What Makes Up an Asphalt Shingle?

Surface - Granulated Layer

This is the portion of the shingle that is visible when the roof is complete.  It provides the color of the roof as well as offers UV protection to the shingle, allowing it to last longer.  This layer can also prevent heat from getting through to the structure of the house, keeping the house cooler.

Asphalt Layer

This is what provides for a waterproof roof, protecting the home from water’s damage.  This is also where most of the weight of the shingle comes from.

Base Layer 

The base is the frame, or, put another way, the part that provides the structure of the shingle.  Most shingles today are fiberglass, and it is the base where you can find the fiberglass. This layer is what holds the whole shingle together.

Adhesive Strip

If you look at a shingle before it is installed, you will see what looks like a dotted line on it.  This is adhesive and it holds the shingle above from rising with the wind.

Nailing Strip

Simply put, this is the area where the shingle must be nailed down. 

Our Shingle Installation Process

  • The first step in installing a new roof is to strip and remove the old roof. This is ideal, as it gives us the ability to inspect the plywood and integrity of the roof underneath. However, in certain cases, we can shingle over the old roof, which can save a little on cost, however in general it is not a good idea. We have ample experience in shingle roof installation for enhancing the external beauty of the house and strengthening its integrity.
  • After stripping off the old roof, we will begin laying underlayment for completing the flat roof replacement process. We begin with laying ice and water shield, a rubberized membrane that is virtually impenetrable to water. We place use ice and water shield 6 feet up from all edges, up and in all valleys, and around all roof vents, chimneys, exhaust pipes, and skylights, to insure a water tight bond with no leaks.
  • The shingles are then layered out in nice, even rows using 6 nails per shingle.
  • On the edge we will install an aluminum drip edge that will insure water will properly run off the roof, and not under the shingles or down your siding. This is very important for ensuring the durability of asphalt roof installations.
  • We will also usually install a ridge vent along the top ridge of the house to insure proper airflow in the attic. This is a very important part of the flat roof installation process. It proves to be of great help for keeping the attic cool, and also to prevent ice dams, which are especially prevalent here in New Hampshire.
  • When we complete the commercial roof replacement process, our goal is to clean up so well you never know we were there! We gather all the scraps, and usually have a dumpster on site. The most important thing is to get up all the nails, and while we get most of them at the time the shingles are removed, the rest are picked up at the end by rolling a special magnet machine over your property, beds, driveway, and grass to pick up all the nails. When we are done you will have one beautiful roof!
