Designing a Better Deck with Walkable Roofing Pavers

If you have an elevated deck or raised patio, you probably already understand and appreciate the value of an outdoor living space in the Hampton Roads region with our year-round mild weather.

Whether you invested in the deck yourself, or it came with your property when you purchased it, you also probably understand and appreciate how much maintenance and upkeep these decks require. You may be seeing boards that have warped, splintered, or gone gray; a surface that needs sanding and resealing every couple of years; or just an overall look that feels dated and tired. And if you are, you’re probably starting to weigh your options for repairs or replacements.

The obvious choices are what most people gravitate toward: replace the wood with composite decking, re-board the whole thing, do extensive sanding and resealing or put down concrete pavers and call it done. All of those are reasonable paths, but there is another path that you may not have considered that is a great option for elevated decks and raised patios in particular: walkable rubber composite roofing pavers.

These are the same materials used to create rooftop terraces and walkable flat roof surfaces, but it turns out that everything that makes them excellent for a rooftop makes them excellent for a deck, too.

The Usual Suspects

Wood decking is a popular choice because of cost as well as the warmth and aesthetics it brings to a space, but it requires a real maintenance commitment, especially in a coastal environment like Hampton Roads. The humidity, the salt air, the wet, rainy springs and blazing summers can take a toll. Wood warps, splits, splinters, fades, and eventually rots if it isn’t kept up. Pressure washing, sanding, staining, and sealing is a recurring cycle that costs time and money year after year, and inevitably the wood will get to a state where it needs to be fully replaced.

Composite decking was developed largely to solve those problems, and it does address some of them. It won’t rot or splinter, and it requires less maintenance than wood. However, it can get uncomfortably hot underfoot in direct summer sun, which anyone who’s walked barefoot across a composite deck in July in Virginia Beach can attest to. And in rooftop or terrace situations, it isn’t designed to account for drainage, waterproofing, or the specific stresses of a surface that’s also functioning as a protective layer over a structure below. In addition to that, it can become very costly depending on the size of the deck you’re replacing.

Concrete pavers are durable and attractive, but weight becomes a real issue on elevated structures. Concrete is heavy, and a lot of it on an elevated deck puts serious structural stress on the framing, which on an older deck may already be showing wear.

The Unusual Suspect

Walkable rubber composite roofing pavers were engineered specifically for elevated, exposed surfaces, whether that’s a rooftop terrace or an elevated deck. Here are a few “pros” of this material that go beyond the rooftop.

  • They’re dramatically lighter than concrete. Elevate SkyPavers weigh roughly 35% of what comparable concrete pavers would. On an elevated deck, that’s a big difference. Less weight means less structural stress on the framing, which matters both for safety and for the long-term integrity of the structure.
  • Roofing pavers will not warp, splinter, gray out or rot. The material is inherently resistant to moisture, and in a region like Hampton Roads where humidity is a fact of life year-round that is a meaningful advantage.
  • They reflect heat rather than absorbing it. The TPO membrane that underlies the paver system is typically white and highly reflective. This keeps the surface temperature considerably lower than composite decking or concrete in direct sun. On a sunny summer afternoon at the Virginia Beach oceanfront, that makes a big difference for a surface to stay walkable and enjoyable rather than becoming a bed of coals you need to navigate in bare feet.
  • Elevate SkyPavers carry a 20-year warranty and have a potential lifespan of up to 50 years. Compare that to a wood deck that needs significant attention every few years, and the math on long-term cost starts looking very appealing.
  • And importantly, they look good. Walkable pavers are available in a wide range of colors that can be selected to complement your home’s exterior. The finished surface is clean, modern, and attractive.

Roofing Paver Installation

These systems work in layers. First the existing deck surface will need to be evaluated to ensure it’s structurally sound. This step is critical and should be done by a qualified contractor who can tell you whether any framing repairs are needed before any additional weight is added. From there, a TPO waterproofing membrane is installed, followed by a drainage mat, and then the pavers are set on top. The pavers aren’t permanently adhered, which means the surface beneath remains accessible and the system can be adjusted if needed.

