Flat Roofing Systems
C. Stevens Roofing offers three types of flat roofing depending upon the location
and environmental conditions. See details below.
The most common system used by C. Stevens Roofing is polyester combining value, flexibility
and a 12 year guarantee. NORDGUM is one of the most convenient solution for roofing
and renovation works and waterproofing details. Good values of mechanical resistance
thanks to the non woven polyester carrier and excellent low temperature flexibility
permit to use it in difficult climate conditions at economic rates.
The greatest test of any construction material is how it performs under field conditions.
The first membranes laid in the 1960's are still protecting flat roofs some 40 years
later with over One billion square metres installed worldwide on Commercial and Industrial
buildings including Offices, Schools, Hotels.
Durability assessments of roofing membranes found EPDM as the only membrane with
no reduction in flexural fatigue resistance for all tests/locations, It would take
over 50 years for EPDM to drop below 200 elongation, the MRCA ME-20 performance requirements
for aged sheeting.
GRP is a specifically modified high performance waterproofing system, designed to
a provide a permanent solution to the problems usually associated with bitumen based
coatings. For example cracking and blistering of the surface caused by the effects
of sunlight which can result in failure of the roof within a few years
GRP more commonly referred to as "glass fibre" is formed in situ by reinforcing
polyester resin, which has been cured or hardened using a peroxide based catalyst
with an emulsion bound chop strand mat. Once cured this forms a joint free laminate
that will outlast virtually any other traditional roofing material.
