Understanding the Required Roof Work

This project involves a full refurbishment of both flat and pitched roof elements, addressing waterproofing, insulation, and structural integrity. The extensive repairs ensure long-term durability, especially given Aberdeen’s exposure to wet and windy conditions.

Flat Roof Renewal Process

Replacing the flat roof on the front dormer and back extension involves several key steps:

  1. Removing the Existing Roof: The old lead roof will be stripped away.
  2. Assessing and Replacing Roof Boards: If necessary, damaged boards will be replaced to provide a solid base.
  3. Installing Bitumen Insulation Boards: These improve thermal efficiency and waterproofing.
  4. Applying Torch-On Felt Layers: A two-layer system of torch-on bitumen felt underlay followed by a black mineral cap sheet ensures maximum weather resistance.
  5. Re-slating Bottom Two Rows: This blends the repaired sections with the existing pitched roof.

Side-Slip and Slate Repairs

Side-slip renewal involves replacing deteriorated slates and side-wall protections to maintain a secure roof structure. This work is necessary for both the front and back dormers and will be done alongside Velux window replacement in the rear section.

Additionally, approximately 25–30 slate tiles across the entire roof will be repaired or replaced to prevent leaks and improve the roof’s longevity.

Lead Flashing and Chimney Work

Lead flashing around the dormer, chimney, and roof junctions is essential for preventing leaks. The work includes:

  • Replacing Dormer Lead Flashing: Installing Code 5 lead flashing to enhance durability.
  • Chimney Can Cement Work: Breaking out and renewing mortar around the chimney.
  • Renewing Chimney Breast Flashing: Ensuring a secure, watertight seal around the chimney base.

The total cost will depend on the scale of work and materials used. Approximate pricing includes:

  • Flat roof replacement (per m²): £80–£120

  • Lead flashing replacement (per section): £250–£600
  • Chimney cement work and flashing: £500–£1,200

The full scope of work may take:

  • 10–14 days for complete flat roof replacement.
  • 3–5 days for chimney and lead flashing work.
  • 3–7 days for slate repairs and dormer side-slip replacement.

Preparation for Roofing Work

Homeowners should prepare by:

  • Clearing access to the property for scaffolding and materials.
  • Informing neighbours about potential noise and temporary access restrictions.
  • Protecting any valuable items stored in the loft or upper rooms from dust and debris.

Does This Work Require Planning Permission?

Most roof repairs do not require planning permission unless:

  • The property is listed or in a conservation area.
  • Major structural changes are being made.

However, any significant modifications, such as adding insulation or changing roofing materials, must comply with building regulations.
