Hi, I need to replace the felt roof on my garage and got three quotes, but I'm not sure if the materials or methods used are different or which sounds like the best option. The quotes were:
a) 1st layer bs747 type 3b, 2nd ht180 bonded in hot bitumen, 3rd technatorch sbs torch on green mineral cap sheet
b) 1b vapour felt, 2 layers hot bonded 3b mineral felt.
c) refelt 3 layer built up high performance system finished in torch on mineral
if any makes any difference they are in price order, most expensive first.
Thanks
