Buying Guide

Match opening dimensions

Measure the interior opening (height and width) and choose a skylight sized to that opening to avoid cutting or adapters

Check outer flange size

Confirm the outer flange or outer dome dimensions fit your roof cutout and overlap for a proper seal and flashing

Prioritize dome material

Choose UV-stable acrylic or polycarbonate domes for weather resistance and long-term clarity in sun-exposed roofs

Evaluate mounting style

Decide between replacement outer domes for existing frames or full-frame units if you need to change the entire installation method

Consider ventilation and compatibility

If replacing a vented assembly, confirm the unit's compatibility with existing screen, shade, or fan components
