Felt Roofing Surrey
Felt roofing remains a common covering for residential flat roofs, including garages, extensions and other low-pitched roof areas. JB Roofing & Guttering provides flat roofing services across Surrey, helping homeowners discuss the condition of existing felt roofs and possible repair or replacement work.
Felt Roof Coverings for Surrey Homes and Garages
Felt roofing is widely associated with flat roofs on garages, extensions, porches and similar structures. Modern built-up felt systems differ from older, basic coverings and are designed around multiple layers of roofing material and appropriate weatherproof detailing.
The performance of a felt roof depends on more than the covering itself. Preparation of the supporting surface, suitable roof falls, effective drainage and properly formed edges and junctions are all important.
Existing felt roofs may develop problems over time, particularly where materials have deteriorated or vulnerable details have become damaged.
JB Roofing & Guttering is based in Weybridge and covers Surrey, including Guildford, Woking, Epsom, Reigate, Camberley and Farnham.
What Is a Modern Felt Roofing System?
Modern felt roofing commonly uses reinforced bituminous membranes arranged as a built-up system. The specification and number of layers depend on the particular roofing system.
The layers work together to provide a weather-resistant covering. However, details around roof edges, outlets, upstands and junctions remain important.
Different products have different installation requirements, and the condition of the roof deck can influence what work is suitable.
A felt covering should therefore be considered as part of the overall roof construction, rather than in isolation.
Problems That Can Develop on Older Felt Roofs
The condition of an existing felt roof can vary considerably depending on its age, installation, exposure and previous maintenance.
Cracking and Splitting
Older or deteriorating coverings can develop cracks or splits that may compromise the waterproofing layer.
Lifting and Failed Seams
Areas where felt layers or joints have lifted may become vulnerable to water penetration.
Blistering and Raised Areas
Raised areas can develop where moisture or air becomes trapped beneath parts of the covering. The cause and extent need assessing.
Damaged Edges and Flashings
Problems around roof perimeters, wall junctions and outlets can allow water ingress even where much of the main covering remains intact.
If your felt roof is leaking, our dedicated leaking flat roof repairs page explains why the source of water ingress may not be immediately obvious.
Can an Existing Felt Roof Be Repaired?
A localised defect in a felt roof may sometimes be repairable when the surrounding covering remains in suitable condition.
Where deterioration affects large sections of the roof, or leaks repeatedly return, replacing the covering may be more appropriate.
When a Repair May Be Considered
- The defect is confined to a limited area.
- The adjacent felt remains in reasonable condition.
- The source of the problem can be identified.
- There is no evidence of widespread underlying deterioration.
When Replacement May Be Considered
- There is extensive cracking or splitting.
- Leaks recur in multiple locations.
- Large areas of the covering have deteriorated.
- The roof deck or other components require substantial work.
Why Preparation, Drainage and Roof Details Matter
A new felt covering needs a suitable supporting surface and correctly designed details around the roof perimeter.
Where a roof has suffered repeated water ingress, the condition of the deck and insulation may need further investigation.
Water should also have an appropriate route towards roof outlets or gutters. Persistent standing water can indicate a problem with roof falls or drainage.
Correcting an underlying drainage problem may be just as important as replacing a worn covering.
Flat Roof Drainage ProblemsFelt Roofing on Garages and Home Extensions
Garages and extensions are common locations for felt roof coverings. However, the surrounding construction and drainage arrangements can differ.
Garage roofs may have relatively simple layouts, while extensions can include junctions against the main property, rooflights and additional detailing.
The existing roof construction should be considered when deciding on repairs or a replacement covering.
Is Felt the Only Option for a Flat Roof?
No. Other established flat roofing materials include EPDM rubber membranes and GRP fibreglass systems.
These coverings use different materials and installation methods. Their suitability depends on the roof's construction and requirements.
Read our separate guides to EPDM rubber roofing and GRP fibreglass roofing for more information.

View Areas CoveredFelt Roofing Questions
Is modern felt roofing different from older felt coverings?
Modern built-up felt systems often use reinforced bituminous membranes and specified installation methods. The particular products and system determine how the covering is constructed.
Can a cracked felt roof be repaired?
Sometimes. The suitability of a repair depends on the location of the crack, the condition of the surrounding felt and whether deterioration extends beyond the visible defect.
Why is my felt roof blistering?
Blistering can develop where moisture or air becomes trapped within or beneath parts of a roofing system. The cause and extent should be assessed before deciding what action is required.
Should an old felt roof be replaced with felt again?
Not necessarily. The appropriate covering depends on the roof's construction, condition and intended specification. Felt, EPDM and GRP systems have different characteristics.
Does a leaking felt roof always need replacing?
No. A localised defect may be repairable where the covering remains sound. Widespread deterioration or repeated failures may make replacement a more appropriate consideration.
