Commercial Applications for Walkable Roofing Pavers

Many commercial buildings are designed with flat or low slope roofs which are doing one simple thing: keeping the weather out.

Of course, that’s the most important thing for a roof to do, but it’s not the only thing it can do. And in Hampton Roads’ competitive business environment, using every single square foot available can give a business a real leg up.

Walkable roofing pavers can give owners of commercial structures a competitive advantage in a variety of ways. The same system that turns a residential flat roof into a rooftop terrace works just as well or better at commercial scale, where the return on that square footage can be measured in additional revenue, higher occupancy, better tenant retention, or simply a stronger competitive position in the market.

The concept is straightforward: a waterproof TPO membrane goes down first (and is possibly already on a no slope commercial grade roof), followed by a drainage mat, and then durable rubber composite paver squares are set on top. They aren’t permanently adhered, which means individual squares can be lifted, repositioned, or replaced without disturbing the roof below. The result is a stable, attractive, fully walkable surface that protects the roof underneath while turning dead square footage into usable space.

If you want the full technical picture on how the system works, we covered it in an earlier post. Here, we want to talk about what’s possible when commercial property owners start looking up and thinking about their roofs differently.

Restaurants: More Capacity, Same Rent

Expanding a restaurant’s seating capacity is one of the hardest and most expensive moves an operator can make, unless you go up rather than out. A rooftop dining terrace adds seats without adding to the lease footprint, – a nearly impossible thing to accomplish any other way.

In Hampton Roads, where spring and fall offer some of the best outdoor dining weather on the East Coast, a rooftop terrace extends the revenue-generating season well beyond the summer months. A rooftop bar creates its own draw for guests who come specifically for the experience of the space, not just the menu. For restaurants looking to differentiate in a crowded market, the rooftop vibe is hard to replicate.

Keep in mind: commercial restaurant installations require attention to load capacity, drainage, safety railings, and permitting, but these are all navigable with the right contractor and a little lead time in the planning process.

Hotels: High End Amenities

For hotels, amenity space goes beyond function and becomes a true marketing asset in a crowded tourist industry like we have in Virginia Beach. A rooftop terrace will show up in photos, reviews and in the mental checklist travelers run through when choosing where to stay. Boutique and mid-scale properties that can’t compete with large resorts on square footage or ocean frontage can use a rooftop installation to punch well above their weight on a unique experience.

This is particularly true for smaller oceanfront and ocean-block hotels in markets like Virginia Beach. A hotel that sits one or two streets back from the water may have limited or no ocean views from its standard rooms or ground-level common areas. A rooftop terrace changes that, providing a legitimate “ocean view” space on the property, which opens up amenity language and marketing that wasn’t available before.

Beyond the view, rooftop spaces can be booked for private events, corporate gatherings, and weddings, providing a revenue stream without a significant increase to overhead.

Multifamily Residential: One More Reason to Renew a Lease

Apartment buildings and condo developments also compete heavily on amenities, and outdoor communal space is consistently near the top of what prospective tenants and buyers want. For urban infill properties or buildings with limited ground-level common space, the roof is often the only place to create meaningful outdoor space.

A rooftop terrace that’s furnished, landscaped, with seating areas or a grill station is a premium amenity that will stand out in listings. It can also increase tenant retention. When tenants value their building’s amenities or see them being invested in, they are more likely to stay put, which is important since turnover is one of the most expensive things a property manager deals with. Walkable composite pavers are especially well-suited for shared amenity spaces because they require almost no ongoing maintenance. You won’t have to worry about resealing, splinters or rotting boards to replace season after season.

Office Buildings: Out(side) of Office

Employee expectations around office environments and personal wellbeing have shifted dramatically in the last several years. With more workers concerned about work/life balance and having a healthy work environment, whether they’re working from home or at an office, outdoor access during the workday has become a baseline requirement for many people. Building owners competing for commercial tenants are responding accordingly.

