Or the repair

In this case, it makes sense to partial repair of the roof, or the repair of the roof with the imposition of a new material on the old.

It is worth noting that the repair of the roof by applying a new roofing material on top of the old can only in some cases — when a flat roof is used, when soft roofing material is used, when the fastening of roofing material is not achieved due to the use of screws and such a hardware.
