         Re-Covering
 
 Residential flat roofs do not always have to be stripped of the existing flat roof layers.. a re-cover of the flat roof is a good option, as removal of the existing flat roof is a more expencive project that is not always financial option.

 The basic Rubber Membrane (torch-on) flat roof re-cover installation is as follows..

--- The bubbles or trapped air and water filled pockets on the flat roof, caused by previous leaking of water into the asphalt
     layers, are cut and sealed.
--- A layer of reconstituted fibre board is nailed onto the entire flat roof area
--- Drip edge metal is installed on the perimetre the top primed with adhesive spray
--- Rubber base sheet is torched on to the fibre sheets
--- Rubber Cap sheet is torched on to the first layers of rubber base
--- the flashngs around chimneys and vents and skylights are flashed with rubber membrane
--- all seams are caulked where required
--- all debris is removed
--- 10 year warranty


   ------the average life span of a Rubber flat roof system is 10 years minimum, dependant on exposure location----
