Methods For Making A Waterproof Roof Hatch?

To install a roof access hatch, cut a piece of fiberglass or rigid foam board insulation the same size as the attic hatch and nail or glue it to the back. If you have pull-down attic stairs or an attic door, weatherstrip the edges and put a piece of rigid foam board insulation on the back of the door. Surespan manufactures and supplies thermally broken roof hatches in a range of standard sizes and bespoke.

Professional roof access hatches provide the safest way of accessing flat roofs. The manhole (access hatch) to your roof space is a source of draughts, with hot air coming into your home in Summer and warm air leaving your home in Winter. To fit a glazed roof access hatch with a PVC kerb onto a flat roof, install the hatch over the long side at a pitch of 5° to minimize dirt build-up on the lid/glass.

A wide range of hatches exist for different weight ratings and use cases. Explore key factors like material, latching systems, and dimensions to help you select the ideal roof. Flashing a roof hatch on a built-up roof using the hot application method ensures a watertight seal and long-lasting protection for your property.

Seal the attic hatch or door with self-sticking weather stripping and add 2-1/2 inch wide stops if the hatch rests directly on the moldings. Staka roof access hatches are waterproofed and made airtight using a high-quality rubber sealing between the upstand and the hinged lid. Broadcast roofing mineral (fine aggregate) over the hatch while still wet to prevent cracks.

Glue in the roof access hatch using roofing material and attach it as far as the top of the water trap of the upstand. Gorter offers a safe solution for accessing a flat roof, allowing easy integration in existing or new roofs without affecting the structure.
