Pitched roofing provides long-term protection, structural stability, and effective drainage for residential and commercial properties. Whether for a new build, extension, or roof replacement, a properly constructed pitched roof helps prevent leaks, sagging, and weather-related damage while improving the overall lifespan of the building.
At EBT Build, we install pitched roofs across the UK, including trussed rafter roofs, cut roofs, hip roofs, gable roofs, and low-pitch roofing systems. Our service covers roof framing, breathable membranes, battens, roof tiles, slate roofing, lead flashing, and drainage components. All work is completed by our in-house team to current UK building regulations and is often delivered as part of wider roofing services for complete roof system performance.

Every pitched roofing installation is delivered as a managed structural project. We begin by assessing load bearing walls, timber condition, and roof pitch angle before installation starts.
All work aligns with recognised building standards and guidance from the British Standards Institution. Attention is given to correct batten spacing, underlay positioning, and lead flashing installation to prevent water ingress.
In cases where the existing roof structure is severely damaged or outdated, a full roof replacement may be required before installing a new pitched roofing system.
Our pitched roof installation service covers new builds, extensions, and full roof replacements. We install traditional timber frameworks as well as modern trussed systems, ensuring accurate pitch angles and load distribution.
Where required, we also manage pitched roof skylight installation and insulation upgrades to improve natural light and energy efficiency. All roofing materials are fixed securely and sealed correctly to protect the structure beneath. For properties that require traditional roofing materials, slate roofing is another durable option often used for pitched roof construction.
A traditional cut roof is built on site from individual timber rafters, ridge boards, and purlins. We carry out full cut roof installations for new builds, extensions, and replacement roofs where a bespoke timber structure is required.
Trussed rafter systems are prefabricated off site and installed as a complete structural framework. We install trussed rafter roofs on new builds and full roof replacements where speed and structural consistency are the priority.
A hip roof slopes on all four sides and requires precise angular cutting and ridge detailing to install correctly. We carry out full hip roof installations including timber framing, underlay, tile or slate fixing, and hip ridge finishing.
A gable roof has two sloping sides meeting at a central ridge with vertical gable walls at each end. We install gable roofs on new builds and extensions, managing the full structural and weatherproofing scope from framework to final tile.
A mansard roof has two slopes on each side, with the lower slope steeper than the upper. Common on period and Georgian properties, mansard installations require specialist framing and are often carried out as part of loft conversion projects.
Low pitch roofs require careful material selection and detailing to ensure adequate weather resistance at reduced angles. We install low pitch tile and slate systems with correct underlay specification and edge detailing to meet UK building regulations.
A pitched roof installation is not a job where corners can be cut and problems fixed later. Incorrect pitch angles, poor ridge detailing, inadequate ventilation, or weak flashing work will cause structural and weatherproofing failures that are far more expensive to resolve than they were to prevent. At EBT Build we carry out every pitched roof installation with the structural precision the job demands, not the speed that suits a tight schedule.
We have been installing pitched roofs on new builds, extensions, and full roof replacements across the UK for over 10 years. Every project is managed end to end by our own team, priced transparently, and completed to a standard we are confident standing behind long after the job is done.
Over time, individual tiles may crack or slip, and professional tile roof repairs help maintain the durability and weather protection of pitched roofing systems.
Every project begins with a full structural survey. Wall alignment, load bearing capacity, and roof pitch are measured before work starts.
Includes:
Site inspection
Pitch calculation
Structural preparation
Once preparation is complete, timber framing and membrane installation are carried out. Tiles or slates are then fixed securely following correct spacing guidelines.
Includes:
Truss fitting
Membrane placement
Tile or slate fixing
The final stage focuses on ridge sealing, flashing installation, and water flow inspection. Gutters and drainage alignment are confirmed before handover.
Includes:
Ridge fixing
Lead flashing checks
Final inspection and handover
Site visit and scope assessment

A cut roof is built on site from individual timber components, rafters, ridge boards, purlins, and hangers, cut and assembled by an experienced carpenter. It is more flexible in design and better suited to complex roof shapes, loft conversions, and properties where the roof space will be used as a living area. A trussed rafter roof uses prefabricated triangular timber frames manufactured off site and craned into position. Trussed systems are faster to install and more consistent structurally but limit the usable space in the roof. The right system depends on the property type, design requirements, and whether the loft space needs to be accessible. We assesses both options during the survey and recommends the most appropriate system for your project.
The time required depends on the size and complexity of the roof, the system being installed, and weather conditions during the project. A standard trussed rafter roof installation on a new build or extension typically takes three to five days once the walls are at wall plate level. A traditional cut roof on a larger or more complex property can take one to two weeks depending on the design. Full roof replacements involving removal of the existing structure take longer than new installations. EBT Build confirms all timelines in writing after the structural survey so you have a clear schedule before any work begins.
The minimum pitch for a concrete or clay interlocking tile is typically 17.5 degrees, although some manufacturers specify higher minimums depending on the tile profile. Natural slate can generally be installed at pitches from 25 degrees upwards depending on the slate size and fixing method. Installing tiles or slates below the manufacturer’s minimum recommended pitch increases the risk of wind-driven rain penetrating beneath the covering and causing water ingress. EBT Build calculates the correct pitch and specifies the appropriate roofing material during the survey to ensure compliance with both manufacturer guidelines and current UK building regulations.
Planning permission is not required for most pitched roof installations that are like for like replacements or that fall within permitted development rights. However, planning permission may be required if the installation changes the height or appearance of the roof, if the property is listed, or if it sits within a conservation area. New build roofs are covered under the planning permission granted for the overall development. Extensions with pitched roofs may require permitted development approval depending on the size and position. EBT Build checks all relevant planning requirements during the survey phase and advises you on any permissions needed before work begins.
A pitched roof installation involves several layers of materials working together as a complete weatherproof system. The structural framework is built from stress graded timber — either cut on site or fabricated as trusses. A breathable roofing membrane is installed over the framework to provide a secondary waterproof barrier. Treated timber battens are fixed over the membrane to provide a fixing surface for the roof covering. The outer covering is typically clay tiles, concrete tiles, or natural or synthetic slate depending on the design and budget. Lead or code 4 flashing is installed at all junctions, valleys, and penetrations. EBT Build specifies all materials during the survey and includes a full breakdown in the written quote.
Yes, insulation can and should be incorporated into a pitched roof installation where the roof space will be used as a living area or where improved thermal performance is required. For warm roof designs, rigid insulation boards are installed between and beneath the rafters to eliminate cold bridging. For cold roof designs where the loft will remain unused, insulation is laid at joist level on the loft floor with ventilation maintained above. EBT Build discusses insulation requirements during the survey and includes the appropriate specification in the installation plan. All insulation is installed to meet current UK building regulation U-value requirements.
