Estimating your roofing materials

A 36 m² roof slope needs roughly 360 large-format interlocking tiles, or about 2,160 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.

Before you order roofing materials

Check the minimum pitch

Every tile and slate has a minimum rafter pitch set by the manufacturer. A shallow extension roof may rule some tiles out.

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.

Getting roofing materials onto your Harpenden site

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
