Commercial roofing

1. 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. 

2. Instead of a new roof, 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 in order to determine the best course of action. 

3. 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, the number of skylights and vents, as well as the required materials. We believe in transparency at Sentry, which is why we will present you with estimates before we begin any work. 

4. 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, built-up roofs should last anywhere from 10-15 years; spray polyurethane foam has a durability that can exceed 45 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.

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

We can project a specific timeline with you once we know the materials, 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.
