Roof safety systems: protect your people and your compliance standing.
Every rooftop unit that needs servicing puts someone near an edge. OSHA’s walking-working surfaces rule (29 CFR 1910, Subpart D) requires protection for anyone working within reach of an unprotected edge over 4 feet — and the responsibility for rooftop hazards sits with the building owner, not just the trades who visit. We design and install the systems that make your roof a compliant workplace.

What we install.
Rail without a hole
Counterweighted perimeter and skylight rail that installs without a single membrane penetration.
Safe routes, protected membrane
Designated paths that protect the membrane from traffic wear and keep technicians on safe routes.
The way up
Self-closing gates and rail systems at the single most common rooftop fall point: the way up.
Certified tie-off
Engineered, certified tie-off points for work outside guarded zones.
The underestimated hazard
Screens and rails over the most underestimated fall hazard on any commercial roof.
Designated areas
Compliant designated-area setups for low-frequency work zones.
02 · The method
Assessment first, hardware second.
We start with a rooftop hazard assessment: where does anyone actually need to go, how often, and what’s within 15 feet of an edge? The plan protects real work paths rather than blanketing the roof in rail you don’t need — which keeps both the cost and the roof loading sensible.
Every installation is documented for your safety file: locations, load ratings, and inspection schedule.

Within 6 ft: conventional fall protection · 6–15 ft: protection or designated area by frequency · If people go on your roof, the rule applies
03 · Why us
Why roofers should install it.
Safety hardware interacts with the roof.
Ballast loads the membrane, anchors penetrate it, and walkways change drainage paths. Installed wrong, a safety system creates the leaks we spend the rest of our time finding.
Our crews install protection with flashing details done to manufacturer spec — so your warranty survives your compliance program.
04 · Questions
Frequently asked questions.
What owners and facility teams ask about rooftop compliance.
Does OSHA really apply to my maintenance staff going up to check an HVAC unit?
Yes. The 2017 update to OSHA 1910 Subpart D explicitly covers routine rooftop work. Work within 6 feet of an edge requires conventional fall protection; 6 to 15 feet requires protection or a designated area depending on frequency. If people go on your roof, the rule applies to you.
Will guardrail penetrate my roof membrane?
Not necessarily — counterweighted, non-penetrating systems cover most perimeter and skylight applications with zero membrane penetrations. Where engineered anchors are required, we flash every penetration to manufacturer spec and document it.
Can you add safety systems during a roof replacement?
That’s the ideal time — details get integrated into the new system, warranties stay clean, and mobilization is shared. We include a safety assessment in every replacement scope by default.
