Roof flashing plays a critical role in preventing water from penetrating vulnerable areas of your roof, such as around chimneys, skylights, valleys, and roof edges. When flashing is poorly fitted, damaged, or has gaps, water can easily find its way in, leading to recurring leaks and costly repairs. At Cannock Roofing Repairs, we understand that flashing faults are one of the most common causes of persistent roof leaks in Cannock and the surrounding areas. Identifying and addressing these gaps quickly is essential to maintaining the integrity of your roof.
Why Flashing is So Important
Flashing acts as a barrier that directs water away from joints and seams where different parts of the roof meet. Without properly installed and maintained flashing, water can seep under the roofing materials, causing rot, mould, and structural damage. Even a small gap can lead to a leak that keeps returning, even after temporary fixes.
Common Flashing Gaps That Cause Problems
Several flashing issues can lead to ongoing water ingress:
- Loose or lifted flashing – Strong winds or age-related wear can cause flashing to lift, leaving gaps where water can enter.
- Poor sealing at joints – Inadequate sealant or cracked mortar can allow moisture to penetrate.
- Incorrect overlaps – Flashing should be installed with the correct overlaps to direct water flow; improper fitting can leave pathways for leaks.
- Rust and corrosion – Over time, metal flashing can rust, weakening its effectiveness and allowing water through.
- Thermal expansion gaps – Seasonal temperature changes can cause flashing to expand and contract, creating small openings over time.
How to Spot Flashing Gaps Early
Homeowners can look for some early warning signs that may indicate flashing issues:
- Water stains or damp patches on ceilings and walls.
- Discoloured or deteriorated mortar around chimneys.
- Visible lifting or separation of flashing from the roof surface.
- Drips or leaks that occur during heavy rain, particularly around roof junctions.
Preventing Leak Recurrence with Proper Repairs
At Cannock Roofing Repairs, we recommend addressing flashing issues with professional repair work rather than temporary patching. Our approach includes:
- Thorough inspection of all flashing points.
- Removal of damaged sections and replacement with high-quality materials.
- Ensuring correct overlaps and secure fixing.
- Application of appropriate sealants for long-term waterproofing.
Seasonal Checks for Lasting Protection
Regular roof inspections, particularly after severe weather, can catch flashing gaps before they cause significant problems. In Cannock’s variable climate, this is especially important as temperature fluctuations and heavy rainfall can accelerate flashing deterioration.
