Roof Deck vs Rooftop: Key differences, cost and uses

Introduction

When deciding between a roof deck vs rooftop, key differences emerge. These impact budgets, structures, aesthetics and usage over the long term.

Roof decks raise spaces slightly above the roofline itself. Rooftop projects integrate living areas directly on top of the roof. This requires more complex reinforcements.

This article dives into the core contrasts between the two options. Aspects covered include key differences, construction costs, and comparison.

This helps match choices with homeowner lifestyle purposes best. Understanding roof deck vs rooftop early allows tailoring everything else around realistic foundations.

Adding outdoor living space at the top of a building gives opportunities for great views, sun access, and unique gathering areas.

But should you build out a new roof deck or just access the existing rooftop?

Roof deck vs rooftop differences

There are some fundamental differences between a roof deck and rooftop when it comes to accessibility and construction:

Roof decks are purpose-built outdoor living spaces, intentionally designed for safety and functionality:

  • Decking materials like wood or composite boards
  • Railings, stairs, and access points incorporated
  • Often have amenities like lighting, kitchens, planters

Rooftops are simply the roof itself – the surface underneath solar panels, HVAC equipment, etc:

  • Typically asphalt shingles, membrane surface, or gravel
  • Primarily accessed only for equipment maintenance
  • Can require new railings, anchors for fall safety

“We built a large roof deck for parties and outdoor yoga that feels like an extension of our living space. Just accessing the plain rooftop wouldn’t have met our needs for an inviting, comfortable gathering area.” – Amanda D., homeowner

Constructing a new roof deck space involves more upfront investment than basic rooftop access:

For a 10′ x 15′ roof deck, the total cost would be $4,500 to $7,500 vs. $2,250 for rooftop access.

However, rooftop access has ongoing costs for maintenance and safety checks of equipment like HVAC units.

Roof decks may require less of this if built around existing infrastructure.

Roof Deck and Rooftop Uses

Roof deck Uses

  • Outdoor kitchens and dining areas
  • Sunbathing and outdoor lounging
  • Gardens, green space in urban areas
  • Entertainment, parties, events
  • Gyms, yoga studios

Pros

  • Usable outdoor living area
  • Space for gathering, events
  • Often better views without equipment
  • Decks are modular, movable

Cons

  • More complex build, higher upfront costs
  • Concentrated weight impacts structure
  • Exposure can limit materials lifespan

Rooftop Uses

  • HVAC systems, air conditioners
  • Solar panel installation
  • Other mechanical or telecom equipment
  • Chimneys, vents, skylights

Pros

  • Lower incremental cost to access
  • Minimal new construction
  • Easy equipment access for maintenance

Cons

  • Safety; limited existing railings or barriers
  • Access can impact roof integrity over time
  • Space constraints around equipment

When deciding whether to build a new roof deck or simply access your existing rooftop, consider:

  • Usage: What activities do you want the space for? Entertainment demands more built-out deck.
  • Access: How easily can people traverse the current rooftop surface?
  • Budget: Roof decks require more investment upfront.
  • Safety: Evaluate fall risks, anchor points on current rooftop.

Prioritizing your goals for outdoor space, budget, and usage will determine which option makes the most sense. A purpose-built roof deck creates a new gathering area, while rooftop access lightly expands existing infrastructure.

Conclusion

Determining whether to build a new roof deck or simply access your rooftop depends greatly on your intended use, budget, and priorities.

Roof deck vs rooftop comparison will help you to select a option according to your needs and goals.

Roof decks require more upfront investment but create highly functional outdoor living areas for dining, entertaining, lounging, and more. They transform empty rooftop space into beautiful garden retreats and party venues.

On the other hand, rooftop access provides simpler, cheaper expansion of outdoor space primarily for maintenance and installation of mechanical equipment. Rooftop use is limited by existing safety barriers and cramped equipment.

Carefully evaluate the pros, cons and costs against your goals. Building upwards with a roof deck or lightly stepping out onto an unchanged rooftop each serve different roles. Determine what’s right for your needs and resources.

FAQ’s

What is the meaning of roof deck?

A roof deck refers to a purpose-built, outdoor living space constructed on top of a building’s roof. It often consists of weather-resistant decking materials, as well as railings, stairs, furniture, and other amenities transforming the rooftop into a gathering area for residents.

Are roof decks worth it?

For those prioritizing outdoor living space, events, and views, roof decks can certainly be worth the higher initial investment over basic rooftop access. The ability to actively use the space for lounging, dining, gardens and parties provides great value from the build cost.

How much value does a rooftop deck add?

Homes with roof decks may boost property value by 10-15% over similar places without the elevated outdoor area. Rooftop decks expand usable space for owners, and become a differentiating feature for interested buyers as well.

What are the benefits of having a roof deck?

Key benefits of roof decks include added outdoor living areas; space for entertaining, dining, and events; better light and views; the ability to garden and add greenery; and expanded areas for relaxation. They deliver amenities without reducing interior space.

How much weight can a roof deck hold?

Most modern building codes require roof deck framing that can handle 40-60 pounds per square foot – enough for tables and chairs, moderate crowds, planters, and other typical features. Permits account for concentrated weight during construction.
