I've watched several of your videos and not only are you doing other people a service you're also doing yourself a service. Good advice for DIYers and still 99% of people are not going to or can get on their roof so at least they can honestly see what you are doing work-wise. It's a win for everyone. And even DIYers like myself that are getting old, I don't want to do it, I just want to know I have an honest person up there that knows what they're doing. So I applaud you!
Do you have any videos that would show how to properly flash an awning attached to vinyl siding? Should I cut the siding and put a j-channel?
Very descriptive here, love it. Great job on the vids.
I've never watched a bad video from you.. You certainly learned your craft,,
What about the gap between the bottom wall flashing and the side wall flashing?
I'm going to be redoing flashing & siding around 2 dormers soon, so thanks for this tip set.
This guy needs to teach in a classroom ! Thanks!
"Functionality trumps cosmetics" !! More people need to think this way!!
One of my big pet peeves when I used to do residential work, was that people would always choose form over function, and I'm not wired that way, I want it to work well, and if it looks plain, so be it
@@IamthathillbillyWas going to be my comment as well.
Man this was excellent. Helped tremendously. Thank you 🙏🏼
I enjoy listening to your expertise…
You’re the best in the game bro
I have the same problems. Thanks for the info!
" Hey Rocky ! Watch me do this stop leak with one hand tied behind my phone " tHanks for the video!!!
People screw up flashing all the time and it's the most crucial thing to get right. Step flashing is the easiest part and yet guys manage to do it wrong quite often. I was surprised that these hacks didn't nail through the bottom of the step flashing.
Thanks for sharing, great job!
Those shingles were a nightmare on our low pitch roofs in Florida when they came out..
Still wrong; 2:05...The front wall flashing should extend past the return wall, then use the extra to wrap around and up the return wall, then the first step flash lays over top of the front wall flashing extension...Let the side step flash come at least 3 inches onto the front wall extended piece. Mark the back of the step flashing against the front wall cut it flush...BOOM-- NEVER LEAK...
You should be extending that base flashing out about 4 inches too..
To the left, correct?
@ correct, both sides of the dormer or anywhere where the base flashing meets the tins. Dormers, walls, etc..
You left a gap in the roof between your new piece of step flashing and the original piece that was short.
Notch the flashing front piece, and lay over that with a notched step flashing piece, then fill the hole in the corner with black jack. It’s the only way unless you’re using malleable copper or tin
Can you make a video on where to nail on the offset/layouts
Awesome vids! Keep it up!
I like that but are you worried at all that the bottom headwall flashing just butting up to that inserted piece will leak right there? Should one calk those two or...bend a small upward angle on the left end of that long flashing just a smidge to keep water from leaking down between the two?
So many hacks out there. I had a client with a stained ceiling. I got on the roof and saw that the roofer literally had 100+ nails heads exposed all over the roof. They didnt nail on the nail line but on the lower exposed part of the shingle randomly. The nail heads were rusted so you couldnt see them easily with her brownish colored roof.
My moms roof was done and they left 12" of flashing missing from the peak area where wall met roof. Pathetic that people literally dont do their jobs correctly.
Her window company missed a caulk joint on one window and it leaked behind the siding an into her bathroom ceiling. HACKs keep me in business fixing their shoddy workmanship.
THANX
Good job!!!
Brilliant explanation!
I'd be suspicious of that nail high on the end wall flashing (left dormer), often times missing decking and likely under lying shingles don't get that high either.
Question - slightly off topic but when you install the head wall flashing, one leg of the flashing goes under the siding and the other leg overlaps the shingle directing water downward. Then another run of shingles is installed on top of the flashing to hide the flashing. How is that final row of shingles (that are on top of the headwall flashing) secured? I was wondering b/c if you nail into the shingle and through flashing you are creating a puncture and there will not be another run of shingles to overlap and direct water past the nails. Do they normally just use and adhesive to fasten the shingles on top of the flashing? With sidewall/step flashing its ok to nail into the flashing b/c there's another row of shingle that will overlap the puncture. I've only seen illustrations how headwall flashing and shingles should be laid out but none of them have said how that final row of shingles on top of the flashing should be fastened.
Hello I commented on and old videos so you may not have seen it
I’m just curious about edge protection in the US do you not need it do you just not use it I’d like to know the rules over there thanks
I have a very unique house im about to roof, a low slop roof Barn style, nearly flat roof, The eve lands on the flat roof which extends with a dormer window and racks on the sides. im lost for as how to flash it properly. Any chance I can send you some pictures to ask your advise?
Yes, you can send them to the email listed on the about page. Or you can find us on facebook at grand roofing inc and send them in the messenger there.
Construction workers are some of the worst. They will continue to do shoddy work until you hold them accountable. Issuing a fine to that worker is a good start. People do not care until it hurts their pocketbook.
Be the raindrop.
Where do you go?
😮
Whoever cares about an "ugly" fix in that corner needs to get a life! It's ugly now, not after.
Do you wear gloves ever? ✋🖐
Or use a flash right they should've got a new roof than the siding
How to flash a dormer where ice dams are likely. I live in a cold climate in an old house where it would be impossible to stop ice dams.
ice and water should run up the wall at least 4 inches and should adhere directly on to decking, don’t nail in your seams or the bottoms of your step flashings, get the bigger size 4”x4”x8”step flashings , it all depends on the situation you’re that will dictate how you go about flashing certain points on a roof, this guys videos are always good to learn on since he also gets snow and ice dams in the winter
Roofing can be far more complicated than it appears.
Puny step flashings. Should have been a minimum of 4" on wall and roof.
Come on. Make a proper bottom saddle!
out of copper and solder it..old school!
You can only blame the install but so much. You can tell whoever owns that home is not willing to pay for quality. You get what you pay for. By going with cheap labor and materials they guaranteed future problems
pretty sure you mentioned the L flashing piece and then didn't do it
missing a few steps here
I would take this down
This video should cover that.

Wanders going roofs..
they don’t know what they don’t know.. school please.
1st off that was a band aid fix at best...that entire flashing is a disaster and needs to be redone...now you still have a seam where the side and bottom flashing are...horrible...I can't believe idiots do work like this to begin with....granted that was a band aid fix but Im talking about the idiots who did it original
It's just a piss poor installation. Regardless of the substandard flashing, with a valley that close, we would have slathered that in grace.
I only had to listen for 5 sec. and he is wrong. Didn't finish video after that.
Lol, no he's not
Hahaha. lol. This dude knows what he is doing. Great roofer. Love his videos.
