When the covering is too old, you need to completely renovate because repairs will not be effective and will prove a wasted expense. Sometimes it is impossible to retain old materials that are incompatible with new products. Furthermore, it may be more profitable in the long term to completely renovate in a case where major damage extends throughout the surface of the commercial roof.

You have to identify the source of the leaks to repair the roof adequately, using compatible materials. In the case of a thermal roof, it is important to change any water-logged insulation to prevent the evaporation of water particles that can cause bubbles to form on the roof.

Sometimes it is only possible to see the damage once the old covering has been removed. An intervention can then be inevitable to ensure the durability and integrity of the commercial roofing.

Roof repairs are effective most of the time. However, we must intervene quickly before the damage goes too far. In fact, it is not possible to repair a badly worn roof that has leaked for a long time. Once an infiltration or other problem arises, it is best to intervene immediately to protect your investment. The choice of the workforce is also key.

Most roofing work can be performed during the winter. However, some products cannot be applied in cold weather, making it impossible to carry out certain work. However, renovation and repairs are more expensive because the snow must be removed and the roof dried.
