What are the components of a Residential Roof in Scarborough, ME

Ever thought about the residential roof over your head, as in really thought about it? If not, maybe it’s time to give it some consideration.

Your roof is the protective element of your home. It also includes insulation that can help make your home more energy efficient for both heating and cooling. Having a good idea of its ins and outs can help you spot problems before they start and strategize for better energy performance.


What are the components of a Residential Roof in Scarborough, METhe first layer of your roof starts on the framework of your house. The slanted boards that the roof will eventually lay on are called trusses.


Over the trusses, something like plywood will be installed. Plywood is a composite board that serves as a useful base for other layers of construction material.


Insulation is applied above the plywood. There are many different types of insulation, typically consisting of fiberglass or foam.


Protecting the insulation is a layer of waterproofing. This sheathing is often made of tar paper or plastic and keeps moisture from getting into the insulation and lower levels of the roof.


Over the waterproofing, planks may be added to attach final roofing materials.


Along the ridgeline of the roof, venting is typically placed to allow for air circulation. This is covered protectively by final roofing materials.

Metal Roofing or Shingles

Whatever your personal preferences are, the exterior roofing materials are added last. These may be aluminum sheets or asphalt shingles.

Solar Panels

Improperly installed panels can cause leaks or damage to roofing components. Making sure that the solar company you work with takes care of your roof during installation will save you headaches down the road.
