Commercial Deck Projects in Pennsylvania

Decks That Work as Hard as Your Business

Rooftops, Restaurant Patios & Venue Spaces—Built to Code

Alliance Deck Builders of Pennsylvania partners with business owners, developers, and architects to design and build commercial decks that meet local code and stand up to heavy use. From rooftop lounges to restaurant patios, we create custom outdoor structures that add square footage, seating, and curb appeal. All framing, fasteners, and finishes are engineered for safety, longevity, and public use.

Outdoor Spaces That Work for Business and Code

Engineered Decks for Restaurants, Bars, Rooftops & More

Commercial decks face different demands than residential ones—more foot traffic, stricter codes, and tighter timelines. We build structures that meet all of them. Whether you're expanding your restaurant with outdoor seating or building a rooftop lounge, we design for load, flow, and durability. We also coordinate with your GC, architect, or inspector to keep things on schedule.

Custom Layouts That Match Your Brand & Footprint

Decks That Help Your Business Welcome More Guests

We don’t build generic. Every project is laid out to match your site and customer flow—whether it’s table service, self-serve, or event hosting. From rail height to seating zones, we design to maximize both safety and style. And we can match your colors, finishes, and branding cues. If you can dream it, we can build it—up to code and ready for your next customer.

Framed for Long-Term Use With Minimal Maintenance

Commercial-Grade Materials That Stay Safe and Solid

We use code-rated framing lumber, commercial-grade composite or PVC decking, and corrosion-resistant fasteners to ensure long-term safety. Railings are reinforced for crowd load. Surfaces are selected for slip resistance and easy cleaning. Whether your deck sees shoes, heels, or rolling carts—it’s built to hold up. It’s more than just a deck—it’s a revenue-generating space built to last.

Permits, Specs, and Site Coordination? We Handle It.

From Design to Inspection—We Stay Involved

We’re not just builders—we’re problem solvers. We handle permitting, load calculations, structural drawings, and final inspections. If your project requires stamped plans or coordination with other trades, we stay involved to keep everything moving smoothly. You focus on your guests. We’ll focus on making the deck safe, clean, and ready to use.

Structural Framing That Meets Commercial Standards

Rooftop decks require precise engineering—especially when supporting guests, furniture, and utilities. We build on steel, concrete, or wood-framed roofs with structural details tailored to your site. All materials meet commercial load specs and are installed with safety-first hardware and mounting systems. We work with your architect or provide our own specs to make sure every box gets checked.
