Row 7 begins with a full 3 tab shingle.
How to shingle roof three tabs.
The 250 mm 10 length is bent in half so that 125 mm 5 will reach up the wall surface and the other 125 mm 5 will extend onto the roof deck.
Step three measure the roof line.
Cut the necessary number of pieces for the ridge cap from the 3 tab shingles.
Use your chalk and tape measure to mark about 12 inches up on the roof for the first set of shingles.
If the slope is shallow so there s no.
The first full shingle that you lay will need to be laid along the centerline of your roof.
For instance when using metal flashing with shingles with a typical 143 mm 5 5 8 exposure such as traditional 3 tab shingles the size of the flashing will be 250 mm x 200 mm 10 x 8.
Place nails in the three tab shingles about 3 4 inch 1 8 centimeters above the cutouts near where the tab meets the upper part of the shingle.
Step four lay the start row of shingles.
In all use four nails per 3 tab shingle.
As described earlier use a utility knife and straight edge to cut at the slots in the shingle effectively creating three equal sized pieces of ridge cap from one 3 tab shingle.
However make sure that you do not nail into the tar strip.
To prepare the tabs and lay the starter course shorten the first starter shingle by 6 inches or about a half of one tab.
Mark a chalk line from the top to the bottom in the exact middle of the roof.
Begin row 5 with the 1 tab shingle and row 6 with the 1 2 tab shingle.
Place the glue strip at and all along the drip edge and the rake edges as well.
How to do it.
Every 5 inches make a new mark until you get to the rop of the roof.
Align and install the 2 tab shingle aligned with the next 5 inch higher chalk line.
Repeat this on both sides of the roof.
Take enough shingles to create one row across the roof of your house and then cut out the tabs of each of those shingles.
Install a starter strip.
Step two prepare start row of shingles.
If possible have the shingles delivered via a boom directly onto the roof.
They will go in the same location as the nails that went in on the first line.
You will once again need 4 nails whenever you are installing the 3 tab shingles.
Use the chalk line to snap a straight line vertically every 6 inches.
You will shingle over this starter course so the bottom course will be double thickness.
Make sure that the tabs are lining up with the bottom line and that the tabs are facing down.
Complete the row with 3 tab shingles.
