The term roof-top system refers to the roof system, which is typically comprised of flat or slatted surface and a number of support members such as the rafters, cleats, ladders and tiebacks. The rafters are typically made from materials which are capable of providing the necessary strength to hold up the roof system and provide structure for the framing members. Other components of the roofing system may include the horizontal safety beams and systems, cleats, tiebacks and ladders. Roof-tops are generally placed above the ground and are secured in place using steel I beams and cleats.
Roof-tops can also be equipped with automatic devices such as the rain sensing device, the dual flap system and the double rollers. These devices can detect moisture and provide warning of impending rain before it arrives. The dual flap system allows for an increased level of security by incorporating a second safety railing system with the same safety features available on the single-flap system. The single rollers are designed to prevent birds and insects landing on the roof-tops and to allow gradual and continuous movement of the roof.
Another vital component of the roof is the metal roof skylights. Roof skylights provide daylight heating and cooling, as well as ventilation. When selecting a rooftop guardrail, it is important that the manufacturer provides complete information regarding the type of venting system required and that these venting systems comply with all applicable codes. In addition, skylights provide ventilation by opening partially or completely and thereby allowing warm or cool air exchange. It is important that skylights maintain an appropriate draft to prevent heat loss and reduce energy consumption during the winter months. Proper venting and adequate insulation are two other important components of the skylight system.
Other necessary accessories for a safe and functional roof are flashing and guttering. Flashing is generally used to provide elements such as protection from wind and sun during the early stages of construction. Guttering is used to keep rainwater and snow out of the house. It is important to note that guttering does not provide elements that require a connection to the house, such as a roof edge railing system, until the prefabricated or pre-installed metal roof system is installed.
A final component of a safe roof system is the weight counterbalance. The weight counterbalance prevents the roof from tipping over in the event of high winds or heavy rains. There are basically three types of weight counterbalances: motorized, battery-powered and manual counterbalance. Each system provides different strength and load distribution, as well as maximum square footage capacity.
The safety rail systems provide numerous applications in commercial and residential buildings. In addition to providing elements such as protection from wind and rain, they also provide elements such as guardrails and gutter guards. Some come with added features such as automatic gate opening, adjustable gutter opening, weather stripping, and adjustable cable runs. Such an accessory may also come with an electrical ground conductor, so the guard rail system can be electrically operated.
