Slate Roofing in Exeter
Bramwell Roofing Devon provides professional slate roofing services throughout Exeter for homeowners, landlords, property managers and businesses.
Natural slate remains a familiar roofing material on many of the city’s older properties, particularly traditional terraces, period homes and buildings that have retained more historic roofing materials.
Slate can provide long-term protection when the roof is properly maintained, but individual slates, fixings, flashing and adjoining roofing components can still deteriorate over time.
A small number of slipped or damaged slates does not automatically mean the entire roof needs replacing.
In many cases, localised repairs can restore protection where the surrounding roof remains in good condition.
Call 01392 308173 or 07598 001 200 if you have noticed a problem with a slate roof in Exeter.
Common Slate Roof Problems
Slate roofs can develop a number of different defects as they age.
These may include:
- Slipped slates
- Cracked or broken slates
- Missing slates
- Deteriorated fixings
- Weather-related damage
- Flashing defects
- Valley problems
- Leaks around chimneys
- General ageing and deterioration
The correct repair depends on understanding whether the problem affects only one section or reflects wider deterioration across the roof.
Why Do Roof Slates Slip?
A slate can move for several reasons.
The slate itself may have cracked, or the fixing securing it may have deteriorated.
Movement can also occur following severe weather, particularly where materials were already beginning to weaken.
When one slate has slipped, it is sensible to consider the surrounding area rather than assuming the visible defect is the only issue.
The condition of neighbouring slates and relevant roof junctions may also help explain why the problem has developed.
Cracked and Broken Slates
Individual slates can crack through ageing, impact or movement.
A cracked slate may still appear to be in position while allowing rainwater to reach the layers beneath.
Where the surrounding roof remains serviceable, damaged slates can often be replaced individually.
This is one of the main reasons why a slate roof should not be condemned simply because a small number of defects have appeared.
Slate Roof Leaks in Exeter
A leak on a slate roof may result from a displaced or broken slate, but that is not the only possible cause.
Water can also enter around:
- Chimney flashing
- Valleys
- Roof junctions
- Ridge areas
- Adjoining walls
- Rooflights
- Other penetrations
The visible damp inside the property may not sit directly beneath the external defect.
Water can travel beneath the covering before becoming visible indoors.

Slate Roofing on Older Exeter Properties
Exeter contains a substantial number of older buildings where slate forms part of the original or long-established character of the property.
These roofs may have undergone several generations of repair.
Different fixing methods, previous patching, chimney work, rooflights and extensions may all influence the way the roof performs today.
Older does not automatically mean unsuitable.
Where substantial areas remain sound, repairing defective sections can often be more appropriate than replacing the entire covering.
The existing materials and construction should be understood before major work is recommended.
Slate Roofing on Period Terraces
Traditional terraces can present particular roofing considerations because individual properties may share rooflines or adjoin neighbouring buildings closely.
A leak may relate to one section of slate, but adjoining chimneys, party-wall junctions, valleys or flashing should also be considered where relevant.
Repairs should therefore be based on the exact position and cause of the defect rather than treating every problem as identical.
Chimneys and Slate Roofs
Chimney stacks are common on older slate-roofed properties.
They create additional roof junctions that rely on effective flashing and sound surrounding materials.
If water appears near a chimney breast, the source may involve:
- The flashing
- Mortar joints
- Brickwork
- Adjacent slates
- Another nearby junction
The chimney and slate covering should therefore be assessed together.
Our chimney repair and replacement service provides further information.
Valleys and Roof Junctions
Valleys are designed to channel water between adjoining roof slopes.
Because they carry significant quantities of rainwater, defects in these areas can lead to leaks even where the visible slate covering remains largely intact.
The same applies to other junctions where the roof meets walls, dormers or extensions.
These areas should be considered when diagnosing recurring water ingress.
Storm Damage to Slate Roofs
Strong winds can expose weaknesses in older slate roofs.
Slates that have already become loose through deteriorating fixings may be more susceptible to displacement.
Following severe weather, property owners may notice:
- Slates on the ground
- Gaps in the roof covering
- New internal damp
- Changes around ridge areas
- Damaged guttering
Any visible change is worth investigating before repeated rainfall reaches the layers beneath.
Property owners should never climb onto a roof themselves to inspect suspected storm damage.
Can Individual Slates Be Replaced?
Often, yes.
Where one or a small number of slates have failed and the surrounding roof remains in suitable condition, individual replacement may be enough.
The objective should be to preserve sound roofing materials wherever practical rather than replacing more of the roof than necessary.
The surrounding area should still be checked to make sure the defect is not part of a wider pattern.
When Does a Slate Roof Need More Extensive Work?
More substantial intervention may be required where defects are no longer limited to isolated slates.
Signs that the wider roof may need attention include:
- Repeated slippage across several areas
- Widespread cracking
- Multiple leaks
- Increasingly frequent repairs
- General deterioration of fixings
- Problems affecting large sections of the covering
In these situations, the condition of the complete roof should be considered.
Slate Roof Replacement in Exeter
Replacement becomes more relevant where extensive deterioration means localised repair is no longer practical.
The existing property, roof pitch, construction and character should all be taken into account when planning replacement work.
This is particularly important on older buildings where the roof contributes significantly to the appearance of the property.

