Understanding Our Terminology
Single Slope Roof
A single slope or single pitch roof is a roof that has a single pitch in one direction. They go by many names, including pent roofs, shed roof, lean‐ to roofs, or skillion roofs. They are commonly attached to a house wall or fascia board and supported out front by a support wall or beam and post assembly. We do not offer gable or A-frame roof construction.

3 Season Sunroom

We typically will define a 3 season room as one that will have single pane windows and is not going to be heated or cooled on a permanent basis. Both the Alpha Plus and OMEGA systems can be built with single pane glass windows.

4 Season Sunroom

We typically will define a 4 season room as one that will have at least double pane windows and could be cooled on a permanent basis. Both the Alpha Plus and OMEGA systems can be built with double pane glass windows. ONLY THE OMEGA sunroom system comes with the extra vinyl cladding on the extruded aluminum framing to provide that extra layer of thermal protection making it the ultimate in 4 season comfort.
