What Are Mono Trusses?
Monopitch roof trusses provide a simple, efficient solution for various structures, including garages, sheds and extensions. They're lightweight, quick to install and can be delivered just in time for installation, reducing bulk on site. Thanks to their reduced weight, many mono trusses can be carried and installed by hand on site, negating the need for cranes or other heavy hire equipment.

Class Leading Manufacturing
We have some of the best toys in the industry. We have invested over £2.5M in our brand new facility and have used almost 20 years of manufacturing experience to ensure it does exactly what we want. It’s the secret to turning your project around in as little as 5 days, no matter what the complexity.We run two Hundegger saws from Germany. These saws are truly incredible, allowing us to cut the timber for your project at an astonishing pace whilst achieving pin-point accuracy. The saws are fed directly from our design office and will optimise the use of every length of timber for minimal waste.
Once the timber components are cut, they move directly to one of our truss presses. Our skilled assemblers will set out your truss on the press with the assistance of a laser system—again, fed from our design office. The lasers minimise setup time whilst ensuring perfect accuracy every time. Once the truss is set, a jig is formed for multiple runs. Steel nail plates are then pressed into the timbers using 35 tonne presses to complete the roof truss.
The Timber We Use
All of our trusses and joists are made from TR26 timber. TR26 timber is a high-performance, engineered wood that combines exceptional strength and versatility, making it a top choice for demanding structural applications. It’s specifically graded to ensure consistent quality and reliability, with the ability to withstand heavy loads and offer long-lasting durability. TR26 timber is often used in the construction of roof trusses, floor joists, and other key structural elements, where its strength-to-weight ratio and resistance to wear and decay make it a standout choice. Whether in residential or commercial projects, TR26 provides peace of mind and reliability, ensuring a solid, secure foundation for any build.On top of this, all of our timber is PEFC (Programme for the Endorsement of Forest Certification) certified, meaning when you purchase trusses or joists from us, you're contributing to the health of the woodland that provides our timber. This includes replanting trees when others are felled, ensuring wildlife is cared for and those working in the woodland are paid fairly.
Do Trusses Need to be Treated?
We often get asked whether roof trusses need to be treated, and the simple answer is no, unless you live in the areas marked by the map below.If you live within these areas, you have to live with a helpful little guy called the House Longhorn Beetle. He loves to eat trusses, and for some reason doesn't like to stray from these areas. To prevent your roof falling in on you in the middle of the night, all trusses supplied to these areas have to be treated. If you don't live within these areas, and your trusses are in a dry, well ventilated space, there is no requirement to treat them. If you'd prefer the peace of mind (perhaps you live near these areas), we'll happily treat your timber for you, but just be aware it does add around 10% to the price.
What Are The Benefits of Roof Trusses?
🪽Lightweight: Trusses use up to 40% fewer materials than traditional cut roofs, making them significantly lighter yet just as strong.💷 Cost-effective: Thanks to their rapid installation times and use of fewer materials, they are often cheaper than traditional cut roofs.
💪 Strong: Trusses, with their triangular design, are inherently stronger than traditional methods and will span further without supporting walls.
🏡 Versatile: Roof Trusses are available in a huge variety of configurations to suit your project. These can include attic trusses, raised tie trusses, scissor trusses and more.
⚙️ High quality: Trusses are designed in specialist software and made in a purpose-built factory, ensuring millimetre perfect accuracy every time.
🔨 More site space: Rather than having to store vast amounts of timber on site, trusses can be delivered just in time for installation.

"We wanted to vault the roof of a building from 1850. The existing roof structure was completely rotten. I contacted Tailor Made Designs with the measurements and they quickly turned around a design, 3D-schematic and quotation (these diagrams were better than anything my structural engineer could produce!). The process of tweaking the design, through to ordering and delivery was very easy and fast. Delivery on site was very straight forward and the trusses has been installed by our joiner without any problems. My company works on conversions of old buildings and I wouldn't hesitate to use Tailor Made Designs for our next project. Thank you."
