I need a flat roof relaying.
I have received two quotes.
Quote 1: Strip existing felt
re-cover 1st layer with 4mm underlay torch on felt.
cover 2nd layer with 4mm polyester torch on felt.
Quote 2: Remove existing felt.
Fix to prepared surface a three layer roof pour and roll system. Base layer 180 SBS partially bonded to roof deck. Intermediate layer 180 SBS sanded fully bonded in hot bitumin. Cap sheet 350 SBS mineral fully bonded in hot bitumin & clean lap finished.
The quotes are roughly the same for price.
Does anyone know which is the best system to use or the pros and cons of each.
Thank you
