What is the lifespan of the Rosemary tile?

Clay tiles like the Redland Rosemary tile have an incredibly long life and will last well past a generation.  Whereas a concrete tile has a lifespan of approximately 30-40 years, a clay tile will last 40-50 years or more.

The main problem for clay tiles is wear as the front edge of the tile gets worn down to a sharper edge and the tile themselves become more prone to leakage from both capillary action and breakages. Where a tile does get damaged, it will absorb moisture and become prone to further damage from the expansion/contraction of the water in temperature variations.

The longest lasting roofs are often slate and natural slate roofs can have a guarantee of 60-75 years. Unless they receive physical damage, slate roofs can last almost indefinitely.

What price are flat roof tiles?

Flat Roof tiles prices per square metre is a question that we get asked a lot but when it gets typed, can have two entirely different answers.

If you are asking about tiles for flat roofs, Promenade tiles and slabs are ideal for that purpose, providing a strong and hard wearing surface to go over the top of your EPDM or GRP covered flat roof.  Promenade tiles start at £1.38 (ex VAT) each for the Diamond Cut, Checkerplate and Striated Tiles, rising to £1.63 (ex VAT) for the beautiful Castile Riven Effect Promenade Tile.

The thicker Promenade slabs are a little more expensive starting at £2.50 (ex VAT) each. From there you choice is almost endless, with various finishes and multiple colours. The top of the range is the luxurious Castle Porcelain Stoneware Promenade Tile which is available in 13 colours and costs £20.49 (ex VAT) each.

The alternative meaning for the question is the price of roof tiles that are flat (rather than having a profiled surface like the Marley Mendip, Landmark Double Pantile or Renown Tiles)

We stock a large range of plain tiles which range in price from £0.31 to £0.77 each. Volume discounts are available so please call our websales team on 0333 700 11 11 for the most accurate estimate.
