Things You Need To Know About Roof Access Hatches

Picking out roof access hatches for residential, commercial or industrial structures requires more thought and know-how than many people realise. While the hardware serves the same basic purpose no matter what type of structure is involved, size, material and installation considerations must be taken into account when selecting hatches to ensure the best possible fit.

Roof access hatches are inserts that go into a building’s uppermost ceiling structure. They provide the ability for people to easily gain access to the roof when necessary while serving as a watertight barrier when not in use. They are often used to provide fast access to HVAC machinery and other mechanical equipment that might be stored on a commercial or industrial building’s roof. In some cases, they are added to homes and multifamily residential buildings to help transform flat roof areas into recreational spaces. They are also used to provide roof access in the event of a necessary evacuation.

When selecting roof access hatches, these considerations are important to keep in mind:

The apparent size requirements – Roof access hatches are available in a wide selection of sizes meant to accommodate different needs. Smaller hatches, for example, may only be suitable for allowing a single person access to a roof at a time without much room to spare. Larger hatches may be more suitable when installation is required for maintenance or recreational needs.

The materials required – Aluminium alloy roof hatches are favoured for use in many applications. This material is known to provide strength and durability while limiting the need for maintenance. Aluminium is also favoured because it does not rust or corrode when cared for properly and can be recycled after use. Galvanised steel roof access hatches, however, may be required if materials used must be fire-rated. Since aluminium may melt under intense heat, steel doors are considered a must when roof access hatches are being installed for emergency use or should local or state building codes demand their use.

Whether a safety railing is needed – Roof access hatches may also come equipped with a safety railing to help people make the final ascent onto the roof. This additional feature may not be a necessity when installation is meant to provide roof access for routine maintenance. When a hatch is installed for evacuation purposes, however, the additional feature may prove very beneficial for safeguarding people.

The installation requirements – It is important to keep in mind roof access hatches must be carefully installed to ensure structural integrity and a watertight fit. When selecting hatches, be sure to understand installation requirements and materials required. Since, the roof will need to be breached during installation, it may be best to contact a professional to perform the work.

Roof access hatches are not one-size-fits-all purchases. When selecting, be sure to understand desired use, building codes, size needs and installation requirements.
