Conservatory Lead Flashing Repair in Crawley RH10
We have a 25-year-old UPVC conservatory with an insulated roof that is maintained annually. However, during recent heavy rainfall, we noticed water ingress at the main join to the house where it is bedded in lead flashing. We need an expert to assess and reseal the area. Can you assist?
Expert Advice on Conservatory Lead Flashing Repairs
Lead flashing is essential for sealing the joint between a conservatory roof and the main house to prevent water ingress. Over time, flashing can deteriorate or loosen due to weather exposure, leading to leaks. Addressing this promptly ensures your conservatory remains watertight and protected from further damage.
Steps to Repair Lead Flashing
The repair process typically involves:
- Inspection: Assessing the flashing for cracks, gaps, or loosening to determine the root cause of the water ingress.
- Cleaning: Removing debris, old sealant, or dirt from the flashing and surrounding surfaces to ensure a proper seal.
- Rebedding the Flashing: Re-securing the lead flashing with lead wedges or clips and bedding it in fresh mortar if necessary.
- Sealing: Applying a high-quality lead sealant to fill gaps and create a waterproof bond between the flashing and the wall.
- Testing: Simulating rainfall to verify the effectiveness of the repair.
Materials and Techniques
Durable materials and precise techniques are essential for effective repairs:
- Lead Sealant: Specialised sealants designed for lead flashing ensure long-lasting waterproofing.
- Mortar: A weather-resistant mix for rebedding flashing where required.
- Lead Flashing: Replacement flashing may be necessary if the existing material is significantly damaged.
Cost and Timeline
The cost for lead flashing repairs typically ranges from £300–£600, depending on the extent of the damage and materials required. The repair process usually takes 1–2 days, including assessment and testing.
