At Crown Guard Roofing Services, we are specialist slate roofers working across Watchfield, Swindon, Oxford, Witney, Carterton, Abingdon, Didcot and the surrounding areas. As a family-owned business with over 10 years of hands-on experience, we’ve worked on slate roofs of every age and style — from new high-end builds to careful restoration of period properties, listed buildings and traditional Cotswold homes.
A slate roof is in a class of its own. Few roofing materials match the timeless beauty, character and durability of natural slate — which is why it’s been the premium choice for British homes for centuries. A properly installed slate roof can last 80–100+ years, develops a beautiful patina with age, and adds genuine, lasting value to any property.
But slate roofing is also one of the most demanding crafts in the trade. Each slate must be hand-graded, properly fixed, and laid with precise attention to head laps, side laps and weather detailing. Get it wrong, and even the most expensive slates will fail within years. Get it right, and your roof will outlast you.
That’s where our experience matters. Whether you need a brand-new slate roof, careful repairs to existing slates, or full restoration of a heritage property, we deliver work that’s done properly, looks stunning, and lasts. Every slate roof is fully insured and backed by our 15-year workmanship guarantee for total peace of mind.
We work with every type of slate from premium natural Welsh slate to budget-friendly synthetic alternatives. We’ll help you choose the right slate for your property’s style, your budget, and how long you want the roof to last.
Welsh Slate The gold standard of British roofing slate for nearly 200 years. Welsh slate is renowned worldwide for its dense, even texture, deep blue-grey colour, and exceptional longevity. The premium choice for character properties and high-end new builds.
Best for: Period properties, listed buildings, premium new builds, and any property where authenticity and longevity matter most.
Key benefits:
Spanish Slate Spanish slate offers excellent quality at a more accessible price point than Welsh slate. Top-grade Spanish slate is widely used across the UK and provides outstanding performance and a beautiful natural finish.
Best for: New builds, re-roofs and properties wanting natural slate without Welsh slate prices.
Key benefits:
Reclaimed Natural Slate Beautiful, characterful slates carefully reclaimed from historic roofs and given a second life. Ideal for restoring period properties where matching the original look is essential.
Best for: Listed buildings, conservation areas, period restorations, and homes in Cotswold or heritage settings.
Key benefits:
Slate roofs can last a century but they don’t always need replacing when they start showing problems. Knowing the warning signs helps you act early and often saves the original slates. Here’s what to look out for:
If your slate roof is 50+ years old and you’re seeing multiple slipped slates at once, it’s often a sign of “nail sickness” — where the original iron nails have rusted through. In this case, the slates may still be sound but the fixings have failed. We can usually salvage and re-lay the original slates onto fresh battens and underlay.
A slate roof from Crown Guard Roofing is more than just protection — it’s a long-term investment that pays you back for decades. Here’s what you gain:

Slate roofing is a specialist trade. Many general roofers can fit concrete tiles competently, but slate demands genuine craft skills — proper hand-grading, accurate head laps, careful fixing, and the experience to know when a roof can be saved versus when it needs replacing. As a family-owned roofing company with over a decade of hands-on slate experience, we bring that craft to every project.
Our customers often ask the same questions about slate roofing, so here are clear, honest answers to the most common ones:
That depends on the slate type:
A well-installed natural slate roof from a reputable installer will easily reach the upper end of those ranges. Our 15-year workmanship guarantee covers the installation work itself.
Welsh slate is the premium choice — exceptional quality, longest lifespan, but the most expensive.
Spanish slate offers excellent quality at a more accessible price — the most popular choice for new slate roofs.
Reclaimed slate is essential for heritage properties and conservation areas where matching the original is required.
We'll always recommend the right slate for your specific property and budget.
For most domestic properties, a typical slate re-roof takes between 5 and 10 days depending on the size of the property, the type of slate, and the weather. Slate is more time-consuming to lay than concrete tile because each slate is fixed individually.
Slate roofing is generally a premium investment — it costs more than concrete tile but lasts considerably longer. Costs depend on the size of your roof, the slate chosen, scaffolding, and the condition of the existing structure. We provide free, fixed-price written quotes so you'll know the exact price before any work begins.
Not necessarily. Many slate roof problems come from "nail sickness" — where the original iron nails have rusted through, but the slates themselves are still perfectly sound. In these cases, we can often strip the roof, replace the underlay, battens and fixings, then re-lay the original slates at a fraction of the cost of new materials. A free inspection will tell you exactly what's possible.
Yes, very often — particularly with Welsh slate, which can have decades of remaining service life even on roofs over 100 years old. We carefully strip, hand-grade and re-lay sound slates onto fresh underlay and battens. This is the best of both worlds: original character, modern weatherproofing.
Yes. We carry out sympathetic slate roofing work on listed buildings, period homes and properties in conservation areas across Oxford and the Cotswolds. We work with reclaimed materials, traditional fixing methods, and the right detailing to satisfy planning and conservation requirements.
