A flat (low-slope) roof is a precious thing. Oh, it’s not a jewel or a Tennessee racehorse, but it is both valuable and delicate. Any commercial building owner knows to keep feet off the roof. What flat roof materials can you walk on? What materials hold up best to foot traffic?
These Boots Are Made for Walking
Workers’ boots are often viewed as a commercial roof’s worst enemy. Some third-party vendors must walk on your commercial roof, however, and could include:
- HVAC contractors
- Sign companies
- Window washers
- Radio mast maintenance crews
- Cell phone antenna servicing
Your own facilities crew needs to tread upon the roof to remove debris, inspect the roof, and clear internal drains and parapet scuppers. Tenants may also want to walk on the roof for special occasions or a bit of fresh air.
Best in Show: Which Flat Roofing Materials Can You Walk On?
Several commercial roofing materials are tough enough to withstand foot traffic. Among the best, and among those offered by Rackley Roofing:
- Green Roofing and Pavers — Possibly the best option for a high-traffic low-slope or flat roof, a green roof made from interlocking soil receptacles and pavers is fully walkable
- Built-Up Roofing (BUR) — A BUR or tar-and-gravel roof is designed to take foot traffic thanks to the alternating layers of waterproof reinforcing fabric and bitumen, topped with crushed stone. Please note: Rackley Roofing does not install hot BUR roofing systems.
- Thermoplastic Polyolefin (TPO) — This single-ply system is resistant to tears, impacts, and punctures; its flexibility allows the underlying structure to thermally expand and contract; it is somewhat safe to walk on, though walk pads can reduce wear and tear
- Polyvinyl Chloride (PVC) — Another single-ply system in many ways tougher and more durable than TPO, a PVC roof can easily withstand foot traffic in moderation; it cannot take careless tool strikes
Not So Fast
Of all the roofing options available through Rackley Roofing, we suggest treading lightly with ethylene propylene diene terpolymer (EPDM). EPDM can be walked on lightly during installation and with normal maintenance schedules. When your facilities crew is walking on an EPDM roof, encourage them to walk deliberately (not fast), avoid turning on the balls of their feet (which can stress the rubber), and keep tools secure to prevent punctures and tears.You have commercial roofing questions.
