In our Canadian climate roofs are exposed to a wide variety of weather conditions. Strong winds, freezing and hot temperatures, heavy rain and snow all take their toll. Furthermore, animals looking for den sites will break off shingles resulting in exposing roof boards to the elements.
Conducting a minimum of two inspections per year will reveal areas where the roof repair is needed, thereby avoiding water damage and potential mold. Wildlife has the innate ability to locate and exploit areas where damage went undetected and water has caused the rotting of roof and fascia boards.
In this context, eavestroughs need to be cleaned before winter sets in to assure unimpeded water flow away from the building. Twenty percent of all wildlife entry holes are created where water from clogged eavestroughs has caused the fascia board and overhang to deteriorate.
