Commercial Roofing Repair and Replacement


Manchester Roofing Systems is a commercial roofing contractor. We install, maintain, and repair commercial, industrial, and institutional flat and low-slope roofing systems in the Tri-State area (PA, NJ, DE).


Since our founding in 1993, integrity & lasting value have been our core values. We can install any commercial flat roofing system, but we recommend and specialize in Duro-Last®, The World’s Best Roof© roofing for a number of significant reasons.

Since 1978, Duro-Last® has provided a much better value in commercial roofing:

  • warranties that include consequential damages
  • 80-85% seams are factory welded
  • Flashings also pre-fabricated not site made
  • Made with PVC not TPO
  • Every inch of welded seams inspected by Duro-Last

Duro-Last has to be very demanding of their contractors because their warranty includes coverage for consequential damages. We are not only a Duro-Last Certified Master Contractor, but also are called on by their inspectors to perform service work on their behalf.

Manchester Roofing Systems is a member of the Roofing Consultants Institute (RCI) and Rated A+ by the Better Business Bureau (BBB).

    Duro-Last® Recommended for Commercial Roofing

    The Duro-Last® Difference

    Duro-lastSince 1978, over a billion square feet of the Duro-Last® roofing system have been installed throughout North America including.  Building owners, roof consultants, architects, and specifiers choose Duro-Last for buildings of all types because it is:

    Prefabricated & Leak-Proof

    Every Duro-Last® single-ply roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the vinyl roof membrane in a controlled factory environment eliminates up to 85% of seaming that would otherwise be done on-site during rooftop installation, and improves the long-term performance of the roofing system. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection.

    The Duro-Last® membrane is classified as a CPA (co-polymer alloy) and is a proprietary thermoplastic formulation consisting of resins, plasticizers, stabilizers, biocides, flame retardant and UV absorbents. This membrane is then laminated to a weft insertion knitted scrim that is produced by overstitching a non-woven web. Because of this high-performance composition and professional installation, the Duro-Last® Roofing System provides you with a leak-proof roof.

    Durable Commercial Roofing System

    The Duro-Last roofing system, made from a PVC membrane, is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Duro-Last’s custom flashing components – made from the same vinyl roof membrane as our deck material – resist ponding water and help solve roof problems before they can occur. Plus with Duro-Last’s available Roof-Trak® Protective Walkway System, heavy equipment and maintenance traffic are easily managed.

    A mechanically attached roofing system, Duro-Last’s membrane has been successfully tested by Factory Mutual Research Corporation to withstand 150 lbs. of uplift resistance, which translates to approximately 140 m.p.h. winds.  While Duro-Last, as most roofing systems manufactures, excludes acts of God such as severe weather, in real life the Duro-Last Roofing System has even endured such devastating storms as Hurricane Hugo and Hurricane Andrew. In 1989, when Hurricane Hugo’s force destroyed many buildings in the Charleston, South Carolina area, approximately 130 Duro-Last roofs in that area remained undamaged. You will feel secure knowing that your Duro-Last Roof will protect you from even the most inclement weather conditions.

    Installed With No Disruptions

    Building occupants will hardly know a new roof is being applied, because installation is quiet and safe. The Duro-Last PVC roof membrane is mechanically-attached to the deck; edges and vinyl roof components are heat-welded together to complete the watertight, monolithic roofing system installation. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar, and no mess. And because it’s made from lightweight vinyl, a new Duro-Last roofing system can often be installed over an existing roof without an expensive tear-off, virtually eliminating dust or falling debris that could interfere with building activities or damage sensitive equipment.

    Energy-Efficient Commercial Roof

    PVC roofing systems make an important contribution to sustainable buildings, and Duro-Last is a charter partner in the EPA’s ENERGY STAR® Roof Products Program. Duro-Last is also a charter member of the Cool Roof Rating Council and a member of the US Green Building Council.

    Duro-Last’s Cool Zone® roof system has high reflectivity and emissivity values that reduce the amount of heat transferred into a building throughout its life span.  Cool Zone® roofs are saving significant energy and money for building owners all over North America and increasing comfort level and productivity for building occupants.

    From lowering a building’s energy consumption to helping facilities obtain LEED® credits to reducing the urban heat island effect, the Duro-Last Cool Zone® roofing system is a leading sustainable building product.

    Fire Retardant

    While EPDM and TPO membranes meet fire-safety standards, the Duro-Last PVC membrane will not burn. In Underwriters Laboratories (UL) tests, the Duro-Last Roofing System is regularly rated effective against even against severe fire exposure. This gives you peace of mind knowing that your Duro-Last Roof will stay strong even under harsh and unexpected conditions.

    Inspected by Duro-Last & The Industry’s Best Warranties for Commercial Roofs

    Every Duro-Last roofing job is inspected before, during, and after installation by a Duro-Last quality assurance specialist.  Duro-Last is so confident in the durability of their roofing systems that they provide the best warranties in the industry. Their standard comprehensive 15 YR full warranty is transferable, has no exclusions for ponding water, and provides coverage against consequential damages that result from defects in the Duro-Last® PVC material. Duro-Last also has 20-year warranties available.
