Metal Roofing Over Insulation

Both materials make a great physical barrier between the interior building and the metal roof.

Metal roofing over insulation.

Metal roofing is one of the most durable and long lasting roof materials on the market and can easily last for decades. Metal roof insulation is the best way to control condensation temperature and reduce unwanted noise. They are used in commercial and residential structures to protect against weather and other exterior elements. Foam insulation can be used in existing roof structures.

The use of roof hugger systems allows you add blanket rigid and or reflective insulation between the existing and new roofs. By using roof huggers the existing roof can be left in place. Metal roof insulation addresses two major goals. In this case simply lay the insulation between the purlins.

According to the manufacturer s instructions install the metal roofing panels over the insulation. Fiberglass batts or glass mineral wool metal roof insulation the most common material used for an insulating metal roof is fiberglass batts or glass mineral wool. The blanket material is available in various r values and thicknesses. Yes providing a layer of insulation under a metal roof is imperative because metal is naturally a better heat conductor than wood.

This provides a safer environment for both workers inside the building and the roofers as they install the new roof. Roofing insulation blanket consists of a lightweight flexible bulk mineral insulation blanket faced on one side with reflective foil laminate. Due to the configuration of the metal roof panels it is first necessary to install an eps expanded polystyrene insulation in between the metal ribs of the roof panels to create a smooth surface to support the 1 1 2 iso polyisocyanurate roof insulation over which the 60mil white tpo roofing membrane is installed. The batts are located side to side on the rafter of the roof.

Metal roofs are made from steel copper or aluminum panels. Make sure that the insulation you are using is the same thickness so that the metal roof will fit better. Stabilizing the interior temperature and help to prevent material from collecting under the roofing material. Use duct tape to seal the seams and further protect against moisture air leaks.
