What is a roof walk?
A roof walk is a safety system that consists of raised platforms or walkways installed on the roof, providing a safe and stable surface for workers to walk on, ensuring their safety while accessing various parts of the rooftop.
Is a roof walk sometimes called a rooftop catwalk?
Yes, roof walks are sometimes referred to as rooftop catwalks. While both terms can be used, roof walks specifically prioritize safety and stability for accessing rooftops, whereas catwalks may offer broader functions and designs.
What is the difference between roof walk mats and metal roof walkways?
A roof walk mat provides basic protection for occasional work on metal roofs, offering a temporary solution. In contrast, a metal roof walkway offers a long-lasting, safe, and stable platform for regular access and supporting heavier loads across the entire roof.
What are the safety benefits of installing rooftop walkways on metal buildings?
Rooftop walkways offer a safe, anti-slip surface, reducing the risk of slips and falls, especially on sloped roofs. They include guardrails and comply with OSHA regulations, ensuring safe access to roof equipment and surface protection.
How does a standing seam roof walk protect the roof and increase its longevity?
Standing seam roof walkways distribute pedestrian load uniformly, protecting the roof from direct foot traffic damage, thereby extending the roof’s lifespan by preventing wear, tear, and leaks.
