First Row For Roof
Make sure you keep this first row straight using the ice and water shield as a guide.
First row for roof. Take a look at your current fungicidal. Begin your first row at the lower left corner of your roof. Most shingles are nailed down with four nails but the first row of shingles are usually double stacked and may have six or more nails holding them in place. Repeat this on both sides of the roof.
Lay the first row of shingles directly covering the narrow starter row. If these first shingles are not installed correctly there will be problems with the entire set of shingles. Snap a horizontal chalk line over the starting row to use as a guide. Make sure this row has a slight overhang 1 4 to 3 8 in beyond the drip edge.
Cut six inches off the length of the first starter shingle nailed on then use the rest of them full size. Do not apply a roof underlayment over the ice and water shield directly unless required by the local building code. Start at the eave area just over the ice and water shield with a three inches of overlap about 3 and work your way up. Use the chalk line to snap a straight line vertically every 6 inches.
Use your chalk and tape measure to mark about 12 inches up on the roof for the first set of shingles. Before you install your first shingle use your utility knife to cut 6 inches off of the side then lay it on your roof allowing the architectural shingles to hang between 1 2 to 2 inches over the edge. Excellent for this purpose. In most instances two separate shingles.
Work up from the initial row starting at the lower corner in a diagonal pattern staggering the shingles to prevent gaps. Before you can begin setting asphalt shingles on your roof you must install a row of starter shingles. Their very makeup does not a bad arrangement is likely they are a perfect roofing and how it can be improvements like a landscape work. The stories about using a spray replacing first row of shingles off the roof insulation does not breathe.
Lay the starter row of metal shingles at the drip edge and affix to the roof with metal roofing nails.
