Once correctly installed, zinc is an ideal roofing material and is one of the most widely used materials for standing seam metal roofs across the UK. Zinc can be used on a number of different types of roof however, in standing seam metal roofing, zinc normally requires a minimum roof pitch, usually in excess of 3 degrees.
On areas that do not have this pitch, zinc roofers can utilise other zinc sheet techniques such as batten roll. These heritage roof skills look striking and can hep achieve a roof that will last up to 100 years or more.
Zinc for roofing or cladding, in its natural form, may require specialist pre-treatments to ensure that it is suited to its use. It is crucial that the geographical location of the project is taken into account. Nowadays, Zincs with special protective layers that don’t detract from the appearance of the metal are often used to ensure longevity.
Additional protective layers are used for zinc roofing in locations which suffer from harsh environmental conditions, particularity coastal locations, highly polluted areas or atmospheres with a high salt content.
Often zinc cladding (as opposed to the roof area) requires a heavier gauge to ensure flatness and avoid ‘oil canning’ or ripple on the final appearance. Experienced zinc roofers will ensure good technical preparation and skilled installation of the zinc roof sheets.
Zinc roofing application uses a slightly different seam style to that of zinc cladding. When installing zinc cladding, the metal roofer will often use an angled seam (turned once and opposed to a double lock standing seam). This helps give a flatter appearance to the zinc sheets.
Zinc Roof Installation
Use a skilled zinc roofing contractor to ensure a high-end finish
Of all the different types of roof finish, zinc roof installation is possibly one of the most skilled. Installers must have good technical knowledge of zinc as a roofing material, along with a high level of artisan skill for the metal roof installation. Metal processing and handling of the zinc coils, coupled with correct folding and forming of the zinc, can take years to perfect. The Metal Roof Company can assist with your metal roof design and introduce you to known expert contractors across the UK and Ireland.
Design and final appearance
Zinc roof design will normally fall into two categories; a warm roof (unventilated) or a cold roof (ventilated). There are a number of important considerations to follow during the design process, including standing seam seam widths (distance between the standing seams), the detailing around penetrations such as Velux windows, soil vent pipes and the slope and elevation of the roof or façade.
