  • How do I know if my commercial roof needs to be repaired or replaced?

    The answer depends on the age of the roof, the extent of the damage, and the overall condition of the roofing system. In many cases, isolated leaks or minor damage can be repaired. However, if repairs are becoming frequent or the roof has reached the end of its service life, replacement may be the more cost-effective long-term solution. We can inspect your roof and provide an honest recommendation based on its condition.

  • How long does a commercial roof last?

    The lifespan of a commercial roof varies depending on the roofing system, installation quality, maintenance history, and weather exposure. Many commercial roofing systems can last 20 to 40 years or more when properly maintained.

  • What commercial roofing systems do you work with?

    We work with many of the most common commercial roofing systems found throughout Connecticut, including:


    TPO Roofing Systems

    EPDM Rubber Roofing

    PVC Roofing Membranes

    Modified Bitumen Roofing

    Built-Up Roofing (BUR)

    Commercial Metal Roofing


    Our team can help determine which roofing system is best suited for your property.

  • Which commercial roofing system is best?

    There is no one-size-fits-all answer. The best roofing system depends on your building, budget, maintenance expectations, energy efficiency goals, and long-term ownership plans. During a roof evaluation, we'll discuss your options and recommend a system that aligns with your property's needs.

  • Do you provide free roof inspections?

    Yes. We can inspect your commercial roofing system, identify potential issues, and provide recommendations for repairs, maintenance, coatings, or replacement.

  • What causes commercial roof leaks?

    Commercial roof leaks can occur for many reasons, including:


    Aging roofing materials

    Storm damage

    Open seams

    Damaged flashing

    Ponding water

    Roof penetrations

    Poor drainage

    Lack of maintenance


    A professional inspection can help identify the source of the problem and determine the appropriate solution.

  • Can a roof coating extend the life of my roof?

    In many cases, yes. Roof coatings can restore waterproofing, improve UV protection, and extend the lifespan of an existing roofing system. However, not every roof is a good candidate for coating. We'll inspect your roof and determine whether restoration or replacement is the better option.

  • What is a roof overlay?

    A roof overlay involves installing a new roofing system over an existing roof without completely removing the original roofing materials. Depending on local building codes and the condition of the existing roof, an overlay can be a cost-effective alternative to a full tear-off. Our team can determine whether your property qualifies for this option.

  • How often should a commercial roof be inspected?

    Most commercial roofs should be inspected at least twice per year, typically in the spring and fall. Additional inspections are also recommended following major storms or severe weather events.

  • What are the signs of commercial roof damage?

    Common warning signs include:

    • Water stains on ceilings
    • Active roof leaks
    • Ponding water
    • Cracked or damaged membranes
    • Loose flashing
    • Visible roof deterioration
    • Increased energy costs
    • Frequent repair needs

    If you notice any of these issues, it's a good idea to schedule a roof inspection.
