Question 4

How much does it cost to insulate my pitched roof myself?

Accepted Answer

In this calculation example, we look at the situation of the Janssen family. The Janssen family lives in a terraced house built in 1970, with a total floor area of 90m² and a Property value assessment of €380,000. The Janssen family would like to install (pitched) roof insulation themselves. They have decided to insulate the 55m² pitched roof with glass wool or rock wool.
Calculation example (pitched) roof insulation

€ 1.550
Tools (e.g. screws, sealant and paint) and finishing materials (e.g. beams, gypsum fibre boards and/or plaster):
