Hole Repair in Slate Roof Near Chimney in Derby
There is damage (a hole) to the front pitched slated roof near the chimney, and another hole on the side of the roof just above the guttering. Both need to be repaired, and the side one is accessible by ladders.
Why Immediate Repair of Roof Holes Is Crucial
Even small holes in a slate roof can lead to major problems if not repaired promptly:
- Water ingress: Rain can easily penetrate through holes, leading to damp, mould, and ceiling stains.
- Structural damage: Moisture can rot timber roof supports and compromise the roof’s integrity.
- Pest intrusion: Openings can allow birds or insects into the loft space.
- Heat loss: Gaps in the roof reduce insulation, increasing energy bills.
Likely Causes of Roof Holes in Pitched Slate Roofs
The damage near the chimney may have been caused by:
- Falling debris or dislodged flashing during storms.
- Cracked slates from age or frost expansion.
- Chimney movement leading to slate displacement.
The hole near the guttering is often due to:
- Slipped slates at the eaves due to worn fixings.
- Water overflow from blocked gutters weakening the slate edges.
How the Roof Holes Will Be Repaired
Professional roofers will follow these steps:
- Inspection: Assess both holes and surrounding slate condition.
- Slate removal: Carefully lift and remove damaged slates and debris.
- Underlayment check: Repair or replace any torn felt or membrane beneath.
- Slate replacement: Fit new or reclaimed matching slates securely.
- Repoint chimney flashing (if needed): Reseal any loose or damaged flashing.
- Final sealing and leak check: Ensure watertight finish.
