Roofing Buying Guides: Choose Compatible Materials
Roof tiles, slates and the right roof covering
Start with the building design, roof pitch and exposure before choosing between roof tiles and roof slates. For concrete and clay options, explore Marley roof tiles and Redland roof tiles. Check the manufacturer's permitted pitch, fixing schedule and compatibility with the roof's supporting structure.
Roof junctions: ridges, hips, valleys and verges
Allow for specialist roof fittings at every change in roof geometry. Browse ridge tiles and fittings, hip tiles, valley tiles and gable tile fittings. Match each fitting to the exact covering and installation system.
Weatherproofing and ventilation
Review lead flashing at appropriate roof junctions, roof ventilation products where required by the design, and dry fix roofing systems for suitable applications. Complete the project with compatible roof accessories and fascias, soffits and guttering.
Roofing FAQs
Can I mix roof fittings from different manufacturers?
Only where technical compatibility has been confirmed. Similar colours and shapes do not prove that fittings work together.
How do I calculate roof tile quantities?
Measure the roof areas and use the manufacturer's installed coverage rate, allowing for pitch, laps, cuts and specialist fittings.
Should I order ventilation products with my roof covering?
Ventilation requirements depend on the roof build-up and design. Confirm the specification before purchasing.
