Test Methods For Roof Top Supports

Poorly designed structural supports for rooftop units can cause major roof system damage.

Test methods for roof top supports. Spray testing flood testing capacitance impedance testing nuclear metering and infrared ir thermal imaging. H stands for pipe support duct support.

Historically there have been five widely used testing methods for testing of horizontal membranes. This method works due to the ability of water to store or conduct electrical energy. Traditional support methods can lead to poor management of excessive dead weight causing equipment to penetrate the roofing system. A new astm international test method aims to prevent air leakage in and around roofs helping improve energy efficiency reduce moisture problems and prevent pollutants from entering a building.

It is critical that each assembly of the building envelope be investigated for air leakage performance with appropriate standards says astm member sudhakar molleti. Whenever possible use methods to clear ice and snow without workers going on the roof. The procedure involves placing a hand held moisture meter on the surface of the roof which sends an electrical current into the roof without penetrating its membrane. 4 1 the test methods described herein are intended to provide a basis for relative comparison of roof coverings.

The rooftop strut support shall provide a fixed height mounting platform with a minimum of 4 or 6 off of the roof and a usable strut length of up to 6 10 16 24 30 36 42 48 or 60. Staff can climb up ladders to apply de icing materials or use snow rakes or drag lines from the ground.
