Do I Need a New Commercial Roof?

Here are key indicators to hire our commercial roofers in Manchester, NH for a replacement:


  • Frequent and Widespread Leaks: If your roof experiences multiple leaks across various areas, especially after each rainfall, it may indicate that the roofing system has reached the end of its lifespan. Persistent leaks can lead to significant water damage, mold growth, and compromised insulation, all of which can affect the structural integrity of your building.
  • Visible Membrane Damage or Deterioration: For commercial flat roofs, such as those made of TPO, EPDM, or modified bitumen, visible signs of wear like cracks, tears, blisters, or loose seams are red flags. These issues compromise the roof's ability to protect your building and can lead to further damage if not addressed promptly.
  • Ponding Water That Doesn't Drain: Flat roofs should have a slight slope to facilitate proper drainage. If you notice standing water that remains for more than 48 hours after a rainfall, it could indicate clogged drains or structural issues.
  • Escalating Energy Bills: A failing roof can compromise your building's insulation, leading to higher heating and cooling costs. If your energy bills have increased without a corresponding rise in usage, your roof's thermal efficiency may be compromised. Fortunately, our commercial roofers in Moultonborough, NH can handle a replacement with ease.
  • Age of the Roof: Most commercial roofs have a lifespan of 20 to 30 years, depending on the materials used and maintenance practices. If your roof is approaching or has surpassed this age range, it's advisable to have it inspected by a professional to assess its condition.
  • Accumulated Repair Costs: If you've been investing in frequent repairs without seeing lasting results, it may be more cost-effective in the long run to replace the roof. Ongoing repair expenses can add up and may not address underlying issues, leading to more significant problems down the line.
  • Interior Water Damage: Stains on ceilings or walls, mold growth, or damp insulation inside your building are signs that water is infiltrating through the roof. These issues not only affect the building's structure but can also pose health risks to occupants, making roof replacement a priority.
  • Visible Sagging or Structural Issues: If you notice sagging areas or visible damage to the roof deck, it's time to hire our commercial roofers in Manchester, NH. These issues indicate that the structural integrity of your roof has been compromised.
  • Damaged Flashing or Pitch Pans: Flashing and pitch pans are critical components that direct water away from roof penetrations. If these elements are damaged or deteriorated, water can seep into the building, leading to leaks and potential structural damage.
  • Visible Vegetative Growth: The presence of moss, algae, or other vegetation on your roof can indicate trapped moisture and poor drainage. Over time, this can lead to roof degradation and may require replacement if left unaddressed.


If you're observing any of these signs, it's essential to consult with our professional roofers Moultonborough, NH residents prefer to assess the condition of your commercial roof. At Sentry Roofing, we specialize in comprehensive roof inspections and can provide expert advice on whether repair or replacement is the best course of action. Schedule an evaluation and ensure the continued protection of your building.

  • How can I tell if my commercial building needs a new roof?

    Barring a major accident or damage to your commercial roof, it usually takes a professional commercial roofing installer to determine whether your building needs a new roof. Following a thorough inspection, during which we look for problematic leaks or extensive mold issues, among other things, we will be able to verify whether your building needs a new commercial roof or maintenance repair.

  • Is it possible to re-roof the existing roof?

    Depending on the extent of the damage, it might be possible to repair or recoat a roof. Once our installers have inspected your roof, we will discuss your options with you to determine the best course of action. 

  • What is the cost of a new commercial roof?

    The overall cost of a commercial roof comes down to a variety of factors, including the size of the roof, insulation required/requested, number of penetrations/units, and many other unique conditions. We believe in transparency at Sentry, which is why we will present you with estimates before we begin any work. 

  • How long does new commercial roofing last?

    Similar to cost, a host of factors from the materials used to the weather in your area, can impact a commercial roof’s longevity. In general, a well-maintained commercial roof system should be expected to last at least 30 years. Our team can advise you on what to expect from your specific commercial roof, following our review of the materials, location, and local weather trends.

  • How much time does it take to install a new roof?

    We can project a specific timeline with you once we know the materials, the condition of your existing roof (does it require replacing vs. repairing?), any seasonal, weather-related challenges, and how quickly we can pull the requisite permits. Generally speaking, commercial roof installations range from several days to a few weeks and are best determined on a case-by-case basis.