A rooftop terrace gives office occupants a place to take calls outside, step away from a desk for lunch, or decompress between meetings in a way that a lobby or break room can’t replicate. For building owners, it’s one more amenity to add to your sales pitch that can have a big influence over modern companies’ leasing decisions. Pavers can also be paired with planters and greenery to create green spaces that feel restorative and functional. Happy employees have higher retention, fewer sick days, and are more productive, which is good for everyone.

Rooftop Gardens: Creating Green Space

Walkable pavers are an excellent foundation for rooftop garden installations such as raised garden beds and green zones. The applications are varied: a restaurant with a rooftop herb or produce garden can use this as both a supply source as well as a marketing story for health and environmentally conscious customers. A corporate campus with rooftop green space creates an amenity that supports employee wellbeing. A multifamily property with community garden plots turns the roof into something tenants actively use and value. The pavers provide the durable, low-maintenance foundation that makes it worth a property owner’s while.

What Commercial Installations Require

Regardless of the application, there are some key fundamentals to make walkable pavers work: structural soundness, proper waterproofing, drainage, and experienced installation. Commercial projects typically require additional considerations like load calculations (typically done by a structural engineer), safety and railing code requirements, and local permitting, so the contractor you choose needs to be equipped to handle the full scope.

The long-term investment case is strong, though. Firestone SkyPavers carry a 20-year warranty with a potential lifespan of up to 50 years, compared to wood or other traditional surface materials that require regular maintenance and eventual replacement.

Put Your Roof to Work

The flat roof on a commercial building doesn’t have to just be an expense. With the right installation, it can become a revenue driver, a tenant amenity, a marketing differentiator, or an employee benefit. If you’re curious about what a rooftop installation could look like for your property, we’d love to talk to you about it.

The Role of Proper Ventilation for Roof Health and Energy Efficiency

When Southeast Virginia summers hit, your roof starts working overtime. But if it’s not breathing right, you could be facing major issues.

Hampton Roads homeowners know summer doesn’t ease in gently. By late May (or even April!), temperatures are climbing into the 90s, humidity is thick, and on a clear, sunny day, your attic temperature can soar past 150°F. Most people only think about their roof when something goes wrong that’s immediately visible – a missing shingle after a storm or stain on the ceiling after a heavy rain, but one of the most damaging things that can happen to a roof in this region is largely invisible until it’s too late: poor ventilation.

Proper roof ventilation isn’t a luxury or an up sell – it’s a foundational part of a healthy roofing system. When ventilation fails, the rest of your home’s structure will feel it, as will your energy bills. Here’s what Southeast Virginia homeowners need to know heading into another hot, humid summer season.

How Proper Roof Ventilation Works

A properly ventilated roof system is simple in principle: fresh air enters through intake vents (typically at the soffits) and hot, moist air exits through exhaust vents (at or near the ridge). This continuous airflow keeps your attic from becoming a heat and moisture trap.

Without adequate ventilation, two major issues will arise:

  • Extreme heat builds up in the attic space during the day, radiating downward into living areas and stressing roofing materials from below.
  • Moisture will occur from condensation, when the warm, humid air from outside meets cooler surfaces inside and is trapped.

Condensation: The Silent Destroyer

In the Tidewater region, condensation is a serious concern. Our region’s climate means we deal with heat and humidity in the summer months and temperature swings in the fall and spring, both of which create prime conditions for moisture to accumulate in an attic.

When warm, humid air gets trapped in a poorly ventilated attic, it condenses on the cooler surfaces of your roof’s structural components, from there the damage can compound quickly.

Your roof decking (typically the sheets of plywood you can see from inside your attic) will be the first material to be affected. Over time, moisture exposure will cause the wood to swell, warp, and eventually rot. Once this happens, it can no longer hold fasteners properly, meaning your shingles aren’t as secure as they should be.

