While Chicagoland has its fair share of flat and low-slope roofing, there’s plenty of shingle roofing to be found across the area. In fact, asphalt shingle roofing systems account for the majority of single-family homes in Chicago. Homeowners with asphalt shingles know they can become dislodged during high winds and storms, from damage caused by falling objects, or by walking on them regularly. What many don’t know is that even a single missing shingle can be a bad sign.
