Frequently Asked Questions

Leadwork refers to traditional sheet lead detailing used for waterproofing and finishing.

It is commonly used in:

• flashings at walls and chimneys
• valleys and junctions
• roof penetrations
• complex transitions and custom details

Lead is highly durable and well suited to long-life heritage roofing when installed correctly.

Lead is typically used for:

• flashings (chimneys, walls, parapets)
• valleys and junctions
• heritage detailing where traditional methods are required

It is chosen because it forms to complex shapes reliably.

Lead is safe when used correctly in roofing applications. The key is:

• professional handling during installation
• correct detailing and fixing
• responsible collection and recycling of offcuts

We follow safe work practices when working with lead.

Lead is one of the longest-lasting roofing materials when installed correctly. It is often specified for heritage work because it can perform for decades with minimal intervention.

In many cases, yes. Matching depends on the original material and availability.

We consider:

• size and thickness
• colour and texture
• installation pattern
• fixing method and detailing

Where an exact match is not possible, we recommend the closest suitable alternative. For material guidance, refer to Products.

A natural slate roof can last 75 years or more when installed correctly.
Lifespan depends on:

• slate grade and thickness
• correct fixing and detailing
• periodic inspections of flashings and valleys

Slate is often chosen because it can be a long-term, generational roof system.

Slate itself needs very little maintenance. Most attention is on the components around it:

• flashings and valleys
• ridges and junctions
• occasional replacement of a cracked or slipped slate

A simple inspection schedule helps keep everything performing as intended.

Slate is heavier than metal roofing. If your home was built for tiles or slate, it is often suitable.

If you are changing from a lighter roof type, we will check structure and loading requirements before proceeding.

Slate roofs can often be repaired if the overall system is still sound.

Repairs are common where there is:

• localised damage
• slipped or broken slate
• aged flashings causing leaks
• isolated fixing failures

If widespread failure is present, a full replacement may be the more reliable solution. We assess this during inspection.
