In particular, it is possible to detect problems to locate them and to know their extent. What are the items to inspect? First, the frame does not need to be maintained. Except in case of defects, its installation and its hold are perfectly durable. Be aware that the under-roof screen does not require maintenance either.This is not the case, for example, attics. Indeed, this part is sensitive to the infiltration of water in the roof and the accumulation of moisture under the roof and in the insulation. Better to monitor the condition of your attic several times a year. In the same way, the control of the insulation must be regular. This is to ensure that it is dry and that no animal has come to embed itself.
