Roof Cooling System

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.

Roof cooling system.

This cooling reverses the heat flow through the roof. While a sunlight absorbing black roof can reach up to 190 f in the summer a reflective roof s temperature can be as much as 60 f lower reducing heat flow through the roof system. The water evaporates and cools the surface. Rooftop gardens shade the buildings below from direct sunlight and reduce both surface.

One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. Since 1981 sprinkool systems international inc. This effect creates an effect equivalent of r 7 roof insulation during the day. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.

They are simple and appear to be effective but would not be a good choice in areas where water is in short supply.

Base roof cooling kit includes.

A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products. Roof cooling works by removing heat energy from the roof and by blocking the invasion of the sun s infrared rays from penetrating the roof and heating the building s mass inventory and personnel. A cool roof reflects the sun s energy reducing rooftop temperatures. Heat is now transferred out of the building through the roof.

Ballasted roofing systems are roofs in which a membrane is laid on the roof deck and held in place by the. The heat load through the roof is normally overlooked but its contribution to a building s total heat problem can be a significant factor. Has been designing and manufacturing component packages for passive roof mist cooling systems for commercial and industrial facilities sprinkool system trailer bay units truckool system and residential buildings hydrokool system. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
