Slate size, headlap, fixing method and roof pitch must work together to shed rain effectively. Landmark Roofing Solutions installs slate roofs for your property, helping you consider natural slate and fibre-cement options against the building’s requirements rather than treating them as interchangeable products. A slate roof also needs careful setting out. Differences in natural slate thickness, poorly positioned fixings or awkward cuts at valleys can create weaknesses that are easy to miss from ground level. The supporting layers matter just as much: underlay, battens, ventilation and flashings must suit the covering. A considered installation addresses these details before they become slipping slates, moisture problems or repeated leaks around roof features. Landmark Roofing Solutions is a family-run business owned by Robbie Giles, with a four-person team. Customers praise detailed explanations, regular or daily updates, clean and tidy sites, dates given and kept, and competitive quotes. The aim is straightforward: understand what the roof needs, explain the proposed work clearly and discuss the next steps for your roof, rather than asking you to choose a covering without understanding the construction beneath it. Contact Robbie to confirm availability at your property. New slate and tiled roofs carry a 25-year warranty, and the business holds full public liability and employers’ liability insurance. Call Robbie on 07832 878937 to discuss your property.

Why it can’t wait ## Problems the right roof specification should prevent A dependable pitched roof is a complete assembly, not just a neat outer covering. The inspection needs to consider how water drains, how the roof resists wind and how moisture escapes from the roof space. These are the issues to address before agreeing the work. ### Slates slipping because fixings fail Individual slipped slates can reflect local damage, but repeated movement may indicate wider fixing deterioration or batten defects. The pattern matters when deciding between targeted repair and a new slate covering. ### Insufficient headlap for the roof Slate size and overlap need to suit the pitch and exposure. An inadequate headlap can let wind-driven rain pass through the covering even where the slates themselves are undamaged. ### Poor sorting and uneven seating Natural slates vary in thickness and need appropriate sorting and laying. Poor seating can leave slates rocking, vulnerable to breakage or difficult to secure properly. ### Weak cuts at valleys and junctions Narrow or inadequately supported cut slates can become vulnerable points. Valley design, fixing positions and the layout around roof features need consideration before the main courses are laid. ### Assuming every slate remains reusable A slate can look acceptable from below yet show cracks, delamination or weakened fixing holes when examined. Reuse decisions need to consider condition rather than appearance alone. ### Common mistakes we see - Treating natural slate and fibre-cement slate as identical materials with the same handling and fixing requirements. - Selecting a slate size without calculating a suitable gauge and headlap for the roof pitch and exposure. - Reusing damaged slates simply because their colour matches the existing roof. - Focusing on the visible slate while overlooking batten condition, junction details and the suitability of the ventilation design. Our process ## How the job runs, step by step - 01 ### Inspection, understand the roof and access The inspection considers pitch, exposure, slate condition, fixing patterns and the construction beneath, including any recurring movement or leakage around slate roof details. Robbie also considers access for scaffolding, nearby buildings, material handling and any occupied rooms below. Tell him about previous leaks, planned loft alterations and anything already known about the roof structure. These details help establish a practical scope rather than a quote based only on roof area. - 02 ### Diagnosis, agree the specification The specification identifies the appropriate slate type and dimensions, laying gauge, headlap, fixing method and treatment of valleys, ridges and abutments. The proposal should distinguish the planned work from anything that can only be confirmed once coverings are lifted. Ask Robbie how assessment and quoting will be arranged. Material selection, ventilation, junction details and any relevant Building Regulations requirements need to be considered together, so an apparently small omission does not become a separate problem later. - 03 ### Execution, install in a controlled sequence Battens are set out for the selected slate system, natural slates are sorted as required, and courses and cut pieces are fixed with attention to support and correct seating. The sequence needs to allow for safe access, suitable weather and protection of exposed areas. Where concealed defects become visible, their effect on the agreed work should be explained before a change is agreed. Customers value regular updates because they make progress and any necessary decisions easier to follow. - 04 ### Testing/verification, check the complete assembly Checks address slate seating, course alignment, laps, fixing security, vulnerable cuts and the integration of flashings, ridges and ventilation components. Verification is not simply a check that the finished roof looks straight. It includes the routes by which rain leaves the roof and air moves through the specified ventilation arrangement. Any inspection needed for Building Regulations approval should be coordinated at the appropriate stage, not left until everything is concealed. - 05 ### Completion + warranty, understand the finished roof At completion, review the agreed work, the roof junctions and the condition of the working area. Discuss