From there, moisture can work its way into the rafters, which bear the weight of your whole roof. As you can imagine, wood rot in rafters is serious and in advanced cases, it leads to a sagging roofline and significant structural repairs.

Finally, your insulation will incur damage. Wet insulation loses its ability to resist heat transfer, packs down and clumps, and becomes a breeding ground for mold. Once it’s moisture-damaged, it typically has to be replaced entirely. And mold itself isn’t just a structural problem; it’s a health concern that requires expensive remediation. The good news is that all of this is preventable with proper ventilation.

The Cost of a Poorly Ventilated Attic

We’ve all been hearing about the rise in energy bills, but there’s one reason for this that may not be top of mind: roofing ventilation.

When your attic reaches 140–160°F on a hot afternoon, which it easily can without proper airflow, that heat radiates directly through your ceiling into your living space. Your air conditioning system then has to work significantly harder to maintain a comfortable temperature. It cycles more frequently, runs longer, and wears out faster.

A properly ventilated attic stays dramatically cooler. Adequate attic ventilation can reduce attic temperatures by 40°F or more on peak summer days. That’s a huge reduction in the work your HVAC system is doing, as well as your monthly bill.

Ventilation is Just One Part of the Puzzle

Ventilation is just one part of a healthy roof system. Shingles, underlayment, decking, insulation, and ventilation – every layer depends on the others to perform as designed. Shingles can be in perfect shape while the decking beneath them quietly rots from trapped moisture. Insulation loses its effectiveness the moment it gets wet. A well-designed ventilation system is what keeps everything else working.

That’s why when we evaluate a roof, we look at the complete picture, not just the outermost layer. A comprehensive inspection includes checking soffit vents for blockages, evaluating ridge vent access, and looking for signs of moisture damage in the decking and framing.

Signs Your Roof May Have a Ventilation Problem

If you’re not sure whether your roof has ventilation issues, here are some warning signs to watch for as we head into the hot months:

  • Your upstairs rooms are noticeably hotter than the rest of the house, even with the AC running
  • Your energy bills spike sharply in summer months
  • You notice a musty smell in your attic or upper floor
  • There are visible staining or dark spots on attic sheathing
  • Your roof shows premature aging such as curling, cupping, or granule loss on shingles that aren’t that old
  • Ice dams formed along your eaves last winter (a telltale sign of uneven attic temperatures caused by poor ventilation)

Don’t Wait Until Summer to Find Out

The best time to address ventilation issues is before the heat arrives. By the time your attic is baking in July and your energy bills are quite literally through the roof, the damage may already have started.

Andrews Roofing serves homeowners across Hampton Roads – from Virginia Beach and Chesapeake to Suffolk, Portsmouth, Norfolk and the surrounding communities. We understand the specific demands our climate places on roofing systems, and we know that a truly healthy roof is one that’s been built and maintained as a complete system.

If it’s been a while since your roof has had a thorough inspection or if you’ve noticed any of the warning signs above, contact us today. We’ll evaluate your roof from shingles to soffit vents and give you a clear, honest picture of where you stand and what will continue to keep your home healthy heading into summer.

TPO or PVC: Which Low-Slope Membrane Is Right for Your Industrial Roof?

For property owners of warehouses, manufacturing facilities, or other industrial structures, the roof of your building isn’t just literal overhead, it’s one of the most critical components of the entire building.

Its success or failure can massively impact operations and profitability. And for the flat or low-slope roofs that dominate industrial construction, the material you choose matters enormously. Two of the most popular options – TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) – are all single-ply membrane systems, which is exactly why they’re so commonly confused. While they may look similar on the surface, they perform differently depending on your building’s environment, purpose and your priorities as a property owner. If you’re having a roof installed or replaced on an industrial structure, here’s what you need to know about these different membrane materials.

TPO (Thermoplastic Polyolefin)

TPO is one of the most widely installed low-slope membrane systems in the country, and for good reason. It’s a single-ply white reflective membrane that’s heat-welded at the seams, creating a watertight bond.

