One of our customers had a unique situation on the roof they were working on. The roof had an existing fall protection railing, but it was old, rusted and probably no longer OSHA compliant (see this post about inspecting guardrail). Instead of tearing out the old system completely they decided to refurbish the railing by painting the existing uprights and adding new corrosion resistant aluminum rails to the fall protection railing with Kee Lite aluminum pipe railing fittings.
This option was the best option for this company because the railing was already penetrating the roof membrane. Taking out the existing roof railing would have meant a lot of additional roof patching (can you say expensive).
The situation that this company found themselves in is one of the primary reasons why we recommend KeeGuard non-penetrating rooftop guardrail for rooftop fall protection. The KeeGuard system uses weight and counterbalances, and does not penetrate the roof membrane. The KeeGuard system is also galvanized to prevent corrosion.
Whatever situation you find on your rooftop, we can help you protect the people who work there. Please contact us and we'll be happy to talk with you about your fall protection needs.
