I enjoy it more when you are giving some commentary while you're working, as opposed to just watching the work. All the little tips like watch how deep you cut with your knife, watching for nail spots when cutting a shingle out, when to use caulk and what kind of caulk/material to use are really helpfull. More tips the better! Other info that I think would be helpful is a bit more on why your are replacing/repairing what your are working on - what failed, why it failed, what to look for ect. Also how you got the call to the job - tells homeowners what to look for/when they should call a roofer to check something out. I'm a small contractor who came across your channel while searching for some roofing tips for a small repair. Its great finding someone who takes the job seriously, doesn't cut corners and does things right

[@GrandRoofingInc]

Hi Peter, thank you for the feedback! I really appreciate getting feedback, it does give me ideas I have not thought of before thank you! I always want to give valuable info, tips and tricks with this channel. What you just mentioned to me will definitely help me. What kind of contracting do you do?

[@70ixlr86]

The nicest thing about watching at true speed without cuts for myself is, Not feeling as if things are taking to long when I have to do them. Crafting is a form of art. A good craftsman teaches best with the actions they use and explanation as they do them. You Sir , could recite a bedtime story while working, and there would still be worlds of learning to be gleaned from your video's. Slowing down a little and just doing as you do, with the thoughtful notations, is an excellent learning environment. But You are fast and know where your headed. Being able to rewind KZbin is a great workaround.

[@munsters2]

I like the detailed, longer videos. If it gets boring, I can fast forward it myself.

[@robchurchill1368]

Never fast-forward the speed. We watch the work with commentary. Every move you make is educational.

[@stevemazzarella7212]

Make them as long as possible. I can watch all day

[@tuyendang925]

Not a roofer this is amateur for his KZbin talk show 🤔

[@pbsartist]

Complete novice yet brave enough to diy anything! This helped tremendously with fixing a leak around the boot. Thank you!

[@GrandRoofingInc]

Glad it could help, thanks for the feedback!

[@howiefeltersnatch6953]

This detailed video is awesome! The more detail, the better. I haven’t done any roof work since I was fresh out of high school and my brother in law was attempting to teach me how back then. Of course I didn’t pay attention and here I am watching KZbin vids to figure out how to replace my worn out roof jack lol. Thanks again for the vid!

[@dudeson3]

One thing for the DIY person is to outline the area of work in chalk as you remove the shingles/nails. That way, when the job is done, you double check the strips/shingles where you were. Chalk will wash off so there isn't any writing left after the next rain storm.

[@callmedpo]

I love how you explain everything!! Keep your videos long! I’ve learned more from you than people I’ve worked with because you give the “WHY” you explain everything that you’re doing and why you’re doing it that way

[@MaMa-qh4dy]

I do not seal under bottom downside of the flange so that if water does get under flange, it will exit out of the downside edge. If that underside is caulked, the water will get trapped and wick-up and under shingle. Just my 2-cents.

[@emmanuelmeyermeyer1083]

Well said

[@y2knoproblem]

That and the exposed nail heads. Oatey has a video on how to properly install this flashing.

[@mattthoms87]

Hey like your channel, and been doing roofing for about 15 years and hate tar to , except areas that need it or manufacture recommends using like lap seems on liberty peel and stick, and all rake and even edges on the only. But I like that black geoseal u use I use the type of product. Works great! I used to use tar in a tube up until about 3 /4 yrs ago to seal back down shingles I disturbed doing a repair come over boot pipe flashing, and I used it on those three tabs that where loose and a client had a few broken or loose good content👍

[@chadhartsees]

I'm always amazed by how much you have to take out to address one area.

[@spirodavis5623]

Thank you, this video was fantastic and a big help!

[@TheLightBeacon]

Great videos! Question: Why caulk around the bottom three sides, instead of the top three sides for water to flow around? Wouldn't that bottom bead prevent water from freely flowing out if it got trapped under the collar? Or is driving rain a greater risk of going upwards?