The result is a surface that protects the structure below while providing a durable, attractive, walkable surface above – exactly what a good deck surface should do.

As with any roofing or elevated surface project, installation should be handled by a licensed contractor with experience in this specific material. The system has its own requirements and best practices and getting it right matters both for performance and for warranty purposes.

A Good Fit for Hampton Roads

Elevated decks and raised patios are common throughout Hampton Roads: second-floor decks on oceanfront and ocean-block homes, raised patios on homes with grade changes, balconies on multi-story townhomes in Virginia Beach, Norfolk, and Chesapeake. Many of these surfaces were built with wood and are now at or past the point where they need an upgrade.

If you’re already thinking about what to do with an aging deck, it’s worth adding roofing pavers to the conversation before you default to the familiar options. For elevated surfaces especially, the combination of low weight, durability, heat reflectivity, and longevity makes a truly compelling case.

Andrews Roofing has experience with walkable paver installations across Hampton Roads, including in the demanding coastal environments where these materials really prove their worth. If you’d like to talk through whether this approach makes sense for your deck or raised patio, contact us today. We’re happy to take a look at your home’s specific situation and walk you through the options.

Roofing 101: Steep Slope vs. Low Slope

All roofs can be divided into two categories: steep and low slope. Low slope roofs have become increasingly popular on residential structures thanks to their clean, modern design and their ability to accommodate patios, gardens and more.

It’s important to understand the difference between the two when determining what type of structure to install, replace or repair or when choosing appropriate roofing materials.

Steep Slope
Steep slope roofs are technically any roof with a slope of 25% or more. They consist of five basic components:

  1. Roof covering – this could be shingles, tile, slate, cedar shake, or metal, as well as the underlayment that sits beneath them to protect the sheathing from weather.
  2. Sheathing – this is the board or sheet materials that are directly attached to the roof rafters that make up the roofline. This material must be covered by an underlayment material and roofing material (above) in order to remain structurally sound.
  3. Roof structure refers to the rafters and trusses that are structurally supporting the roof sheathing. This is the framing of the roofline which is a part of the skeleton of the house.
  4. Flashing is usually sheet metal that is installed at any point on a roof where there are joints, valleys, vents or chimneys. They function to prevent water seepage at these vulnerable spots.
  5. Drainage is a critical component of the overall roof design. It ensures that water is shed from the roof in a way that doesn’t compromise the structure at any point. Drainage has to be considered when designing the layout, shape and slope of any roof structure.

Low Slope
For all intents and purposes, a “low slope” roof is usually flat, but technically it refers to any roof that is between 0% and 24% sloped. They also consist of the same five basic elements, but the details differ somewhat.

  1. Roof covering for low slope roofs often consist of a single-ply membrane such as TPO, E.P.D.M., Modified Bitumen, or PVC. It is also common to see what are called “built up systems” which are composed of multiple layers of sheet materials and asphalt, often covered with a gravel coating. Other material options include spray foam or metal. All materials require an underlayment between them and the roof sheathing.
  2. Sheathing for low slope roofs can differ quite a bit from steep slopes. There are some structures with basic wood boards like a residential structure, but you may also see metal, concrete, gypsum, tectum and other fibrous materials.
  3. Roof structures of a low slope roof are conceptually the same – rafters, trusses and joists that support the sheathing, but the materials here may differ as well and could be steel, wood, or concrete.
  4. Flashing does not differ much from a steep slope installation and serves the same purpose to prevent water seepage at vulnerable spots.
  5. Drainage for a low slope roof is critical since the basic design of it does not shed water the way a steep slope roof does. For low slope roofs with any sort of incline, gutters, internal drains and downspouts can be effective. For truly flat roofs, special design considerations need to be made, and options like stepped slope insulation may be a safer bet.

