Roof Equipment Curbs

What Are Roof Equipment Curbs?

Roof equipment curbs are supports that are installed in roofing systems around openings. The openings in roofs include areas where vents, chimneys or fan HVAC (heating, ventilation, air conditioning) systems are located. A wide variety of roof equipment curbs are available to help protect roofs in these sensitive areas, since the openings that accommodate these systems create exposed seams in the roof. The curbs installed in the roof are able to provide a barrier between the shingles and the other roofing systems, protecting the seam from water and other corrosion. The overall result is a stronger and sturdier roof that has less of a likelihood of deteriorating quickly at the seams. Different types of roof equipment curbs include sound-absorbing, vented, ridged, pitched, canted, straight-sided, and flanged.

What Components Are In Roof Equipment Curbs?

Most roof equipment curbs are made of galvanized steel or aluminum. The body of the curb is formed in such a way that it is a single structure welded only in one section. This helps to ensure that the curb is strong and sturdy. Many roof curbs also contain ridged fiberglass insulation. The insulation is inside the curb, contained by a tray that prevents exposure. Different thicknesses of insulation are also available to meet the needs of various situations. Lap joints are also added to many roof curbs to ensure their strength.

Other optional components of roof equipment curbs can be added depending on the features appropriate for each situation. Damper trays can be added underneath the curb system, which can be fastened in place through flanges. Curb seals are also available, which are rubber seals that can be added to the penning between a fan and a curb cap. If a roof curb is being installed around a fan or ventilation system opening, this seal will help the fan to run properly without exerting high levels of vibration on the ductwork. Double shells could be added to roof equipment curbs to act as a liner over the layer of insulation. If an airstream should not come in contact with insulation, this can be installed.

Coatings are available for roof curbs that provide protection from the outdoor elements. These coatings are available in different colors and can be matched to the roof style. If building or business owners are more interested in a different kind of protection, security bars can also be added to roof equipment curbs. These security bars prevent anyone or anything from entering the system from the ventilation opening.

Beyond the different components that can be added to roof equipment curbs, other models of roof curbs are generally available for roofs with different styles. Flat roofs, pitched roofs, insulated roofs, metal roofs, and shingled roofs all come with their own sets of requirements. Each of these roof styles needs the same protection from the elements, especially around the seams where these ventilation systems are installed. Fortunately, roof equipment curbs exist to meet the needs of each of these situations.
