Is It Time to Re-Felt Your Roof?

A small split or isolated leak may sometimes be repaired successfully. However, a complete re-felt may provide better value when the existing covering is failing throughout.

Property owners across Egham commonly request re-felting after repeated leaks or unsuccessful repairs. A professional inspection can help establish whether another repair is worthwhile or full replacement is required.

Common warning signs include:

• Felt that has cracked or pulled apart across several areas
• Several internal damp patches linked to the same flat roof
• A history of repeated patching
• Raised sections across much of the roof surface
• Several laps and joins losing their waterproof seal
• Felt pulling away from edges or walls
• Large areas where the protective mineral finish has disappeared
• Poor drainage affecting several parts of the roof
• Soft, rotten or sagging decking
• A roof that has been overlaid repeatedly
• A roof covering that is no longer likely to respond well to repair

What Is Involved in Felt Roof Replacement?

A complete re-felt should address the membrane, roof deck, insulation and vulnerable perimeter details. The precise method will depend on the contractor's inspection and the specification agreed with the customer.

Initial Roof Inspection

A roofer should assess the existing covering, drainage and access requirements before work starts. The assessment may include:

• Whether the existing covering is still repairable
• The number of old roofing layers
• Whether roof boards appear soft or uneven
• Whether poor falls are contributing to deterioration
• The condition of flashing and upstands
• Whether scaffolding or edge protection is needed
• The condition and suitability of the existing roof build-up

Removing the Existing Felt

Existing roofing layers are usually stripped back before the replacement system is installed. This allows the contractor to prepare a clean, dry and stable surface for the new membrane.

The work may include:

• Removing one or more layers of old felt
• Taking off damaged perimeter details
• Clearing loose material from the substrate
• Providing temporary protection where necessary
• Removing old felt from the site

Preparing a Sound Roof Deck

New felt should not be installed over rotten or unstable decking. The contractor may need to:

• Renew water-damaged roof boards
• Reinforce parts of the roof structure
• Fit new firring strips
• Renew perimeter timbers
• Prepare a smooth and stable surface
• Allow damp timbers to dry where necessary

Improving Flat Roof Insulation

Replacing a domestic flat roof may involve adding or renewing insulation. Depending on the roof and applicable requirements, the contractor may:

• Install rigid insulation above the roof deck
• Replace insulation damaged by leaks
• Improve condensation control within the roof build-up
• Raise rooflight kerbs and perimeter details
• Address airflow within the roof void

Applying a Multi-Layer Felt Roof

Professional felt roofs commonly use a reinforced two-layer or three-layer system. This can include:

• Preparing the deck with a compatible coating
• Applying a bonded, mechanically fixed or self-adhered base layer
• Laying a reinforced underlay
• Installing the exposed weatherproof top layer
• Applying controlled heat to bond the roofing system
• Using cold-applied or self-adhesive products where required

Finishing Vulnerable Roof Details

The replacement membrane must be properly finished around every interruption in the roof. Contractors may complete:

• Felt upstands against adjoining walls
• Replacement flashing above felt upstands
• Finished roof edges above fascia boards
• Rooflight and lantern kerbs
• Sealing around services passing through the roof
• Finishing felt around parapet walls
• Door thresholds and balcony junctions

Checking Flat Roof Drainage

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

• Clear existing roof outlets
• Install new drainage components
• Fit new guttering around garages and extensions
• Correct low sections of decking
• Install emergency overflow routes

Roof Handover and Guarantee

Once installation is complete, the contractor should inspect the finished roof. The contractor may also:

• Clear unused materials and debris
• Inspect rainwater goods before completion
• Provide photographs of the finished work
• Provide warranty and product information
• Provide guidance on future roof inspections

Types of Replacement Felt Available in Egham

High-Performance Torch-On Systems

Torch-on bitumen felt remains a common option for durable flat roofing. The layers are carefully heated and bonded together.

Professional specifications often contain two or three compatible layers. Contractors using direct heat should follow safe working methods for torch-applied roofing.

Cold-Applied Felt Roofing

Flame-free felt can be bonded without a gas torch. These options may suit properties where direct heat is considered unsuitable.

Self-Adhesive Felt Roofing

Some flame-free products attach directly to a properly prepared deck. The roof still needs professional detailing around edges, corners and penetrations.

Mineral-Surfaced Felt

Professional systems commonly use a mineral-surfaced cap sheet. It helps provide a hard-wearing finish for the roof.

Alternative Flat Roofing Systems

A complete replacement may provide an opportunity to compare felt with alternative systems. Options may include:

• Rubber flat roofing systems
• GRP fibreglass roofing
• Seamless liquid membranes
• Specialist sheet membrane systems
• Mastic asphalt roofing

Each system has different costs, installation requirements and maintenance needs.

Typical Felt Roofing Prices Across Surrey

The cost of felt roof replacement in Egham depends on the roof size, condition and chosen specification. The final quotation may be affected by the number of old roofing layers and hidden timber damage.

The table provides general guidance and does not replace a site-specific quote. To obtain accurate prices, submit a free enquiry and compare quotations from roofers serving Egham.

