At Gunite we provide and install fully guaranteed flat roof membranes for the new build and refurbishment markets. Working closely with several of the leading system manufacturers, we carefully select the best system for each project.
No hot works: all of the systems we install are cold applied, thus eliminating the risk of fire and injury through burns to operatives, building occupants and the general public.
All of the systems are available guaranteed for either 10, 15, 20 or 25 years.
Green Roofs
Green roofs provide a cheap way of alleviating flooding, combating global warming and improving air quality. We can provide locally tailored conservation solutions as well as improving the asthetics of the building. The landscape variations are practically limitless.
Liquid applied membranes
Liquid applied systems offer a high degree of flexibility; it is often possible to overlay an existing surface thus avoiding the need to strip existing coverings and expose the roof to potentially damaging water ingress.
Liquid applied membranes are useful in the following situations :-
-
Non-slip balcony or walkway decking
- Simple overlay of felt, asphalt or directly onto timber or concrete substrates
- Fully built up tapered or flat board insulation systems
- Green or sedum roofs
- Gutters
Single ply membranes
A mechanically fixed single ply sheet roof is generally rapid and economic to install and, due to its lightness in weight, will often enable savings to be made on the supporting structure. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy. Similarly, any damage is easy to spot and repair.

In a warm deck roof construction, the insulation is placed above the deck, thus ensuring that the deck remains at around the same ambient temperature as that within the building. Warm roofs can be constructed as exposed membrane roofs or ballasted with large rounded stone, decorative gravel or pavers. |

In a cold deck roof construction, where this is permitted by the Building Regulations, the insulation is placed between the rafters and below the deck, which is usually timber based, thus ensuring that the deck remains at around the same ambient temperature as that being experienced outside the building. |