Either roof can have its challenges. Obviously steeper slopes are more difficult to access and for shingled steep roofs, they will have a harder time fighting gravity over time. Mansard shingled roofs, for example, sometimes have nails tear through the shingles as they age. On the other hand lower slopes that are “walkable” and shingled, but still have a slope that falls within the shingle manufacturer’s specifications for shingle installation, can present greater challenges with wind-driven rain getting under the shingles, debris accumulation, needing additional barriers for protection such as ice & water shield, etc.

Any solid roofing solution – whether it’s for a home or commercial building – should balance all five of these components. At Andrews Roofing, we address each of these components equally when consulting with clients and assessing roofing needs. While the roof covering may have the most visual impact, we understand that everything below that is just as critical. If you have questions about what type of roof is ideal for your structure, or if you need a steep or low slope roof repaired or replaced, contact Andrews Roofing. We have decades of experience in both commercial roofing and residential roofing construction in Hampton Roads and we’d be happy to come out and give you an estimate and professional recommendation.

Create More Usable Space with Roofing Pavers

Flat roofs often go completely unnoticed when in reality they can be excellent usable space.

In fact, walkable roofing surfaces allow flat roofs and decks to become not just usable, but more energy efficient and sustainable in many cases.

What is a Walkable Roof?
A walkable roof surface must be flat, strong enough to bear the appropriate amount of weight, and must meet the local building codes for safety regarding railings or walls around the exterior of the walkable space. In many cases, industrial buildings have flat roofs that are walkable, but are often just used for maintenance and HVAC access needs. In residential homes, walkable roof surfaces may be porches or balconies as well as flat rooftops. Locally around the Virginia Beach area we also see cupolas, widows’ walks, crows nests, sun decks and more.

What types of materials work for walkable roofs?
For high traffic roofs, composite roofing pavers are a durable and attractive option. Roofing pavers are generally made of rubber, and in many cases they are made almost entirely from recycled materials. This makes them an ecologically friendly option. Their lifespan also makes them a sustainable option, as they can last up to 50 years, further reducing waste.

How do rubber pavers work?
If you’re interested in creating a walkable roof with rubber pavers, it’s critical to use a roofing contractor experienced in this material. They will be able to talk to you about whether or not the roof surface in question is indeed up to code and weight bearing. They will also know how best to lay the foundation for these pavers so that proper drainage is achieved. Generally, a roof consists of wood sheathing which is then covered by a thermoplastic polyolefin (TPO) membrane roofing material, then a roof drain mat and then the pavers are placed on top.

How are rubber pavers eco-friendly?
The TPO material used as the base of most walkable roofs is usually white, which reflects light and heat, making the roofing structure highly efficient. On top of that, the rubber pavers are only 35% the weight of regular concrete pavers, and our brand of choice, Elevate Sky Pavers, are made of 95% recycled tires. These pavers also come in five different colors to match your needs and aesthetic and come with a 20 year warranty. For many businesses and homeowners, walkable roof surfaces with well draining roof pavers are an excellent place to create a rooftop garden. With full sunlight, plants can thrive in this scenario without the concern of weeds or using precious yard space. Not to mention the additional outdoor living space a walkable roof can create.

Can rubber pavers be used for decks and balconies?
Many of the installations we do with rubber roofing pavers are for second floor balconies and decks. This material is a great option for these areas as they are lighter than other material options such as concrete and are more durable than wood decking. They also reflect heat and are comfortable to walk on. Thanks to the color variations they also look attractive enough to be used in spaces that are directly attached to the exterior of a home.

Who should install walkable roof surfaces?
As with all roofing jobs, walkable rubber roofing pavers should be installed by a qualified and experienced licensed roofing contractor. Do the research to find a company who has experience with this material as its implementation and installation are unique. At Andrews Roofing, we have experience with these specific roofing materials, especially for oceanfront homes and homes looking to take advantage of the beautiful water views in the Hampton Roads area. If you’ve been thinking about making the most of your flat roofing or decking surface, please give us a call. We’d be happy to talk to you more about the feasibility and benefits of these roofing materials.
