Re-felting is a regularly requested roofing service among homeowners and property managers in County Tyrone. Thousands of flat and low-pitched roofs in County Tyrone are protected by bitumen felt systems. Over time, the covering can become brittle, cracked or difficult to repair economically.

We help homeowners, landlords and businesses find roofing contractors who carry out felt roof replacement throughout County Tyrone. Depending on local availability, your enquiry can be matched with up to four roofing specialists. There is no charge for requesting quotations and no obligation to proceed.

Signs That a Felt Roof May Need Replacing

Minor defects can often be repaired if the rest of the roofing system is still in reasonable condition. However, replacement may provide better long-term value when damage is widespread.

Roofers working in County Tyrone regularly inspect roofs with brittle felt, open joints and damaged decking. A professional inspection can help establish the most suitable solution for the condition of the existing roof.

Signs that a felt roof may need replacing include:

• Cracking across large areas of the felt
• Several recurring leaks
• Large areas where the felt has lifted from the layer below
• Loose, open or failing seams
• Roofing felt pulling back from perimeter details
• A cap sheet that looks smooth, worn or heavily weathered
• Persistent standing water caused by poor roof falls
• Damaged timber boards beneath the covering
• Old felt systems that have been repeatedly overlaid
• An ageing roof with little serviceable life remaining

The Felt Roof Replacement Process

Complete felt roof replacement normally involves stripping the old system and rebuilding the waterproof covering. The exact method will depend on the roof structure, existing materials and chosen specification.

Surveying the Existing Roof

The first stage is usually an inspection of the existing roof and its access requirements. The survey may consider:

• The age and condition of the existing felt
• Whether the roof has been overlaid previously
• Visible signs of rotten or damaged roof boards
• Standing water and drainage performance
• Wall junctions, kerbs and perimeter details
• How the contractor can work safely around the roof
• Insulation and condensation risks

Stripping the Old Felt

A full replacement generally starts with removing the worn felt system. This allows the contractor to identify hidden damage and prepare a clean surface.

The work may include:

• Stripping previous felt and patch repairs
• Removing loose or unsuitable roofing accessories
• Clearing old adhesives, debris and loose material
• Using temporary coverings where necessary
• Arranging responsible disposal of old materials

Roof Deck and Timber Repairs

The roof deck must be firm, dry and suitable for the new system. Contractors may need to:

• Remove and replace unsuitable timber boards
• Repair or strengthen damaged joists
• Create or improve the roof fall
• Repair rooflight kerbs and edge details
• Correct uneven or sagging areas
• Deal with localised timber deterioration

Adding Insulation During Replacement

When the roof covers a heated room, replacement may provide an opportunity to improve insulation. Depending on the building and applicable requirements, the work may include:

• Creating an insulated warm roof system
• Renewing ineffective insulation materials
• Installing a suitable vapour control layer
• Adjusting roof features to suit thicker insulation
• Reducing the risk of condensation beneath the decking

Installing the New Felt Roofing System

The new covering will normally consist of several compatible roofing layers. Depending on the chosen specification, this can include:

• Applying a suitable bitumen primer
• A base layer fixed to the deck
• A second waterproofing layer
• A durable external membrane designed to resist weathering
• Torch-on application where suitable
• Flame-free roofing methods for sensitive sites

Completing Perimeter and Junction Work

Correct detailing around the perimeter is essential to prevent water ingress. The contractor may complete:

• Vertical felt details at abutments
• Weatherproofing over wall junctions
• Drip edges and fascia details
• Weatherproofing around parapet walls
• Replacement felt details around glazed roof openings
• Pipe, vent and cable penetrations
• Low upstands around accessible roof areas

Finishing Gutters and Rainwater Outlets

The completed roof should direct water towards suitable drainage points. The contractor may:

• Remove debris from drainage points
• Renew leaking or unsuitable roof outlets
• Replace gutters and downpipes where included
• Correct low areas in the deck
• Add secondary drainage to suitable commercial or parapet roofs

Final Checks and Site Clearance

The finished roof should be checked before the project is handed over. The contractor may also:

• Leave the working area reasonably clean and tidy
• Check gutters and outlets
• Record the completed work
• Hand over guarantee documents and product details
• Explain any maintenance recommendations

Choosing a Replacement Felt System

Multi-Layer Torch-On Systems

Torch-on felt is one of the most widely used systems for garages, extensions and commercial flat roofs. The layers are heat-welded to form a continuous waterproof covering.

The final specification can include a bonded base sheet, waterproof underlay and protective mineral surface. Torch-on work should be carried out with suitable fire precautions and insurance.

Flame-Free Felt Systems

Some reinforced membranes are bonded using cold-applied roofing adhesives. These systems may be suitable for timber structures, restricted sites and sensitive locations.

Peel-and-Stick Roofing Membranes

Peel-and-stick felt can provide another flame-free installation method. Proper surface preparation remains important, and laps, corners and edges must still be finished carefully.

Protective Cap Sheet Finishes

Professional felt roofs often finish with a protective mineral cap sheet. This surface helps protect the bitumen membrane from sunlight and general wear.

Comparing Felt with Other Systems

A complete replacement can provide an opportunity to consider several flat roofing systems. Alternatives may include:

• EPDM rubber roofing
• Glass-reinforced plastic roofs
• Cold-applied liquid roof systems
• Single-ply membranes
• Traditional asphalt flat roofing

A roofing contractor can explain how felt compares with other systems for the particular building.

Felt Roof Replacement Costs in County Tyrone

Re-felting costs across County Tyrone vary according to the building, materials and condition of the existing roof. The final quotation may be affected by access, waste removal, flashing and drainage improvements.

These figures are broad estimates and should not be treated as fixed quotations. For accurate local pricing, request no-obligation quotes from felt roofing contractors working in County Tyrone.

