36" x 30" BA-RFRH-A Retro-Fit Roof Hatch in Mill-Finish Aluminum

The 36" x 30" BA-RFRH-A Retro-Fit Roof Hatch in Mill Finish Aluminum is a lightweight, low-profile retrofit roof hatch designed to cap directly over an existing roof curb without tearing out flashing or re-roofing.

Built to resist corrosion and hold up long-term, this hatch uses 11-gauge aluminum construction with an 18-gauge inner liner for added strength. 1" polyisocyanurate insulation cuts thermal transfer, while the EPDM seal keeps water out and the envelope weathertight.

Ranging from 60 to 105 lbs depending on size, the welded cover supports a 40 psf live load, while the latch holds it closed against 20 psf wind uplift.

Why Choose 36" x 30" BA-RFRH-A Retro-Fit Roof Hatch in Mill Finish Aluminum?

• No Re-Roofing Needed: An integrated counterflash frame caps existing curbs and secures internally with supplied zinc-plated anchor tabs and self-tapping screws; saving the time and cost of tearing into the roof.
• 50% Lighter Construction: At 60 to 105 lbs, this 11-gauge aluminum build is roughly half the weight of its steel variant, making rooftop handling and installation faster and safer.
• Thermal Protection (R-6): 1" polyisocyanurate insulation in both curb and cover cuts energy loss year-round, backed by a continuous EPDM sponge rubber gasket.
• Weatherproof Seal: A continuous EPDM gasket keeps moisture out around the cover perimeter, protecting the envelope below from weather elements.
• Safe One-Handed Operation: A spring-assist and automatic hold-open arm with a red vinyl grip supports one-handed operation from a ladder.
• Secure Slam Latch: A slam latch with inside and outside handles and padlock hasps secures the hatch.

What to Know About Rough Opening and Installation Requirements?

Required Roof Opening

The BA-RFRH-A is set onto a roof curb opening sized per the submittal drawing for your specified dimensions. Confirm the opening, roof buildup, and flashing details with your design team before installation.

Installation Notes

• Measure the existing roof curb as W × L, with L representing the hinged side.
• Confirm custom dimensions fall within the 24" x 24" min to 48" x 54" max.
• Remove the existing damaged hatch door while leaving the current flashed roof curb intact.
• Lower the BA-RFRH-A aluminum frame over the existing curb.
• Fasten internally using supplied zinc-plated anchor tabs and 1/4-20 x 3/4" self-tapping screws driven into the inside of the existing curb.
• Ensure continuous EPDM gasket forms a complete weather seal

For fall-protection and rooftop-access requirements, review the OSHA walking-working surfaces standard and confirm details with your design team.

Frequently Asked Questions About the Mill-Finish Aluminum Retro-Fit Roof Hatch

What is the weight advantage of the aluminum BA-RFRH-A?

Weighing between 60 and 105 lbs (depending on size), the aluminum model is approximately 50% lighter than equivalent 14-gauge steel hatches (115 to 195 lbs). The lower unit weight simplifies rooftop transport and handling.

Why choose aluminum over steel?

Aluminum keeps the unit lightweight for easier handling and offers strong corrosion resistance, which suits many rooftop environments.

Does insulation help with energy costs?

Yes. Polyisocyanurate insulation (R-6) in both the curb and cover reduces thermal transfer, helping lower building energy costs.

Is it easy to operate from a ladder?

A spring assist and automatic hold-open arm with a red vinyl grip support safe one-handed operation while climbing.

How does the hatch attach to the old curb?

It mounts over the existing frame and fastens through the interior curb walls using included zinc-plated steel anchor tabs and 1/4-20 x 3/4" Phillips self-tapping screws.
