Asbestos was incorporated into roofing materials back in the early 1900’s but did seen a rapid decline in use since the 1980’s when the potential hazards of asbestos were recognized. There were many advantages to adding asbestos to roofing materials including: heat and fire resistance, lightweight, excellent strength and durability features. All of these benefits made the use of asbestos widespread in these building materials. Asbestos in roofing can possibly be found in materials such as shingles, underlayment, sealants and flashing. If your roof is being repaired or replaced and you cannot find markings directly on the material or have the product packages to reference it is recommended to hire a WI certified asbestos inspector to sample the materials and have the sent to a lab for analysis. Our highly trained and certified asbestos inspector will send the sample to the lab for testing and results can be revealed a few days after the samples are taken.
Much like roofing materials there were many advantages to using asbestos in cement board siding, adhesives and caulks for exterior construction applications. Again since the 1980’s the use of asbestos in building materials has greatly declined but had not been totally eliminated. Siding manufacturers used asbestos for its resistance to heat, fire, termites and rotting as well as its durability and strength. If there is any question as to the presence of asbestos is any of these types of building materials you may have it is recommended to avoid any type of disturbance to your siding. Even power washing could loosen materials which could release harmful asbestos fibers into the air around your property.

When you are ready to replace or repair your windows be aware that if your windows were installed pre-1980’s there is a high probability asbestos was used in many of the materials. Asbestos was commonly used in the window putty, glaze and caulking to seal windows and glass panels. This putty was used to retain heat, reduce drafts and was fire resistant. Some of this window putty made with asbestos swells, increases in volume, decreases in density and as it ages the putty cracks or crumbles as it wears away causing the asbestos to become friable. If you are replacing older windows or looking to repair or replace the cracked putty and your windows are pre-1980 a proper asbestos test should be done by a licensed asbestos professional. Testing of this asbestos is done by taking a small sample of the suspect material and having a lab test for asbestos prior to any repairs or window replacement. Should the material test positive we would be able to give you a quote for the proper removal and disposal of the asbestos materials.
