Roofing failures are often blamed for many water intrusion and mold claims. Contractors often blame the roof and most homeowners simply don't know. Frequently, MECF finds poor ventilation and/or insulation issues causing the problems. Our knowledge of roofing, HVAC engineering combined with thousands of investigations allows us to quickly and accurately determine the cause or often causes.
A claim we investigated was initiated by a new homeowner, the attic was a mess, heavy mold contamination on a newly installed roof deck, water was dripping from the shingle nail penetrations. The roof shingles were installed by previous owner the year before. Cause, inadequate attic ventilation. The roofing contractor was, in our opinion, responsible to inform the owner of the need, failure to inform is negligible.
Another claim found a converted cottage with an elderly couple using unvented propane and kerosene fueled heaters with extensive water dripping from the ceiling. The roof was nearly flat and recently shingled, MECF found evidence of some minor seepage through the roof due to ice dams, however, the saturation of the roof deck was extensive with frost and water dripping from everywhere. The unvented combustion was converting about 90% of its weight in fuel to water vapor!
MECF has also saved many insurers from needlessly replacing roofs and eliminating the problems with simple changes in ventilation or insulation. We have also found cases where the shingles are defective.