sensible maintenance, including keeping rainwater outlets clear and arranging checks after significant storm damage. New slate and tiled roofs carry a 25-year warranty. Ask Robbie to explain the applicable warranty terms and documentation, and keep those details with the agreed scope and any relevant approval records. What you get ## The benefits of doing it properly ### Speed through better preparation An agreed covering, access plan and sequence reduce avoidable decisions once the roof is open. That helps work progress efficiently without promising a fixed turnaround before the roof size, complexity, weather exposure and condition are understood. ### Safety planned into the work Scaffolding, edge protection and controlled material handling are part of planning roof work, not optional extras to improvise later. Discussing access early also helps protect entrances and occupied areas while work takes place above them. ### Longevity beyond the visible covering Suitable battens, underlay, fixings and ventilation support the life of the whole roof. Correctly detailed valleys, eaves and flashings help prevent local weaknesses from undermining an otherwise durable slate or tiled covering. ### Cost savings from the right scope Comparing complete specifications helps avoid paying for an attractive covering while leaving failing junctions underneath. Where sound components can reasonably remain, inspection should identify them; unnecessary replacement is not the same as a thorough roofing job. ### Reliability at vulnerable junctions Chimneys, rooflights, abutments and changes in roof slope need deliberate detailing. Getting these interfaces right reduces the risk of recurring leaks that are difficult to trace because water can travel before becoming visible indoors. ### Peace of mind with clear information Clear scope, understandable updates and a 25-year warranty on new slate and tiled roofs give you a clearer basis for decisions. Landmark Roofing Solutions also holds full public liability and employers’ liability insurance. In detail ## What matters when specifying slate roofing The best-looking option is not automatically the right technical choice. Roof pitch, exposure, structural capacity and the way the building is used all influence the specification. Understanding these details makes it easier to compare proposals on substance rather than appearance alone. ### Natural slate and fibre-cement slate Natural slate is split from stone and has variation in texture, thickness and colour. That variation contributes to its appearance but also affects selection and laying. Suitable slates need to be sound, appropriately graded and compatible with the roof design. Natural slate should not be chosen on colour alone: dimensions, thickness, exposure and the required overlap all influence the specification. Fibre-cement slate is a manufactured product with more consistent dimensions and appearance. It has its own fixing, cutting and installation requirements, which should be followed rather than borrowed from natural slate practice. It can offer a different balance of appearance, weight and cost, but suitability remains product-specific. Compare the complete installed system, including fittings and detailing, rather than judging either option by the covering sample alone. ### Underlay, battens and ventilation work together Slates and tiles shed most rainfall, while the underlay provides a secondary line of protection beneath them. Underlay laps, support and drainage at the eaves must suit the roof design. Battens provide the fixing positions for the covering, so their grade, spacing and support matter. A covering installed over unsuitable battens or poorly arranged underlay can conceal problems rather than solve them. A breathable membrane does not automatically remove the need for ventilation. The arrangement depends on the roof construction, insulation position, membrane specification and moisture conditions inside the building. Cold roof spaces and insulated roof slopes need different consideration. Blocking the eaves with insulation, or adding ridge ventilation without a suitable overall strategy, can leave moisture trapped where it causes condensation and timber deterioration. ### Setting out, fixings and slate roof details Slates are commonly laid in a double-lap arrangement, with the gauge and headlap determining how successive courses protect the roof. Accurate setting out helps avoid awkward narrow pieces at edges and roof features. Natural slates may need sorting by thickness so they sit properly in the covering. Fixings should hold each slate securely without creating stresses that encourage cracking or prevent correct seating. Ridges, hips, valleys and abutments need details compatible with the slate covering and the roof geometry. Where a dry ridge system is proposed, it must suit the assembly and any ventilation requirement. Around chimneys, appropriately formed flashings and soakers help direct water away from the junction. Neat slate courses cannot compensate for an unsuitable flashing detail or a valley that restricts water flow. ### Junctions, rainwater and approvals Water concentrates at valleys and changes direction around chimneys, rooflights and adjoining walls. These locations need compatible flashings, adequate overlaps and unobstructed drainage. Lead flashing must accommodate movement and be detailed for its location; simply adding sealant over a failed junction is not equivalent to rebuilding it correctly. Eaves details must direct water into the gutter rather than behind the fascia or onto vulnerable timber. Building Regulations approval is normally required for substantial re-roofing, and thermal upgrades may need consideration where applicable. Planning permission is a separate question: listed buildings, conservation areas and