Why Install a Rooftop Deck in Philadelphia?

A rooftop deck is more than just an outdoor space—it’s a lifestyle upgrade. In densely populated urban neighborhoods, rooftop decks offer an opportunity to enjoy fresh air, entertain guests, or simply unwind with a view.

Key Benefits of Rooftop Decks:

  • Scenic City Views: Enjoy unobstructed views of the Philadelphia skyline, Ben Franklin Bridge, or lush tree canopies in neighborhoods like Chestnut Hill or Queen Village.
  • Expanded Outdoor Living: Add space for grilling, dining, lounging, or even gardening—right on top of your home or business.
  • Energy Efficiency: Rooftop decks can act as a layer of insulation, improving your home’s energy efficiency by reducing heat absorption through the roof.
  • Increased Property Value: A well-designed rooftop deck adds significant resale value, especially in competitive real estate markets like Fishtown, Rittenhouse Square, and Graduate Hospital.

Deck Construction Techniques for Rooftops

When building rooftop decks, we employ specialized construction techniques to ensure structural integrity, waterproofing, and aesthetic appeal. Our options include:

  • Floating Decks: Ideal for decks built over flat roofs, floating decks are not permanently secured to the structure but rather placed on top, providing a versatile and adaptable outdoor space.
  • Pedestal Systems: We offer proprietary pedestal systems that provide stable, level, and serviceable deck surfaces over roof membranes, ensuring durability and longevity.

Rooftop Deck Material Options

We offer a variety of durable, low-maintenance, and attractive materials to fit your vision and budget:

Composite Decking

  • Brands: Trex, TimberTech, MoistureShield
  • Benefits: Fade-resistant, rot-proof, made from recycled materials, minimal upkeep

Natural Wood Decking
