Britmet LiteSlate Synthetic Plastic Slate – Pack of 22 (All Colours)

Britmet LiteSlate is a lightweight synthetic roofing slate designed to recreate the appearance and character of traditional natural slate without the weight, fragility or specialist cutting requirements. Supplied in packs of 22 slates, LiteSlate is suitable for roof pitches from 14.5° to 90° and is ideal for extensions, garden rooms, outbuildings, garages, porches, renovations and new-build roofing projects.

Manufactured from a recyclable blend of polypropylene and limestone, Britmet LiteSlate combines an authentic slate appearance with the practical advantages of a modern synthetic roofing material. Each slate features a realistic textured finish and riven edges, providing the appearance of traditional slate while being considerably easier to handle, cut and install.

Unlike natural slate, Britmet LiteSlate synthetic slates will not crack, break, chip or delaminate during normal handling and installation. At approximately 0.6kg per slate and around 12kg per m² when installed, LiteSlate is also an excellent option where reducing the overall roof covering weight is important.

How Many Britmet LiteSlate Slates Do I Need Per Square Metre?

The number of Britmet LiteSlate roof tiles required per square metre depends on the pitch of the roof.

These coverage rates apply to fully boarded or felt-and-batten roof constructions.

How to Calculate How Much Britmet LiteSlate You Need

First, calculate the area of your roof in square metres:

Roof Length (m) × Roof Width (m) = Roof Area (m²)

You can then use the appropriate coverage rate for your roof pitch to calculate the number of slates required.

Example:

For a roof measuring 5m × 3m with a 24° pitch:

5m × 3m = 15m²

At 24°, approximately 22 LiteSlate tiles are required per square metre:

15m² × 22 slates = 330 slates

As each pack contains 22 slates:

330 ÷ 22 = 15 packs

You would therefore require approximately 15 packs of Britmet LiteSlate before allowing for cuts and wastage.

Allowing for Cuts and Wastage

The calculations above are an estimated guide based on the exact coverage figures provided by the manufacturer and do not include additional material for cuts or wastage.

It is standard roofing practice to allow approximately 5% to 10% additional material, depending on the complexity of the roof and the experience of the installer.

The final quantity ordered remains the responsibility of the customer or installer.

Is Britmet LiteSlate Suitable for Low-Pitch Roofs?

Yes. Britmet LiteSlate can be installed on roofs with pitches as low as 14.5°, subject to the correct roof construction and installation method.

This makes LiteSlate particularly useful for lower-pitched extensions, garden rooms, porches and other projects where the pitch may be unsuitable for some traditional slate roofing systems.

LiteSlate can also be installed on roof pitches up to 90°.

Is Britmet LiteSlate Easy to Install?

Britmet LiteSlate has been specifically designed to simplify installation.

Each synthetic slate includes visible fixing locations, pre-installed spacers and lapping guides, helping installers achieve the correct positioning and overlap.

Only two fixings are required per slate.

LiteSlate can also be cut using a sharp fine-tooth saw or suitable sharp blade, removing the need for specialist natural slate cutting equipment. This makes it suitable for experienced roofing contractors as well as competent DIY installers undertaking smaller roofing projects.
