How to lay asphalt shingles on a roof.

The first thing you need to do when figuring out how to put shingles on a roof is to determine which type of roofing shingles you need. 3 tab shingles are the most common type of shingle they are typically 36 inches long in total. Asphalt roofing shingles simply rely on the force of gravity to shed water from rain or snow melt. Most asphalt shingles are 3 feet 91 4 centimeters in length.

This will help determine how the shingles will lay on the roof width. Continue laying your shingles horizontally up the roof. Measure the length of a shingle as it lies across the roof. If your roof s width is not an even multiple of the shingle s length you will have a partial piece on one end of each row.

To lay out the design for the shingles begin at the bottom of the roof and place a tape measure inch from the edge of the roof to ensure the shingles overhang the drip edge. Asphalt roofing felt paper and nail it in place using 1 inch galvanized roofing nails. If you hit a stack vent or chimney interlace the shingles with the flashing to allow water to run down the roof.
