Rooftop Walkway Systems Meet Safety Needs

First, how are these systems usually designed? A rooftop walkway system serves a few important functions. It simultaneously protects a roof from foot traffic damage and protects workers or employees from slips, trips and falls by giving then a sturdy way to access rooftop equipment. Often there are certain safety features included: non-skid grading, safety handrail (if required), and toeboards. Depending on the roof type, whether a standing seam metal roof or R-Panel metal roof, different installation techniques will be required.
So, when are certain safety features, like a handrail, required? OSHA requires railings if you’re within 10 feet of the roof edge. Railings are also a good idea if you’re on a higher pitched roof system (2:12 to 6:12 roof pitches). Make sure that your rooftop walkway supplier can provide proof that their railings have been independently tested to meet or exceed the OSHA 200-pound lateral load testing standards. Don’t forget to find out if this is required on your project.
The components that make up the system can be made from a variety of materials. These materials include galvanized steel, Galvalume, aluminum and stainless steel. Galvanized steel construction is the most common material used for walkway grating. It’s strong, durable and corrosion resistant. By some estimations it can provide 50 to 70 years of corrosion protection and beyond.
Upon installation there are certain factors to consider. What is the roof panel you’re dealing with? Many metal buildings use standing seam roofs. You will want to use non-penetrating seam clamps to avoid damaging the rooftop or voiding any roof warranty. The style of clamp needed will vary based on the manufacturer and the profile of the roof panel.
Another factor to consider is the pitch of the roof. Often, it’s possible to pitch correct the walkway system so that it runs level. You will want to speak with any supplier prior to specifying a walkway to check whether the system can be pitched corrected and to what degree. Other questions to consider include: What kind of warranty is included with the system? Can PE stamped drawings be provided? Some companies can provide PE stamped drawings for all 50 states.
Taking the time to consider these factors when specifying a rooftop walkway system will help to ensure a successful project from beginning to end. More than that, you can be confident that whoever must step foot onto that rooftop will be able to do so safely and securely.
