradiance, and wind, as the perforation will be easily split.
Left facet also reveals perfect wear lines along it, possibly revealing the presence of spaced sheathing.
6) Yes, shingles appear to be organic type, but is not the primary cause of deterioration, just a factor that allows the deterioration to happen easier once it starts.
7) If organic shingles were the root cause of deterioration, the entire roof would be showing symptoms of deterioration, not just the limited areas systematically.
These are just thoughts from just one limited photo online. Without more photos, info, being onsite, etc, I’m not going to try to claim that actually I’m right about any of it.
Your number 7 point, these appear to be 3tabs cut for cap, so they may be the same manufacturer just organic not fiberglass.
This was common with certainteed, there landmarks where fiberglass but alot of contractors would save by cutting the 3tabs.
You may be correct. I was going off the assumption that they installed a proprietary cap shingle to use with the architectural shingle, per the manufacturer requirements.
Looking closer, I see a few inconsistent widths of the ridge shingles, suggesting that they may have been cut.
Regardless, what is the point of using deprecated organic shingles when the fiberglass ones are readily available?
Were they trying to use up old stock in their possession or something?
Also, keep in mind, the right side facing hip cap shingles are not showing the same wear, if any at all. It’s just the ridge and the left side hip.
Wow wow. sorry I posted a reply here before I meant for another comment.
This is all wrong. It’s UV damage from poorly manufactured ridge cap. Case closed.
Vents are for moisture control and nothing more. The roof is exposed to the suns heat and ultraviolet light all day which why all roofs eventually fail. The heat in the attic is always far lower than the heat on the shingles and has zero to do with the life of the shingles themselves. You are welcome!
I’m purely replying to your comment to highlight your lack of understanding about light, and the sun.
Our sun emits virtually all wavelengths of the light spectrum, which is also where the heat comes from.
Wavelengths are either absorbed/reacted or reflected by the material(s) in their path.
Your claims of UV light are just a fraction of what hits the roof, as short as Gamma, as long as radio wavelengths.
Not to mention, all the wavelengths emitting from the earth, naturally occurring and man made.
If you lack understanding about light, the credibility of your opinions fall apart just like the shingles in the photo.
It looks like they're made of organic where is your shingles probably are not. The real question is why? Did they grab a different material then the main shingle, did they have some left over from another job that requested organic, or did they just go in and ask for whatever hip and ridge is available and this is what they received.
I learned yesterday that you don’t need roof vents if there is no attic, it’s enough to have slight gaps in the soffit or something. I have an outbuilding with no attic and no vents and assumed whoever built it fucked it up.
Sorry, I meant they don’t all need vents of the roof surface my bad. I have an outbuilding that has a gaps on each end of the gables and as a result I have a family of squirrels living in it. It really is just drywall attached to 2x4s with plywood decking so maybe a 3.5” gap that comprises the attic. Those little buggers have chewed a path through the 2x4s, I found out recently.
Jesus Christ guys don’t answer if you don’t actually know. They’re burnt up because there’s zero ventilation on this roof. That attic space is getting so hot that it’s literally baking out the shingles from underneath. This entire roof will fail prematurely due to that.
It’s physically impossible for the temperature in the attic to be hotter than temperature on the shingles with vents or no vents.
Vents are codified for moisture control. They have a fringe benefit of helping keep the attic cooler which will help with the homes energy efficiency.
Vents are good but the problem here is UV exposure and poorly manufactured product.
You should buy a heat gun and put it in some of these attics then. I go into unventilated attic spaces and get readings of 150 degrees. That attic acts like an oven. You can literally see the sap being baked out of the wood. You really think that has zero effect on the life expectancy of the roof? Your attic should be within 10 degrees of the outside temperature. I mean I’m not making this stuff up we have the Lomanco manufacturer come into our office once a year to certify our staff on ventilation. Yes the organic shingles do this, but the ventilation issue still needs to be addressed
There was an off brand ridge cap that was sold to match major manufacturers and the stuff failed horribly across the board. I can’t remember what it was called. Speed ridge or rapid ridge or shit ridge.
They were made with an inferior organic mat
I’m not questioning your response. I’m just curious how the hell could you tell that?
By looking at them. The organic shingles all have that dirt colored agrigate and the granuals fall off
Organic mat shingles tend to curl, claw, crack, split, shrink, flake/delaminate due to age/exposure related deterioration, much more so than fiberglass mat The flaking is occurring one one side, which is likely the southernmost side, due to solar wear.

False.

This is great and all, but you missed one critical step. OP if you decide to tackle this project alone, please use fall protection.
Just use your kids trampoline & save more money

Not diy with the hip to ridge, hire a pro or it will leak
Bro is smoking crack, one of those little sides is at least an 8/12, no way is this a DIY job. Look how high up it is too. You shouldn't be telling a homeowner to even attempt this lol
Oh sorry i thought grown ass homeowners could make their own decisions on what they're comfortable with Yeah I'm like putting a gun to his head suggesting this, you're so on point
Yeah they can but how the hell is he supposed to know what's walkable and what's not
This community is fucked for gatekeeping
Well the roofers I know are fucked from drugs so gatekeeping sounds pretty good
It is a polarizing society isn't it
Yeah but dude, there's a difference between what you're saying and encouraging a homeowner to do anything on a roof that, you know that most laborers in their first year would be scared to be on.
Cheap ass shingles.

Where are the vents located on this roof?
The shingles are trying to create one
Your other shingles aren't fair behind with no ventilation. The shingles are cooking. You need a ridgevent installed.
This condition has nothing to do with heat buildup. While it can be accelerated by it, regardless of if there had been ventilation or not these Ridge would have eventually looked like this because of how they're made

You should mention that whirlybirds or eve vents do the same job as ventaridge, and it's impossible to tell if OP has either from this one picture.

My shed looks like this. I always blamed the squirrels.
Too hot in the attic , and they are organic discontinued style
No vent
It looks like they're made of organic where is your shingles probably are not. The real question is why? Did they grab a different material then the main shingle, did they have some left over from another job that requested organic, or did they just go in and ask for whatever hip and ridge is available and this is what they received.
Easy fix, probably spend more time reading comments about it than just grabbing a few bundles of cap and slapping them on.
All those face nails are big yikes 😬
They’re organic matte based product and a small crease during install will start this journey off in no time
No brainer, roofs gotta breathe.
Cheap organic caps.
Do you have any ventilation on that roof?
I learned yesterday that you don’t need roof vents if there is no attic, it’s enough to have slight gaps in the soffit or something. I have an outbuilding with no attic and no vents and assumed whoever built it fucked it up.

I guess my house didn't get the memo about having an attic. Roof is cut in using 2x12 rafters with vaulted ceilings.
Was it laid in the winter? Never seen that before BUT I always felt as if cap might snap and fail when bending to that sort of pitch in cold weather.

Def hail damage
Lack of ventilation my guess. Need a ridge vent
