About Muller Exteriors—One of the Leading Window Companies in Chicago


Since 1980, Muller Exteriors has been a family owned and operated roofing company that strives to provide quality work at a reasonable price. To take that one step further, our certified roofing contractor offers a 10 year labor warranty on all replacement roofing and siding projects. With over 39 years of experience, you can rest assured that you are in capable hands.

Do you need a new roof for your newly-bought home but you’re having a hard time picking the perfect material? Do you feel draft from your windows? Or perhaps your siding is starting to fall apart and you think a replacement is in order. Your best course of action in any of these situations is to contact one of the leading roof, siding, and window companies in Chicago—Muller Exteriors.

When it comes to projects like these, never risk DIY. That’s the most unwise decision you could make, especially if you don’t have any background whatsoever in home repair or renovation. Leave that to the experts from our local roofing company to ensure good quality work that will last a lifetime. Rather than saving a little now and spending more on repair and maintenance tomorrow, why not invest a little more in professional services upfront and avoid future repair and maintenance altogether?
