Western Red Cedar Roof Shingles – No.1 Blue Label Grade, 2.49m² Pack

Most UK roofs are finished in fired clay or concrete, which is exactly why a cedar-shingled roof stands out on the street it sits on. These are genuine western red cedar wood shingles, No.1 Certigrade Blue Label grade – the premium classification, cut entirely from clear heartwood with no sapwood or significant defects – supplied treated for extra protection against rot and decay. Cedar shingles are a specialist, low-volume choice in the UK market compared with clay, concrete or slate, which is exactly the point for a period property, a garden building, a lodge roof or a cladding project where a natural timber finish matters more than following the crowd. Left untreated they weather to a soft silver-grey over years; this treated pack helps protect that transition for longer. Key benefits No.1 Certigrade Blue Label grade – 100% heartwood, 100% clear, 100% edge grain, no significant defects Genuine western red cedar: naturally insect and rot resistant, with added preservative treatment Highly insulating and lightweight compared with mineral roofing materials Sold by fixed roof-coverage pack (2.49m²), so you can order to your measured area 30-year manufacturer warranty (terms apply) Specification Material Western red cedar, preservative treated Grade No.1 Certigrade Blue Label Shingle length 405mm (16-inch) Shingle width Random widths, 75–350mm Coverage per pack 2.49m² fixed on the roof Suitable pitch 14° to 90° Warranty 30 years (terms apply) Ordering & installation guidance Measure your total roof area and order enough packs to cover it, remembering that the 2.49m² coverage figure already accounts for the correct exposure/lap for shingles fixed at a standard pitch – always check your fitting instructions for the pack quantity needed at your specific pitch before ordering. A breathable sarking board is recommended beneath cedar shingles on a timber-frame roof deck; see our wood fibre sarking & insulation board for a suitable breathable substrate. Roughly 1kg of shingle nails is needed for every six packs – source stainless or silicone bronze nails to avoid staining the cedar. FAQs Will the shingles stay this colour? No – western red cedar naturally weathers from its fresh honey-brown tone to a silvery grey over a period of months to a few years, depending on exposure. This is normal and part of the material's character; the preservative treatment helps protect the timber through that process rather than fixing the colour. What nails should I use? Stainless steel or silicone bronze nails are recommended to avoid staining or corrosion streaking on the cedar; standard galvanised nails are not advised for a long-term roof. Can this be used for wall cladding as well as roofing? Blue Label is the premium grade and is suitable for both high-end roofing and wall cladding applications, though fixing details differ – confirm cladding-specific fixing centres with your installer. What roof pitch is this suitable for? 14° to 90°, covering everything from a shallow-pitch garden building roof through to a steep traditional roof or vertical cladding application. Do I need an underlay beneath the shingles? Yes, a breathable roofing membrane or breathable sarking board over the rafters is standard practice beneath timber shingles to manage any incidental moisture – see the cross-linked sarking board above.
