It is common for a 5-10mm sag to occur in a house roof, internal gutter or barge over time, normally twenty years or more, where the roof no longer remains strictly in line.
Delta Roofing and Manufacturing Ltd custom makes its own flashings for a reroof. This means we fit the roof to your house thus we can guarantee our workmanship and your roof.
Other manufacturers use mass produced barges, ridges & internal gutters, meaning their shape and profile is strictly to paralleled tolerances.
The significance of this is in our leak free guarantee of our work.
Our guarantee is our reputation
