Conventional Roof System In a conventional roof system, the insulation is installed under the roof membrane. This is the most common low-slope roof application. The location of the insulation in a conventional roof system poses a few disadvantages. When inspecting, look signs of the following: 1. Membrane aging. When insulation is used directly under the…
Scope of the Commercial Property Inspection Commercial Inspection Standards of Practice When entering into an agreement to inspect a property, it’s common for the inspector to include in the agreement the Standards of Practice that will form the basis for his inspection. Members of CCPIA perform commercial building inspections according to the International Standards of…
Terms You Should Know Thermal conductivity Thermal conductivity is the K-value. It is the measure of a material’s ability to conduct heat. A low K-value indicates that the material does not allow heat energy to easily pass through. According to the National Roofing Contractors Association (NRCA), a material must have a K-value of 0.5 or…
The insulation used in low-slope roof assemblies typically falls into one of the four categories: rigid board insulation; dual-purpose structural deck and insulating planks; lightweight insulating concrete (LWIC); or sprayed polyurethane foam (SPF). Rigid Board Insulation Rigid board insulation is the most common type of insulation used in low-slope commercial roofing. It is made from…

All buildings are capable of having an unlimited physical service life, but not an unlimited economic life. No other building system surpasses roofs as a source of litigation. Roofs may fail for either economic or technical reasons. Economic Reasons for Roof Failure When decisions are made on how to spend money on the construction of…
The complexities involved in adequately designing a roof for optimal long-term performance are reflected by the number of factors that a designer must consider, including: original construction and life-cycle (long-term) costs; energy conservation scheme; value of building’s interior contents; required long-term service life; basic roof components (deck, insulation, membrane, accessories); availability of qualified contractors/workers; environmental…
The following information is a general overview of basic and accessory low-slope roof components, their major design factors, functions, and common failures. The three main components of a low-slope roof are the structural deck, the thermal insulation, and the membrane. Other vital parts of a low-slope roof include the flashing and air retarders, although these…
Low-slope roofs were a late invention in building construction. This was mostly because steep-slope roofs exhibited superior water-shedding properties. Also, before industrialization, much of the manufacturing of goods was done in people’s homes by hand or with basic small machinery, so there wasn’t a need for larger buildings. But as the Industrial Revolution progressed, it…
Cast-iron boilers are often found in residential applications and small commercial installations. These boilers are compact and function exclusively in low-pressure steam or hot-water applications. The physical size of a cast-iron steam boiler can be quite large, with the sections visible, since it has no casing. Cast-iron is basically steel. It has higher levels of…
by Joe Farsetta, Certified Master Inspector® and Certified Commercial Inspector The fuel or gas train is a series of components – some working independently, and others working in tandem with alternate components – that connect the burner of a gas-fired boiler, which help to ensure the commercial steam boiler’s safe operation. Boiler explosions can happen…
