Re-Felting Specialists Across Oxfordshire

Many property owners across Oxfordshire eventually need to replace an ageing or damaged felt roof. Garages, extensions, porches, dormers and outbuildings throughout the county commonly rely on felt roofing. Over time, weathering can weaken the membrane, joints and perimeter details.

When Re-Felting Is Better Than Another Repair

A small split or isolated leak can sometimes be repaired without replacing the whole roof. However, a complete re-felt is often more practical when several areas have started to fail.

Many replacement enquiries in Oxfordshire involve older garage and extension roofs that have already received several temporary repairs. A professional inspection can help establish whether the roof can still be repaired or should be replaced.

Signs that a felt roof may need replacing include:

• Widespread cracks in the roof covering
• Water ingress returning after previous repairs
• Blisters, bubbles or raised sections across the surface
• Failed joints between felt sheets
• Exposed gaps around roof edges, kerbs or wall junctions
• Large areas of worn or missing mineral finish
• Large pools of water remaining after rainfall
• Decking that feels weak, uneven or water-damaged
• Several layers of old felt already covering the roof
• A roof covering that is close to the end of its useful life

How Contractors Re-Felt a Roof

A professional replacement involves more than laying new felt over the existing surface. The exact method will depend on the type of building and the condition of the roof.

Assessing the Roof Before Replacement

The contractor will inspect the roof covering, drainage and visible structural condition. The survey may consider:

• How badly the existing covering has deteriorated
• How much old felt needs to be stripped
• The condition of the roof decking
• Whether rainwater reaches the outlets correctly
• How the felt is finished around edges and adjoining walls
• Access, height and safety requirements
• Whether the roof requires a warm roof upgrade

Preparing the Roof for Re-Felting

The old felt is normally removed to expose the roof deck. This allows the contractor to inspect areas that could not be seen before stripping.

The work may include:

• Taking up the existing bitumen covering
• Removing damaged edge trims and flashings
• Preparing the deck for the new system
• Keeping exposed areas weatherproof during the replacement
• Loading and disposing of old roofing waste

Replacing Damaged Roof Boards

Any weak or water-damaged boards should be dealt with before the roof is re-felted. Contractors may need to:

• Replace rotten plywood or OSB boards
• Address weak supporting timbers
• Adjust the supporting timbers to direct water towards the outlets
• Replace damaged timber kerbs
• Level unsuitable sections of decking
• Allow damaged areas to dry before the new roof is installed

Insulation and Warm Roof Upgrades

Re-felting a roof above living space can involve upgrading its thermal performance. Depending on the building and applicable requirements, the work may include:

• Adding new insulation boards beneath the felt covering
• Replacing wet or compressed insulation
• Adding a layer to help manage internal moisture
• Changing perimeter details to accommodate the upgraded roof system
• Improving ventilation where a cold roof design remains

Laying the Replacement Felt

A contractor may install a reinforced multi-layer bitumen roofing system. Depending on the chosen specification, this can include:

• A preparation coat or primer
• Installation of a suitable base sheet
• Installation of a high-performance underlay
• A mineral-finished cap sheet
• Heat-welded installation by an experienced roofer
• Adhesive systems where direct heat is unsuitable

Roof Edges, Upstands and Flashing

Many flat roof leaks begin around edges, walls and penetrations. The contractor may complete:

• Waterproofing where the flat roof meets brickwork or render
• Replacement lead or alternative flashing
• Perimeter trims directing water away from the building
• Felt and flashing work around raised roof perimeters
• Rooflight and lantern kerbs
• Sealing around services passing through the roof
• Waterproof detailing around roof-level doors

Gutters, Outlets and Flat Roof Drainage

A replacement roof needs correctly positioned and functioning outlets. The contractor may:

• Check that outlets are open and usable
• Repair or replace damaged outlets
• Renew damaged rainwater goods
• Adjust roof falls to reduce persistent pooling
• Install overflow provisions where required

Completing the Felt Roof Replacement

A final inspection should confirm that joints, edges and outlets have been completed correctly. The contractor may also:

• Clear roofing waste and unused materials
• Confirm that rainwater can leave the roof
• Supply before-and-after images where agreed
• Issue an invoice and written guarantee
• Advise how the roof should be inspected

Types of Felt Roof Replacement

Torch-On Felt Roofing

Many professional felt roof replacements use reinforced torch-on membranes. The layers are installed using controlled heat by a suitably experienced roofer.

A typical installation may include a base layer, reinforced underlay and mineral-finished cap sheet. Torch-on work should be carried out by a contractor familiar with hot-work safety.

Adhesive Roofing Membranes

Cold-applied systems use specialist adhesives rather than direct heat. These systems may be suitable for buildings where direct heat would present an additional risk.

Self-Bonding Felt Systems

Self-adhesive membranes have a prepared backing that bonds to a suitable substrate. Proper surface preparation remains important, and the roof deck must be clean, dry and compatible with the product.

Replacement Felt with a Mineral Finish

The top layer of many felt systems has a coloured mineral finish. This surface helps shield the roof from ultraviolet exposure.

Other Materials for Flat Roof Replacement

Some contractors in Oxfordshire also install alternative flat roofing materials. Alternatives may include:

• Single-sheet EPDM membranes
• Rigid fibreglass roofing systems
• Liquid-applied waterproofing
• Commercial single-ply roofing
• Seamless mastic asphalt systems

The most suitable option depends on the roof shape, expected lifespan, access and budget.

How Much Does Re-Felting Cost in Oxfordshire?

Every replacement project is different, so contractors usually need to inspect the roof before confirming a price. The final quotation may be affected by the amount of decking replacement, insulation work and scaffolding required.

