Why a flat roof?

A properly installed flat roof can last for more than 20 years and maintenance cost for these types of roof is generally low.
What materials are used for a flat roof?
There are different types of flat roofs available to be installed but we only install 2-ply torch-down bitumen. A fire protection board is installed on top of the insulation before installing two layers of torch-down sheets.
A base layer is torched down with heat before torching down a cap layer with granules on the top.
Can shingles be installed on a flat roof?
As per the manufacturer’s guidelines, roofing shingles can only be installed on roofs with a pitch value of more than 3/12. Some roofers make the mistake of installing shingles on a flat roof and it is almost guaranteed to leak.
Every year we take on many such small projects where we remove the shingles and replace the roof with a properly installed flat roof that would last for a year without any issues.
