Flat Roof Repair without demolition or unnecessary interruptions
A roof can last for years, but damage can develop quickly: cracks, leaks around penetrations, depressions, or wear. Timely repairs prevent more extensive damage and save on costs. We repair felt roofs without unnecessary demolition, operational downtime, or disruption to your daily routine.
When is roof repair appropriate?
The roof leaks in isolated spots
Water seeps from penetrations or seams
The roofing has cracks, indentations, or detachment
Repairs have already been attempted, but the problems persist
You want to ensure that you have the best possible roof.
Repairs can restore the roof's functionality for years to come – provided they are done carefully and with the right methods.
Complete installation. Complete protection.
Step 1
The roof is inspected and damage is repaired
We begin the work with a thorough roof inspection, looking for damage, cracks, and weakened areas. We use thermal cameras and moisture meters to locate where water is leaking in. All defects are repaired before installation.
Step 2
The surface is washed and primed
We thoroughly clean the roof, removing loose dirt, moss, and other impurities. Priming the surface ensures that the coating adheres properly and remains in place for a long time.
Step 3
Penetrations are sealed and finished
All roof penetrations, such as chimneys and ventilation pipes, are carefully sealed.
Step 4
The first layer is applied
The first layer of Lava 20 is applied, beginning the formation of the protective coating.
Step 5
Fiberglass reinforcement is installed
We use fiberglass reinforcement to strengthen the structure and improve the roof's durability.
Step 6
Applying the second layer
The second layer completes the protection and makes the surface completely waterproof.
Step 7
Finishing touches according to customer wishes
You can add your desired colors or even a walking path to the roof. For example, your company's logo can be outlined on the roof, visible from an airplane or satellite images.
Step 8
Workmanship inspected
Before project handover, we carefully inspect the entire workmanship. We ensure that the roof is even, watertight, and that all details have been executed to a high standard.
