Roof Renovation Naantali - Here's how it works
Step 1
The roof is inspected and damages are repaired
We begin the work with a thorough roof inspection, where we look for damage, cracks, and weakened areas. We use thermal cameras and moisture meters to pinpoint 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 coat is applied
The first layer of Lava 20 is applied, which begins to form the protective barrier.
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 coat
The second layer completes the protection, making the surface completely waterproof.
Step 7
Finishing touches according to customer preferences
You can add your desired colors or even a walkway to the roof. For example, your company's logo can be outlined on the roof, visible from an airplane or satellite images.
Step 8
The work is inspected
Before handing over the work, we carefully inspect the entire job. We ensure that the roof is even, watertight, and that all details have been executed to a high standard.
