First row for roof. Excellent for this purpose. Use the chalk line to snap a straight line vertically every 6 inches. 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. These shingles are instrumental in making sure the asphalt shingles are correctly laid out on your roof.
Before you can begin setting asphalt shingles on your roof you must install a row of starter shingles. Take a look at your current fungicidal. Repeat this on both sides of the roof. Do not apply a roof underlayment over the ice and water shield directly unless required by the local building code.
Make sure you keep this first row straight using the ice and water shield as a guide. For the first row of shingles called a starter course or strip you cut the tabs off three tab shingles and apply them with the self sealing adhesive strip facing up along the eave. 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. Work up from the initial row starting at the lower corner in a diagonal pattern staggering the shingles to prevent gaps.
If these first shingles are not installed correctly there will be problems with the entire set of shingles. Use your chalk and tape measure to mark about 12 inches up on the roof for the first set of shingles. Lay the starter row of metal shingles at the drip edge and affix to the roof with metal roofing nails. Every 5 inches make a new mark until you get to the rop of the roof.
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. Make sure this row has a slight overhang 1 4 to 3 8 in beyond the drip edge. Lay the first row of shingles directly covering the narrow starter row. In most instances two separate shingles.
Cut six inches off the length of the first starter shingle nailed on then use the rest of them full size.
