JS Roofing provides professional flat roofing services for garages and property extensions across County Antrim. Based in Ballyclare, we carry out flat roof installation and replacement projects throughout Antrim, Newtownabbey, Glengormley, Templepatrick and surrounding areas.
Whether constructing a new extension or upgrading an existing garage roof, we install durable flat roofing systems designed for effective drainage and long-term weather resistance.
Flat roofing is commonly used for single-storey extensions due to its practical design and modern appearance. Proper installation is essential to ensure correct water runoff, secure membrane fitting and long-term structural reliability.
We inspect the supporting framework, install modern membrane systems and ensure correct edge detailing to prevent water ingress.

Garage roofs are frequently exposed to harsh weather conditions and can deteriorate over time. We install secure flat roofing systems suited to both attached and detached garages, ensuring dependable protection for vehicles and stored items.
Accurate membrane fitting and structural preparation are key to long-lasting performance.

Where existing flat roofs have deteriorated, full replacement restores protection and improves overall performance. Removing outdated materials and installing modern systems significantly reduces the risk of recurring leaks.
This approach supports wider property improvements and renovation projects across County Antrim.

Flat roofing systems require precise structural preparation and attention to drainage design. We ensure appropriate fall, secure membrane installation and correct flashing integration to maintain reliability in varying weather conditions.
Upgrading older systems improves durability and reduces long-term maintenance concerns.
