Garage Roof Replacement Services
Abertawe Sectional Buildings Ltd provides full garage roof replacement services, including the safe removal of the existing roof and the fitting of a brand new one. We replace felt, corrugated metal, tiled or fibreglass roofing using high-quality, long-lasting materials.
Our skilled team works efficiently and tidily to minimise disruption and ensure an excellent finish.
Full Garage Roof Removal and Replacement
We safely remove the entire existing roof, dispose of waste responsibly, and install a new covering built to last. This is ideal for garages with widespread damage, rot, or age-related wear.
Our team handles the full replacement process with care and professionalism.
Flat Garage Roof Replacement
Flat garage roofs often suffer from water pooling and UV exposure. We remove the old covering and fit new rubber, felt, or GRP roofing designed for long term protection.
This gives a clean finish, better drainage, and a strong barrier against leaks.
Pitched Garage Roof Replacement
We replace tiled, slate, or corrugated pitched garage roofs with new coverings to match the original look or modernise it. Our service improves ventilation, weather resistance and visual appeal.
All work is completed with precision and attention to structural integrity.
Felt and Asphalt Roof Replacement
Old felt and asphalt roofs can crack and become brittle. We strip back the old surface, inspect the structure, and apply a high-quality replacement system that keeps out water and insulates effectively.
Great for both flat and slightly pitched garage roofs.
Corrugated Sheet Roof Replacement
We replace damaged or rusting corrugated sheets with modern alternatives like galvanised steel or fibre cement panels. These are highly durable, weatherproof, and available in a range of finishes.
We ensure a clean, secure fit with proper edge sealing and fastenings.
Insulated Garage Roof Installation
Improve garage usability year-round with an insulated roof replacement. We install thermal barriers under the new covering to regulate temperature, reduce condensation and damp, and help protect tools or vehicles stored inside.
It’s a practical upgrade for workshops or converted spaces.

When Should You Replace Your Garage Roof
Garage roofs should be replaced when they show serious signs of wear or damage. Common indicators include sagging rooflines, rotting timber supports, cracked membranes, and repeated leaks. You may also notice mould, interior staining or broken roof panels.
If your garage roof is over 20 years old or has been patched multiple times, replacing it could be more cost-effective in the long run.
A new roof can enhance insulation, improve appearance, and protect everything stored inside from the weather.
