Roofing Repair & Maintenance

Having a roof problem? We have skilled technicians capable of evaluating your roof and assessing the situation. PSI can provide a comprehensive, site-specific report with recommendations and correlating cost estimates.

We can then review the report in-house or on-site for thorough understanding. This knowledge will empower the building owner to make informed decisions about facility conditions and expenditures.

The roof may or may not be under warranty, but needs some repair. Addressing repairs when needed ensures maximum long-term performance of your roofing system. If not addressed, simple problems may be exacerbated by seasonal environmental factors.

Autumn debris may be causing poor drainage. Spring rains that don't drain quickly can cause water to infiltrate at a damaged or deteriorated roof area. Debris removal and flashing repair may be all that is necessary to minimize further water damage and keep the system performing well long-term.

Maybe the roof is older and could benefit from more extensive TLC. Often a small investment now in repairs and preventative maintenance is just a fraction of the cost to re-roof. Repair and maintenance can postpone the need for a much larger investment of total replacement. It also gives the building owner an opportunity to budget for such expenditure.

When a new roof is the only reasonable option, we can discuss the facility needs, expectations, and cost parameters to develop the best solution possible. With decades of roofing experience, PSI can offer sound advice and competitive solutions. We can then complete the installation with quality products and outstanding workmanship.

Whatever the need, we can partner with you to assess and resolve your facility's roofing issues. Contact Progressive Services, in Dover, Pennsylvania, for services that give your property added weather protection.

    Oriole Park at Camden Yards Baltimore, MD

    On a summer day, the Steelight sunscreen is a welcome feature of the Oriole’s vintage-style ballpark. Cooperation was essential when so many trades are working at once with a tight work schedule. And with even tighter surroundings, coordination was also vital to this unique installation – along with a helicopter.

    This complex installation was no ‘walk in the park.’ Every project with a tight work schedule and multiple trades on-site requires much coordination and cooperation. That was expertly achieved in this beautiful yet complicated application. The 61,000 sf overhead sunscreen enjoyed by fans is a Steelight Panel System. Due to very limited access, a crane just wasn’t an option at this job site. So the panels were placed via helicopter- a uniquely creative solution. Our competent team of thoroughly trained professionals completed the install, ensuring optimum performance. Other low-slope roofing within the facility utilizes Carlisle SynTec Adhered EPDM systems as well.

    Mandarin Oriental Hotel Washington, DC.

    The Mandarin Oriental Hotel with its Petersen Redi-Roof metal mansard is a beautiful addition to the Washington DC landscape. But given the surroundings, safety was a key element to this installation. PSI achieves high safety standards while never compromising on the finished project.

    This premier landmark of Washington D.C. is a 9-story high structure showcasing mansard style Petersen Redi-Roof Batten Metal Panels with a Carlisle Syn-Tec Ballasted EPDM low-slope roof behind. This project offered extreme work challenges typical to a confined urban and marine surrounding within a bustling business and tourist locale. Safety is paramount in roofing and was clearly a critical component of this project. PSI maintains an excellent safety record and strives to achieve OSHA and state safety requirements for every project. We work to develop site-specific safety plans to meet the unique challenges of the job wherever it may be.

    Armed Forces Medical Examiner Facility Dover Air Force Base, DE

    PSI is pleased to install and service a variety of public and private sector projects. Environmental concerns are playing a greater role in design and construction for both. As LEED compliance becomes more common, we provide capability and experience with paperwork and products to achieve these requirements.

    The challenge with LEED projects, and often government work in general, is the paperwork more than the field work. From MSDS to safety plans, security clearances to certifications, we’ve got it covered. We are capable of meeting LEED requirements with metal and single-ply through steep-slope, low-slope, and vertical applications. We are experienced in providing the supporting documentation required to be sure roofing and/or exterior wall panels properly contribute toward LEED totals. Here, 63,400 sf of Merchant & Evans Zip-Rib Metal Panels possess important recycle content as well as Energy Star compliance with colors meeting SRI standards.

    The Carlisle SynTec Adhered PVC is highly reflective and energy efficient, enjoying both Energy Star qualifications and LEED credits. Finally, Benchmark Designwall insulated wall panels add to the energy efficiency of the facility also offering multiple LEED credits. PSI is proud to have contributed significantly to this LEED design with such quality products. The result is a distinguished, ‘green’ facility worthy of servicing our country’s finest soldiers.

    Camp Hill Mall Camp Hill, PA

    When combining new construction with existing structures, there can be competing needs and expectations of both property managers and general contractors. PSI can work through job-site conditions to develop balanced solutions to meet the needs of both sides.

    PSI is responsive to both property managers’ and general contractors’ needs where re-roofing and renovation work is involved too. Here, the Petersen Snap-Clad Metal Panels provided a fresh aesthetic and continuity to the renovated facade. The Carlisle SynTec Adhered EPDM and Mechanically Fastened TPO Systems applied to the low-slope areas quickly kept the buildings dry during both critical interior renovations and new construction. PSI also maintained minimal disruption to ongoing retail functions at adjacent stores. For us and our customers, these systems offer excellent quality while staying within budget and on schedule.
