Look Up: Finding the Outdoor Space You Didn’t Know You Had

Spring is almost here, and if you’re like most Hampton Roads homeowners, you’re probably already thinking about how to start shifting life more outdoors.

Maybe you’re planning to freshen up the patio furniture, fire up the grill, or finally tackle that landscaping project you’ve been putting off since fall. Outdoor living is one of the biggest perks of life in this region thanks to our mild temperatures, fresh coastal air and gorgeous spring weather.

But when you think about making the most of your outdoor space, are you only thinking horizontally? Most people default to ground-level thinking when it comes to outdoor living: the backyard, a patio, maybe a raised deck off the back door, which makes sense for most properties. But for a significant number of homes across Hampton Roads, the most valuable and underutilized outdoor space isn’t on the ground – it’s above your head.

With walkable roofing pavers, almost any flat roof surface can be transformed into functional, attractive outdoor living space. And in a region with as many potential water views as ours, the payoff can be big. To learn more about exactly what walkable pavers are, read our earlier blog on the material, but read on here to see how they can create possibilities in your own property that you may not have ever considered.

A Region Primed for Rooftop Life

Hampton Roads sits at the intersection of the Chesapeake Bay, the Atlantic Ocean, the Elizabeth River, the Lafayette River, the Lynnhaven, and dozens of creeks, inlets, and waterways threading through Virginia Beach, Norfolk, Portsmouth, Chesapeake, and beyond. We are, by almost any measure, one of the most water-rich metropolitan areas on the entire East Coast.

Water views in this region aren’t just nice to have – they’re a premium asset. Properties with water views command significantly higher prices, and for good reason. We all know that there’s something special about an unobstructed view of any one of these beautiful waterways.

The problem is that while a lot of Hampton Roads homeowners technically live near the water – even a stone’s throw distance – they miss the view completely because they’re experiencing it from the wrong elevation. Neighboring structures, fences, mature trees, and the general density of coastal neighborhoods can block what would otherwise be a stunning sight line. But go up one or two stories, and the picture changes completely. Here are a few neighborhood-specific examples.

Chic’s Beach

If you’ve spent any time in the Chic’s Beach neighborhood of Virginia Beach along the Chesapeake Bay, then you know that many of the properties there are three-story townhomes packed closely together, many of them sitting within a short walk of the Bay. From the street or the backyard (if there is a backyard), the views are often modest at best, blocked by the neighbor’s fence, the next row of townhomes, or a screen of vegetation. But from the rooftop of many of these homes, suddenly the Bay is right there.

A walkable rooftop terrace on a home in Chic’s Beach doesn’t just add outdoor square footage, it adds a premium view that expands the way you can live in your home and how much there is to enjoy. Morning coffee with the sunrise over the water, or evening breezes watching the boats come into the inlet – those are now realistic visions for the right property with the right walkable rooftop paver installation.

The North End

The north end of the Virginia Beach Oceanfront is one of the most coveted and valuable stretches of real estate in the region. Oceanfront and ocean-block cottages and homes, many of them multi-story, sit along some of the most beautiful Atlantic coastline on the East Coast.

For true oceanfront homes, a rooftop deck is an obvious enhancement: more square footage, higher elevation, more expansive views that can even include sunset views from the right spot. But perhaps the more compelling case in this area is actually for the ocean-block properties – those sitting just one street back from the oceanfront. At ground level, an ocean-block home may have limited water views. Add a rooftop terrace, and a home that was a short walk from the ocean suddenly feels oceanfront from the right vantage point. That’s a meaningful difference, both for everyday enjoyment and for the property’s value and marketability.

Inland Views and Little Yards

Water views make for a compelling story, but a rooftop deck doesn’t require an ocean backdrop to be worth pursuing. For many Hampton Roads homeowners the issue is simply that they don’t have a large enough back yard to truly enjoy their outdoor space. It may also be too exposed, too shaded, too uneven or often – too soggy.

