This Cork roofing project involved three natural slate dormer roofs that were experiencing leaks. Rather than carrying out isolated surface repairs, we stripped each affected dormer roof back to expose the failing membrane, inspected the roof beneath and rebuilt the roofing system with new breathable membrane and pressure-treated battens before reinstating the natural slate covering.

Repairing Three Leaking Dormer Roofs in Cork
Leaks around dormer roofs can be frustrating because the visible natural slates are only one part of the complete roofing system. On this property, all three dormer roofs required attention, and the work needed to go beneath the external slate covering to address the failing membrane below.
Our team began by inspecting the three dormer roofs individually before progressively removing the natural slates. This allowed the existing membrane and the roof construction beneath it to be exposed and properly assessed.
Rather than attempting to seal the problem from the outside, the affected roofs were stripped back so the defective roofing layers could be replaced as part of a more comprehensive roof repair in Cork.

Stripping the Natural Slates to Expose the Failed Membrane
The natural slate covering was carefully removed from the dormer roofs to expose the roofing membrane underneath.
A pitched slate roof contains several layers working together. Where the membrane beneath the slates has failed, simply addressing the visible surface may not deal with the underlying source of water ingress.

Checking Beneath the Failed Roofing System
After the slates and failed membrane were removed, we could inspect the exposed roof beneath.
This was an important stage because the dormer roofs had already been leaking. Stripping the roofing layers provided direct access to check the condition below and establish whether the water ingress had caused additional damage that needed to be addressed before the new roofing system was installed.
The photograph below shows one of the dormer roofs completely stripped during this inspection stage.
Where the cause or extent of a roofing problem is unclear, we also provide roof inspections in Cork to assess the roof before the appropriate work is recommended.

New Breathable Membrane & Pressure-Treated Battens
Once the dormer roofs had been stripped and inspected, we began rebuilding the roofing system.
New breathable membrane was installed across the prepared roof areas, replacing the failed material that had been exposed beneath the natural slates. New pressure-treated roof battens were then fitted over the membrane, creating the fixing structure required for the slate covering.
Why replace the battens as well?
The battens form the fixing structure for the slate covering above. As these dormer roofs were being stripped back and rebuilt, new pressure-treated battens were installed as part of the renewed roofing system rather than relying on the previous battens.
This gave the reinstated natural slate covering a newly prepared membrane-and-batten system beneath it.
What was included in this dormer roof project?
Three leaking dormer roofs inspected
Natural slate covering carefully removed
Failed existing membrane exposed
Roof beneath inspected for damage
New breathable membrane installed
New pressure-treated battens fitted
Natural slate roofing reinstated
All three affected dormer roofs renewed
THE PROJECT, EXPLAINED
Reinstating the Natural Slate Roof Covering
With the new breathable membrane and battens in place, the natural slate covering could be reinstated to complete the dormer roofing system.
Natural slate creates the visible external finish, but this project demonstrates why the materials beneath it matter too. The membrane and battens sit largely out of sight once the roof is complete, yet they form important parts of the overall pitched roof construction.
We provide slate and tile roofing services throughout Cork, including repair and replacement work where problems extend beneath the visible roof covering.

Three Dormer Roofs Properly Rebuilt
All three leaking dormer roofs were stripped back so the failed membrane could be addressed rather than covered over. After inspection, we installed new breathable membrane and pressure-treated battens before reinstating the natural slate roof covering.
THE PROJECT, EXPLAINED
What Can Cause a Slate Dormer Roof to Leak?
A leaking slate roof does not automatically mean that the natural slates themselves are the source of the problem. Water ingress can relate to damaged or displaced slates, flashing and junction details, or components beneath the visible roof covering.
That is why identifying the actual cause matters. On this project, stripping the dormer roofs exposed the failed membrane underneath and allowed the roofing system to be rebuilt rather than relying on repeated surface repairs.

Repairing Dormer & Slate Roofs Across Cork
We carry out pitched roof repairs, slate roofing work and more extensive roof replacements throughout Cork City and County.
Whether the issue involves an isolated damaged slate or deterioration beneath a larger section of roof covering, the appropriate repair depends on what has actually failed.
