Heavy Duty Felt Shingle Underlay : 10m x 1m

Heavy duty underlay, perfect for use with shingles and shed felt on a variety of outside buildings. An underlay can help protect your shed for much longer with the added protection and will allow felt roofing shingles to be installed on a lower pitched roof.

It is a fibre based bitumen underlay that will enhance the life span of shingles and shed felt, leaving your buildings looking good for longer.

We recommend this underlay for use with our Supaflex Shingles.