Why Felt Roof Replacement Quotes Vary

• Roof size: Material and labour costs normally increase with the square metre area.
• Roof shape: Several corners, levels or rooflights require more detailed work.
• Existing layers: A heavily overlaid roof may create additional waste.
• Decking condition: The quotation may change when defective decking is uncovered.
• Structural repairs: Damaged joists or supporting timbers add work.
• Insulation: Wet or inadequate insulation may need replacement.
• Felt specification: Premium reinforced membranes usually involve higher material costs.
• Access: Restricted access can increase labour and handling time.
• Scaffolding: Safe access equipment can add to the total price.
• Rooflights and penetrations: Complex roof features require additional materials and workmanship.
• Flashing and roof edges: New leadwork, trims or fascias may be needed
• Drainage: New outlets or guttering may increase the price.
• Waste removal: The amount of waste affects removal costs.
• Location: Labour and operating costs can vary within Surrey.
• VAT: VAT may be additional where the contractor is registered.

When Replacement Is Better Than Patching

The right option depends on the age of the roof, the extent of damage and the condition of the deck. A repair may still be suitable where:

• Only one seam, edge or section has failed
• The existing covering still has a reasonable expected lifespan
• The decking beneath the damage is sound
• Previous patching has been limited

A complete replacement may be more appropriate where:

• Widespread ageing is visible
• Leaks return after previous repairs
• The covering no longer remains flexible
• The substrate is no longer suitable for patch repairs
• Poor falls affect the whole roof
• Wet insulation needs to be removed
• A new system offers a more dependable long-term solution

How Long Does a New Felt Roof Last?

The lifespan of a replacement felt roof depends on the materials, workmanship and roof design. A good-quality system may remain serviceable for considerably longer than inexpensive shed felt.

Its lifespan may be affected by:

• The grade and number of roofing layers
• How carefully joints and edges are completed
• Persistent standing water and blocked gutters
• Sunlight, frost, wind and temperature changes
• Whether the roof is regularly walked on
• Whether debris is allowed to build up
• Prompt attention to minor defects

Workmanship Warranties and Material Cover

The cover offered will depend on the contractor and membrane specification. Before appointing a roofer, check:

• How long the workmanship guarantee lasts
• Which parts of the roof are covered
• Which organisation handles future claims
• Whether the guarantee is insurance-backed
• Whether standing water or third-party repairs affect cover
• Whether the warranty continues after a change of ownership

Preparing for Felt Roof Replacement

The contractor should explain any access and site requirements before starting. This can include:

• Providing space for vans, materials and waste removal
• Removing valuable items from garages or outbuildings
• Confirming whether electricity or water may be used
• Obtaining permission where neighbouring land is needed
• Keeping children and pets away from ladders and tools
• Confirming responsibility for Building Regulations
• Checking what happens if poor weather delays the project

Choosing a Felt Roofer in Egham

Different roofers may suggest different materials, insulation and preparation work. Do not judge quotations only by the final figure.

Check whether each quotation includes:

• Disposal of previous coverings and patch materials
• Inspection and replacement of damaged decking
• The number and grade of membrane layers
• Whether a warm roof upgrade is included
• Flashing, edges and upstands
• Safe working equipment
• Skip or collection costs
• The estimated start date and duration
• Whether the total includes VAT
• The provider and terms of the guarantee

You should also review:

• Current public liability insurance
• Examples of previous re-felting projects
• Feedback from customers with comparable properties
• Communication and reliability
• Whether staged payments are reasonable

Frequently Asked Questions

How long does felt roof replacement take in Egham?

Smaller porch, shed and garage roofs may be completed in one day. More complex projects may continue for most of a working week. The programme can be extended by rotten decking, structural repairs or difficult access. The contractor should include an estimated programme with the quotation.

Can new felt be installed over the existing roof?

Overlaying may be considered when the current felt is firmly bonded and free from trapped moisture. However, removing the old felt allows the roof deck to be inspected properly. Ask the contractor to explain how the condition of the deck has been assessed.

What type of felt is best for a replacement roof in Egham?

A contractor should recommend a membrane system appropriate for the particular roof. Professional garages and extensions commonly use reinforced two-layer or three-layer felt. Basic shed felt is generally less durable than a professional membrane system.

How long should a replacement felt roof last?

A good-quality multi-layer roof should normally last considerably longer than basic shed felt. Its useful life depends on the roofing specification, workmanship and drainage. Ask the contractor which workmanship and material guarantees are included.

Will the roofer replace damaged roof boards?

Roofers can replace damaged plywood or OSB before installing the new covering. The full condition may not be visible until the felt is removed, so quotations vary. Ask the contractor to state whether any board replacement is included.

Can insulation be added during the replacement?

A complete replacement over a heated room can include a warm roof upgrade. This is especially relevant where current thermal requirements apply to the work. The contractor should explain the insulation thickness and proposed roof build-up.

Does felt roof replacement require planning permission in Egham?

Routine re-felting without changing the roof shape or height is not normally a planning matter. Different rules may apply where the project includes a roof terrace, balcony, extension or conversion. Property owners should check with Surrey County Council where there is any uncertainty.

Will Building Regulations apply to the work?

More extensive re-roofing can trigger requirements relating to insulation and thermal performance. Minor repairs may be treated differently. Ask the roofer whether the quotation includes any necessary insulation work.

Can a felt roof be replaced in winter?

Roofers can replace felt roofs throughout the year when conditions are suitable. Contractors may use temporary coverings between stages. Confirm what happens if poor conditions interrupt the job.

How much deposit should I pay?

A contractor may request a reasonable deposit to secure materials and the start date. Before paying, check the contractor's business details and insurance. Avoid accepting changed bank details without verifying them independently.
