What is the layout order of starting three tab shingles rows?
With the standard 3 foot three tab shingles what is the best order of
courses to stager the joints?
After the starter course I use a full three tab shingles. Then cut 6
inches off the end tab of the next course. At this point is where I am
not sure what to do. Do I cut a full tab off for the number three
course? And use a two full tab section. Then go to a cut down t 6 inch
and a full tab for number 4 course. And then repeat? At course five to
8 and so on?
I have seen where they cut 6" off and I have also seen where they cut
8" and then the next row 4". I think its up to you how you want it to
look. I am sure that you will get more replies on this subject.
That's the approach I use.
Start with a full shingle, cut off 4" on the next row, cut off 8" on the
next row, then start over with a full shingle on the next row.
This gives a slightly less formal "rustic" appearance, but more
importantly, it's better at hiding slight alignment errors between rows
(vertical joints only line up every 3 rows instead of every other row).
nails aren't supposed to hit the tar strip anyway. The tar strip is
for sealing the tabs above to the shingle below. I actually got
spanked once for having nails in the tar strip. But your point is
right. the warranty is worthless. Unless it's some sort of a class
action for a defective batch of shingles, shingle companies just blame
And your assessment of the warranty be worthless is based on what?
Roofers generally ignore the instructions on the shingle package anyway.
They go straight up the roof (no pyramid), then work left and right. At
least the faster roofing subs do. Yes, the warranty is void here. Has
nothing to do with one individual laying shingles on his own roof.
The warranty covers material defects. That's it. (Unless you
purchase the "Golden Pledge" coverage from GAF.) So I guess it's not
worthless--those shingles might be defective, and you might get to
join one of those class actions that you see advertised. But if you
think that if you follow every instruction on a shingle package and if
your roof leaks, the shingle manufacturer is going to come and make it
right, you're dreaming.
Guess I dreamed the composition shingle application on the detached garage I
built. Every detail followed. Wasn't that difficult, or time-consuming.
Why a class action suit on a warranty defect? Mountain out of mole-hill.
Sounds like hearsay and suppostion to me.
Well, that isn't "straight", but doing this requires you to slide
shingles between two other shingles for the next "straight up" column
and that certainly can't be fast and risks damaging the shingle.
And why would your way be better? Please explain your reasoning.
Don't give me the line about it being on the shingle wrapper, because
Owen Corning's instructions show "vertical racking" as the proper
method, (Perhaps they are a bit more up on the way the vast majority
of roofs are laid down in this country) In fact, they recommend
against running shingles across and diagonally.
Well, I read those directions and it does say to NOT run the shingles across and
diagonally up but there are no reasons given. Can anyone give me a reason why
those shingles should not be run across?