Repair or Replacement?
A slate roof should not be replaced simply because it is old.
Repair is usually the more proportionate approach where:
- The defect is localised
- Most slates remain serviceable
- Fixing problems are confined to a limited area
- Leaks can be traced to specific defects
- Previous repairs have not become widespread
Replacement becomes more relevant where:
- Slippage is occurring throughout the roof
- Many slates are cracked or damaged
- Fixings have deteriorated extensively
- Leaks continue to appear in several locations
- Ongoing repair is becoming impractical
The decision should be based on the actual condition of the roof rather than age alone.
Slate Roofing and Conservation Considerations
Some Exeter properties are located in areas where the external appearance of the building may have particular heritage or planning importance.
Where major roofing alterations are being considered on a character property, owners should check whether any relevant planning or conservation requirements apply.
Localised maintenance and repair can often help retain existing materials for longer, but significant replacement work should be planned with the individual building in mind.
Slate Roof Maintenance
Slate roofs do not require unnecessary intervention when they are performing well.
However, visible changes should not be ignored.
From ground level, property owners can look for:
- Slipped or missing slates
- Slate fragments on the ground
- New damp marks indoors
- Deterioration around chimneys
- Gutter blockages
- Changes following storms
Early investigation can help keep repairs more contained.
Guttering and Slate Roofs
Blocked or damaged guttering can create water-related problems that may initially appear to originate from the roof covering.
Leaves, moss and debris can restrict water flow, while cracked joints may allow water to overflow close to external walls.
Our gutter repairs and cleaning service can be considered where drainage issues are contributing to the problem.
Slate Roofing for Landlords
Older rental properties may contain traditional slate roofs that have undergone previous repairs.
Promptly investigating leaks can help limit disruption to tenants and prevent water from affecting ceilings, decoration and insulation.
Where the roof has required several repairs over time, a broader condition assessment may also be useful.
Slate Roofing for Commercial and Mixed-Use Buildings
Some older commercial and mixed-use buildings also retain slate pitched roofs.
These properties may include more complex roof junctions, chimneys or adjoining sections.
The use of the building and the need to minimise disruption can influence how repair work is planned.
What Happens During a Slate Roof Assessment?
The assessment begins with the problem you have noticed.
This may be a slipped slate, active leak, visible gap or general concern about the condition of an older roof.
The relevant areas can then be considered, including:
- Individual slates
- Fixings
- Flashing
- Valleys
- Chimneys
- Ridges
- Adjoining roof junctions
- Guttering
The aim is to establish whether a localised repair is suitable or whether the wider roof condition requires attention.

Frequently Asked Questions
Can individual slipped slates be repaired?
Often, yes. Where the surrounding roof remains serviceable, individual defective slates may be replaced without disturbing the whole covering.
Does one broken slate mean I need a new roof?
No. A single localised defect would not normally justify replacing an otherwise serviceable slate roof.
Why do slates start slipping?
Possible causes include deteriorated fixings, cracking, movement and weather exposure.
Can you replace a complete slate roof in Exeter?
Yes. Replacement can be considered where deterioration is sufficiently widespread that localised repairs are no longer practical.
Can a slate roof leak even if no slate is missing?
Yes. Flashing, valleys, chimney junctions and other roof details can also allow water to enter.
