What Our Customers Say
Lanz Garcia2022-04-04 Excelente trabajo Joe Olivier2020-12-03 My front porch roof and gutters were destroyed by a fallen tree during a storm. I received three bids for the job and Allendorfer came in the middle, but they were the most thorough in terms of their written estimate. Work went smoothly once they received the deposit and the work was done very well. Communication with the office was great. I plan on working with Allendorfer in the future for any roofing and gutter work and will recommend to friends and family. DM WS2019-09-17 Outstanding job. Did a 90' x 30' flat condo roof in the 60656 area. Starting work on a 40+ year disaster and left it a "shining gem". Commercial gutters, downspouts, rebuilt the chimney and installed a cap. Building is unrecognizable. The top floor can't say enough good things about the insulation and noise reduction. If you are looking for decent, honest people who know their stuff than please give them a chance. Fair pricing, top quality materials (not second hand knock offs) and punctual top notch performance. Thank you Rich and crew for an outstanding job, peace of mind, patience and a sense of humor. Roger Clemson2019-04-17 Excellent roofers who were punctual, hardworking and did a great job fixing our roof. We recommend Allendorfer Roofing as a professional and honest company that does the job. Thank you Conrad and Richard and your roofing crew.
