Quickslate

British Lead Quickslates provide a simple but effective weatherproofing solution where a pipe penetrates a roof covering.
They consist of a rubber cone vulcanized on to a Lead slate base, manufactured from Code 4 Rolled Lead Sheet. The malleability of the Lead base means that unlike similar products that employ aluminium or hard metal bases, British Lead Quickslates can be easily shaped or dressed to suit almost any roof profile.

British Lead Quickslates can be easily shaped or dressed to suit almost any roof profile.
They are used where flue pipes and soil stacks penetrate slate, tile, felt and asphalt covered roofs. Quickslates are also suitable for gas flues, withstanding temperatures of 150°C. Available to suit flat roofs with vertical outlets and 30º - 40º pitched roofs. Quickslates suit most pipe diameters up to 125mm.
  • Provides a weathertight joint
  • Saves welding
  • Easier to fit than aluminium and zinc
  • No maintenance required
  • Cut the rubber to suit your pipe diameter
  • Always cut the aperture in the rubber slightly smaller than the required diameter to ensure a weathertight fit
  • Use a water based lubricant or silicone grease to lubricate the neck of the rubber sleeve of the Quickslate prior to fitting
  • British Lead Quickslates are coated with Patination Oil when the lead is cut and therefore the Quickslate itself will not need further coating. This is because using Patination Oil on Quickslates can damage the rubber.
  • Take care not cut outside of the outer ring or into the wall of the upstand
Dimensions and packaging:
  • Base dimensions: 450mm x 450mm and min upstand height 150mm
  • Pipe sizes: Can be cut to suit a range of outside pipe diameters up to 125mm

Quickslate ‘How To’ Video Transcription

Below is a transcription of a video shot by British Lead with Tim Fuge, Young Leadworker of the Year 2016, on the correct way to install Quickslate.
Tim Fuge:
Hi, my name is Tim Fuge and we're here at the LSTA Training Centre in Kent to bring you the latest British Lead guide to installing Quickslates.

Why Use Quickslates on a Roof

Tim Fuge:
BLM Quickslates provide a simple but effective weatherproofing solution where a pipe penetrates a roof. They can be used on tile, slate, felt, and asphalt roof coverings. BLM Quickslates are made by vulcanizing a rubber cone onto a 450 mm square Code 4 Rolled Lead Sheet base. The flexibility of the rubber upstand means they suit pipes with diameters up to 5".  Available to suit flat roofs with vertical outlets and 30º - 40º pitched roofs. Quickslates are suitable for use with gas flues withstanding temperatures up to 150 degrees Celsius.

Tim Fuge:
For preparation, firstly we need to find the pitch of the roof to ensure we're using the correct slate. In this example, our pitch is 34 degrees. A welted check edge should be detailed along the top edge of the slate base to prevent any driven rain bypassing the top of the slate in storm conditions.

When to apply Quickslate to Lead Roof

Tim Fuge:
The rubber cone comes sealed providing users with the flexibility to cut an outlet to suit the pipe diameter. Handy rings give guidance to increasing outlet diameters up to a maximum of 125 mm or 5" at the outer ring. Careful cutting of the rubber cone is required. Ensure that no cuts are made outside the outer ring or in the wall of the upstander as this will cause the rubber to tear when stretched over the pipe. Use a water-based lubricant or silicone grease to lubricate the inside neck of the rubber upstand prior to sliding over the pipe. Never use washing-up liquid as this can cause the rubber to deteriorate.

Tim Fuge:
The Quickslate is then placed over the pipe and into position. Roof tiles should be fitted as close to the pipe as possible. The vent cowl can be secured using solvent cement to finish off.
