For centuries, slate roofing has been desired for its durability and beauty. With authentic surfaces and edges, TapcoSlate highlights the handsome character of slate, at the same time enhancing roof performance through innovative design. Unlike natural slate, TapcoSlate won’t break or delaminate and comes with a 40-year Warranty.

BBA Certified TapcoSlate gives you the power to evoke both historical elegance and outstanding modern-day style. Our slates are created with moulds cast from real slate to capture genuine peaks, plateaux and curves. Colour-through design and UV stabilisation ensure “stay-true” richness for traditional colours such as Pewter Grey and Plum, bold tones like Brick Red and unique selections such as Emerald Green and Grey/Black blended tiles.

TapcoSlate Mixes are another feature of our unique colour choices, they deliver uncommon elegance through boldly-appealing multiple colours to turn your roof into a work of art

TapcoSlate Key Features:

  • Made from resin bonded, crushed virgin Dolomite limestone, TapcoSlate has the random texture and edges of natural slate.
  • TapcoSlate is lightweight, (from only 12 kgs/sq. metre), easy to handle and can be fixed by either hammer and nail or nail gun.
  • Strong, cost effective, recyclable and attractive.
  • No breakage, wastage, drilling or sorting required.
  • Available in a range of attractive colours and blends.
  • A production-induced camber ensures a tight fit at the tail of the slate when fixed.
  • TapcoSlates have excellent weathering characteristics; they will not curl, lift or delaminate, and are impermeable to water.
  • When tested to BS476 part 3, an AA fire rating is achieved for installation on boarded roofs.
  • BBA Certified.
  • TapcoSlates are backed by a 40-year Warranty.


TapcoSlate Key Benefits:

  • Looks extremely authentic.
  • Choice of colours.
  • Traditional colours (5 in total) are stocked and available within 4-5 days. (Alternative and Mix colours are subject to a 5-6 week delivery time – but this isn’t long when planning roofing/building work – and a minimum order quantity.)
  • Minimal Wastage. Breakage is negligible when handling/cutting/fixing. Natural slate may incur 5-15% breakage/shrinkage factor depending on the quality.
  • Lightweight… from only 12 kgs/sq. metre (half the weight of natural slate). Very useful for re-roofing applications where timbers may be suspect, or when designing the loading specification for a new roof.
  • Slates are marked with nailing and exposure guidelines and horizontal spacers, which helps to maintain integrity when fixing.
  • Dimensionally accurate… no need to sort for thickness before loading the roof. Natural slate can vary in thickness, causing gapping, and subsequent breakage if walked on.
  • Packs of 25 mean easier handling and quicker roof loading.
  • Product doesn’t crack or split, particularly when cutting for hips, valleys, etc.
  • Quicker to lay than natural slate. Much loved by roofers, once they have used the product, for many of the above reasons.

The sturdy board will resist water damage and biological attack with a service life that is in excess of 20 years in normal conditions.

Internally we offer two options:

Option 1- installation of UPVC cladding which offers a clean finish and less maintanence also reflecting much of the light so brightens the room up on those sunny days.

Option 2 – a 9.5 Plaster board fixed to the conservatory roof batten. The plasterboard comes with a vapour control layer which is laminated with a film back liner and silver metallise polyester making it resistant to moisture and water damage. We then offer our services to skim the plaster boards or you can choose to hire your own plasterer and finish at your own leisure.
