Professional Slate Roof Repairs
Slate roofs can last for many decades when correctly installed and maintained, but individual slates and surrounding roof details can eventually deteriorate or become damaged.
Common problems include:
Cracked or broken slates
Missing slates
Slipped slates
Loose slates
Damaged slate fixings
Water entering through damaged areas
Deteriorated leadwork
Leaking valleys
Defective ridge or hip details
Storm damage
Recurring leaks following previous repairs
A missing or broken slate may look like a simple problem, but the visible defect is not always the underlying cause.
For example, a leak may involve damaged flashing, failed fixings, deterioration around a roof penetration or an adjacent area of the roof.
That's why we look beyond the individual slate wherever appropriate.
Slate Roof Repair Rather Than Unnecessary Replacement
A common concern for homeowners is being told that an entire roof needs replacing when the actual problem may be localised.
A damaged slate does not automatically mean you need a new roof.
Where the existing roof remains generally sound, repairing the defective area can be a sensible and proportionate solution.
Our approach is to assess:
The condition of the affected slates
The surrounding roof covering
Slate fixing
Battens where accessible
Leadwork and flashing
Valleys and abutments
Ridges and hips
Evidence of water ingress
Any signs of wider deterioration
We then explain what we believe needs attention.
If a local repair is appropriate, we will say so.
If the roof appears to require more extensive work, we will explain why.
Our Slate Roof Repair Services
Individual Slate Replacement
A single cracked, broken or missing slate can allow rainwater into the roof.
We can replace individual slates where appropriate and check the surrounding area for related defects.
This can be particularly useful following storm damage or accidental damage.
Slipped Slate Repairs
Slates can move or slip when fixings fail, the supporting materials deteriorate or surrounding roof details have been compromised.
We investigate why the slate has moved rather than simply putting it back into position.
Broken Slate Replacement
Broken slates should not simply be ignored because a small opening can allow water into the roof structure.
We replace damaged slates where appropriate and inspect the surrounding area for signs of related damage.
Missing Slate Repairs
Missing slates can expose the roof beneath to rain and wind.
If you have noticed a visible gap in your roof covering, contact us rather than waiting for the problem to develop into a larger leak.
Localised Slate Roof Repairs
Not every repair involves one slate.
Where a section of the roof has deteriorated, we can assess the affected area and determine whether a localised repair is practical.
This may involve replacing multiple slates and addressing associated fixings, leadwork, mortar or other roof details.
Fixed-Price Slate Repair From £599
A straightforward option for qualifying slate repairs
We created our fixed-price slate repair service for homeowners who want a clearer route to dealing with an isolated slate-roof problem.
Prices start from £599 for up to 10 slates.
The service is subject to the condition of the roof, accessibility and the work required.
Before booking, we will establish whether the visible problem appears suitable for the fixed-price service.
The agreed scope should clearly explain:
What work is included
What is not included
Access requirements
Any relevant assumptions
Circumstances that could require additional work
This means you have a much clearer understanding of the proposed repair before work begins.

Slate Roof Repairs for Period & Heritage Properties
North West London contains a large number of older properties where the roof is an important part of the building's character.
Traditional slate roofs can include details that differ considerably from modern roofing systems.
Repairs may need to take account of:
Existing slate type
Slate coursing
Traditional roof construction
Leadwork
Chimneys
Valleys
Dormers
Parapets
Ridge details
Abutments
Existing mortar details
We aim to use compatible materials and appropriate repair methods wherever practical, while preserving the character of the existing roof.
What Causes Slate Roof Damage?
Understanding why a slate has failed can help prevent the same problem occurring again.
Age and deterioration
Older slates, fixings and surrounding materials can deteriorate over time.
Storm damage
Strong winds can loosen or dislodge slates, particularly where fixings have already weakened.
Failed fixings
Corroded or deteriorated fixings can allow individual slates to slip.
Impact damage
Slates can be damaged by falling branches, maintenance work and other impacts.
Defective surrounding details
A slate may not be the real source of a leak. Leadwork, valleys, flashing or abutments can sometimes be responsible.
Previous repairs
Poorly executed repairs can sometimes create additional problems or fail to address the original cause.
How We Approach a Slate Roof Repair
1. Tell us what you've noticed
Contact us with your postcode and a brief description of the problem.
If possible, send photographs of the affected area.
2. We assess the likely problem
We consider the visible damage and whether the repair appears suitable for a fixed-price service.
3. We identify the appropriate repair
Where possible, we establish whether the problem is limited to the visible slate or whether surrounding roof details need attention.
4. We explain the proposed work
You receive a clear explanation of the recommended repair and the relevant price basis before work begins.
5. We complete the repair
The work is carried out using methods appropriate to the roof and property.
When Should You Repair a Slate Roof?
You should consider getting a roof inspected if you notice:
A missing slate
Even one missing slate can leave the roof vulnerable to water penetration.
A cracked slate
Cracks can allow water through and may worsen over time.
A slipped slate
A displaced slate can indicate a failed fixing or another underlying issue.
Water entering the loft
Visible water may have travelled from another part of the roof, so finding the actual source is important.
Damp patches or staining
Staining around ceilings, loft spaces or upper walls can indicate a roofing problem.
Repeated leaks
If a roof continues leaking after previous repairs, the original source may not have been correctly identified.
How Much Does Slate Roof Repair Cost?
The cost of slate roof repair depends on the size and nature of the problem.
Factors can include:
Number of slates requiring replacement
Type and availability of slate
Roof height
Access
Scaffolding requirements
Condition of surrounding areas
Leadwork
Valleys
Chimneys
Ridges and hips
Whether additional defects are discovered
Fixed-price slate repairs start from £599 for qualifying work.
Where the repair does not fall within the fixed-price service, we will explain the proposed scope and price basis.

Frequently Asked Questions
Can you replace one broken slate?
Yes. Individual slate replacement is a common localised repair. We will also consider whether there is an underlying reason for the slate failing.
Can you repair a few missing slates?
Yes. Where the surrounding roof remains sound, replacing several missing slates may be a suitable localised repair.
Do you repair Victorian slate roofs?
Yes. We specialise in traditional roofing and our services are particularly suited to period properties.
Do you repair slate roofs after storm damage?
Yes, subject to access and the condition of the roof. Storm damage can involve more than individual slates, so we assess the surrounding area where appropriate.
Do you repair the cause of a leak?
We aim to identify the likely source rather than simply treating the visible symptom. Water can travel through a roof before appearing inside the property.
How quickly can you repair a broken slate?
Priority next-day and same-day appointments may be available depending on your location, the nature of the repair and our schedule.
Do I need a whole new roof?
Not necessarily.
If the roof is generally sound and the problem is localised, repair may be a more appropriate solution than replacement. We will explain what we find.
How much does a slate roof repair cost?
Our fixed-price slate repair service starts from £599 for qualifying repairs. Other work is priced according to the scope and access requirements.
