Roof Closed cut valley leaking - Bad nailing 

Dude, you're by far the best roofer on RU-vid! You share a TON of useful info. All the other roofers on here just ragging on insurance all the time without actually sharing anything useful about roofs. Keep up the great videos and the positive demeanor! It's a breath of fresh air to find videos about roofs that aren't completely centered around hating on the insurance industry. It gets old.

Hey listen...........It's not a "Coke".... or a "Soda"...........It's a damn POP!!! As in, "I'm thirsty....You got any POP?" bahahahahahaha!!! great video!

Best roofing content on RU-vid.

Pop in my area, if someone asked me if I wanted a Coke I'd expect a Coca-Cola. Thanks for the videos! I'm not a roofer, never plan on being one, but ever since I've started watching I look at houses on my drive to work and judge their roofs haha. Keep throwing these videos up!

@Matt Mercia You are spot on, quality content and extremely informational.. Please continue to put out this type of content. Highly underrated.

Thanks for taking the time to make videos packed with important information like this. You explained things in just the right amount of detail, it was to the point, and overall incredibly helpful. I appreciate you sharing your knowledge with us. It is clear you take great pride in your work and have a refreshingly positive attitude. In my experience, attitude accounts for just about everything in this life. It is a telltale difference that sets apart the truly great tradesmen/people from all the merely mediocre ones.

I’m a custom cabinet builder but happened across one of your video… needless to say I’m blown away. Your knowledge is incredible. The troubleshooting videos of finding leaks etc is captivating

I got to go check my valley and see how it looks with those points.

I'm impressed that your young and do a quality job. You strive for perfection. The old timers always try to do quality. Sigh their name to job. Most times that didn't get passed on to future generations. That's why we have crappie and thieving contractors now. Props to you. Wish you were here where I live.

Great informational video you hit all the crucial topics in a matter of 10 mins an absolutely correct in ever matter. Keep up the excellent content

They are usually little things but I think I have always learned something from your videos. Some of this stuff is common sense and a lot of so called roofers don't have any.

amazing video! thank you.

I'm in Arizona and we call Plastic Roof Cement "Bull" and i've heard several other terms depending on what part of the country you're in, so every locale seems to have their own terms for materials and processes, but " a rose is a rose" no matter what you call it. I had problems with roofers not cutting the points off in closed cut valleys, some would "redirect" the water as far as 8 feet perpendicular from the valley center line. We started running "bleeder" shingles parallel and 2" out of the center line of the valley and running the field shingle into the bleeder with a square cut, but the easiest and most bullet proof was to install 24" valley metal, that way you could run both sides of the valley at the same time, that way the slow shingler doing the dormer didn't hold up the fast guy doing the main gable roof. You better be careful with all this good info; homeowners will decide that they can do this stuff themselves 😵‍💫

Very helpful! A lot of good reminders in a few minutes.

You make excellent videos. Thanks for the great content.

Very good content. Everything you mentioned is in the manufacturer's disclaimer. Do it rt the first time

Yes, those points in the valley will cause a leak. Technically you aren’t supposed to even do a Cali valley with laminate. It was meant for only 3 tab but I do it anyways. One point to add about nailing the shingles. If you nail above the nail line the shingle underneath will be missed. If you are 4 nailing each shingle then in the end each shingle will have 8 nails. If not they can fail and are EASY to tear off. The main problem with ridge shingles over ridge vent are that they use the same short nails as the rest of the roof that arent long enough. 2” nails are needed but most coilers only go up to 1 3/4” and dont want to hand nail. Also the ridge nails are commonly over driven and will pop off leaving the nail behind.

Appreciate your advice my roof 10 yrs it's leaking same type of valley and in massachusetts. Lol

Excellent vid Brother I love that you show tricks of the trade Like nails away from shingle edges. Question : I have to do an add-on roof 4ft extended to cover full cement Patio I can tie into my trusses at the roof edge but the roof pitch will bring the new edge to 6.2ft to floor I need a tad more height how will it look professionally to bump the pitch upward at the addition to get to 6.7 inches ? I know it world be a perfect world scenario to cut into the existing roof at proper height to get 8feet but it’s a gambrel roof from Amish country as in a kit

Bravo - good video

Just subscribed. Glad I came across your videos.. It's Junr 2023..