The table provides general budgeting guidance rather than guaranteed prices. For accurate local pricing, use our service to hear from suitable local specialists.

What Affects Felt Roof Replacement Prices?

• Roof area: The total square metre area is one of the main cost factors.
• Roof shape: Complex roofs require more cutting, joining and detailing.
• Existing roof layers: Removing several old felt layers increases labour and disposal costs.
• Decking condition: Hidden water damage can increase the final cost.
• Structural timber: Sagging or damaged structures can increase the project scope.
• Insulation: Adding a warm roof system can raise the initial price.
• Felt specification: The number and grade of roofing layers affect the price.
• Access: Properties without straightforward roof access may cost more to work on.
• Scaffolding: Higher roofs may need scaffolding or edge protection.
• Rooflights and penetrations: Complex roof features increase installation time.
• Flashing and edges: Failed flashing and kerbs can add additional work.
• Drainage: Correcting falls or replacing outlets may increase costs.
• Waste removal: Skip hire or licensed collection may be included.
• Location: Parking, travelling distance and local rates can affect quotations.
• VAT: A VAT-registered contractor should confirm whether VAT is included.

Is Re-Felting the Best Option?

Replacement is not always necessary, but repeated patching can become poor value. A repair may be suitable when:

• The damage is restricted to one small area
• Most of the existing roof remains in good condition
• The substrate beneath the leak remains suitable
• The roof has not already received numerous repairs

A full replacement may be more suitable when:

• The felt is failing across a large area
• Several joints and edges have started to fail
• The covering has become brittle or badly weathered
• There is extensive timber damage
• The roof requires structural correction to drain properly
• The insulation needs to be upgraded
• Continued patching is unlikely to provide lasting value

How Durable Is a New Felt Roof?

A professionally installed multi-layer felt roof can provide many years of service. A good-quality system may last for several decades under suitable conditions.

The serviceable life can be influenced by:

• The grade of membrane selected
• The standard of installation
• Whether the deck has suitable falls
• The level of weather exposure
• The amount of foot traffic or equipment on the roof
• How often drainage points are cleared
• Regular checks after severe weather

Felt Roof Guarantees in Oxfordshire

Roofers may provide different workmanship and material warranty periods. Before appointing a contractor, ask:

• How many years the installation is guaranteed for
• Whether materials and labour are both covered
• Whether the guarantee comes from the contractor or manufacturer
• Whether independent warranty protection is available
• What exclusions apply
• What happens when the property is sold

Getting Ready for Re-Felting

A little preparation can help the roofing work run more smoothly. This may include:

• Keeping the driveway clear for the contractor
• Removing valuable or fragile items from the building
• Providing access to electricity or water where agreed
• Discussing shared access in advance
• Preventing access to ladders, scaffolding and roofing materials
• Checking whether planning or building control requirements apply
• Understanding temporary weatherproofing arrangements

Finding a Suitable Roofer

Receiving more than one quotation can help you compare the proposed work and roofing specification. Do not compare only the final price.

Check whether each quotation includes:

• Stripping and disposal of old roofing materials
• Details of how hidden timber damage will be priced
• The full roofing specification
• The type and thickness of insulation
• The treatment of vulnerable junctions
• Scaffolding or access equipment
• Disposal of old felt and damaged timber
• How weather delays will be handled
• VAT
• Workmanship and material warranty details

You should also consider:

• Whether the contractor's insurance is valid and appropriate
• Experience with similar felt roofing projects
• Reviews from completed projects
• Whether appointments and quotations are handled professionally
• Payment terms

Frequently Asked Questions

How long does felt roof replacement take in Oxfordshire?

Smaller felt roof replacements may be completed in one day. More extensive replacement work can require several working days. The timeframe may increase when significant decking or joist repairs are needed. The contractor should explain the expected duration after inspecting the roof.

Can new felt be installed over the old roof?

Overlaying may be considered when the existing system is dry, stable and properly bonded. However, stripping the old felt allows the decking and hidden damage to be inspected. Ask the roofer to explain whether the existing roof is suitable to remain.

What is the best felt for a replacement roof?

The contractor should recommend a system suited to the roof and how the building is used. Professional garages and extension roofs commonly use reinforced two-layer or three-layer felt systems. Basic shed felt is generally less durable than a professional reinforced system.

How long should a new felt roof last?

A high-quality reinforced felt roof should normally outlast basic roofing felt. Its lifespan depends on installation quality, drainage and maintenance. The contractor should explain which guarantee is included.

Will damaged roof boards be included in the quote?

Roof board replacement may be included up to a stated amount or priced as an additional item. Because the full condition of the deck may not be visible until the felt is removed, ask the contractor to state how additional decking will be charged.

Can insulation be upgraded during felt roof replacement?

A complete re-felt often provides an opportunity to install a warm roof system. This is particularly relevant where the replacement work is subject to current thermal requirements. The contractor should explain the proposed insulation thickness and roof build-up.

Does felt roof replacement require planning permission?

Routine re-felting normally falls within property maintenance rather than a planning application. Different requirements may apply where the work forms part of a larger extension, conversion or roof terrace. The property owner should check with the relevant local authority where there is any uncertainty.

Will Building Regulations apply?

More extensive re-roofing work can trigger requirements relating to insulation and thermal performance. Minor repairs may be treated differently. Ask the contractor whether insulation upgrades are included in the specification.

Can a felt roof be replaced during winter?

Felt roof replacement can be carried out during colder months when conditions are suitable. The contractor may use temporary protection between stages. Discuss whether additional temporary covering is included.

How much deposit should I pay?

A contractor may request a reasonable deposit to secure materials and the start date. Before paying, check the business details and ask for a receipt. Avoid accepting unexpected changes to bank details without checking them directly.
