When Does a Felt Roof Need Replacing?
Minor localised damage does not always mean that the whole roof needs replacing. However, continuing to patch an old roof can become expensive when leaks keep returning.
Roofers working in Galashiels regularly inspect ageing garage, extension and outbuilding roofs. A professional inspection can help establish whether the existing roof still has a reasonable service life.
Common warning signs include:
- A roof surface showing extensive cracking rather than one isolated defect
- Repeated leaks in different parts of the roof
- Numerous old repairs across the felt
- Moisture or air trapped beneath several parts of the felt
- Open or failed seams
- Shrinkage around upstands, kerbs and perimeter details
- An exposed top layer that looks smooth, brittle or badly weathered
- Persistent pools of standing water
- Roof boards that have weakened through water damage
- A heavy build-up of previous coverings and patch materials
- An older system nearing the end of its useful life

The Re-Felting Process in Galashiels
Proper felt roof replacement normally involves stripping the old system and preparing a sound waterproof structure. The precise method will depend on the roof design, existing materials and selected felt system.
Assessing the Existing Felt Roof
The replacement process usually begins with an inspection of the felt and visible roof structure. The assessment may include:
- The age and condition of the felt
- Whether previous coverings have been overlaid
- The likely condition of plywood or OSB beneath the felt
- Roof drainage and standing water
- Wall junctions, kerbs and roof edges
- How materials and waste can be moved safely
- Insulation and condensation risks
Stripping the Old Roof Covering
A full re-felt commonly starts with taking up the worn covering. This allows the contractor to inspect areas hidden beneath the old felt.
The work may include:
- Stripping previous coverings and patch repairs
- Removing unsuitable roofing accessories
- Cleaning old adhesive and debris from the deck
- Keeping exposed areas weatherproof during the work
- Arranging suitable disposal of stripped materials
Roof Deck and Timber Repairs
The roof deck needs to be firm, dry and suitable for the chosen system. The contractor may need to:
- Remove soft and unsuitable decking
- Repair or strengthen damaged joists
- Improve the fall of the roof
- Repair rooflight frames and edge structures
- Correct uneven or sagging sections
- Deal with localised timber deterioration
Adding Insulation During Re-Felting
When the roof covers a heated room, replacement may provide a useful opportunity to improve insulation. Depending on the roof and applicable requirements, the contractor may:
- Create a warm roof build-up
- Renew ineffective thermal materials
- Install a vapour control layer
- Adjust outlets and edges for thicker insulation
- Reduce the risk of condensation beneath the decking
Installing the New Felt System
The new roof will usually consist of several compatible waterproofing layers. This can include:
- Priming the substrate where required
- Installing a base sheet
- Installing an additional waterproof membrane
- Completing the roof with a protective mineral surface
- Using torch-on installation where suitable
- Selecting a flame-free installation method
Completing Perimeter and Junction Work
Careful detailing around edges and walls is essential for a watertight result. Contractors may complete:
- Vertical waterproofing at roof abutments
- Weatherproof coverings at wall junctions
- Drip edges and fascia details
- Waterproofing around skylights
- Weatherproofing around ducts, flues and ventilation pipes
- Parapet and coping details
- Waterproofing around low access points
Finishing Rainwater Outlets
The completed roof should direct water towards suitable gutters or outlets. The contractor may:
- Remove debris from drainage points
- Renew damaged flat roof outlets
- Replace gutters and downpipes where included
- Improve the direction of water flow
- Add secondary drainage to suitable parapet roofs
Final Inspection and Site Clearance
The completed membrane and all junctions should be checked before handover. The contractor may also:
- Leave the working area reasonably clean
- Check gutters and outlets
- Record the completed roof
- Hand over guarantee documentation
- Explain maintenance requirements
Choosing a Felt Roofing System
Multi-Layer Torch-Applied Felt
Torch-on felt is widely used on garages, extensions and larger flat roofs. The layers are heat-welded to create a continuous waterproof covering.
The roof can be completed with a bonded base, waterproof underlay and mineral-finished top layer. Contractors using direct heat should follow appropriate hot-work and fire-safety procedures.
Flame-Free Felt Systems
Some reinforced felt systems use specialist cold adhesives. These options may suit timber structures, sensitive sites and restricted locations.
Peel-and-Stick Membranes
Peel-and-stick roofing felt provides another installation method without torch application. The roof still needs careful surface preparation and correctly sealed laps.
Protective Cap Sheet Finishes
A protective mineral top layer is often installed over the waterproofing underlay. It helps shield the bitumen from sunlight and weathering.
Comparing Felt with EPDM and GRP
Property owners can ask roofers about several possible flat roof coverings. Options may include:
- EPDM rubber roofing
- Glass-reinforced plastic roofs
- Cold-applied liquid roof systems
- Single-ply roofing
- Traditional asphalt flat roofs
A contractor can explain how the available materials compare for your property.