Benefits: TPO’s biggest selling point for industrial clients is its energy efficiency. The white reflective surface deflects UV rays and reduces cooling costs, which is a real advantage for large industrial buildings with significant roof square footage. It holds up well against punctures, tears, and impact, and the heat-welded seams are highly resistant to leaks over time. It’s also one of the more cost-effective options up front, making it a good value for large-scale projects.

Challenges: TPO is a relatively newer material compared to EPDM, so there’s less performance data, and the quality can vary between manufacturers. The key to using TPO is working with a contractor who sources from reputable brands and is familiar with the product.

Best for: Buildings where energy efficiency is a priority with large roof areas that are exposed to sunlight. Projects where budget and performance need to be balanced. It’s an excellent all-around choice for warehouses and distribution centers in climates like Hampton Roads where summer heat is a real factor.

PVC (Polyvinyl Chloride)

Like TPO, PVC membranes have a white reflective surface and heat-welded seams, but they offer the additional advantage of being chemical resistant. PVC has been used in industrial roofing since the 1960s and continues to be a popular option because of its performance in specific demanding environments.

Benefits: PVC’s resistance to chemicals, grease, animal fats, and industrial oils sets it apart from TPO. The heat-welded seams are as strong as TPO’s and like TPO, the white reflective surface helps manage heat and energy usage. PVC is also highly fire-resistant, which matters a lot in certain industrial settings.

Challenges: PVC carries a higher price point than TPO. Due to its formula, certain chemicals can leach out of the membrane over time, which will often cause it to become brittle if it’s not a high quality product. It can also be more sensitive to certain adhesives and solvents during installation.

Best for: Food processing facilities, restaurants, manufacturing plants that handle oils or chemicals, and any industrial application where roof exposure to chemical runoff or grease-laden exhaust is a real possibility. If your facility vents cooking oils, industrial solvents, or other chemical byproducts anywhere near the roof, PVC should be at the top of your list.

So How Do You Choose?

The honest answer both are good, solid systems when properly installed. The right choice depends on your specific building and how it’s used.

  • Choose TPO when energy efficiency, budget, and general performance are your priorities.
  • Choose PVC when your facility is exposed to chemicals, grease, or industrial byproducts that would compromise other membrane materials.

Understanding Roofing Crickets and When to Use Membrane vs. Shingles

At first glance, a roof may look like a simple series of slopes and shingles, but in reality, good roofing is a careful blend of structure, materials, and strategy—especially when it comes to managing water flow. One critical but under-appreciated element in certain roof designs is the roofing cricket.

What Is a Roofing Cricket?

A roofing cricket—sometimes called a saddle—is a small, peaked structure installed on the high side of a roof penetration such as a chimney, wall, or dormer. Its job is to divert water around these vertical elements and prevent it from pooling, which can lead to leaks, rot, or premature roof failure.

You’ll typically find crickets in low-slope areas or where two roof slopes intersect to form a valley. Without a cricket, water tends to gather and sit—especially during heavy rain which we are prone to in Southeast Virginia—leading to drainage problems and long-term damage.

How Crickets Work

Crickets redirect water using gravity. By adding a subtle peak to the backside of a chimney or at the base of a wall intersection, water is forced to flow down either side of the obstruction rather than gathering behind it. This keeps your roof drier and increases its longevity.

In these photos from a recently completed project in Suffolk, you can see two examples of cricket installations. Each cricket helps manage the directional flow of water and is customized to fit the slope of that particular roofline.

Membrane vs. Shingles: Choosing the Right Material

In most residential roofing, asphalt shingles are the go-to material due to their cost-effectiveness and ease of installation. However, they aren’t ideal in every situation—especially when it comes to areas with very low slopes, also present on this roof that required crickets.

