First Row For Roof

Complete the second row offset one rafter width from the first then move onto the third row and so on until the last row extends past the peak of the roof.

First row for roof.

If these first shingles are not installed correctly there will be problems with the entire set of shingles. The bottom edge of the starter and first row of shingles was damaged from hurricane harvey going through are area and i wanted to repair to keep from having. 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. 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.

Before you can begin setting asphalt shingles on your roof you must install a row of starter shingles. Set out the first second and all the rest of slates on a pitched roof. 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 sealant on an upside down three tab shingle ends up far too high up the roof to effectively seal the first course of the finished shingles.

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