This came as a fax for Advance Roofing.
The 856 number is from from NJ
An alternative phone number on the same add is 215-881-5969  which is from Philly

If a business doesn't ID themselves properly and uses Private Number to send Faxes then I want nothing to do with them.

While they have a removal number of 1-800-410-5894 I doubt it works.