some alterations can have additional restrictions. Establish the relevant route before work starts. Structural changes or a materially different covering load may also require professional assessment rather than an assumption that the existing roof can accommodate them. ### Occupied homes and commercial premises On an occupied home, roof work needs to account for people moving through entrances, items stored in the loft and rooms directly beneath the work. Dust and disturbance cannot always be eliminated, but discussing likely effects helps you prepare. Extensions, porches and adjoining roofs also need attention because the main roof must connect to them without creating awkward drainage or maintenance problems. Commercial premises may have different access constraints, shared boundaries or activities that cannot simply stop during roofing work. The appropriate sequence depends on the building, not just the covering selected. Explain opening hours, sensitive internal areas and any restrictions on scaffolding or deliveries before the scope is agreed. A realistic plan should also account for weather interruptions rather than treating the proposed programme as an unconditional completion guarantee. ### Related services - Slate Roof Repairs - Complete Re-Roofs - New Pitched Roofs - Tiled Roofing ### Need it looked at? 07832 878937Phone answered 24/7. FAQs ## Slate Roofing: your questions answered ### How much does slate roofing work cost? The price depends on roof size, condition and materials. Access, roof shape, insulation requirements and the condition of junctions can also affect the scope. Ask Robbie about quote arrangements and what the proposed work would cover. When comparing quotes, check whether scaffolding, battens, underlay, ventilation, flashings and disposal are included rather than comparing only the headline description. ### How long will the work take? The timeline depends on the roof area, complexity, access, weather and any concealed defects found during the work. A simple roof and a roof with several valleys, chimneys and rooflights need different programmes. Discuss the likely sequence and dates with Robbie after inspection. Customers praise dates given and kept, but weather-sensitive roofing still needs sensible allowance for conditions that make work unsafe or unsuitable. ### What happens before installation starts? Contact Robbie to discuss what you need from the roof and ask how assessment and quoting will be arranged. Before work begins, clarify the chosen material, access arrangements, ventilation approach, treatment of junctions and any approval requirements. It is also worth agreeing how unexpected findings will be explained, especially where existing coverings hide the condition of timber or other components. ### What warranty comes with the roof? Landmark Roofing Solutions provides a 25-year warranty on new slate and tiled roofs. Ask Robbie to explain the applicable terms and the documentation for your installation. This is different from the five-year warranty available on qualifying repairs, where terms depend on the extent of the repair. Keep the warranty information alongside the agreed specification so the work covered is clear. ### How long should the roof covering last? Sound natural slate can remain serviceable for many decades and may outlast the fixings or other roof components. Fibre-cement slate has a different service profile that depends on the product and conditions. Neither option has one universal lifespan. Slate quality, exposure, installation and maintenance all matter, and a durable covering still needs periodic attention to flashings, gutters and any storm damage. ### Can I call if the existing roof starts leaking urgently? Yes. Call 07832 878937: the phone is always answered 24/7, and emergency assistance is available. Explain whether water is near electrical fittings, whether any materials have fallen and which areas are affected. Stay off the roof and keep clear of unstable materials. Emergency availability does not mean a full replacement can be undertaken immediately; safe access, weather and the necessary scope still need assessment. ### Which local areas do you cover? Call Robbie on 07832 878937 with your town or postcode to confirm availability at your property. The town list on this website is for enquiries, not confirmed coverage. ### Will the work need Building Regulations approval? Substantial re-roofing normally requires Building Regulations approval, and relevant thermal performance requirements may apply. A new roof forming part of an extension or new building must also fit the wider approved construction. Planning requirements are separate, particularly for listed buildings or properties with local restrictions. Confirm the approval arrangements before starting rather than assuming that using a similar-looking covering removes every requirement. ### Should insulation and ventilation be considered together? Yes. Adding insulation changes how heat and moisture move through the roof. The position of insulation, continuity of any vapour control layer and ventilation provision all need to suit the construction. A breathable underlay alone is not a universal solution. Discuss existing condensation, bathroom extraction and plans to use the loft, because a storage loft and an occupied roof space can require different approaches. ### Can the house stay occupied during the work? That depends on the scope, the building’s condition and how safe access and protection can be maintained. Many roofing projects can be planned around occupation, but this should not be assumed where structural defects or extensive internal work are involved. Tell Robbie about children, pets, shared entrances and any rooms that cannot be used. Discuss expected disruption and protection before agreeing the programme.
