Felt
Built up felt roofing consists of two to three layers of bitumen sheet that have been bonded together using either hot bitumen or adhesive. With an average life expectancy of 15 to 30 years, flat felt roofing is economical but has a tendency to crack as it ages and the temperature changes.
PVC single-ply membrane
PVC single-ply membrane is vinyl chloride monomer (VCM); the gas is polymerised to produce a vinyl resin that is then compounded to produce a material known for its flexibility, durability and colour options. Suitable for all flat roof constructions and situations, they are ideal for domestic, commercial and industrial flat roofs and are known for their value for money.
I've been recommended the PVC roof...it's £400 more expensive then the felt but comes with a 20 year guarantee...
Anyone got any past experience ? Is it worth the extra ?
