When selecting a contractor to clean your roof, it is important to protect yourself from fraud and liability. Here are some guidelines to help you choose a qualified, experienced roofer:
Check for a permanent physical location, tax I.D. number, and business license.
Repeatedly changing their contractor number or multiple business closures and reopenings could be cause for concern. You can check this by calling the State of Washington Corporate Division.
Check to see if the company is properly licensed or bonded.
Ask to see proof of contractor's liability insurance coverage, making sure the coverage is up to date.
Look for a company with a proven track record that offers client references. Talk to the customers to find out whether they were satisfied.
Are they a member of the Better Business Bureau? Generally, if they don't want to be accountable or tracked, they won't join. Contact the Better Business Bureau to check for a business report on the company.
Don't give them any money until the job is totally completed. Some contractors have been reported for taking a percent of the money down for a partial job, and then never returning to finish. There is an exception when purchasing a new roof. Sometimes a percent is required when purchasing material.
Price is only one criterion when selecting a contractor. If it sounds too good to be true, it just may be. Professionalism, quality, and integrity should be the utmost when making this important decision.
