An efficient, high-quality roof renovation in Mortsel, focused on dark roof tiles, a sleek finish and the seamless integration of solar panels for maximum green energy.
In Mortsel we completely renewed the upper shell of this home. The work included a complete roof renovation with new, dark roof tiles and the installation of high-efficiency solar panels on the renewed roof. By tackling the roof and the energy installation in one project, we ensure flawless waterproofing and a sleek, integrated end result.

Frequently asked questions About this project.
Can I put solar panels on my existing roof?
That depends on the condition of your roof. We always come on site to check the supporting structure and the roof covering. If the roof is dated, we advise renovating at the same time to avoid paying twice in the future.
How long does the work take?
A combined roof renovation with solar panel installation is usually completed within 2 to 3 weeks, depending on the weather.
Do you also take care of the insulation?
Yes, we integrate the most efficient insulation materials (such as PIR) when renewing your roof, so you qualify for a better EPC label.
