    Over the past few years, flat roofs have gained the reputation from some of the most temporary, short-lived, to very durable and secure, depending on the materials used. Flat roofs can last up to 20+ years but their lifespan is a function of the quality of the installation and the material of your choice.

    Understanding Your Price Estimate

    All necessary materials
    Labor expenses
    Costs for tearing off the existing roof
    Disposal fees
    Building permits
    Profit and overhead charges

    If your flat roof area is much smaller and your building is larger than the given rating system, reach out for a custom quote. We can schedule a free site visit and provide a detailed proposal in 48 hours.
