g-tape has his tape to keep the courses straight, but what about the pattern.
even using my gauge i sometimes have a hard time not disturbing the pattern when passing a chimney or tie-in at the top of the valleys, any tricks you can share appreciated , always willing to learn.
not only brick pattern,but also 5 5/8 pattern.
maybe you need to come up with another tape G,
if it sells ill sell you the copyright

Well G-Tape comes in the 5 inch Standard and the 5 5/8 inch Metric.
But to keep the rain lines straight, we will use the notches in the top of the shingles. but the trick is to not lay the shingles the same way every shingle you put down. Don't keep butting up on the same side of the notch. One shingle butt up on the right side of the notch, the next shingle butt up on the left side of the notch. Flip flop the shingles from right to left. That way the rain lines will be perfectly straight too.

in valleys I normally will back shingle with 1 very high fastener and measure it. Im thinking of trying this tape but well been doing it like that for so long. I see so many homes that have capping on the roof area right off a reverse gable's valley it sickens me. Where has the feeling of being proud gone, where has the quality craftsman gone? G-tape send me a link to that tape you sell I would like to read about it some more before i buy it. Qrfl you can also try when passing a chimney start cutting shingles around, i know you will throw away a few but well treally only way i know of doing it and keeping the weep lines in order. PS the comment was not meant to be racist in anyway shape or form. It is one of many problems in this industry. Hope this helps.

Here you go Pride.

It will help to keep the whole roof straight, around dormers, down valleys, around chimneys, you won't have to roof back down anywhere, all the marks are there for you to roof right up and not have any short or stretched courses.
The only rule is to ALWAYS put the mark on TOP of the shingle. If you do that you will always have the perfect exposure.
There is a few pages that shows how to use G-Tape in different roof problem areas.

The Gtape is so self explanatory. With Gtape, you HOPE that the long, tall cut up ones call you so that you can doa better job in less time. Hard to mess things up with it.
I find it hard to mess up an up-and-over (as we call it) anymore.

I'm sorry, but G-Tape looks like newb material. Good idea if you can't roof straight, or consistantly get crap material (IKO Cambridge for one).

CyNiCal, G-Tape is great for the newbys, but it is also great for the experienced roofer. You can have 2,3,4,5 6 guys on the same side of the roof and every single shingle wioll be installed the same. That way the roof will be perfect. If you didn't use G-Tape, and lines, every shingler installs the shingles differently. Some guys stand, some guys kneel, someguys bend over. All of their eyes are looking at the shingle at a different angle and viewing the shingle from each angle will lay that shingle different from the rest. Useing G-Tape will get everybody on the same page.
Also, when you have to go back down a valley or around a dormer, G-Tape will make sure you lay each shingle in the exact place it is going to go, so you have no short or stretched courses. Yes, you could measure and then chalk the lines, but why do all that calculating or measuring when G-Tape has already done all the calculations for you.
So you see, G-Tape will save even the most experienced roofer time.
Also, the bright tape on the edge of the roof will alert the installer of the edge of the roof. I have seen guys so into their work, they have no idea where they are on the roof, and just a bright colored eye catcher is all it takes to warn them of the edge.

THe thing that improved with the use of G tape was consistency between installers. For some reason (like gtape stated) multiple men cannot seem to install the same side of roof accurately. I can, but nobody else seems to be able to.
THe more cut up, the greater the benefit, in my opinion.

I've found no problem keeping the eyelines straight or the vertical runs straight running the shingles straight up the roof. When going up over a valley backing down and then measuring for a 5 inch row on the bottom works best for me.
Bad batches of shingles can however keep my fighting to run the shingles straight.
Some years ago a roof my father and I did together had no notches on the ends of the shingles (3 tabs). The sup. for the builder was called out to look at a few rows to see what he thought. He said run them the house needs shingles! We tried to gap the shingles to make an eyeline but it didn't look the best. The shingles were Sealdon 20's and should have never made it to the lumber yard.

I, too, thought g tape to be a noob tool, until I used it and it made my hard working professional installers faster and more accurate. Try it. It is worth it in terms of the end product and time savings.

Well mistake do happen lets remember we are human. I would have used a chaulk line where the weep lines are and ran them that way. They would have lined up from the bottom. Just a thought doing things by eye is a bad idea. Please no offence just pointing something out. Trying to make you more professional. You seem to know things just trying to help. I just hope you dont talk to cutomers like i have seen you speak here. If you do and change that 10% more your way.

I can totally understand the benefits of G-Tape. But try this situation on for size:
IKO Cambridge 30 and 40 year shingle is the product I am installing in 2 different locations. My biggest problem with this shingle is what I respectively call the "sabertooth". This is where the top laminated part of the shingle is anywhere from 1/16 of an inch upto about 1/4 of an inch off from the bottom part of the shingle. This shingle also has approximately a 1/4 inch nail line.
The problem arises when you install a few bundles of good straight shingles, then you get a sabertooth bundle. If you keep with the rules and apply the shingle to the shadow line of the previous shingle, then your rows get bent out of joint. And if I were to use G-Tape to just make sure the shingle rows were kept straight, you would definately see the nail line and nails of the previously installed shingle.
Ya think G-Tape can help with the ferocious Sabertooth?

The lines you chalk with Gtape are for the top of the shingle.
