Roofing for Extensions & Conversions
JS Roofing provides professional roofing services for house extensions and property conversions across County Antrim. Based in Ballyclare, we work throughout Antrim, Newtownabbey, Glengormley, Templepatrick and surrounding areas, installing new roofing systems that integrate securely with existing structures.
With over 10 years’ experience in residential roofing, we ensure extension and conversion roofs are installed to modern standards for durability, ventilation and weather protection.
Professional Roofing for House Extensions
When building a house extension, the new roof must align correctly with the original property. Proper pitch, flashing, structural support and drainage design are essential to prevent long-term issues.
We install complete roofing systems for single-storey and multi-storey extensions, ensuring the new roof blends seamlessly with the existing structure while maintaining full weather resistance.
Roofing for Loft Conversions
Loft conversions often require alterations to the existing roof structure. We provide professional roofing installation for dormers and conversion projects, ensuring structural integrity, secure membrane installation and precise tile or slate fitting.
Careful detailing around junctions, valleys and roofline transitions ensures long-term reliability
Matching Existing Roof Materials
Where required, we carefully match existing roof tiles or slates to maintain visual consistency. This is particularly important when extending older properties where material blending is necessary to preserve overall appearance.
Correct installation and alignment help ensure the extension roof performs as effectively as the original structure.
Structural Preparation & Integration
Roofing for extensions and conversions requires attention to structural preparation. We inspect supporting timbers, ensure correct batten spacing and install breathable membrane systems to meet current performance standards.
Secure fixing systems and accurate ridge detailing complete the installation.
