I’m looking for a quote/assessment for a black mould area in my bedroom, which measures approximately 3×3 inches and has been there for around a year. I suspect that there may be a leak in the roof somewhere. The property is a three-storey townhouse. Please call to arrange an inspection.

Assessment and Repair of Suspected Roof Leak in Quedgeley, Gloucester

Signs of a Roof Leak in Townhouses

Finding black mould inside a home, especially in upper floors, is often a sign of moisture ingress from a roof leak. In three-storey townhouses like those in Quedgeley, Gloucester, leaks can occur due to aging materials, storm damage, or poorly sealed roof penetrations such as vents or chimneys.

Potential Causes of Roof Leaks

The most common causes of roof leaks that could lead to mould growth include:

• Damaged or missing roof tiles: Cracked or displaced tiles can allow water to seep through.
• Blocked or leaking gutters: Poor drainage can cause water to back up and penetrate the structure.
• Worn flashing: Around chimneys or roof junctions, flashing can deteriorate over time.
• Condensation issues: Inadequate loft ventilation can lead to damp conditions that mimic a roof leak.

Steps to Diagnose and Repair the Leak

A professional roofing contractor will follow these steps to assess and fix the problem:

1. Visual Inspection: Examining the roof externally for obvious signs of damage.
2. Internal Inspection: Checking loft spaces and ceilings for moisture ingress points.
3. Moisture Testing: Using moisture meters to confirm water penetration.
4. Repair Work: Replacing damaged tiles, repairing flashing, or improving ventilation if needed.
5. Mould Treatment: Cleaning and treating affected areas to prevent recurrence.

Estimated Costs for Roof Leak Repair

The cost of diagnosing and repairing a suspected roof leak can vary depending on the extent of the damage. Typical costs in the Gloucester area include:

• Roof inspection: £100 – £300
