Roof Flashing Repair Dublin

Flashing is one of the most critical components of any roofing system. It protects vulnerable junctions such as chimneys, skylights, roof valleys, and wall connections from water ingress. When flashing fails, leaks are almost inevitable. That’s why we offer reliable roof flashing repair services in Dublin — to keep your home watertight and protected year-round.

​

At StoneMac Home Improvement Services, we specialize in detecting and repairing all types of flashing damage, serving both residential and commercial properties across Dublin, Wicklow, and Kildare.

What is Roof Flashing?

 

Roof flashing is a thin layer of metal (usually aluminium, lead, zinc, or copper) installed at roof joints to direct water away from critical areas. It’s commonly found around:

​

• Chimneys
   

• Dormers
   

• Skylights
   

• Roof valleys
   

• Vent pipes
   

• Wall junctions
   

If flashing becomes loose, cracked, or corroded, water can seep into the structure — causing damp, rot, or structural damage.

Common Signs You Need Flashing Repair

​​

• Leaks or water stains on ceilings and walls
   

• Rusted or visible gaps in flashing
   

• Detached flashing around roof features
   

• Loose mortar or cracked sealant near chimneys
   

• Water pooling in valleys or near skylights
   

• Drafts entering through attic or roofline
   

Spotting these issues early can prevent major roof repairs down the line.
