Washtenaw County, Michigan Rat Control Services
Rodent entry elimination: We see many attempts by handymen, pest control companies, and Washtenaw County, Michigan rodent extraction companies that do not include the removal of any roofing material. Often the prevention includes the emptying of a can of foam into the void. Without the removal of roofing material, there is no assurance that rodent entry will be eliminated. When we encounter these substandard attempts, we must first remove the previous application. When this includes foam, the extraction of the foam takes longer than the application of our wire prevention product.
Rodent elimination by those who are not insured exposes you, the Washtenaw County, Michigan homeowner, to unnecessary liabilities. It is in your best interest to request proof of insurance for worker’s compensation and public liability before work begins on your roof. It’s doubtful that you will find these companies or individuals carry such insurance. Those who do not often work in this environment typically cannot afford expensive roofing insurance.
