Before & After – Rear Extension Roof Replacement

This rear extension had been experiencing persistent leaks due to the original roof being installed with incorrect materials.

The roof has a 10° pitch, however the previous contractor installed cement fibre slates and standard Velux roof windows. Standard Velux windows are designed for roof pitches of 15° and above, while cement fibre slates typically require a minimum pitch of 20°. As a result, the roof was not suitable for the materials used and was unable to perform effectively.

Our solution:

Installation of new roofing felt and treated battens

Centurion low-pitch tiles, suitable for a 10° roof

A low-pitch roof window specifically designed for this roof angle

New lead aprons

New lead verges

Dry verge system for a durable, maintenance-free finish

Ensuring the correct specification is just as important as the quality of workmanship. Using appropriate materials for the roof pitch is essential to achieving a watertight and long-lasting installation.

If you are experiencing leaks or have concerns about your roof, contact D.J. Mackay Roofing Ltd for honest advice and a professional inspection.
