Roof ridges sit atop the ridge of a roof and help stop the growth of algae, lichen and moss building up. This is a low-cost way to eliminate the dangerous task of cleaning the roof in the future.

Copper is the perfect material for roof ridges as it reacts with the air and rain causing the copper to oxidise. Once oxidised, the copper ridge produces copper sulphate; this fungicide is a highly effective moss killer whose effects last for years. Moss is one of the most detrimental substances to appear on roofs, as even the smallest build-up will act like a sponge and absorb any water which it comes into contact with. This creates enormous stress and adds additional weight to the roof which will, in time, weaken the structural integrity of the roof and shorten its lifespan.

Frost is another hazard to roofing, which can at times push and shift the tiles from below. However, with a copper ridge, this danger is eradicated.

Metal Gutta sells copper ridges in 2.4m lengths, which can be cut to suit on site and is one of the most inexpensive and environmentally-friendly approaches to protecting and increasing the longevity of a roof. 60% of the copper used in Metal Gutta’s production is recycled, giving it the moniker of a “green material” not just for the fact it turns green over time.
