Commercial properties across New Jersey require roofing systems that support daily operations, regulatory requirements and long-term asset performance. When you need roofing services for your business, choose a contractor experienced in complex commercial environments and large-scale systems. At David Maines & Associates, Inc., we deliver commercial roofing solutions designed to protect facilities, reduce risk and support uninterrupted business operations.

A Commercial-First Roofing Partner

David Maines is a commercial roofing contractor serving organizations throughout the Mid-Atlantic, including facilities across New Jersey. We work exclusively with commercial clients, supporting manufacturers, government organizations, schools and large commercial facilities. When you work with us, you benefit from a structured process that prioritizes communication, safety and schedule control from the first site visit through project completion.

We begin every project with a detailed evaluation to identify the most effective roofing system for your building’s size, usage and performance goals. Our recommendations focus on function, longevity and return on investment rather than a single preferred product.

Flat Roofing Systems

Flat and low-slope roofs are common across New Jersey’s commercial landscape. Flat roofing projects require careful planning around drainage, insulation and rooftop equipment. David Maines installs roofing systems specified by trusted manufacturers such as Firestone, Tremco, Carlisle and Garland, ensuring compatibility with your facility and long-term service needs.

If water intrusion occurs, our flat roof leak repair services focus on fast identification, targeted repairs and minimizing operational disruption.

Metal, EPDM and TPO Roofing Expertise

For facilities that require durability and extended service life, metal, ethylene propylene diene monomer (EPDM) and thermoplastic polyolefin (TPO) are reliable solutions.

  • Metal: Metal roofing is durable and long-lasting. As an experienced commercial metal roofing contractor, we provide proper detailing, secure fastening systems and assemblies designed for large commercial structures.
  • EPDM: Many organizations choose EPDM roofing based on building use. EPDM provides proven flexibility and long-term serviceability.
  • TPO: TPO offers reflective performance that supports temperature control and energy efficiency. We support specialized applications such as TPO roofing installation for restaurants, where cleanliness, durability and performance consistency are critical.

While the cost to replace a commercial roof in New Jersey varies based on roof size, insulation requirements and access conditions, detailed inspections and transparent scopes of work help support informed planning.

Ongoing Maintenance for Long-Term Protection

Preventive care plays a key role in extending roof life and avoiding unexpected disruptions. Roof maintenance plans help identify developing issues early, reduce emergency repair needs and support warranty compliance. Routine inspections also improve budget forecasting and long-term facility planning.
