Two of the most common types of roofing construction techniques include stick frame roofs and trussed roofs. Stick framing uses fewer materials and goes faster, but also offers less strength and is not suitable for heavy exterior materials like slate or clay tiles. Trussed roofing systems have rails between their joists that help to distribute the weight of hefty tiles and can, therefore, be used with any kind of exterior covering. When it comes time for Bergen County roofing professionals to insulate a truss style roof, there are a few things that homeowners should be aware of.
The first consideration is knowing when to insulate a roof's trusses. Houses located in climates that have cold and snowy or wet winters benefit considerably from insulated trusses. This is because the insulation helps to protect the wood and the rest of the roofing system from excessive humidity and exposure to extreme temperatures. Insulating the trusses also helps them to maintain strength so that they can hold up those slate tiles for their expected 100 year lifespan.
Property owners also need to keep in mind that insulating trusses is more complex and time consuming than insulating the underside of a roof with just basic framing. It is always a good idea to use roofers who are experienced with this kind of complex and detailed roofing system do the installation.

Roofers will begin by laying rolled insulation along the roof's eaves. Instead of pushing it in, it will serve as a baffle against the blown in insulation that will be installed last. Next, the roofers will block around any recessed lights by cutting a doughnut shaped circle out of the rolled insulation and centering the opening of the circle around the light fixture. This blocks the blown insulation from getting too close to the fixtures. Vent openings and any heat ducts will be blocked with scrap plywood.
The roofers will then use their professional grade blowers to blow in the loose fill insulation around the trusses. As the machine blows, the roofers move its hose in back and forth motions to evenly distribute the fibers. The workers begin at the attic's perimeter and work their way toward the attic access door. A piece of batt insulation will be used to cover the top of the attic's door so that the homeowner and roofers can get in and out without disturbing the loose fill. The temporary baffles and vent blockers will be removed once the desired depth of blown in insulation is achieved.
