Self-adhesive roofing system.

System and materials required.

Page 3

The Coldseal system has been developed to make flat roofing more straight-forward and economical for the jobbing builder, small roofer or experienced DIYer, to a professional quality standard
There is no need to use hot bitumen, gas torches or large amounts of messy liquids, and only basic skills and tools are required. Tough and durable, the Coldseal system is designed to be clean to handle and, in conjunction with the revolutionary Quick Trim Roof Edge System, is simple to install.
Coldseal is a two layer high performance, self-adhesive system that is ideal for replacing an existing roof covering or installing a new waterproof surface on a properly prepared deck on many types of roofs including garages, dormer windows, porches, and extensions to habitable buildings.
N.B. This system is not suitable for overlaying existing roof membranes.

MATERIALS REQUIRED                          Page 3 Helpful formula for calculating the quantity of materials needed.
Material Quantities. The amount of materials required for any flat roof will depend on how simple or complex the  roof is; the number of changes of surface level, water run offs, curves, flashings and gutters there are determine the amount of material required. The following gives a rough guide to calculate the basic requirements. The Coldseal system is made up of four elements and materials can be calculated as follows.

Coldseal Underlay and Coldseal Top Sheet.

  Below a useful formula for calculating materials   quantities
Underlay is supplied in 8 metre long x 1 metre wide rolls and Top Sheet in 6 metre long x 1 metre wide rolls.

Calculate the flat area of your roof in square metres (see fig. 4, length x width). Add 10%  for laps and wastage. Add to this the total linear metreage of the upstand detail (the abutment with the main house, if applicable) of your roof multiplied by 0.3m.

Where there are larger upstand details such as parapets walls the multiplier of 0.3m will not be adequate; additional material will have to be allowed for. Divide total square metres by eight for Underlay and six for top Sheet to give you the number of rolls needed.

Flat Roof Area (length x width) = m2
10% for laps etc. (area m2 x 0.1m m2
Roof upstand x 0.3m* m2
TOTAL m2
Divide by 8 for Underlay = Roll Required
Divide x 6 for Top Sheet = Rolls Required
* When using traditional detailing add sufficient material to cover the open perimeter details (open roof edge x 0.3m)
Coldseal SA Primer. Supplied in 5 litre tins. One litre should be sufficient for 4-6 m2 of roof area Coldseal Lap Mastic. Supplied in 310ml cartridges: The cartridge will fit a standard (skeleton) gun and covers approx. 3 linear metres
NB. The above coverage's are given as a general guide only. Quantities of primer, membrane and mastic may need to increase if roof edges are long and shapes and details are intricate or complex.
