When Your Roof Needs More Than a Repair
Every roof has a lifespan. Concrete tiles typically last 40–60 years, clay tiles 60–100 years, and slate can exceed a century. But when tiles are crumbling, felt has deteriorated, or timbers are showing signs of rot, continuing to patch and repair becomes a false economy. A full roof replacement is often the most cost-effective solution.
At Topnotch Roofing & Property Maintenance Ltd, we manage the entire replacement process. We strip the existing roof down to the rafters, inspect and replace any damaged timbers, install modern breathable membrane, new battens, and your chosen tile or slate system. The result is a roof that performs like new — properly ventilated, fully insulated, and built to modern building standards.
We work with homeowners across Swindon, Cheltenham, Gloucester, Cirencester, and the wider Gloucestershire area. Every replacement project is tailored to your property's specific requirements, and we handle all aspects including scaffolding, skip hire, and waste disposal.
A new roof doesn't just stop leaks — it transforms your property. It improves energy efficiency, eliminates damp risks, increases kerb appeal, and adds measurable value to your home. Most of our roof replacements are completed within 3–5 working days, and every project comes with both a workmanship guarantee and manufacturer material warranties.
Our Roof Replacement Work
Signs Your Roof Is Beyond Repair
Multiple Active Leaks
If you're dealing with leaks in several locations, the underlying felt and structure are likely compromised. Patching individual spots won't solve a systemic problem.
Sagging Ridgeline
A visible dip in your roofline indicates structural timber damage. This requires immediate professional assessment — the issue will only worsen over time.
Widespread Tile Deterioration
When tiles are crumbling, delaminating, or cracking across large areas, the material has reached the end of its useful life. Replacing individual tiles becomes an endless cycle.
Failed Roofing Felt
If the felt beneath your tiles has torn, sagged, or disintegrated, water passes straight through to the timber structure. A re-felt requires a full strip and retile.
Persistent Damp Despite Repairs
When damp keeps returning after multiple repairs, the problem is usually deeper than surface-level tile damage. A full replacement addresses every layer of the roofing system.
Roof Age Over 50 Years
Roofs over 50 years old with original tiles and felt are operating beyond their design life. Proactive replacement prevents emergency situations and allows you to plan the cost.
How We Replace Your Roof — Step by Step
Comprehensive Roof Survey
We inspect your existing roof in detail — tiles, felt, timbers, ventilation, and insulation. We identify every issue and explain what needs addressing.
Specification & Quote
You receive a full specification covering materials, colours, ventilation requirements, and a fixed-price quote. We walk you through every detail so you can make an informed decision.
Scaffolding & Setup
We erect scaffolding, lay protective sheeting, and set up waste disposal. Your property is fully protected before any work begins.
Strip & Timber Inspection
The old roof is carefully stripped down to the rafters. We inspect every timber, replacing any that show signs of rot, woodworm, or structural weakness.
Membrane, Battens & Tiles
We install breathable roofing membrane, pressure-treated battens, and your chosen tiles or slate. Flashings, valleys, and ridges are fitted with precision.
Final Inspection & Handover
We conduct a thorough quality check, photograph the completed work, and walk you through the finished result. All guarantees and warranties are documented and handed over.
What a New Roof Delivers for Your Property
Decades of Protection
A new roof installed with quality materials and expert workmanship protects your property for 40–100 years depending on the tile system chosen.
Lower Energy Bills
Modern breathable membranes and improved insulation reduce heat loss through your roof, cutting heating costs measurably from the first winter.
Zero Leaks, Zero Damp
Every layer of your new roof is designed to prevent water ingress. No more buckets, no more stained ceilings, no more mould concerns.
Increased Property Value
A new roof is one of the strongest signals of a well-maintained property. Buyers pay more for homes with recent roof replacements — often recovering the full cost.
Warranty Protection
Premium materials carry manufacturer warranties of 20–30 years. Combined with our workmanship guarantee, your investment is fully protected.
Building Regulation Compliance
Our installations meet or exceed current building regulations for ventilation, insulation, and structural integrity — essential for future property transactions.
Everything You Need to Know About Roof Replacements
Choosing the Right Tile System
The three main tile options are concrete, clay, and natural slate. Concrete tiles are the most affordable and come in a wide range of profiles and colours — ideal for budget-conscious projects where performance matters more than aesthetics. Clay tiles offer superior weather resistance and a distinctive traditional appearance. They cost more than concrete but last significantly longer. Natural slate is the premium option — lightweight, incredibly durable, and unmatched in visual quality. Welsh slate can last 150+ years. We'll help you choose the best option based on your property style, local planning requirements, and budget.
Timber Inspection & Replacement
Stripping a roof provides the only opportunity to properly inspect the timber structure. We check every rafter, purlin, and ceiling joist for signs of rot, woodworm, and structural movement. Any compromised timbers are replaced with treated structural-grade timber that meets current building standards. This is a critical step — installing new tiles on weakened timbers would be like building a house on sand.
Breathable Membrane vs Traditional Felt
Modern roof replacements use breathable roofing membrane (BRM) rather than traditional bituminous felt. BRM allows moisture vapour from inside the property to escape through the membrane while preventing rain and wind from entering. This dramatically reduces the risk of condensation in the roof space, which is a major cause of timber rot in older properties. BRM is now a building regulation requirement for most installations.
Ventilation Requirements
Building regulations specify minimum ventilation levels for roof spaces to prevent condensation and ensure insulation performs correctly. The required ventilation depends on your roof pitch, insulation type, and whether the loft is cold or warm. We calculate the exact requirement for your property and install the appropriate combination of soffit vents, tile vents, and ridge vents. Proper ventilation is non-negotiable — it protects every other component in your roofing system.
Dry Ridge vs Mortar Bedded Ridge
Traditional ridge tiles are bedded in mortar, which eventually cracks and fails. Dry ridge systems use mechanical fixings — clips and brackets — to secure ridge tiles without mortar. They're maintenance-free, allow thermal movement without cracking, and provide better ventilation. Dry ridge is now the standard for new installations and is the system we recommend for every roof replacement.
Planning Permission & Building Control
Most like-for-like roof replacements don't require planning permission. However, changing the roof profile, height, or material in a conservation area or on a listed building may require approval. We advise on any planning considerations before work begins. Building control notification may be required depending on the scope of work — particularly where structural changes or significant insulation upgrades are involved. We handle all necessary compliance.