It's POP! But you know what you are talking about on roofs. Our new construction crappy roof job leaked at 12 years. We repaired it and more leaks at 14 years. We had the whole roof replaced.

Rusting nails is going to happen when electro-galvanized nails are used. They have a lifespan of 5 to 10 years. Hot-dipped galvanized nails have a lifespan of 30 to 50 years. It is a mystery to me why roofers usually choose electro-galvanized nails. For my re-roof I specified hot-dipped galvanized nails and I'm fine with the small extra cost.

My back yard is hilly country-style and we are I bedded and surrounded by wind-breaking pine and other trees.so while I don't get a lot of wind, ivslsovdont get a lot of sunlight with all the shade trees either.. Not the best environment but better than living 23 miles from Louisiana Gulf🤔

You almost know what you're talkin about good video

Love your videos.....BTW, when I was a kid we called sodas a "Dope" lol

Thank you Thank you... Great video..

Dude, are you on my roof? You found all the same issues that I found on my roof. At about the age you describe. Overlap Valley instead of tin, too short of nails over ridge vent (not sure why ridge vent is even installed since it is a sealed attic), prevailing wind reversed, nails too close to edge, oops nails not caulked, exposed nails on bottom of penetration venting exposed/not caulked, top row of shingles is lower 8" on one side at peak...everything they could do wrong, they did.

I carry a tube of black tar with me and its for if I nail 1 I dont like I cover it

This is what i can't understand...when you talk about not nailing in key ways... i get the keeping nails low and an inch from edge,so you nail go through laminate,,,but how do you actually nail a shingle with nails spaced so you never end up in a key way area??? the shingle is already nailed when you install the next row on top... you have a video showing the best nail placement ??? thanks

Thanks balls for another good one 👍

On my 12x16 gambrel shed roof, I caulk over the top of every single nail with black Dynaflex 230. Since I am DIY this entire shed, I figure this will keep the nails from rusting and eventually leaking. And it does not take so long to do, but I don't imagine any roof installer doing that. Maybe they could use SS nails. My lower rafter is at 76 degree and 6' 10" long, the upper is 5.5 feet long and 25 degrees. Using Timberline HDZ and nailing between the white lines. I did another shed years ago same roof angle on the lower rafters for my FIL, and no leaks and no shingles falling off like they split at the common bond. I am using 6 nails per shingle. It has seen hot days and fully sealed that tar strip. I also used my hand and hit and pressed it down tight for the tar bond to bond well, and it has. I have seen other video where the shingles were slitting in 2, but have not seen that on GAF for the 2 roofs I did with high slopes, maybe they are better.

We call it dog earing when we cut the back corner do this to all flashings and jacks as well and put some tar or "bull" as additional security.

Great video!

great videos!

I'd redo my own roof with your help ha

Hi Brian, Subscribed, can the nails that are too close to the keyway be waterproofed with Henry's extreme wet patch. Just smear it over the nail using my finger. While I am doing this I plan on sealing the front edge of the shingle down to the shingle underneath it firmly. Ya it'd be only temporary, besides Im not sure exactly where the leak is coming from, but I have a solid hunch. At the edge of the Valley at the bottom, the shingle at the edge is pitching upwards causing water to roll backwards. I am a seasoned stucco guy who engages in leak repair and tear downs of stucco, Im familiar with the terminology. I just finished installing edging along the same side that has the new leak, I had to tie into the valley a little bit where I believe the leak is. Water is dripping in my kitchen. I bought some Henrys wet patch extreme. tomorrow I plan on squirting liberal amounts underneath any shingle areas in the lower part of the valley so as to keep water from rolling back under the shingles above? By the way the reason I think the shingle is pitching up right there may have something to do with there being 3 total layers of shingles on the roof already. Home was built in 1976 and this current roof is going on 9 years old. Ken

Bam bam bam nails the shingle down eyes closed. You ask him about nail placement he says he’s been doing this for 30 years, never had a leak. I do not let any random trades person in my house even if they offered to do it for free. I have zero trust in trades people. Only the ones i know.

