It is important to know: out of an entire home, it is the roof that generates the greatest heat loss!

The good news, however, is that this information contains its own solution: by correctly insulating this part of the building, you can save up to 30% on your energy bill!

This is definitely food for thought...

But… there is a “but”: because even if the operation tends to save money, it begins, initially, by requiring a non-negligible cost, which is not necessarily within the reach of all scholarships.

Don't panic, though: an effective solution exists! It involves installing a temporary under-roof.

Concretely :

The principle of the temporary under-roof is that a flexible sheet is fixed on the underside using a slat which is joined with mastic.
Obviously, the sheet used is completely permeable to water vapor so that humidity can flow normally towards the gutter without damaging the interior beams.
In addition, we can create a channel to secure everything so that the water returns to the center of the leaf.
On the other hand, be careful not to leave any space between the temporary underlay and the roof insulation!

As you might guess, this operation will greatly strengthen the insulation of your roof against the harsh climate. But we must not lie to ourselves, this solution can only be temporary; because water will always seep in at some point.

When you renew your exterior roofing, it will therefore be more than wise to have a real roof covering installed. In the long term you will definitely be a winner!
