I think you did a good job Dave, i’ve never seen Counter flashing done like that but if it works it works😁
And for future reference if you ever have to do that again, they make mortar in a caulk tube which is so much easier for a small patch jobs like that
I did a flashing on a fireplace in 1976 that went into the mortar joints. It was a new fireplace done by a friend that was a brick mason. It was 5’ wide, 3’ deep and 13’ high. At a 9’ height the roof was basically flat, we made a notch in the mortar joints from 3 sides over the roof and extending out about 6” on each side, past the roof. We had some galvanized ducting, it was a lot stiffer (heavier gauge than what you’re using) and made the shape of a squared C. We folded the end where it went into the mortar into the shape of a V. We checked how it fit and it was ok. When we shaped the corners they were open, so we cut some 12” squares and cut out the corners and soldered them in both corners. We cleaned the roof and washed it a day before and put roofing tar about 7” from the fireplace all around. We then filled the mortar joints with white silicon, put the flashing in place, pushed it in the mortar filled joints and used special mortar flat/square nails to secure. We also nailed (regular 8P nails) flashing to the roof and added some more roofing tar over the nails. I sold the home in 1990 and everything was still good. In the last few years the roof was done, flashing?
PS: Had a new fireplace done in 2004 and saddle was done by a professional carpenter with step flashing and top flashing was in stalled with white painted aluminum trim from a roll. It was formed on a brake. It was the installed on a groove cut into the fireplace about 6” above the saddle in a diagonal cut, by a saw with a diamond cutting wheel. It also went on the sides. When I had my roof done in 2019, the saddle flashing was replaced with a step flashing and a normal interlocking flashing using the old cut in diagonal holes. Everything is fine today, no leaks. The insurance company would not pay for a new flashing, but roofer said it was cheaper and easier to replace than reuse the old flashing. The roof was 16 years old with a lot of hail damage. They tore off the original roof (home built new in 2003) when replacing the roofing.
Dave, I really appreciate the comprehensive job you did with your 3 part series on chimney crickets. Your redundancy of flashing layers is exactly the approach that I would take myself (if) I was even-slightly comfortable at working at heights (which I’m not). I have owned homes with “cut in” step flashing, and that is the best possible way to go in my opinion. My present home’s chimney cricket is flashed via the adhesive bonding method - and I currently have a water leak over my living room fireplace in heavy rains. As I watched your videos, I shuddered to think how many trips up and down that ladder you must have taken…and how much planning, layout, and time that must have taken to execute. Score one point for el-cheapo modern adhesive-bonded chimney flashing. However, as I contemplate having my present roof replaced (with new flashing of my chimney cricket) I sincerely wish that I will be able to locate and hire a guy as conscientious and talented as you obviously are to repair my chimney flashing. Great job! Are you interested in doing the same, on a ranch home in Michigan?
Ha ha! Thanks for the super-flattering comment, Gregory. It is MUCH appreciated! As for finding a good person to do flashing up there, you might want to look for a brick mason instead of a roofer. Someone said (except overseas--where it's commonplace) they're the only ones who do it like this anymore. God bless, Gregory!
Masons stair step counterflashing in the mortar joint. Roofers cut one straight line right thru the brick face to make quick work of counterflashing. The old roofer I was blessed to have show me all his tricks years ago told me that a roofer would never make money spending that much time stair stepping the flashing. He also said a mason would never consider grinding a slot in the face of the brick, and that fortunately, he wasn’t a mason.
That’s a great anecdote. I did see a lot of the brick cutting in my research, but I couldn’t bring myself to cut into the brick either. ... probably because I’m a mason wannabe 😉
A plugging chisel is not a roofing tool 😉
Only a cowboy would grind a straight line through the brick and mortar
Great cricket series ! Thank you for sharing! 👍👍👍
Thank you, and thanks for watching!
Dave, THANK YOU SO MUCH for offering such helpful videos to those of us researching to gain knowledge. …and it should be noted HOW MUCH EXTRA WORK is involved in FILMING the project you are doing, not to mention the arduous task of editing. EXCELLENT presentation, and it makes me want to see what OTHER videos you have created.
Keep up the spectacular sharing (and even with a kind and modest attitude). You just may be a SUPERSTAR! :)
I can't thank you enough for that kind reply! Much appreciated!
I think you got the valleys right.
Higher ridge or steep pitch last regardless if it’s a cricket or not. Typically we match cricket pitch to roof pitch. We also remove the entire mortar in joint, pump joint full of sealant and bed flashing into it. This creates a cut of point for water in the brick. Brick and mortar can also absorb water so it’s never a bad idea to pressure wash entire brick surface and apply a couple coats of clear waterproofer to the surface. Keep up the good work Dave!
