    Any roofing expert understands the need for insulation to increase a roof’s performance and lifespan, and to reduce operational costs. Upgrading roof insulation requires expertise and knowledge, such as a building’s thermal needs and which insulation type is needed to support applicable energy codes. Your roof is responsible for close to 35% of the heat loss in your house. Insulating your roof and attic is one of the best renovations to invest in when improving your home efficiency.

    The Benefits of Quality Roof Insulation

    As a homeowner, you will enjoy many benefits from roof insulation. Some of the most important include:

    Saving Costs and Energy

    With proper insulation from a professional, you will save money and energy. Roof insulation helps in retaining the heat or cold in the house when you need to. Energy is retained when you insulate your roof, leading to low energy costs and improved comfort.

    Damage Prevention

    Without a properly insulated roof, the rising heat melts snow on your roof that leads to trapped moisture and ice dams. Gradually, ice dams, moisture, and condensation damage your roof increasing repair costs.


    Roof insulation is an energy-saving investment. When you save energy, you reduce pollution, which will have a positive effect on the environment.

    Two Roof Insulation Solutions

    The two-insulation solution includes cold and warm insulation. Cold insulation is the most affordable that is placed between and over wooden joists, above your home’s top floor ceiling. Conversely, the warm insulation is placed directly under your roof to reduce heat loss and ensure your home does not become excessively cold in winter or hot in summer.

    Options for your Roofing Insulation

    There are three major types of roofing insulation, depending on your insulation needs.

    Blanket Batt and Rolls

    The insulation type is best achieved with fiberglass, even though other versions such as blanket batt and rolls made of mineral wool and cotton also exist. This insulation is affordable and effective since standard blanket and batt per inch of thickness have an average R-value of 3.5.

    Spray Form Insulation

    The purpose of this insulation type is to seal gaps and leaks inside the wall. Liquid polyurethane that is sprayed into the wall cavity hardens and expands, leading to solid foam. Closed foam has a high R-value of approximately R-6.2 per inch of thickness. Consider hiring a professional for installation since it needs more techniques than merely aiming and spraying.

    Rigid Foam Boards and Foam Panels

    Polystyrene is the material used in rigid foam boards and foam panels that effectively insulate ceilings near the top roof floor. This insulation type reduces heat conduction through elements that make up your home structure such as wall studs and wood. Foam boards and panels are the most effective in reducing energy consumption since their R-value is as high as R-6.5 per inch of thickness.

    Despite the type of insulation, your budget, and insulation needs, contact an experienced professional roofer to avoid reducing the R-value through mistakes such as compressing the insulation.
