When a Plan comes Together

We believe that failing to plan is planning to fail, which is the very thing we don’t want your roof to do so we will advise you on all aspects of structural decking material and design. Before we can install any system the underlying deck must be safe, long-lasting and meet all the appropriate building regulations.




We’ll also take care of all the detailing considerations such as ensuring rain water will run-off properly and that the gutters will be in the right place to catch it. Sorry car, garages don’t need to be insulated but where a roof is part of a heated, habitable part of the house like a kitchen or a bedroom, it will need fully insulating with fire-safe insulation boards. You’ll be warmer and your heating bills will be smaller.



Top That

The traditional way to waterproof a flat roof is by building up 2 to 3 layers of bituminous felt, bonded together one on top of another. The quality and performance of felt membranes has improved over the years and are known today as Reinforced Bitumen Membranes or RBM and remain a firm favourite for residential applications. All felt systems will need an application of a solar protective finish and additional fire protection.

Gaining in the popularity stakes however are PVC single ply membranes, not least because of a certain significant advantage that these systems need only one layer, so installation times can really move up a gear. A reasonable estimation would be getting on for up to 3 times quicker than good old felty.



Single ply PVC

Single ply PVC is best suited to warm roof installations being laid directly onto the insulation material and mechanically fixed with a system of steel fasteners which is fast and efficient. Extremely durable and lightweight, they put little stress on your structure and your lovely roofers and are resistant to fire.

Sloped Roof

But it’s not just flat roofs that PVC can transform. Because it is so pliable and adaptable we can use it on sloped roofs as well as creating more complex designs such as convex, concave and even vertically pitched. We can also provide an enticing colourful choice too including the authentic look of lead, copper and zinc together with standing seams to complete a truly realistic effect. Your neighbours will never know the difference.



Wind Resistance

It may be stating the obvious, but all roof systems and their insulation must be constructed to resist the invisible evil forces of wind and gales. The last thing you want to see in the morning is the top of your beautiful new extension flapping about like an uncontrollable deckchair. When you entrust your new roof installation to the care of Flat Roof Repair Dublin our specialist roofing professionals will keep everything stuck down all good and proper.
