Welcome to Spenglerei Rexhaj – your experienced partner for flat roof construction, waterproofing, and high-quality plumbing work in the canton of Aargau. For many years, we have stood for quality, honesty, and sustainable solutions. Our aim is to implement every project with professional care, on time, and to the complete satisfaction of our customers.

We combine classic craftsmanship with modern materials and techniques – from flat roofs to facades. We focus on durable solutions that are both aesthetically pleasing and functional.

Flat roof construction is our specialty: we offer robust and aesthetic solutions that are individually tailored to your requirements. Whether you want a gravel roof, a green roof garden, or an accessible terrace, we will design your flat roof professionally and sustainably.

In the field of plumbing, we deliver precise craftsmanship for dormers, roof edge finishes, and custom edging. We manufacture all sheet metal parts in our workshop and install them professionally on site.

We also beautify your outdoor area with high-quality garden slabs. Our solutions are not only functional, but also reflect your personal style. Modern, classic, or rustic—you decide.

With our maintenance service, we ensure that your roof remains in good condition for the long term. Regular inspections help to prevent consequential damage and increase the service life of your roof.

Our customers rely not only on our precision craftsmanship, but also on our long-term support. Whether renovation, new construction, or seasonal inspection—your projects are in good hands with us. We provide transparent advice, act in a solution-oriented manner, and focus on long-lasting results. Quality is evident not only in the materials, but in every step of the process.
