Roof Hatch – All You Need To Know

Most commercial buildings need access to their roof to maintain HVAC or other roof equipment. Even though there are several ways to access the roof area, the most common way is to use the roof hatch. The roof hatch provides direct access to the roof area and is designed with many features and options to ensure safe access for maintenance workers and weather resistant performance for building owners.

Size matters

Roof hatch is available in various sizes. There are many factors that need to be considered when choosing hatching for certain applications. First, determine whether the hatch will be used simply to gain access to a roof or whether it is needed to install or remove equipment from a building.

If a hatch is to be used for personnel access only, small or single-cover models should be specified. These models typically are used with a fixed ladder, ship stair or service (full-size) stair. Roof hatch size is defined by measuring its inside frame opening, and the roof opening should be roughly the same as the hatch size.

Material choice

Another important consideration when selecting a roof hatch is its material. Typically, this decision is based on cost, aesthetics, maintenance considerations and a hatch’s geographic location. Hatches are manufactured in galvanized steel, aluminum, stainless steel and copper.