Roofing membranes are single-ply materials (typically rubber or synthetic) designed to be fully waterproof. They’re most commonly used on flat or low-slope areas of a roof where shingles would fail to shed water effectively. It is a material that is often used on commercial buildings, but less often used on residential homes. Their cost can be a little higher than shingles, but their performance in specific areas makes them a necessary investment in certain situations.

In this recent project, we encountered two cricket areas that were previously covered with membrane. Our team made material choices based on pitch and performance needs and determined that in one area with a low pitch, we should reinstall membrane because the slope required a fully waterproof solution to prevent ponding and leaks. In the second area, although membrane had been used previously, the steepness of the slope allowed for us to use shingles instead, saving the homeowner on cost without compromising performance.

What Homeowners Should Know

If your roof includes valleys, dormers, or chimneys, especially if your home has a complex roof layout, it’s worth asking your roofer whether crickets are needed. These small features can make a big difference in preventing leaks and prolonging the life of your roof.

Also, be aware that not all areas of your roof should be treated the same. Experienced roofers assess each slope and intersection to determine whether shingles are sufficient or if membrane is a better long-term solution. A one-size-fits-all approach simply doesn’t work when it comes to effective roofing.

Signs Your Metal Roof Might Need Attention

Metal roofs are well known for being incredibly durable and long-lasting, often boasting lifespans of 50 or more years.

However, in regions such as Hampton Roads where severe weather and salt air are plentiful, metal roofs can still experience issues over time. While having a metal roof installed should give you some long-term peace of mind, there are still things you should keep an eye out for that may indicate it’s time for a repair or replacement. Fortunately, if you’ve had your metal roof installed by professionals to the manufacturer’s specifications, you should have a robust warranty in place that may cover the material and even the labor cost.

Here are some common problems that can occur with metal roofs and warning signs that indicate potential repair or replacement:

Leaks

Of course, like all roofs, an obvious leak is a sure sign that your roof needs attention. Look for water stains on the ceiling or walls, damp insulation in your attic and dripping water. On a metal roof, leaks are most likely to come from damaged or missing flashing, loose seams, or holes caused by corrosion or impacts.

Corrosion

Standard metal roofs can corrode over time, especially in areas like southeast Virginia with high humidity and exposure to salt air. That’s why proper metal roof material should be used near salt water. However, if the proper materials were not used and corrosion does occur, the signs will include rust spots, pitting, or flaking paint. In many cases, issues such as these are covered by the manufacturer’s warranty, so make sure to keep your paperwork and information on your roof in a safe place that you can easily access.

Loose Fasteners

Fasteners holding the metal panels in place can become loose over time due to thermal expansion and contraction or inadequate installation. Loose fasteners may cause panels to lift or shift, leading to leaks or structural issues. Fortunately, this is a relatively easy fix by a roofing professional that may also be covered under a warranty. While it’s a simple fix, it is also a very necessary one that should be taken care of as soon as the issue is identified.

Ponding Water

Improper installation or poor roof slope can result in water pooling on the roof surface, which can accelerate corrosion and lead to leaks. Ponding water may also indicate inadequate drainage systems. If installed by an experienced roofing contractor, issues like this should be avoided, but settling in the foundation of a home or damage to gutters or drainage systems may also have occurred since the roof installation, so call in a professional to inspect the issue and provide a long-term solution.

Dents and Damage

Metal roofs can sustain dents from hail, falling branches, or other impacts caused by severe weather. While small dents may not immediately affect the roof’s performance, larger dents or widespread damage may require repair or replacement before corrosion sets in. In some cases, an insurance claim may be necessary to cover the costs of these types of damages.

Andrews Roofing Can Help

If you notice any of these warning signs or suspect that your metal roof may have issues, it’s essential to have it inspected by a qualified roofing professional. Early detection and prompt repairs can help prevent further damage and extend the lifespan of your roof. Andrews Roofing is experienced and highly qualified to inspect, repair and replace metal roofing systems. Contact us today for more information.
