Maintenance Programs and Roof Repairs


Regularly scheduled roof inspections and maintenance is very important to maximize the life of an existing roof system. Many roofing manufacturers recommend or require annual or bi-annual inspections of their roof systems to maintain validity of their warranties. We at Allendorfer Roofing Company, Ltd. feel it just makes good sense to have a professional watch over and maintain your roof on a regular basis.

Weather extremes in and around the Chicago area are brutal on roofing systems. Heavy rains, wind and hail can damage commercial roof systems, industrial roof systems and residential roof systems in spring, summer or fall. Winter winds, heavy snow fall, temperature extremes causing expansion and contraction and freeze/thaw cycles can wreak havoc with most roof systems.

Most commercial, industrial and condominium buildings have roof-top mechanical equipment which get serviced or replaced regularly. Satellite dishes are being installed on many residential, condominium and apartment roofs. Between roof traffic and contractors who don’t properly protect the roof can result in extreme wear or damage to the roof.

Chicago Roof Maintenance & Repair Done The Right Way!


With scheduled roof inspections in the spring and/or fall we can locate and repair small problems before they become large, damaging leaks. During our inspections, our trained staff will look for and remedy open pipe flashings, open field seams and caulk joints, plugged drains and rooftop debris. We can help you get the most out of your roofing investment.

An often overlooked aspect of roof maintenance is the reflectivity of some flat roof systems. Not only do reflective coatings protect your roof, they save on energy costs to cool your building as well as reducing heat island effects in populated areas. Unprotected asphalt roofs, including modified bitumen roofs can degrade from the sun’s rays. Asphalt-based aluminum and acrylic coatings can help protect, and add years to the life of your roof. There are coatings available for most single ply and metal roof systems.

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.

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.
