Expert New Roof Trusses & Joists in Neath & South Wales

The structural foundation for a safe, secure, and perfectly level roof.

The strength of any roof lies in its hidden framework. Whether you are embarking on a new build project or extending your current home, the installation of roof trusses and floor joists is a critical phase that demands absolute precision. We combine master-grade carpentry with modern structural engineering to ensure your property’s “skeleton” is built to last.

Our team specialises in both traditional “cut and pitch” roofing and the installation of modern pre-fabricated trusses. Serving Neath and the wider South Wales region, we understand that our local weather requires structures that can handle high wind loads and heavy rainfall. We don’t just “put wood up”; we engineer a timber solution that ensures your roofline remains straight and your ceilings stay secure for decades.

From complex attic-room joists to standard gable trusses, our structural carpentry provides the peace of mind that your home is supported by the very best in the trade.

Comprehensive Structural Timber Solutions

Engineered trusses, floor joists, and bespoke site-cut roofing.

Our comprehensive approach ensures that every timber element is designed to work in harmony with the rest of your build. We manage the process from the initial measurements to the final bracing, ensuring a “roof-ready” finish.

Why Choose Professional Roof Carpentry?

Precision engineering, high-grade timber, and structural integrity.

A roof is only as good as the timber supporting it. Incorrectly spaced joists or poorly braced trusses can lead to sagging rooflines, cracked plasterboard, and, in extreme cases, structural failure. By choosing a team that understands the intersection of carpentry and roofing, you ensure a seamless transition from the timber frame to the final slate or tile.

In South Wales, where older properties often have “settled” walls that aren’t perfectly square, our ability to hand-cut rafters on-site is a game-changer. We ensure that every joint is tight and every span is calculated to meet current UK Building Regulations.

We only use C24-graded timber for maximum strength and load-bearing capacity.

Expert hand-cutting of rafters for unique roof shapes and historic property restorations.

Using advanced levelling tools to ensure your roof is perfectly flat for the roofing team.

Efficient truss delivery and crane-assisted lifting for rapid site progress.

Roof Trusses & Joists FAQs

Expert advice on your structural timber framework.

We know that structural work can feel daunting. To help you understand the process of framing your new roof, we have answered the most common questions from our clients in Neath Port Talbot.

It depends on your project. Pre-fabricated trusses are faster and often more cost-effective for standard new builds. However, a traditional “cut and pitch” roof is superior for bespoke designs, loft conversions, or when working with the irregular walls of older South Wales properties.

These are strength grades. C16 is standard for most domestic work, but we prefer using C24 for our structural joists and trusses. C24 is a higher-grade timber that can handle larger spans and heavier loads, providing a much more robust finish for your roof.

For a standard three-bedroom home, the primary truss installation can often be completed in 1 to 2 days using a crane. Traditional cut roofs take longer—usually 1 to 2 weeks—as every piece of timber is measured and cut on-site.

If you are changing the structure of an existing roof or building a new one, a structural engineer’s calculations are usually required to satisfy Building Control. We can work directly from your engineer’s drawings to ensure everything is built to spec.

Yes. Roof spread happens when the horizontal joists aren’t properly tied to the rafters. We can retro-fit “collar ties” or “purlins” to pull the structure back together and reinforce the timber to prevent any further movement.

Our installation work is fully guaranteed, and the engineered trusses we source come with their own manufacturer warranties. When combined with our preservative treatments, your new roof structure is built to last for 50+ years.
