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.

Built-Up Roofing

Multiple layers of reinforced scrim or felt between moppings of asphalt or coal tar pitch has been a staple in Chicago roofing for well over 100 years. Top coatings of gravel embedded in asphalt or coal tar, asphalt top coat and aluminum coating offer different reflectivity for different situations.

Modified Bitumen Membranes

This material consists of fiberglass, polyester or a combination of both polyester and fiberglass scrim sheets laid between or set on top of molten modified asphalt and then cooled to form a pliable roof system in rolled form. The (2) types of modified bitumen products offered are APP (actactic polypropelene) and SBS (styrene butyl styrene). These are tough roofing products that are excellent in dealing with the weather extremes in the Chicago area and can handle foot traffic better than most other roof systems. Combine either product with built-up roofing plies and we can offer warranties up to 25 years. Many surfacings are available for these products such as asphalt emulsion, aluminum coat, granulated surfacing in different colors, asphalt and gravel and acrylic coatings. This roof system is one of the most popular roofs being installed in Chicago.

White Membrane Systems

PVC/TPO roof membranes are eco-friendly easy to install roof materials that are reinforced which makes them pliable and puncture resistant. Electronic heat welding of the seams makes this an environmentally friendly process to form a very strong seal. Manufacturers make these products in different thicknesses and colors. These products are Energy Star compliant and meet all Chicago area and federal energy codes.
