Roof drainage for private, commercial and properties
At Kramer Installation A/S, we carry out roof drainage for new construction, renovation, and existing properties. We assist private individuals, housing associations, commercial enterprises, and industry with solutions that safely direct rainwater away from the roof and protect the building from moisture and water damage. The work is performed with a focus on capacity, operational reliability, and long service life.

Effective drainage of rainwater
A well-functioning roof drainage system must be dimensioned according to the size, design, and load of the roof. We provide advice on placement, capacity, materials, and piping, ensuring that the solution fits the building's other drainage systems. This applies to both traditional solutions and larger systems for flat roofs and commercial buildings.
- Roof drains, downspouts and internal drain pipes
- Gutters and connection to the building's drainage system
- Roof drainage for flat and pitched roofs
- Emergency drainage and protection during heavy rainfall
- Replacement of leaking or undersized installations
- Troubleshooting for backup, overflow and moisture problems

Correct capacity prevents damage
Large amounts of rainfall place high demands on the capacity and function of the installation. Incorrect slope, blockages, or leaking joints can lead to water on the roof, overflow, and damage to the structure. We review the system as a whole and create a solution that operates efficiently and is easy to inspect and maintain.
Renovation and maintenance of roof drainage
Visible leaks, moisture traces, water accumulations, or frequent overflows can be signs that the roof drainage should be inspected. We assess the condition of the installation and advise on repair, capacity improvement, or replacement. During planned service, problems can be detected early before they develop into extensive consequential damage.