Older neighborhoods across Norfolk and Portsmouth were often developed with modest lot sizes. Backyards can be small, awkwardly shaped, hemmed in by utilities or HVAC equipment, or simply too shaded and enclosed to feel like a real outdoor retreat. Ground-level patios in dense neighborhoods often feel exposed to neighbors visible on all sides, without any privacy or separation.

A rooftop terrace solves several of these problems at once. It creates usable outdoor space without expanding the home’s footprint. It often feels considerably more private than a ground-level patio level, you’re above the fence lines, above the neighboring yards, with a sense of openness and seclusion that’s hard to achieve at the ground. A flat roof over a garage, a first-floor addition, or even a main structure that’s currently just sitting there collecting leaves and weathering quietly may represent more functional outdoor square footage than anything available at ground level.

Keeping in Mind: Building Codes, Zoning, and Feasibility

Of course, a rooftop deck is not a possibility in every home or in every neighborhood. The feasibility of a project like this depends on a number of factors that need to be evaluated before getting too far down the road.

Structural capacity is the most fundamental consideration. A flat roof intended to become a walkable terrace needs to be assessed by a qualified contractor to confirm it can safely bear the additional load which includes not just the pavers themselves, but furniture, people, and anything else you plan to put up there. Walkable roofing pavers like Elevate SkyPavers are significantly lighter than concrete alternatives, but structural review is still essential.

Local building codes and zoning regulations also come into play. For most cities in our region, a rooftop deck will require a permit, and there are often requirements around railings or parapet walls for safety that must meet specific height and load standards. Neighborhoods governed by homeowners associations may have restrictions on rooftop modifications or additions. HOA documents are worth reviewing early in the process.

The right first step is a conversation with an experienced roofing contractor who can give you an honest assessment of what’s possible on your specific property. Many projects that seem complicated on the surface turn out to be very achievable once someone with the right expertise takes a look. And for properties where a rooftop terrace genuinely isn’t feasible, there are often other flat roof surfaces — over garages, additions, or lower-level sections of the home — that may present a workable alternative.

How Walkable Pavers Work

A walkable roof surface is created by starting with a TPO (thermoplastic polyolefin) white flat roof membrane, which reflects heat and protects the structure below. On top of that a drainage mat is installed, with the composite roofing pavers placed on top. The pavers sit on the drainage mat without being permanently adhered, which means the roof below remains accessible and the system can be adjusted or removed if needed.

We work primarily with Elevate SkyPavers, which are made from 95% recycled rubber tires, weigh roughly 35% of what comparable concrete pavers would, and carry a 20-year warranty with a lifespan that can reach 50 years. They come in multiple colors, they reflect heat rather than absorbing it, and they’re comfortable underfoot.

Done correctly by a contractor experienced with this system, the installation protects the roof below while creating an attractive, durable surface above. For the full breakdown of materials, installation, and eco-friendly benefits, take a look at our earlier post on walkable roofing pavers.

Spring Is the Right Time to Start the Conversation

Walkable rooftop paver projects involve assessment by a roofing contractor and often a general contractor as well as permitting, scheduling and of course – construction. They do not happen overnight, so if your goal is to have a new outdoor space ready to enjoy by late summer or fall, spring is the time to start planning.

What’s the Difference Between a Shingle and Membrane Roof?

If you’ve been researching roofing repairs or replacements, you’ve probably come across several different roofing materials. The type of materials used for a roof depends on a lot of factors including the structure of the building, the building’s purpose and use, location, budget and local building codes. Two large categories of roofing materials are shingles and membranes. Both of these categories are made up of many different types of products and materials that are used for different purposes, so let’s dive in.

