Roof Hatches

Roof hatches create an access point through flat roofs for building maintenance teams and authorized personnel working on commercial properties, warehouses and manufacturing facilities. When selecting a hatch, consider the required opening size, insulation and weather sealing needs, cover operation, roof-membrane installation details, and the level of access control needed for the building.

Choose a Roof Hatch for Practical, Controlled Roof Access

A roof hatch should support the way maintenance personnel enter the roof while helping protect the building opening from weather exposure and unwanted access. Review the opening required for ladder access, then compare operating, sealing, insulation and locking details described for the hatch.

Planning Guide

Plan the right fit before choosing

Plan the Access Opening

Start with the required roof-entry space

Choose a hatch with an opening appropriate for the access method and building use. Representative products include configurations intended to support ladder access and one-handed cover operation, helping the operator maintain three points of contact with a ladder.

  • Confirm the opening dimensions required for the project.
  • Consider how personnel will enter and exit the roof.
  • Review cover configuration and hold-open support.
Protect the Building Envelope

Consider insulation and weather-sealing features

An insulated curb and cover can help reduce energy loss through the roof opening. Door seals, insulation and continuous EPDM gaskets are described as helping retain conditioned air and limit exposure to rain, snow and outside temperatures.

  • Look for insulated curb and cover construction.
  • Review gasket or door-seal details.
  • Consider curb features that help secure roofing membrane and backer rod.
Control Operation and Access

Balance easier opening with controlled entry

Counterbalanced springs, dual compression cylinders and locking hold-open arms can help make cover operation more controlled. For access control, review available interior and exterior handles with padlock hasps or an automatic lock arm.

  • Compare spring-assisted or counterbalanced opening features.
  • Check for a locking hold-open arm.
  • Select locking details appropriate for authorized access.
