Open roof greenhouses provide a natural environment for plant growth when the outdoor climate would work and an artificial environment when it’s too hot or chilly. Starting the roof over the vegetation increases light intensity that may help to control the development habit, flowering and crop timing. In addition, it reduces electricity costs as expensive enthusiast cooling is not needed.
Several methods are used to open the roof. Some manufacturers make a roof that opens by rolling up the solitary or double layer of flexible plastic glazing that runs the distance of the greenhouse bay. A small gear electric 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 from bellowing out during windy weather. Starting and closing the roof could be either manual or automatic. Each part of the roof can be managed independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates because they can be tightly shut during cold weather. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open up 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 use rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic. Some manufacturers provide a movable gutter to gather rainwater when the roof is definitely partially open. Wind sensors should be set up to close the roof in stormy climate. Movable shade is generally installed with the open roof design. It decreases the heat load by reflecting the suns rays back again 
out. The shade curtain should be of a porous style to allow heat to flee. In northern climates a power blanket may also be installed to reduce heat loss during the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. With respect to the cropping system, bracing of the structure could be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof styles are utilized where there is small rain or snow. A-roof designs shed the rain and snow to an internal gutter system. Designs that will 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 difficult than in a typical greenhouse because of the single layer plastic-type and better infiltration through gaps and cracks in the seals.
