Open roof greenhouses give a natural environment for plant growth when the outdoor weather is suitable and an artificial environment when it is too hot or cold. Starting the roof over the plants increases light intensity which can help control the growth habit, flowering and crop timing. It also reduces electricity costs as expensive fan cooling is not needed.
Several methods are used to open up the roof. Some manufacturers make a roof that opens by rolling up the one or double coating of flexible plastic material glazing that runs the space of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic material on to it just like a window shade. A light, second 
framework over the structure secures the plastic-type material from bellowing out during windy weather conditions. Starting and closing the roof could be either manual or automatic. Each aspect of the roof can be managed independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly closed during cold weather. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open upward. Opening is almost 100%. Others possess panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is about 85%. Most designs make use of rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic-type material. Some manufacturers provide a movable gutter to collect rainwater when the roof can be partially open up. Wind sensors ought to be installed to close the roof in stormy weather. Movable shade is generally installed with the open up roof design. It decreases heat load by reflecting the suns rays back out. The shade curtain ought to be of a porous style to allow heat to escape. In northern climates an energy blanket may also be installed to lessen heat loss during the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping system, bracing of the structure can be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof styles are used where there is small rainfall or snow. A-roof styles shed the rain and snow to an interior gutter system. Styles that may carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. The roof opens in sections by shifting the industry leading of the curtain. One equipment motor will handle up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse due to the single layer plastic material and greater infiltration through gaps and cracks in the seals.
