Shingling Started

I'm getting ready to start shingling the roof over the bedroom now. The dark strip you see along the outside edge of the roof is called the eave protection. It's a peel-n-stick membrane similar to what I used to waterproof the basement with. It's applied to the perimeter of the roof to provide protection against the damage caused by ice dams.

Next comes the roofing felt. Roofing felt is made of asphalt-impregnated paper. It comes in different weights, described in pounds... 15# felt, 30# felt, etc. I'm using 30# pound felt. It gets applied directly on top of the sheathing and on top of the eave protection at the perimeter. The felt is just tacked down with a few nails to stop it from moving until you get the shingles applied over it.

Once the felt is down, I can start with the shingles. I'm using Malarkey brand shingles. They are commonly used in this area and I've spoken to a couple of roofers who've recommended them.

Shingles are always installed from the bottom up. Typically you start at the eave and work your way to the peak of the roof. However, I found a very interesting article at that describes a better way of installing shingles on steep roofs like mine.

The shingles are still applied from the bottom up, but you do the roof in sections, starting 2/3 to 3/4 of the way up the roof. You do the top section, then move the roof brackets and walkways down, then do the next section, etc. The biggest advantage is that you don't have to walk on top of the shingles once they are installed. That makes it safer and causes less damage to the shingles.
