Flat Roofing in Giffnock for Extensions
Giffnock Roofing Specialists Ltd provides flat roofing solutions for extensions connected to existing pitched roofs across Giffnock and surrounding areas.
Unlike standard flat roof installation, extension roofing depends heavily on the junction between old and new structures. We focus on correct detailing, drainage, and weatherproofing to ensure the connection performs properly over time.

what we do
Flat Roofing for Extensions Requires the Junction Done Properly
Many flat roof failures do not begin with the flat roof surface itself, but where the extension meets the original pitched roof. This connection needs careful planning to manage water flow, flashing, and movement between two different roof structures.
Across Giffnock, Clarkston, and Newton Mearns, many traditional homes have been extended over time. These extensions require roofing solutions that respect the existing slate or tile roof rather than treating the new section separately.
While the extension itself may be relatively modern, the connection point to the original roof is not always designed with long-term water movement in mind.
We regularly see issues such as:

how we work
Our Approach to
Extension Flat Roofing
We provide reliable flat roofing solutions, from repairs and replacements to new installations, designed for lasting protection and performance.
1.
Inspect the Existing Roof
We assess the flat roof, pitched roof, flashing, drainage, and previous repairs.
2.
Identify the Real Cause
We determine whether the issue comes from the membrane, drainage, or junction detailing.
3.
Plan the Correct Solution
Repairs or replacement are recommended based on the actual condition of the roof.
4.
Complete the Work Properly
Access, weather protection, and connection details are carefully managed throughout the project.
Why the Flat Roof Junction Matters
A flat roof can be installed to a high standard and still fail if the connection to the existing roof is wrong..
In most cases, water problems happen because:
We treat the extension and the original roof as one connected system, not two separate structures.
