Plumbers, electricians, painters, flooring, kitchen remodelers, roofers, landscapers, etc. 

My roofer replaces the roof and charges $25,000.  

We know a good roofer in Madison.

Get more bids and opinions from both licensed and unlicensed contractors.With the roof, I have a roofer that is reasonable and a good guy who will repair rather than replace and be reasonable with you.

Your roofer needs to "uncover" some of his work, so the inspector can see it.

For example, my roofer is in his 50's, owns a business with about 30 employees, and has a dozen or more rental houses.

B) Generating a list of Reliable ContractorsCarpenters, Electricians, Plumber, Roofers, Window guy etc..Reaching out to contractors and evaluating them on factors such as:1) Professionalism - They are insured and present themselves as a business not just a on the side guy.2) Referrals - Follow up on referrals to insure work is completed with quality, insuring customer was satisfied with the overall experience of working with them and preferably finding contractors who work with investors and know the timeliness investors demand3) Pricing - How do they price a job, should I focus on per sq. ft. or is their knowledge that investors are looking for low costs simply enough and competing quotes will determine lowest costsWHAT ELSE?

I've had three times now when roofers (probably the most dangerous of all jobs involved in a rehab) have handed me perfectly good looking proof of insurance forms and they didn't have insurance!
