A roof renovation is one of the most important renovations your house will ever need. The roof protects the entire structure — when the roof is in good shape, the rest of the house stays dry and healthy. Kotikatto.fi is Finland's most comprehensive roofing expert and guides you through every step.
When is a roof renovation needed?
A roof's lifespan depends on the material. A metal roof typically lasts 40–60 years, a tile roof 40–80 years and a felt roof 15–25 years. Regular inspections reveal the right time for renovation. Signs that renovation is needed include roof leaks, worn covering, moss growth and underlay condition.
Roof renovation steps
A roof renovation always starts with a free inspection. We assess your roof's condition by drone survey and give you a fixed quote. The work stages are: old covering removal, substructure inspection and repair, new underlay installation, new roofing material installation, sealing of penetrations and chimney flashings, and a final drone inspection.
Roof renovation price
The price depends on roof size, material and condition. Indicative prices: metal roof 50–70 €/m², tile roof 70–100 €/m², felt roof 35–55 €/m². Request a free quote for an exact price for your roof.

Repair or replace?
Small damage such as a single leak can often be repaired without a full renovation. If the roof leaks in several places or the material is extensively worn, a full condition assessment reveals the situation. Based on the assessment , we recommend either repair or replacement.
