We needed to replace a 25 year old roof (complete tear off and chimney cap). After getting estimates and information we chose Trenton Roofing and are extremely happy we did. The process with this company was effortless. They were quick to respond and prompt with all appointments and correspondence. We found Trenton Roofing and their employees to be friendly, professional, courteous, clean, and respectful to us and our home. The roof was replaced in one day. They showed up early, completely protected all vegetation surrounding our home, and cleaned up before leaving. Trenton Roofing outperformed our expectations. Their fair price was not only competitive, but beat the competition. The new roof looks great and definitely enhances the look of our home. We had no issues or disappoints throughout the entire process. We would definitely choose Trenton Roofing & Siding for any future need.read more

They worked quickly, showed great craftsmanship, and managed to complete the entire tear-off and replacement in one day.Thorough Cleanup: Roofing tear-offs are messy, but the team ran magnetic sweepers through our yard and driveway. . They left the property spotless—not a single stray nail in sight.What impressed me the most was the complete lack of high-pressure sales tactics.

FREQUENTLY ASKED QUESTIONS
HOW LONG DOES COMMERCIAL ROOF SEALING LAST?
A professionally installed commercial roof sealing system can last anywhere from 10 to 20 years, depending on the coating selected, the condition of the existing roof, and how well it’s maintained. In New Jersey and Eastern Pennsylvania, roofs must withstand heavy rain, snow, freeze-thaw cycles, UV exposure, and temperature swings throughout the year, making proper installation especially important. Regular inspections and preventative maintenance can help maximize the life of your roof and delay the need for a full replacement.
IS THERE A WARRANTY?
Yes. Our commercial roof sealing systems are backed by strong manufacturer warranties, with qualifying systems offering up to a 20-year No Dollar Limit (NDL) warranty covering both materials and labor. We’ll explain your warranty options during your inspection so you know exactly what protection comes with your investment.
CAN YOU SEAL ANY TYPE OF COMMERCIAL ROOF?
Most commercial roofs can be successfully restored with a liquid-applied sealing system, including metal, TPO, EPDM, modified bitumen, built-up roofing (BUR), and concrete roofs. However, every roof is different, and not every roof is a good candidate for restoration. During our inspection, we’ll evaluate the roof’s condition, identify any underlying issues, and recommend whether sealing or replacement is the better long-term solution.
HOW MUCH WILL I SAVE COMPARED TO REPLACEMENT?
In many cases, commercial roof sealing costs 40% to 70% less than a full roof replacement, while extending the life of your existing roof for years. Because the existing roofing system typically remains in place, property owners also avoid costly tear-offs, landfill fees, and disruptions to daily business operations. Every building is different, so we’ll provide a detailed estimate comparing your restoration and replacement options.
WHAT KIND OF WARRANTY COMES WITH TRENTON ROOFING'S SEALING SERVICE?
We offer Industry-Leading Warranties to give property managers ultimate peace of mind. Depending on the system you select, we provide up to a 20-Year NDL (No Dollar Limit) Manufacturer Warranty, ensuring your investment is fully protected against material and labor defects.
WHAT DOES A "RENEWABLE" WARRANTY MEAN?
Many commercial roofs that appear to need replacement can actually be restored. If your roof is structurally sound but showing signs of aging, minor leaks, weathering, or ponding water, a liquid-applied roofing system may be an excellent solution. However, if the roof deck has significant structural damage or the insulation is extensively saturated, replacement may be the better investment. Our comprehensive roof inspection will identify the condition of your roof and provide honest recommendations based on its long-term performance, not simply its age.
HOW DO I KNOW IF MY COMMERCIAL ROOF IS AG OOD CANDIDATE FOR SEALING, OR IF IT NEEDS TO BE REPLACED?
If your roof is structurally sound but experiencing minor leaks, ponding water, or weathering, it is an ideal candidate for a liquid-applied system. However, if the underlying deck is severely rotted or the insulation is completely saturated, a replacement may be necessary. We provide a thorough inspection to determine the best route for your property. The age of the roof isn’t necessarily the deciding factor, the condition of the roof is the most important factor.
HOW DOES ROOF SEALING HELP WITH "PONDING WATER" ON FLAT ROOFS?
Ponding water is one of the most common challenges facing flat commercial roofs throughout New Jersey and Pennsylvania, especially after heavy rain, snow melt, and winter storms. Traditional roofing seams are often the first areas to deteriorate under standing water, allowing moisture to work its way into the building. Our seamless liquid-applied roofing systems eliminate many of those vulnerable seams, creating a continuous waterproof membrane engineered to withstand long-term exposure to ponding water.
IS COMMERCIAL ROOF SEALING ENVIRONMENTALLY FRIENDLY?
Yes. Commercial roof sealing is one of the most sustainable ways to extend the life of an existing roof because it avoids tearing off and disposing of thousands of pounds of roofing material that would otherwise end up in a landfill. Many roof coating systems also feature highly reflective finishes that help reduce rooftop temperatures during New Jersey’s hot summer months, lowering cooling costs and improving overall energy efficiency.
HOW DO WE GET STARTYED, AND HOW QUICKLY CAN I GET AN ESTIMATE?
Getting started is easy. Simply complete the contact form on our website or give our office a call, and we’ll schedule a convenient time to inspect your commercial roof. During the inspection, we’ll assess the roof’s overall condition, identify any areas of concern, and provide a detailed, no-obligation estimate with recommendations tailored to your building, budget, and long-term goals.
