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.

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!

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?

Eagle view is an app that insurance companies and roofer's use to get the square footage of a roof. 20 bucks will give you a basic measurement. 50 bucks gives you a detailed measurement.

For example, roofers in one area can charge vastly different rates than roofers in another, mostly due to local ordinances regarding permitting, licensing, insurance, minimum wage laws, etc.  

Wondered if anyone had a recommendation for a good and affordable roofer.

My GC had a roofer but has been unresponsive so looking for options.Thanks

Matthew,Have you already secured the roofer for the work?

I also have a bit of a construction background having been a roofer and operating my own roofing business for several years.

Have a team - handyman, plumber, roofer that can communicate with you via phone and/or email.
