Check the manufacturer's mark, profile, dimensions, interlock and colour. Take an undamaged sample or clear measurements because visually similar tiles may not connect.
Tiled Roof Finishes for Extensions and New Builds
Roof tiles provide a repeatable covering for pitched roofs, with profile and interlock controlling how each course sheds water. MacBlair stocks tiles for new work and repair projects where pitch, appearance and structural loading have been checked.
Select the exact tile before setting out battens. The maker's minimum pitch, headlap, gauge and fixing pattern vary by model, and the laid weight must suit the roof structure. Coverage is based on the exposed area of each tile, not its overall dimensions.
Lay tiles over the specified roof membrane and graded tile battens. Use the required tile clips and fixings, then complete the roof with matching ridge tiles and approved verge details.
Roof Tiles FAQ's
It depends on the tile and gauge. Use the product's declared coverage at the selected headlap, then add allowances for cuts and breakage.
No, unless the manufacturer provides a tested alternative system for that exact product. A lower pitch increases the risk of wind-driven water entry.
The fixing schedule may require nails, clips or both, depending on product, roof zone and exposure. Follow the calculated specification.
Colour and surface texture can vary between batches and change with weathering. Mix tiles from several packs across the slope where the maker advises it.
