5/5 - (1 vote)

Commercial roofing is a critical aspect of maintaining the integrity and functionality of any business property. In Pennsylvania commercial roofing must withstand diverse weather conditions, from harsh winters to hot summers. This article provides an overview of commercial roofing in Pennsylvania, highlighting key materials, considerations, and tips for choosing the right roofing solution for your business.

Modified Bitumen

Modified bitumen roofing is a durable option made from asphalt products. It is commonly used in Pennsylvania due to its ability to withstand extreme temperatures and its excellent waterproofing properties.

EPDM (Ethylene Propylene Diene Monomer)

EPDM is a synthetic rubber roofing membrane known for its durability and flexibility. It is resistant to UV radiation, making it suitable for Pennsylvania’s varying climate conditions.

TPO (Thermoplastic Olefin)

TPO roofing systems are popular for their energy efficiency and resistance to chemicals, punctures, and tears. TPO roofs are white, reflecting heat and helping to reduce cooling costs during hot summers.

Metal Roofing

Metal roofing is favored for its longevity, durability, and low maintenance. It can withstand heavy snow, high winds, and other harsh weather conditions common in Pennsylvania.

Built-Up Roofing (BUR)

Built-up roofing consists of multiple layers of bitumen and reinforcing fabrics, creating a robust and durable roof. It is ideal for flat or low-slope roofs commonly found in commercial buildings.

Key Considerations for Commercial Roofing in Pennsylvania

Weather Resistance

Pennsylvania experiences a wide range of weather conditions, including heavy snowfall, rain, and high winds. Choose a roofing material that can withstand these elements and provide long-term protection for your building.

Energy Efficiency

Energy-efficient roofing materials, such as TPO and metal, can help reduce energy costs by reflecting sunlight and reducing heat absorption. This is especially beneficial during the hot summer months.

Durability and Longevity

Investing in durable and long-lasting roofing materials can save money in the long run by reducing the need for frequent repairs and replacements. Consider the lifespan of different roofing options when making your decision.


While upfront costs are an important consideration, it is also essential to evaluate the long-term costs of maintenance, repairs, and energy savings. A higher initial investment in quality materials can lead to lower overall costs over the roof’s lifespan.

Building Codes and Regulations

Ensure your chosen roofing solution complies with Pennsylvania’s building codes and regulations. A professional roofing contractor will be familiar with these requirements and can guide you through the process.

Choosing the Right Commercial Roofing Contractor

Experience and Expertise

Select a contractor with extensive experience in commercial roofing, particularly with the materials and systems you are considering. Experienced contractors can provide valuable insights and high-quality workmanship.

Local Reputation

Choose a contractor with a strong local reputation. They will have a better understanding of Pennsylvania’s climate and building codes, ensuring your roof is installed correctly and meets local standards.

References and Reviews

Check references and read online reviews to gauge the contractor’s reliability and quality of work. Positive feedback from previous clients is a good indicator of a reputable contractor.

Detailed Estimates

A reliable contractor should provide a detailed written estimate that includes labor, materials, and any additional costs. This transparency helps you understand the scope of the project and avoid unexpected expenses.

Warranties and Guarantees

Ask about the warranties and guarantees offered on both materials and workmanship. A strong warranty indicates the contractor’s confidence in their work and provides peace of mind for you as a business owner.

Maintenance Tips for Commercial Roofs

  • Regularly inspect your roof for damage or wear, especially after severe weather events.
  • Keep gutters and downspouts clean to prevent water buildup and potential leaks.
  • Remove debris from the roof surface to prevent damage and ensure proper drainage.
  • Schedule regular maintenance with a professional roofing contractor to identify and address potential issues early.
  • Ensure proper insulation and ventilation to maintain energy efficiency and extend the roof’s lifespan.


Choosing the right commercial roofing solution in Pennsylvania involves considering various factors, including weather resistance, energy efficiency, durability, and cost. By selecting the appropriate materials and working with a reputable contractor, you can ensure your commercial roof provides long-term protection and performance. Regular maintenance and timely repairs are also essential to extending the life of your roof and protecting your investment.
