The key difference between a standard flat roof and an insulated one is the material used. A standard flat roof is typically made of tar and gravel, asphalt, or other low-cost materials; whereas an insulated flat roof will use more advanced insulation methods to boost energy efficiency. The insulation may be in the form of spray foam, fiberglass batting, rigid board insulation, or other solutions that are moisture-resistant and provide thermal resistance.Â
With an insulated flat roof, you'll experience greater savings from heating and cooling costs since your HVAC system won't have to work as hard to maintain a comfortable temperature inside your building all year round. You also avoid damage from wind uplift which can occur with standard roofs due to inadequate sealing against the elements. Ultimately you get better protection from severe weather elements like rain and snow too which could otherwise penetrate through the roofing material over time.
If you're considering installing an insulated flat roof for your home or business building, it's best to consult with a local experienced insured, and licensed residential or commercial roofing contractor first before making any decisions regarding installation type and cost estimates based on what's suitable for your needs specifically.