Factors Influencing Replacement Prices
- Roof size: A larger roof requires more felt, insulation and labour.
- Roof shape: Simple rectangular roofs are generally quicker to cover.
- Existing layers: Previous felt and patch repairs can make stripping more involved.
- Decking condition: Rotten boards need to be replaced before re-felting.
- Structural repairs: A sagging roof may require strengthening.
- Insulation: Improving thermal performance can form a substantial part of the quote.
- Felt specification: High-performance systems cost more than basic coverings.
- Access: Difficult sites may require additional equipment.
- Scaffolding: Some roofs need a tower, scaffold or lifting equipment.
- Rooflights and penetrations: Each opening needs careful waterproof detailing.
- Flashing and roof edges: Wall junctions and perimeter details can add cost
- Drainage: Persistent standing water may need more than a simple covering replacement.
- Waste removal: Old felt, timber and insulation need suitable disposal.
- Location: Quotes may differ between central Galashiels and surrounding rural areas.
- VAT: The final total can depend on the contractor's VAT status.
Repair or Replace a Felt Roof?
A contractor should assess the whole roofing system rather than only the visible leak. A repair may still be suitable where:
- The leak has a clear localised cause
- The surrounding felt remains secure and flexible
- There is no widespread timber deterioration
- There is no long history of repeated failure
A complete replacement may be more appropriate where:
- Several areas are cracked or blistered
- Water enters through more than one location
- The mineral surface has deteriorated significantly
- The roof deck is rotten or sagging
- Standing water remains in several areas
- A thermal upgrade is required
- Further repairs would cost a significant proportion of replacement
Expected Lifespan of Replacement Felt
Modern reinforced felt normally lasts longer than basic single-layer roofing felt. A good-quality system may remain serviceable for around 15 to 30 years when properly installed and maintained.
Its lifespan may be affected by:
- The quality of the membrane specification
- The standard of preparation and detailing
- Roof drainage
- The roof's exposure to weather
- Damage caused by maintenance access
- Cleaning and maintenance of outlets
- How quickly small problems are repaired
Understanding Roofing Guarantees
Guarantee periods vary between contractors and roofing systems. Before appointing a roofer, check:
- The period of cover provided for installation
- Whether the complete roofing system is protected
- Who provides the warranty
- What happens if the contractor stops trading
- What could make the guarantee invalid
- Whether the guarantee transfers to a future owner
What to Do Before Re-Felting Starts
Homeowners may need to make a few arrangements before the roofing team arrives. This can include:
- Moving vehicles away from the work area
- Protecting belongings stored beneath the roof
- Discussing practical site requirements with the contractor
- Informing neighbours where access may affect them
- Restricting access to the working area
- Discussing planning or building control matters before work begins
- Understanding weather protection arrangements
How to Compare Re-Felting Contractors
Obtaining several quotes can make it easier to compare the full scope of the replacement. Do not judge quotations only by the final figure.
Check whether each quotation includes:
- Removal of the old felt
- An allowance for rotten roof boards
- The brand or type of roofing products proposed
- Insulation and vapour control work
- Work around walls, rooflights and outlets
- Any separate access charges
- Waste removal and site clearance
- A realistic work programme
- The contractor's VAT status
- Guarantee information
You should also review:
- Evidence of suitable insurance
- Whether the contractor regularly installs the proposed system
- Recent customer references
- How clearly the contractor answers questions
- The amount requested before work begins

Frequently Asked Questions
How long does felt roof replacement take in Galashiels?
Straightforward felt roof replacement commonly takes between one and three days. Larger extension roofs may require several working days. The programme can be extended by rooflights, complicated junctions and insulation upgrades. The contractor should explain the expected start and completion dates before work begins.
Can new felt be installed over the existing roof?
It may be possible to overlay a suitable existing roof, but this is not always recommended. However, covering a damaged roof can hide rotten boards and wet insulation. Ask the contractor to explain why the existing covering is suitable to remain.
What type of felt is best for a replacement roof in Galashiels?
The best specification depends on the building, roof design, budget and required lifespan. High-performance torch-on felt is widely used for durable flat roofs. Basic shed felt is unlikely to provide the same lifespan as reinforced roofing felt.
How long should a replacement felt roof last?
A properly installed professional felt roof may last around 15 to 30 years. Its useful life depends on weather exposure, maintenance and the condition of the structure. Ask the contractor how the selected felt compares with alternative roof coverings.
Will the roofer replace damaged roof boards?
Damaged decking can normally be replaced as part of the project. The full condition may not be visible until the felt is removed, so quotations vary. Ask the contractor to state how additional decking will be charged.
Can insulation be added during the replacement?
Insulation can often be renewed while the old covering is removed. This is especially relevant where the roof covers a kitchen, bedroom or living area. The contractor should explain whether building control may need to be involved.
Does felt roof replacement require planning permission in Galashiels?
Replacing an existing felt covering is generally treated as maintenance. Different rules may apply where the property is listed or within a conservation area. Property owners should confirm the position before making significant external changes.
Will Building Regulations apply to the work?
Building control involvement may be required where the structure or a significant area of covering is altered. Minor repairs may be treated differently. Ask the roofer whether approval is likely to be needed.
Can a felt roof be replaced in winter?
Winter re-felting is possible, although rain, frost and wind may affect the programme. Contractors may rearrange the work around the weather forecast. Confirm how the building will be protected during delays.
How much deposit should I pay?
Deposits are common on larger roofing projects where products need to be ordered. Before paying, make sure the payment schedule is clearly recorded. Avoid paying the full price before work begins.
