Open roof greenhouses give a natural environment for plant growth when the outdoor climate would work and an artificial environment when it is too hot or cool. Opening the roof over the plant life increases light intensity that may help to control the growth habit, flowering and crop timing. It also reduces electrical power costs as expensive fan cooling is not needed.
Several methods are accustomed to open the roof. Some producers make a roof that opens by rolling up the one or double coating of flexible plastic-type material glazing that operates the length of the greenhouse bay. A little gear engine rotates a shaft that 
winds the plastic-type material on to it such as a window color. A light, second framework over the structure secures the plastic-type from bellowing out during windy weather. Opening and closing the roof could be either manual or automatic. Each aspect of the roof could be controlled independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates as they can be tightly closed during cold weather. Most designs use regular vent hardware. Some have panels that hinge at the gutter and open up upward. Opening is nearly 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-type. Some manufacturers give 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 weather. Movable shade is frequently installed with the open up roof design. It decreases the heat load by reflecting the suns rays back out. The shade curtain ought to be of a porous design to allow heat to flee. In northern climates a power blanket may also be installed to reduce 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. Depending on the cropping system, bracing of the structure could be external cables mounted on deadmen, inner compression braces or Gear Motor For Greenhouse trusses with cable X bracing. Flat roof designs are utilized where there is small rainfall or snow. A-roof styles shed the rain and snow to an internal 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 moving the leading edge of the curtain. One equipment motor will deal with up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse due to the single layer plastic-type material and higher infiltration through gaps and cracks in the seals.