Thanks for all the info!
I have always used lead flashing. It looks a lot better functionality wise. It works a lot better as well. And I don't do one singular piece. I do all separate pieces and it always comes out looking great
I think lead looks better too, and wanted to use it, but had trouble finding it where I am. It's rarely if ever used around here. Everyone has painted aluminum flashing.
Have never been a big fan of the jagged angular step flashing. I always feel like it looks better with 90° step ups vs what was done here
Very innovative! Nice work 🙂
Much appreciated!
Great video! I’m curious, what’s the benefit of using mortar in the counter flashing joints over using sealant?
Thanks and good question, Ola. The mortar will last much longer. In fact, the mortar will likely outlast the flashing and shingles, whereas even a "lifetime" sealant will leak and crack before the shingles need replacing.
Not to mention the mortar will look better if you use sealant. It may look out of place considering the rest of the chimney is mortar and brick
Dave - To remove Sharpie marker with ease, use Mr. Clean's magic eraser. (Learned from son's various "art" on household items).
Thanks for your project - unsure if we have the mathematic/algebraic skills to tackle!
Thanks for the tip! ... I'm not much for math either--- I just pretty much guess my way through :-) ... Have a good one!
@@FamilyFriendlyDIY... that's referred to as the "SWAG" method. AKA: Scientific Wild Ass Guess
You cut the valley right because it’s on steeper side
there is an easier way bud. who taught you this? Its very time consuming and it will leak.
With that said you are ambitious.
Good job, especially for a handyman
Well done for your hard work 🏁 May need a proper seal round the edges maybe? I'm sure you can fix this if it leaks.
Thanks! ... so far, so good :-)
thats quite a job to tackle . I would be pulling my hair out if i had to do that .
Have you had to redo this? The step downs on your counterflashing is a huge hole for water to get in. You should step down within the mortar joint.
Nope. Still holding up. And I've had roofers look at my roof recently due to a hails storm, and they said it looked great.
Four days to build a small simple cricket no roofer could afford to take that much time.
Thank you for saying that. It really needed to be said. I've been roofing all my life I'm over 60 my dad taught me everything I know I have invaluable knowledge from a roofer who was 30 years older than me. I do slate , tile , ceder wooden shakes, you name it I've done it. Its the hardest work there is , ask anyone on a job site they all started as roofers and went to easier ways to make a living. The lowest paid roofer should make $ 40-$60 an hour . if you don't think so work outside in 90° heat with 450° tar or in a valley with the cold wind blowing .
Lmao
Nice
Thanks!
Do u love in California

OMG! SMDH! I own a roofing company , next time hire a roofer please. I give you kudos for wanting to DIY but that’s a mess and it will leak, not if it’s when.
Dude I've been a roofer for over 40 years. Leave the roofing to people like me. Its great that you did this video but Its not the way pros do it. And I still can't see it from my house , lol
LMFAO. YOU COULD HAVE USED A REAL ROOFER. A HOUSE is MOST PEOPLE'S BIGGEST INVESTMENT . A PRO SHOULD BE CALLED. Roofing is not a hit or miss profession . You gotta get it right the first time.
I appreciate your comments, Peter. I'm sure you and most other roofers can do this better and faster than me.
@@FamilyFriendlyDIY Ever notice how some professionals chime in with actual advice regarding what was done correctly and how improve on the process that was demonstrated in the video while others cannot contain themselves from jumping at the opportunity to bash a person who has the audacity to venture into their territory? Which type would you want working on your property? Most people search for and view clips like this to learn something. Peter hunts them down so he can castigate the content provider and inform the world that he is an unparalleled roofer. Meanwhile Dave takes the high road.
@@61JWolf Thank you for taking the time to post that supportive comment, James . It is much appreciated! TH-cam has definitely helped thicken my skin. It’s viewers like you who make it worthwhile. :-)
@@61JWolf AMEN, brother! Some people take joy in raining on other people's parade instead of pitching in to assist where they see help is needed.
Yeah it's funny how you get most of the pros saying good work, but some things could have been done neater or more efficiently, then you get the few providing zero input just claiming to hire a pro because it will leak. Why would that leak? The shingles are all over lapped properly and the flashing is solid, if not overkilled imo. Sure a pro could have done it quicker and neater, but for the money saved, who cares that it wasn't done in a day. And it's hidden behind a chimney anyway so the irrelevant imperfections will never be seen.
The funny thing with roofing is there's a lot of pros that are total cons anyway. It's one of those professions where people can get by giving the impression they did good work souly because most people have no clue how it's supposed to be done, and most homeowners are not climbing their roofs to check the work afterwords anyway. Not to mention how hard it is to find good help in the industry. @@61JWolf