Why Felt Roofing Quotes Can Vary

• Roof area: Larger roofs require more felt, timber, insulation and labour.
• Roof shape: A simple rectangular roof is generally cheaper than a roof with several sections.
• Existing roof layers: Previous coverings and patch repairs can make preparation more involved.
• Decking condition: Rotten or damaged boards must normally be replaced.
• Structural timber: Weak supporting timbers may require additional work.
• Insulation: Thermal upgrades may form a significant part of the quotation.
• Felt specification: Premium reinforced systems usually cost more than basic coverings.
• Access: Limited access can affect waste removal and material handling.
• Scaffolding: Some projects require a tower, scaffold or lifting equipment.
• Rooflights and penetrations: Each rooflight, pipe and vent requires careful waterproofing.
• Flashing and edges: Wall junctions and roof edges may require replacement.
• Drainage: Gutters, outlets and downpipes may need renewal.
• Waste removal: Stripped felt and damaged timber must be removed responsibly.
• Location: Prices may differ between larger towns and rural locations.
• VAT: The final amount may differ depending on the contractor's VAT status.

Repairing or Replacing a Felt Roof

A contractor should consider the whole roof rather than only the visible leak. A repair may be suitable when:

• The leak has a clear and localised cause
• The surrounding felt remains flexible and secure
• There is no widespread timber damage
• There is no long history of repeated failure

A full replacement may be more suitable when:

• Cracking and deterioration affect several parts of the roof
• Water ingress returns after repairs
• The roof surface is heavily worn
• The roof deck is rotten or sagging
• Standing water affects several areas
• The roof build-up no longer meets the needs of the building
• The cost of further repairs would represent a large part of the replacement price

Expected Lifespan of Re-Felting

Modern reinforced felt systems generally last longer than basic shed felt. A good-quality system may last around 15 to 30 years when correctly installed and maintained.

The serviceable life can be influenced by:

• The specification of the roofing system
• The quality of workmanship
• Roof drainage and standing water
• Local weather and environmental conditions
• Damage caused by maintenance access or stored items
• Maintenance of gutters and outlets
• How quickly small problems are addressed

What Roofing Guarantees May Cover

The guarantee offered will depend on the contractor and roofing system. Before appointing a contractor, ask:

• What period of workmanship cover is included
• Whether the warranty applies to the complete roofing system
• Who provides the guarantee
• What happens if the contractor stops trading
• Whether standing water, damage or unauthorised repairs affect the cover
• Whether the guarantee can transfer to a future owner

What Homeowners Should Do Before Work Starts

The contractor should explain any access or preparation requirements before the start date. This may include:

• Moving vehicles away from the working area
• Protecting stored items beneath the roof
• Discussing site requirements before work begins
• Informing neighbours where scaffolding or access may affect them
• Making sure the site remains clear
• Discussing insulation and Building Regulations with the contractor
• Agreeing how the building will be protected if weather changes

How to Compare Re-Felting Specialists

Comparing several roofers can help you understand the likely cost and available options. Do not compare only the final price.

Check whether each quotation includes:

• Removal of the existing felt
• An allowance for rotten roof boards
• A clear description of the proposed membrane system
• Insulation and vapour control work
• Work around walls, rooflights and outlets
• Any additional access charges
• Waste removal and site clearance
• An estimated programme for the work
• The contractor's VAT status
• Guarantee information

You should also consider:

• Evidence of suitable insurance cover
• Whether the roofer regularly installs the proposed system
• Recent customer references
• How clearly the contractor answers questions
• Whether staged payments are reasonable

Frequently Asked Questions

How long does felt roof replacement take in County Tyrone?

A standard single garage roof can often be replaced within one or two working days. A bigger domestic flat roof may take between three and six days. The timeframe may increase when access is difficult or bad weather interrupts the work. The contractor should provide a realistic programme with the quotation.

Can new felt be installed over the old roof?

Some contractors can install a new layer over a suitable existing covering, although the roof must first be assessed. However, several previous layers may make another overlay unsuitable. Ask the roofer to explain why stripping or overlaying is recommended.

What is the best felt for a replacement roof?

There is no single felt specification that suits every roof. A mineral-finished multi-layer system is a common choice for domestic and commercial roofs. Basic shed felt is normally intended for small, low-value outbuildings rather than heated rooms.

How long should a new felt roof last?

Modern multi-layer felt roofing can remain serviceable for several decades. Its lifespan depends on how well the roof is fitted and looked after. The contractor should explain the expected service life of the proposed system.

Will damaged roof boards be included in the quote?

The treatment of damaged decking varies between quotations. Because the full condition of the deck may not be visible until the felt is removed, ask the contractor to state what happens if extensive hidden damage is discovered.

Can insulation be upgraded during felt roof replacement?

Yes, replacing the roof can be a practical time to improve insulation. This is particularly relevant where the existing insulation is wet or inadequate. The contractor should explain how the new insulation affects kerbs, edges and outlets.

Does felt roof replacement require planning permission?

Straightforward like-for-like replacement will not usually require planning permission. Different requirements may apply where the roof height, shape or use will change. The property owner should seek advice before making significant external alterations.

Will Building Regulations apply?

Building Regulations may apply when a substantial part of a roof over a heated building is replaced. Minor repairs may be treated differently. Ask the contractor who will contact building control if necessary.

Can a felt roof be replaced during winter?

Winter replacement is possible, but the roof deck and roofing materials must be installed in appropriate conditions. The contractor may reschedule work if the surface is wet or frozen. Discuss what happens if bad weather delays the work.

How much deposit should I pay?

The amount requested will depend on the contractor and project size. Before paying, obtain a detailed written quotation and payment schedule. Avoid making a large bank transfer without a written agreement.
