How much will you need?

A 48 m² roof slope needs roughly 480 large-format interlocking tiles, or about 2,880 small plain tiles, before ridge, hip and verge pieces. The exact count comes from the tile's gauge, so send us the roof measurements and pitch and we will work it out with the battens and membrane.

Delivering roofing materials in Harrow

Tiles and slates arrive palletised and are usually crane-offloaded where access allows; battens and membrane rolls travel with them. Harrow is inside our standard mainland delivery area.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Picking the right product

Fixing requirements

BS 5534 sets out how tiles must be fixed against wind uplift, which in most cases means every tile is mechanically fixed. Ask for the fixing specification with your tiles.

Matching an existing roof

The profile, size and colour all matter. A photo of the tile and a measurement of its exposed face help us find the closest current product.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Common questions from Harrow

What battens should I use?

Roofing battens graded for roofing work, of the size the tile maker and BS 5534 call for, normally treated.

Can I add other materials to my Harrow delivery?

Yes. Put everything on one list, from roofing materials to fixings and PPE, and we will price it as one delivery where the products can travel together.

Do you deliver roofing materials to trades and homeowners in Harrow?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can you match old clay tiles?

We can look for close current matches. Reclaimed tiles are another route for very old roofs; ask and we will tell you what we can source.
