Garage Flat Roof Repair in Nottingham for Leaking Felt Roof

Flat Garage Roof Repair in Nottingham

My garage roof is leaking, and it’s a flat roof with wooden panels on the sides that also need replacing. The current roof is made of felt, but the entire roof requires repair. I am the property owner, and the garage is part of a semi-detached property built between 1970 and 2000. The roof is on the first floor. I would like the materials supplied and the repair carried out as soon as possible. — Gareth, Nottingham (NG9)

Understanding the Problem: Leaking Flat Roof

Flat roofs, while practical and cost-effective for garages, can be prone to issues over time, especially when roofing felt is used as the covering material. Gareth’s description points to several problems, including a leak in the felt layer and damaged wooden panels on the sides. The issues suggest prolonged exposure to water or weather conditions has compromised the roof’s integrity.

Common Causes of Leaks in Flat Felt Roofs

Leaks in flat roofs often occur due to:

  • Weather wear: Sun, rain, and frost can degrade roofing felt over time, causing cracks or splits.
  • Poor drainage: Flat roofs can suffer from water pooling, accelerating wear and leaks.
  • Age: With the property built between 1970 and 2000, the existing roof might have reached the end of its lifespan.

Steps to Repair a Flat Felt Garage Roof

Repairing this roof requires the following steps:

  1. Inspection and assessment: A thorough inspection will identify the extent of damage to the felt and wooden panels.
  2. Removal of the existing felt: Stripping off the old felt ensures a solid base for new materials.
  3. Repairing or replacing wooden panels: Damaged panels must be replaced with weather-resistant timber to ensure structural integrity.
  4. Installing new felt: High-quality torch-on or self-adhesive felt is applied in layers, ensuring a watertight seal.
  5. Finishing touches: Edges and joins are sealed to prevent water ingress, and drainage is improved if needed.

Materials Needed

The repair requires materials such as:

  • Roofing felt (torch-on or self-adhesive)
  • Weather-resistant timber for side panels
  • Bitumen adhesive and sealant
  • Roofing nails and fasteners

Estimated Costs and Duration

Flat roof repairs typically cost between £40-£70 per square metre. For a standard single garage, the total cost may range from £600-£1200, depending on materials and labour. Repairs usually take 1-2 days.

Why Timely Repairs Are Essential

Ignoring a leaking flat roof can lead to:

  • Structural damage: Water ingress can rot wooden supports and weaken the garage.
  • Mould and mildew: Damp conditions encourage unhealthy mould growth.
  • Increased repair costs: Delayed repairs often mean more extensive and expensive fixes later.

Choosing Quality Materials

Using high-quality roofing felt such as products from IKO or Bailey ensures a durable and long-lasting repair. These brands are widely available in Nottingham from suppliers like Wickes or Travis Perkins.

Preparing for the Repairs

Homeowners should clear the garage of valuables and ensure easy access for roofers. Safety measures will also be necessary, particularly if the garage roof is adjacent to other structures.