[@marklynn3947]

very informative thanks for making the video

[@Aepek]

@Grand Roofing Inc. Hey there thx for the vids, appreciate it. As for vid length; I like the longer vids and if don’t like a section or “slow” etc…ppl can always do that fast forward thing themselves, yeah, takes a few, but also allows others who don’t mind to watch a nice complete long episode…so, kinda like best of both worlds type thing; as never please everyone, imo. Thx again, cheers✌🏻

[@cristodavila3861]

On your drip grove where you have bad nail placement, you could add a strip of flashing underneath to keep water away from the bad nail.

[@Thermohybrid]

Keep them long I like that way.. so I built-up more confidence while watching. Believe or not I function that way😅 I Rather learn than getting screwed by the "handyman"

[@MAGAMAN]

Quality work and great advice on tools. Buy a lifetime tool instead of buying cheap and replacing it 10 times, which costs more in the long run.

I’ve replaced these boots by using a lead boot instead which is more flexible and will slide in a lot of times without having to break a bunch of roofing loose.

I have been checking your show out. I like the information. I have done ruffing but never metal roofing. I have a metal roof on my barn and want to put in some sky lights.

I just finished watching the installation video by the manufacturer for that flashing and they said not to nail the bottom where the nail heads will be exposed to weather.

[@GrandRoofingInc]

If you feel unsafe, that's typically when accidents happen. I'm not saying get these and go up there by any means. But these are the best gripping roofing shoes out there. kzbin.info/www/bejne/m2HcZ3Z3iMmlqLcsi=N0uJbsAt86eyRkDk

[@wadeconney6507]

First, love your videos! I just paid for 4 of those to be replaced. I dont understand why you can’t put something over the gasket and seal it up. What is the benefit ? Seems like an accident waiting to happen. With mike it was just the boot seal that was bad every thing else was solid.

[@Aepek]

Here in FL, when roofs go on, and delivered, buckets (least 2) of tar are delivered too; and are painted, slapped, usually by putty knife or taping knife and smeared over roof etc where “tar” goes to seal everything up. Where your at, what do you guys use, as tar the number 1 here for Florida, fyi, not a fan of tar either

How do you use the stuff on the opposite end of the hammer head? Why is it called a hatchet hammer? Also do you ever have problems with getting fiberglass on your hands?

[@trankt54155]

Thanks for an excellent video bro. With me I would not nail the bottom exposed portion of the pipe vent flashing because it is not going anywhere (being held down from the top with nails and also the PVC pipe). The second you put nails and water flows over, even if you caulk the over the nails well, you are creating a chance for leaks, but that is just me.... What is that sealant you are using? It looks clear and is silicone, right?

[@GrandRoofingInc]

I don't remember what I used in this video but the two primary I use Geocel 2300 clear and Geocel 4500 black. I like to have the bottom nailed, not completely at the bottom up a little ways. I have seen leaks due to win driven rain at the bottom of pipe boots. Thanks for the comment!

[@BrettLister]

Do you caulk / seal the boot around the PVC?

[@MSeroga]

I was a bit nervous when you were cutting the shingle while it was sitting right on the boot, not worried your knife would cut through or slip? :P

[@Shryquill]

9:30 So when the new boot cracks and starts letting water in, it will now collect in the pocket you've made out of sealant? Would it not be better to leave a drainage point under the flashing so any water under there can get out, like how car sills have drainage hole?

[@user-sx6mi3vb9i]

May be wrong here, but I thought you werent supposed to caulk the bottom (lower side) of the pipe boot flange. In case any water made its way in, now theres no way for it to escape. Thoughts?

[@crystalbolt6266]

could i put food grade silicone to help get the boot over? or would that interfere with the chemical composition of the shingle?

1/4 inch grommets are 10 cents, there quite a bit cleaner then throwing 3 hand nails in the face. Oatey's are not meant to be caulked down the side like you were saying around the 16:00 min mark, literally says no caulk right on the flashing

[@GrandRoofingInc]

On the plastic ones yes, not on the aluminum like I installed.

[@garychique1638]

What are you standing on. I saw you move a yellow something
