D & J Roofing and Solar have great "Flat Felt Roofing Solutions" 

D & J roofing are approved installers of Europolymer torch applied built up felt systems for Flat Felt Roofs. 
 
At D & J Roofing and Solar we prefer to use either the two layer diamond SBS system or the four layer diamond SBS insulated system. 
 
The diamond SBS range is a flexible waterproofing system and is an innovative torch applied SBS membrane produced to CE standards. 
 
The four layer system consists of one layer of TD underlay heat transfer felt, loose laid on to the deck which creates a vapour barrier.  
Torch the mineral membrane surface which adheres the TD under to the deck, by heat transfer. 
 
As part of the same process the insulation board is pressed onto the membranes non viscous surface, fixing it in place.  
The next layer of TD underlay is loose laid over the insulation.  
The TD underlay is then bonded to the insulation by heat transfer as part of the process of torching the mineral coated capsheet over the TD underlay. 
 
This process reduces the risk of fire to the roof deck and damage to the insulation as no flames are directly applied to them. 
 
With this system we can offer gurantees of 10-20 years depending on what and where it is used. 
 
Evo 10 is a mineral overlay systemthat requires no priming or blackening out of existing mineral finnishes. It can be used as an overlay to both mineral felt and asphalt roofs. It benefits from dual bitumen technology and offers a gurantee of up to 10 years. 
 
Evo 15 
Evo 15 is a mineral overlay system that requires no priming or blackening out of existing mineral finishes.  
It can be used over existing asphalt also, and benefits from dual bitumen technology offering a guarantee of up to 15 years. 
 
Evo 20 
Evo 20 is a mineral overlay system that requires no priming or blackening out of existing mineral finishes. It can be used over existing asphalt also, and benefits from dual bitumen technology.  
With minimal preparation, this single layer application reduces environmental costs of the disposal of the existing roof system and offers guarantees of up to 20 years.