Steep Slope vs. Low Slope

The first factor in determining which of these two roofing methods will be used is whether the roof in question has a steep or low slope. Shingles are typically used on steep slope roofs, while membranes are used in flat or low slope roof situations. For the most part, membrane roofs are seen on industrial and commercial buildings, but can be found on residential properties as well, often as decks, over side and rear adjoining roofs. On residential properties, they are often found over sunrooms, utility rooms, or porches and can be used under decks and other walkable surfaces materials like pavers. Membrane roofs are quite common at waterfront properties and on new construction in the Hampton Roads/Tidewater area.

Types of Membrane Roofs

There are many different roofing membrane products on the market today, each with their own purposes and benefits. Below are four common flat and low slope roof membrane materials.

Thermoplastic polyolefin (TPO)

In the Mid-Atlantic region, TPO is becoming the low slope roofing standard. Because TPO is white, it is highly reflective, which means it’s efficient in keeping buildings cool. In fact, TPO roofs generally exceed the current energy efficiency standards and are a US Department of Energy, Energy Star rated roofing system, which some commercial structures may need to meet. TPO is also very durable thanks to its heat welded seams, and can last 20 to 30 years, making it a budget-conscious choice for businesses.

Ethylene Propylene Diene Terpolymer (EPDM)

EPDM is also a single ply membrane, but it is made of a rubber compound, rather than plastic like TPO. This material has been in commercial use for longer than TPO and has a strong reputation for durability. When properly installed, EPDM can easily last 30 years or more. However, if installed incorrectly or without proper maintenance, the adhesive treated seams can become vulnerable over the long term. Although EPDM roofs are usually black in color, meaning they are not as energy efficient as TPO, the material is 100% recyclable. There are also EPDM products that come in white, doubling their environmentally-friendly factor.

Polyvinyl Chloride (PVC)

PVC is a single ply membrane that is similar in appearance to TPO and is usually white, giving it similar energy efficient qualities. Other environmentally friendly aspects of PVC include its low petroleum content compared to TPO and EPDM. It’s also a recyclable material, even post-consumer, meaning it stays out of landfills. A PVC roofing system requires a slightly greater investment than that of a TPO roof, but it is also very durable and has a similar lifespan if installed and maintained correctly.

Modified Bitumen

The previous materials are almost exclusively used in industrial and commercial structures, but modified bitumen is perhaps the most common material for residential low slope roofs. It consists of five layers of asphalt that has had modifiers added to it to give it plastic or rubber-like properties. It is installed in large rolls and adhered with heat or with a factory applied self-adhesive. Modified Bitumen is designed to withstand very harsh environmental conditions, which makes it a good option for storm and heat prone areas of the Mid-Atlantic such as southeast Virginia.

Types of Shingle Roofs

Shingle roofs are seen on both commercial and residential structures, as long as the roof has a steep slope. There is a wide variety of shingle materials on the market designed for different purposes, styles and locations.

Asphalt Shingles

This is the most popular type of residential roofing material today. It’s also the most cost effective. Asphalt shingles consist of a fiberglass mat, top and bottom layers of asphalt, and mineral granules. There are three-tab shingles and architectural shingles, the latter being more costly but also more durable. Asphalt shingles are produced in a wide variety of colors to match myriad home styles and designs.

Synthetic Roofing

Whether they’re made to look like cedar shake, slate or any other type of upscale material, synthetic shingles are made with recycled materials and have a lower impact on the environment in part because of their lifespan which can be 40-60 years. These premium roofing systems should only be installed by roofing contractors who are experienced with these materials. They can be expensive, but their extended lifespan makes up for some of the upfront cost.

Wood Shingles & Shakes

Made from cedar, redwood, southern pine and other woods, these shingles are machine sawn or hand hewn. Some local building codes limit the use of wood shingles and shakes because of concerns about fire resistance, but there are certain wood shingle products that incorporate a factory-applied, fire-resistant treatment. These shingles are not often installed on a new structure or total roof replacement, but because of the age of some homes in the Tidewater region, wood shingles are often needed for repairs of older roofs or to maintain the design of a historic home.
