First Row For Roof

These shingles are instrumental in making sure the asphalt shingles are correctly laid out on your roof.

First row for roof.

And while this shortcut did protect the roof deck at shingle joints and cutouts it unfortunately left that first course of shingles unsealed and vulnerable to wind uplift. Set out the first second and all the rest of slates on a pitched roof. Before you can begin setting asphalt shingles on your roof you must install a row of starter shingles. Set the first shingle of the second row back a half tab 6 inches 17 centimeters from the edge of first shingle on the first row and so that the bottom of its tabs just touches the tops of the cutout slots on the shingle below.

The exposure on the first course of slates may be reduced by dropping the chalk line for the top of the second course of slates in order to increase the headlap on the starter course. The height distance up the roof of the starter slate must be at least 3 inches greater than the vertical exposure on the first course of slate. Lay the second row of shingles. This 1 2 tab has to be cut off where it hangs off the left edge of the gable roof.

If these first shingles are not installed correctly there will be problems with the entire set of shingles.
