Flat Roof Products

With flat roofs becoming more and more popular with Architects and Designers it is important to use the best products to finish your project.

Flat roofs are notorious for giving issues if poorly constructed or if the incorrect products are used. All concrete will retain an element of moisture within its mass after the construction process, and it is important that once the roof is waterproofed, there is still a way for water vapour to escape from the concrete slab. If not, there is a risk that this retained moisture can build up pressure points beneath the waterproofing membrane causing the waterproof membrane seal to bubble, blister or even burst. Therefore, vents are an essential part of a waterproofed concrete deck. Vents should be placed at least every 25m2. The vents are available in TPE and EPDM with perforated flanges. A PVC version with a smooth flange is also available. The PVC version has a smooth flange as it will be welded or adhered to the waterproofing membrane forming a seamless band.

At NorthWest Aluminium we offer a full range of products to ensure the best possible finish to your flat roof.

  • Flat Roof Rainwater Outlets - The junction between drain pipes and the holes cast into the slab are the areas most susceptible to water ingress, since the maximum amount of water run-off is coming into contact with them. It is essential that the deck structure is completely sealed around and into these details, to prevent leakage.
  • Leaf guards and gravel excluders are required for circular roof outlets to prevent the HDPE drain pipe becoming blocked over time, leading to flooding. The leaf guard is inserted into the top of the hole. The serrated edges will grip onto the inside of the drain connector or outlet.
