Moor Park Surveyor Case Study: Roof Lantern Leak in Semi-Detached House, Moor Park, Blackpool
Property Overview
Located in the desirable Moor Park area of Blackpool, this semi-detached house offers a blend of modern amenities and suburban charm. The property features a recently added extension intended to provide additional living space and enhance the overall functionality of the home. However, during a comprehensive RICS Level 3 survey conducted in July 2024, a significant defect was identified in the extension’s roof lantern.
Inspection Findings
Upon detailed inspection, it was noted that the roof lantern, a contemporary feature intended to increase natural light within the extension, exhibits signs of water ingress. The presence of a leak was confirmed through visual evidence and moisture readings taken within the extension’s interior surfaces.
Key Observations:
1. Visible Water Stains: Water stains and damp patches were observed on the ceiling and walls directly beneath the roof lantern. These stains suggest an ongoing issue, likely exacerbated during periods of heavy rainfall.
2. Moisture Levels: Using a moisture meter, elevated readings were recorded in areas surrounding the roof lantern. These readings indicate that moisture penetration is more than superficial, potentially affecting the structural integrity of the materials involved.
3. Sealant and Flashing Deficiencies: Examination of the external sealant and flashing around the roof lantern revealed deterioration. Cracks in the sealant and poorly installed flashing are probable points of water entry.
Potential Implications
The leak in the roof lantern, if not promptly and effectively addressed, can lead to several serious implications:
1. Structural Damage: Persistent water ingress can weaken structural elements, including wooden beams and plasterboard. Over time, this can compromise the integrity of the extension.
2. Mold Growth: Damp conditions are conducive to mould growth, which poses health risks to occupants and can be costly to remediate.
3. Decreased Property Value: Unresolved water ingress issues can detract from the property’s market value and complicate future sale transactions.
Moor Park Surveyor Recommended Remedial Actions
To rectify the identified defect and prevent further deterioration, the following remedial actions are recommended:
1. Professional Roof Lantern Inspection and Repair: Engage a certified roofing contractor with experience in roof lantern installations. The contractor should assess the extent of the damage and repair or replace the defective sealant and flashing. Ensuring a watertight seal is paramount.
2. Interior Repairs: Once the source of the leak is rectified, repairs to the interior surfaces, including plastering and repainting affected areas, should be undertaken.
3. Regular Maintenance: Implement a routine maintenance schedule to inspect and maintain the roof lantern and surrounding roofing elements. This proactive approach will help identify and address potential issues before they escalate.
Conclusion
While the presence of a leaking roof lantern in the extension of this semi-detached house in Moor Park area is a significant concern, it is a remediable issue. Addressing the leak through professional repair will restore the extension to its intended function and prevent further damage. Prospective buyers should factor in the cost of repairs and potential disruption when considering this property. Nonetheless, with appropriate intervention, the extension can continue to serve as a valuable addition to the home.
