Flat Roof Sloped Insulation

Creating a positive slope roof is traditionally done by installing rigid board insulation such as xps or polyiso on flat or low sloped roofs.

Flat roof sloped insulation. Insulation is placed in between the joists underneath the roof surface above. There is a problem with using these materials though. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system. Insulation material is placed on top of the roof rather than in between the ceiling and the decking.

Dual purpose structural deck and insulating planks. Perfect for flat or low sloped roofs. The insulation used in low slope roof assemblies typically falls into one of the four categories. For a 1 inch board equivalent of 6 r value.

While expensive the best insulation is polyiso rigid foam. Since the piece of iso is 4 long the thickness increase will be equal to 1 4 times 4 or a rise of 1 over the 4 distance 1 2 to 1 12 flat roofers can then arrange the sloped insulation to move water towards roof drains scuppers or gutters. This tapered roof insulation technology creates high thermal performance which improves interior comfort and reduces the energy costs of keeping a building comfortable. It is top quality and the most cost effective product for your flat roof.

Under a flat or low slope roof the usual rules about roof insulation and ventilation don t apply. We can be the perfect solution just call us. We recommend having at least 20 r value worth of material for optimal energy efficiency. Sprayed polyurethane foam spf.

Lightweight insulating concrete lwic. Foam control plus and foam control tapered roof insulation also offers optimum design flexibility for the architect and saves the roofer applicator time and labor. Two basic approaches to insulating flat roofs this article explains methods for avoiding moisture condensation problems in compact insulated roofs that have no roof cavity space and in steel or wood framed roofs that have a roof cavity space and that usually include insulation within the cavity space. You can expect to pay about 55 100 sq ft.

Energyguard tapered polyiso insulation provides a logical and economical answer for roofs that do not permit adequate positive drainage like low slope roofs. There are two main types of flat roof that require different approaches to installation.
