I'm a project manager for a roofing company in Giessen, and due to a problem that arose requiring a roofer, I spoke directly with the owner, Mr. Petrowski, and I'm absolutely thrilled. He helped incredibly quickly and was highly competent. It's rare to find such fair and reliable companies these days – simply wow! The work was carried out cleanly and professionally, and the employees on site were friendly and very knowledgeable. I can wholeheartedly recommend Christian Petrowski Roofing GmbH in every respect. Top company, top-notch workmanship – a clear recommendation!
