how to shingle a roof?

Answer 1

You can shingle over two layers of shingles. Place the first row (bottom row) with the tabs pointing up, all following rows are tabs down and 3 to 4 nails per piece. second row starts with full piece, third row starts with 1/2 piece, then repeat.

Answer 2

The easiest shingle job you can do without having to do anything to figure out if you want to lay the roof out in quarters halves ot thirds, is to buy Architectural shingals.
Install the tin drip edge. Start at the bottom, put down a roll of ice and water sheild. (comes in rolls about 3 ft wide) then tat paper the rest of the roof with about a foot overlap. start at the bottom and put one row of shingles on upside down. (If you use arc. shingles take the layers appart)
If you use arc. shingles, put the first row down starting with a full piece. There are three cut sizes and instructions on the bags. Then all you need to do is line up the gussets on the shingles for spacing. No measuring, and no snapping chalk lines. Straight every time.
If you use regular shingles, get help, or get a book. Too much measuring and instruction to do on this site.

Answer 3

start at the bottom edge, turn the first layer upside down with a 3 inch over hang on the edge of the roof, them start putting them right side up over the upside down ones, then stager the tabs, so the groves are NOT in line with the next row, the groves need to be off set on each row,
look on the package it gives instructions

Answer 5