Dang in 97 I had my roof replaced when I bought this house by some roofers that were independent. It lasted 24 years and I just had a new company replace It witch took 24 years to degrade.These newer roofers need to be regulated.

You lifted the valley so easily. Would that be normal? I feel like wind could easily blow the shingles up?

Please explain flashing to us stuck on that

Sooo Many poor roofers out there that should not be touching another persons roof.

how far should your nail be from a key way, and how far staggered should your key ways be? thanks

if you got rust issues with the roofing nails, why don't roofers use stainless steel roofing nails in the first place? is it because of just cost issue? i don't get it

Helpful!

WTF is soda you mean pop HAHA -new yorker

Why not chalk and re cut the valley

what is your opinion on the california cut valley?

I can't watch shinglers in my area. I just want to yell at them. Nipping corners is beyond their knowledge. It all starts when they use a garden fork to remove old shingles, followed by hammering down all the nails that stay behind. They have no idea what offset means, or underlayment.

In the south you ask for a coke, then you take whatever they'll give you lmfao

Why don't you go over nail place ment

So, on the ridge cap, don’t come in from both sides and meet in the middle? I see that a lot here in Southern California.

Doesn't look bad for diy but for a professional,,,,,yeah

How many years do you think the labor should be warranty? I’m curious since you mentioned that a lot of the leaks start 5-7 years after the install.

The best way to do a valley is platt or weave yes it can be done with lamanated shingles I've been doing it for 30 years never had any call backs I'm an old school roofer we do it right all most want these days is a paycheck Thompson Roofing

📝 knowledge

Doesn't anyone plat valleys anymore?!

So helpful. I’ve been inspecting roofs for five years now, repairing for two. I always learn something new from your videos. I never knew about snipping the ears of the shingles in the valley. I run into a lot of valley leaks. Any other tips on fixing them? I try to avoid just slapping roof tar on to fix a leak. So I wouldn’t think it would be helpful to use it to seal underneath the valley. What do you think of using tar to seal underneath a leaking valley?

Cut valleys are a terrible way to do a valley . Up north where they get a lot of snow , a weaved valley is best. Down south a Deadman valley is best. The open valley is only works where they get little to no rain. And probably the worst way to do a valley.

You call it coke, some call it sodas, we call them soft drinks.

How many nails is too much, too few!

Hello! How far a nail should by away from keyway?

What is your opinion on no cut valley

What’s your preferred method of doing a valley?

BiggerPockets podcast - are you an aspiring real estate investor?

@Matt Merica Ditto!

Hello Brian my roofer (re-roof) said they use and extra layer of peel and stick in the closed valley. Do I need to ask them to use metal flashing or is this ok ? Also do you recommend hot dipped nails vs electroplated ?

Fuking awesome

Another reason for me to replace my own roof. Cant trust none of these yahoos to do it right

Calling soda "Coke" means you are probably in Texas. It's completely stupid. When someone asks you what kind of "Coke" you want, "Pepsi" should not be a relevant answer. "Coke" is a specific brand of soda. It blows my mind how this makes even a tiny bit of sense to anyone. EDIT: Turns out you are in Indiana. I guess the term has spread far somehow.

You ever see a proper job done by a non-roofer home owner? Think of a You Tube researcher.

i put an addition on a rental house i own and the valleys leaked, i redid both valleys and laid down ice water shield and rolled roofing in the valley then did a closed valley and made sure the nails were far enough away from the middle and it still leaks. I did notice that none of the shingles have sealed down because its winter here in new york, could that be the problem why its leaking?
