Lightweight Aluminum Roof Hatches

The MEZZ-Series RHA (roof hatch aluminum) roof hatch is manufactured from aluminum to ensure years of dependable use, even in most extreme weather conditions. Aluminum roof hatches are lighter than galvanized roof hatches and offer superior corrosion resistance, making them great for coastal areas or for larger roof hatch sizes. The roof scuttle covers are mounted on a 12" curb with cap flashing to ensure against leakage. Mezz roof hatches come standard with compression springs, zinc plated steel hardware, and 1" insulation in the cover and in the curb.

All MEZZ series hatches have the following available options: custom roof hatch sizes, stainless steel hardware, pitch corrected roof hatch curbs, curb mounted options for mounting to existing roof curb, double wall roof hatch curbs for concrete mount, extra tall curbs for special applications, thicker insulation for roof hatch curbs and lids, hurricane strength version for Miami-Dade county applications with increased wind uplift ratings, Security series available for banks, prisons etc. If there is a custom need you have that is not listed here please give us a call.
