Theisen Roofing & Siding Co. is a local home improvement contractor based in Northern Illinois, USA, with core services focused on residential roofing, siding, and seamless gutters. According to its website, the company was founded in 1971 and is one of the longer-established licensed, family-run roofing companies in DeKalb County. It lists license number 104-000554 and states that it holds a BBB A+ rating.
The website mainly serves as a company profile and lead-generation channel: it introduces the company’s history, family ownership, service areas, credentials, and project gallery. The gallery includes roofing projects using materials such as GAF Timberline HDZ and CertainTeed Landmark, suggesting that the company primarily serves residential roof replacement and renovation needs. The site also mentions siding and seamless gutters, covering basic exterior and drainage-related home improvement services.
The website does not provide a price list or online estimate tool. Roofing projects of this kind are typically quoted based on factors such as roof size, pitch, material brand, tear-off complexity, and any additional gutter or siding work. Users need to call the office to confirm service coverage and availability.
The main advantages are that the company has been operating for more than 50 years, has three generations of family involvement, and has built strong local trust. It also highlights memberships or ratings from organizations such as BBB, DeKalb Chamber of Commerce, and US Chamber of Commerce. The downside is that the website feels relatively traditional, with limited details on service packages, warranty terms, customer reviews, online forms, or instant booking, making it less convenient for users who prefer comparing options online.
It is best suited for homeowners in DeKalb, Cortland, Sycamore, Genoa, and nearby Northern Illinois communities, especially those looking for a long-established, licensed roofing contractor with a strong local reputation. It is not a good fit for users who need nationwide service, instant online ordering, or transparent fixed pricing.
This is a standard website for a local U.S. business, with mostly static informational content, and it should generally be directly accessible from China. However, its services are entirely local, so its practical value for Chinese users is mainly as a reference for studying how local home improvement contractors operate in the U.S.
