Before You Call Shamrock Roofing Co.

1. Do you take moisture readings every day and will you give me the drying log?
2. Are your technicians certified in water damage restoration?
3. Where is your company based, and how long have you worked here?
4. Will you photograph the damage before you tarp or board?

Missouri has no statewide general contractor license, so check with your city or county, and in Illinois ask a roofer for a state roofing license. Also ask for proof of insurance and industry certification for the restoration crew.
