GRP Dormer Roofs

Adding a roof dormer to a newly built property can give it instant curb appeal, so why not add a GRP Dormer Roof to every home on your project or housing development? Imagine every home on your project or housing development proudly boasts a gabled dormer or a sleek GRP window roof, creating the perfect architectural finish.

Stormking’s expertise lies in providing fully assembled GRP Dormer roofs, tailored to fit various designs and easy installation. Whether you’re considering a traditional dormer or the more distinctive gabled dormer, our selection caters to a range of roof angles, finishes, and window sizes. Our GRP dormers seamlessly integrate with any style, ensuring that the desired dormer configuration is achieved.

The Government has recently introduced revisions to Part L of the Building Regulations, specifically to new constructions commencing from June 2023. The latest update to Part L aims to improve the efficiency of a building even further by introducing new standards for building elements, particularly walls and roofs.

Our WarmaDorma© dormer window, created over a decade ago, was specifically tailored to address the growing need for enhanced thermal performance in dormers. This innovative design has allowed us to seamlessly adapt our dormer ranges to meet the requirements of the recent regulation change, without major modifications to our production methods.

As well as saving installation time, these units offer an excellent, sustainable alternative to conventional building materials. The advantage of choosing our GRP dormer roofs extends to their manufacturing and installation. Crafted using cutting-edge techniques in GRP fabrication, our GRP dormer range is not only lightweight but durable too.

One of the standout features is the offsite manufacturing process. Our prefabricated dormers are designed and manufactured in-house and delivered shrink-wrapped, as a full unit to allow for a swift and stress-free installation on-site.

Whether you have a clear vision for your traditional style dormer or looking into alternative designs such as the GRP gabled dormer, our team is on hand to help. Please get in touch today about your GRP dormer roof requirements.

BBA Accreditation Certification

All Stormking dormer ranges are manufactured to strict guidelines and production criteria, ensuring a quality product every time. For extra peace of mind all dormers carry BBA Accreditation, one of the highest levels of third-party construction certification available in the industry.
