Many homes built before the mid 1980s were constructed with the use of asbestos based materials. Asbestos was widely used because of its low cost and high resistance to heat and flames. Shingles were one of the most common places that asbestos was used in home construction. It can also be found in ceiling insulation and around pipes. Knowing how to identify the presence of asbestos around the house can help homeowners know when to contact an experienced Norwalk roofing service for proper removal and disposal of these hazardous items.

One of the easiest ways to determine the material of the roof's asphalt shingles is find out when the shingles were installed. If the roofing materials date back to 1986 or earlier, they could include asbestos. The homeowner can use a pair of binoculars to look for signs of wear and tear as roofs of this era will be showing their age.

Asbestos fibers were most often used within asphalt shingles. This is because asphalt on its own has a low resistance to heat and fire. The addition of the asbestos fibers enhanced the resistance and helped the shingles last longer when exposed to the sun's intense heat. Other materials within the roofing system could also have asbestos, including the home's flashing, roofing felt, underlay and the adhesives holding all these layers into place.

Less commonly, cement based shingles may contain a mix of asbestos fibers. The fibers were added as part of the aggregate to strengthen the shingles and increase their ability to resist the spread of fire. In addition to the possibility of finding these shingles on the rooftop of a house, they may also be found on a property's out buildings, including garden sheds, tool sheds and barns.

Once a roof made from asbestos shingles reaches its expected lifespan, which is around 30 to 40 years, some of the fibers may be visible and easily noticed by inspectors and roofers. Many years of wind, rain and ultraviolet radiation may have worn away the granules and outer layer of the material, exposing many of the fibers. This presents a hazard for the homeowner as well as the crew who would be removing the old materials.

If a homeowner suspects that any part of a home could contain asbestos, it is best to leave the area untouched and call in professionals who are experienced in dealing with this material. Even walking on the roof or setting a ladder against its side could release some fibers, causing them to become airborne.
