A roof that is nearly level or slightly pitched is called a low slope or low pitched roof. No roof should be dead level flat; it must have at least a slight slope to drain.

Professionally done low pitched roof waterproofing is a must, for various reasons. For one, leaks and flooding cause mould, which in itself is a health hazard. Repeated leaks may result in structural damage of your house or building, and this results in a loss in property value. If you notice wet spots on your ceiling after a major storm, there’s a good chance that your home already has a leak and needs serious attention.

According to the South African National Building Regulations and Building Standards Act, all roofs should be constructed so as to prevent damage from the elements, including wind and water. For this reason, low pitched roof waterproofing is essential.

What Does Waterproofing Your Low Pitched Roof Entail?

We’re systematic in our approach to waterproofing low pitched roofs. The Multi-Dex system is a reliable way of ensuring full waterproofing.

Step 1:

  • 25 mm thick Multi-board is placed over the low pitched roof. The Multi-board is made of moulded polystyrene and offers insulation and sound proofing.

Step 2:

  • A 3,2 mm support board is laid over the Multi-board panel, offering extra strength and solid support for the next layer, being the waterproofing membrane.

Step 3:

  • The layers are fastened to the existing substrate using 75 mm fasteners and our exclusive washer system, designed for the Multi-Dex System.

Step 4:

  • The overhang of metal roof sheeting is cut back at the gutter end, to facilitate the fitting of metal flashing at the gutter junction. This step is important in sealing the gutter junction to eliminate the back flow of water into the structure’s woodwork behind the gutter.

Step 5:

  • A 4 mm, dual-reinforced Torch-On waterproofing membrane (Derbigum) is gas-welded onto the support board. (75 mm overlaps and 100 mm end-laps).

Step 6:

  • he entire parapet wall is covered using the 4 mm, dual-reinforced Torch-On waterproofing membrane (Derbigum).

Step 7:

  • A specialised modified bituminous aluminium coat is applied, ensuring UV stability and longevity. This specialised coating offers several advantages to conventional aluminium paint.
