Flat roof repair

Flat roof repair – basic recommendations from a specialist. The work begins with determining the size of the damaged area, removing the peeled fragment, and then drying the base. If water has entered the basalt insulation, the price of which is determined by its parameters, the damp thermal insulation must be dried. Otherwise, the efficiency of the roofing thermal insulation may be significantly reduced.

Minor damage to the bitumen roof is repaired by applying one or more patches treated with elastic roofing mastic or another moisture-resistant compound with similar properties.

Each subsequent patch should be larger than the previous one, the top one should overlap the repaired area by 10-12 cm.

The mineral sprinkling of the lower patches after treatment with oil is easily removed with a scraper. Correctly selected color and texture of the top sprinkling will make the repaired fragment almost invisible.

To restore the sprinkling layer, you can use coarse sand, crushed glass, or another weather-resistant material that is suitable in appearance.

To remove the swelling on the roof, a cross-shaped cut is made. The petals are bent back to remove water and dry the base. When ready, the petals are treated with mastic and pressed tightly to the work surface. Installing a patch according to the standard scheme.

Flat roof repair – repair of membrane roofing

Membrane roofing has proven itself well in flat roof structures, the price of the material meets all the characteristics of modern requirements.

For temporary repair of membrane waterproofing, the damaged area must be cleaned of mineral and organic contaminants and degreased. Then a patch is cut out of self-adhesive tape, which is applied to the damage and rolled with a roller from the center to the edges.

The durability of such repairs is several years. But for a complete and long-term restoration of the tightness of the membrane roof, it is better to use heat welding with a hand-held construction hair dryer.
