What the job involves

Chimney flashings are the metal (usually lead) sheets that seal where the chimney stack meets the roof surface. They are the single most common leak source on UK pitched roofs because the stack moves slightly with thermal expansion and the flashings fatigue over decades.

A proper re-lead job chases out the existing lead from the mortar joint, dresses new code-4 or code-5 lead around the stack, and bedded it back in with fresh mortar. Shortcuts — silicone over old failing lead, for example — are not durable.

Sunderland — local context

Traditional material: Welsh slate on Victorian terraces, concrete post-war.

Coastal exposure accelerates lead and nail corrosion on seaward-facing elevations; Ashbrooke and Grangetown contain conservation areas with material restrictions.

What changes the price

  • Stack size and whether all four faces need re-leading.
  • Scaffold requirement (almost always for chimney work above the first floor).
  • Whether the brick pointing underneath is also failing and needs repointing.
  • Whether the cowl and pot are sound or need replacing at the same time.

Timeline: Usually 1–2 days on site plus scaffold hire time.

Common questions

How long should new lead flashing last?

Code 4 or 5 lead flashing, properly dressed and bedded, has a service life of 60–100 years on a UK domestic chimney. The failure mode is usually the mortar bed, not the lead itself.

Can I use silicone or flashing tape as a cheaper option?

Those products have a place for temporary repairs and for flat surfaces that don’t flex, but they’re not a long-term substitute for dressed lead on a chimney. A good roofer will quote the proper repair and explain why.

What does chimney or flashing repair typically cost in Sunderland?

A typical chimney or flashing repair job in Sunderland falls in the £330–£1,400 range, with the middle of the market around £650. Sunderland’s labour and access factor (0.93× the national baseline) means prices run slightly below the UK average. Actual quotes vary with access, materials, and specifics of the job.

Are there any Sunderland-specific things that affect price?

Coastal exposure accelerates lead and nail corrosion on seaward-facing elevations; Ashbrooke and Grangetown contain conservation areas with material restrictions.
