A house quickly loses 20 to 30 percent of its heat through the roof - especially if the insulation is outdated or non-existent. For owners, roof insulation is therefore one of the most effective measures for increasing energy efficiency. It reduces heating costs, improves the indoor climate and increases the value of the property - often with state subsidies.
Differences in insulation
Depending on the construction of the house and the use of the attic, different methods are possible: above-rafter insulation, between-rafter insulation or below-rafter insulation. If you don't use the loft as living space, you can also simply insulate the top storey ceiling. This option is particularly cost-effective - and in many cases even mandatory according to the Building Energy Act.
Promotion and value enhancement
Investment in new roof insulation is subsidized by the state - for example via the BAFA or KfW programs. It can also be tax-deductible if certain conditions are met. Owners benefit in the long term through lower energy costs, better heat protection in summer and an increase in property value - especially when selling or renting.
Planning by specialist companies makes sense
Insulation should always be planned and implemented professionally - if only because of the potential risk of moisture and mold if it is not implemented correctly. An energy consultant will help you choose the right method and the right funding.
Conclusion
Insulation pays off - especially on the roof. Owners who act now will save energy in the long term, increase comfort and secure the value of their property for the future.
