Figure out the slope of the roof by setting a carpenter s level on the underside of one rafter in the attic. Use measuring tools to find the length and width of the roof from the ground outside. The more peaks valleys skylights and other obstacles the roof has the higher the installation cost will be.

Repeat this on both sides of the roof. Every 5 inches make a new mark until you get to the rop of the roof. Nail it every couple of feet. Expect to spend 1 500 to 3 000 to remove your current roof before installing a replacement.

Measure the vertical distance rise from the 12 inch mark on the level run to the underside of the same rafter.
