I know this probably a stupid question, but I'm a single mom who needs
to put a roof on an outdoor shed. Roofers wanted $700. I bought all the
supplies for less than $80.
Reading the roofing books I have an idea of how to do this. And my
18-year-old son is going to help.
But, we went work to put out chalk lines and I need help.
I bought an irwin chalk line set at the hardware store. My first
mistake was cutting the line off the hook, not realizing it needed to
be tied there.
Then, I realized the line has no chalk on it. I do have a blue bottle
of chalk. My son found a sliding lid on the chalk reel. He thinks the
chalk should be squirted into this compartment. It makes sense. But I
was hoping someone could confirm. Also, how much do you put in -- when
do you stop.
Yes, I know, a paranoid, duh, question, but when you have no idea....
It doesn't *have* to be there, just makes it easy to hook over a nail
when you are working alone and don't have anyone to hold the end.
Yes, put chalk in the reel. The amount isn't written in stone but you
might as well put in as much as you can but not so much as to make it
difficult to reel/unreel the string. You can always add more.
Thanks so much for the help. It seemed the thing to go, but when you
aren't sure... Anyway, works perfectly now. Guess that means we have to
get to work (just hauling the shingle bundles a hundred yards from the
car and then up to the roof about did me in already this morning,
True, but even pros will run a chalk line now and then on some jobs,
like around dormers. Besides, for the beginner, a chalk line helps to
buld enough confidence to discard it after a few squares are down. And
don't forget the roof jacks and planks and other safety related items.
1. Based on the price she paid for the supplies (unless she got a hell of a
deal on some closeouts or something), this is a small shed. Probably not big
enough to need roof jacks and such.
2. Once you tear off the old shingles, and put down new felt, there aren't
any old shingle lines to follow. Roofing is enough of a PITA that you want
to do it as little as possible. And that means a tearoff, no matter what
code says. If you lay the felt carefully, you can use the lines on that. For
a newbie, snapping a line every 3rd course or so isn't a bad idea, and only
takes a few minutes. Nothing screams 'amatuer' more loudly than courses that
wander up and down.
I agree with the last statement. Everything
depends on getting the starter course straight,
and the usually means just following the edge of
roof. After that you just need to be careful. In
most cases just carefully butting each shingle to
the next will result in a straight line. But to
insure parallel courses you can use a stick cut to
the length of the shingle exposure and use that to
measure the exposure at each end of the shingle
Yes, that's a very physically demanding job. You've got my respect.
Can you hire any teenage boys to help? They are the ones with energy.
Sometimes no direction, but lots of energy.
Years ago, a friend showed me that on the long flat edge of the
shingle is a cut. You find that cut, and that's where the short edge
of the next shingle lines up.

You can\'t shout down a troll.
That depends on the type of shingles being used. Three-tabs and "shangles"
(those three-tab shingles designed to look like shakes) it is important to
line the shingles up correctly so that the cutouts line up every other row.
On architectural/dimensional shingles, it doesn't really matter.
Actually, shingle manufactures suggest that the
cutout line up after more than every other row, to
minimize streaks and rain groove wear. I followed
the instruction on the package and mine line up
every third row. Most roofers in my area follow
If you ever attempt a larger roofing job, seriously consider rooftop
delivery of the shingles and tar paper. The savings in medical bills
alone can make it worthwhile.
My 1st roofing job was a reshingling, and since the original shingles
were aligned about perfectly, I didn't have to lay down chaulk lines.
But when reshingling it's important to overlap, or "butt up," the new
shingles correctly over the old ones to minimize the amount of empty
space each shingle spans and therefore the sag. This is why the
instructions say to cut the starter course of shingles to the same
width as the tab exposure rather than simply nail down whole shingles
with the tabs facing upward. If the overlap is done wrong, the new
shingles will develop a bend where they sag.
My 2nd attempt at roofing was over bare plywood decking, and I had to
redo it since I originally laid down only horizontal chaulk lines but
not vertical ones. The alignment looked fine to me while I was on the
roof, but from the ground it was a completely different matter. So
chaulk lines are a good idea.
Why would one ever put down vertical chalk lines?
If the alignment of slots is off, the installer is
cutting the starter shingle for each row
incorrectly. Starters should always be cut at the
slot or midway between slots (unless one is into
some fancy pattern. Anyway, the wrapping on each
bundle gives all the instructions.
It is a shed so there should be no dormers, just a
You get a much nicer look and errors are not as obvious if you use the
shorter offset. Can't recall now if it is 1/4 or 1/3 a tab. Done that
way, the tabs don't line up on every 2nd course. In my opinion, the
mark of an amatuer job is slots lining up straight up the roof.
Not to start a discussion, but I don't see how
vertical chalk lines help one align things
horizontally. Normally one aligns a horizontal
thing with a horizontal line. Don't see what the
difference wider shingles would make either,
unless one put them on top of the originals and
then you just align the new shingles by butting
them up to the lower edge of the original shingles.
Yep. In any case, I prefer to use a shingle hatchet. Well worth the
purchase price even doing just one roof, I just finished 2 sheds and a
2 car garage last summer and never used a chalk line except for the
ridge caps (hip roofs). Slap shingle down, adjust with hatchet twice
to set the exposure ( three times on the course starts for the offset)
nail and done. On a larger roof I would probably do a chalk line up
toward the middle.
Using a chalk line requires a college degree. Go to your local
university and sign up for "Chalk Line Classes".
In two years for the basic degree or 4 years for the advanced degree,
you will be a chalk line expert.
