Where Can the NovaTuff Coatings Epoxy Roof Coating System Be Used?
A built up roof (BUR) is comprised of layers of reinforcing felt between asphalt or tar. The asphalt or coal tar is heated and liquified in a container and, then, mopped or applied with a mechanical spreader onto the substrate. If the asphalt is overheated, blistering and slipping between the felt sheets occurs, causing the roof system to age more rapidly.
As it ages and spot repairs are made, most built up roofs will begin alligatoring, referring to the formation of a network of fine cracks across
One of the main problems facing building owners with a concrete roof is the material’s porous nature and tendency to crack. These cracks, micro-fissures and imperfections form on the surface and allow water to seep into the slab, which lead to leaks and can cause corrosion of the rebar that reinforces your concrete roof. In addition to leaks that damage the contents of the building, the structural integrity will be compromised over time if not taken care of.
IsoBoard is a foam (Extruded Polystyrene) insulation board commonly used in new construction. These are then covered with DensDeck. The new substrate is then coated with a roof system, like a single-ply membrane or modified bitumen.
However, the same problems that are posed by any system with a series of mechanically fastened or adhered seams can crop up with these.
There are two main types of metal roofs: commercial (which includes R-panel, Corrugated, and Standing Seam) and historic. All metal roofs expand and contract as the substrate heats or cools, causing strain where the overlapped metal sheets are fastened. Eventually, the seams, overlaps and fasteners will begin to pull away from each other, allowing moisture to penetrate beneath the roof.
Polyurethane spray foam roofs are sometimes referred to as spray on roofs has been used for over 30 years. Spray foam roofing insulation is used primarily on commercial buildings. However, in some regions of the United States, homes with low-slope or flat roofs can use SPF to improve the home’s air seal and lower heating and cooling energy usage. Foam roofing is lighter than tar gravel roofs and Sprayed Polyurethane Foam Roofs have no seams or joints.
Single-Ply Roof refers to a number of roofing systems in which the principal covering is a single layer of flexible membrane, generally sold in rolls. A single-ply roof’s membrane is usually a thermoset or thermostatic substance, such as EPDM, PVC and TPO. The sheets are then rolled across the surface of the roof, and a hot-air welder is used to adhere the seams.
