Sometimes there is a need to repair the roof of the house, garage or other outbuilding, investing at least efforts and means. The ideal option is the overhaul of the roof, but we cannot allow it annually due to the fact that our roof began to flow in one or two places, damaged by bad weather. 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. In most cases, they are engaged in such a blood repairs on bitumen roofs, so we will talk about them.
The bitumen roof is easily repaired, and the new layer of bitumen can be put on top of the old. However, you should not think that you will be able to avoid preparing the old layer. All bubbles, bulges, detachment must be thoroughly cleaned and dried, since in the future they can create the same problem that was created before the roof repair. Do not be afraid to cut the bubbles, drying them completely, because from above they will be closed by new material. Excess of old material can be cut off so that the surface of the roof is even. On the flat surface of the roll of bitumen material will be laid much more quickly and efficiently. Laying bitumen material is done using technology.
It is worth noting that the preparation of the old layer is important in time to repair the roof by applying new material, and the better it will be, the better. The main danger in this case is an incomplete drying of the layer, which will be after repair from below, since the presence of moisture will cause the appearance of bubbles and bulges, which will lead to the same problems for which the roof repair begins.
