Give sheds, summerhouses, garages and garden buildings long-lasting waterproof protection with this Ultimate Quality Charcoal Polyester Shed Roofing Felt, supplied in a substantial 20m x 1m roll.
Manufactured using a strong SBS-modified polyester base, this premium shed roofing felt offers greater strength, flexibility and durability than traditional glass fibre shed felts. The upper surface is finished with an attractive granite grey / charcoal mineral slate, giving the completed roof a smart, professional appearance while providing a durable exposed roofing finish.
Designed to be installed as a single-layer waterproof roofing system, this 20 metre roll is an excellent choice for larger sheds, summerhouses, home offices, log cabins, garages and other timber garden buildings.
For customers looking for a more durable alternative to standard shed roofing felt, polyester mineral felt provides a significant upgrade.
The polyester reinforcement gives the membrane additional strength and flexibility, helping it withstand handling during installation and normal movement once installed.
This product is particularly suitable for customers searching for:
Unlike basic shed felts manufactured with a glass fibre core, this premium roofing felt uses a polyester-based reinforcement.
Polyester provides excellent tensile strength and flexibility, making the felt tougher and more resistant to tearing during handling and installation.
This makes it particularly suitable for customers wanting a roofing system that provides a step up from standard entry-level shed felt.
The membrane uses SBS-modified bitumen, which improves flexibility compared with more basic roofing felt formulations.
SBS modification allows the felt to remain flexible in colder temperatures and reduces the tendency for the material to become brittle.
This product is specified as remaining flexible down to approximately -15°C, making it particularly well suited to the changing temperatures experienced in the UK.
Cold weather can be challenging for lower-grade roofing materials.
Some basic felts can become stiff or brittle when temperatures fall, increasing the possibility of cracking or damage.
This SBS polyester roofing felt remains flexible down to approximately -15°C, helping maintain performance through colder weather conditions.
That additional flexibility is one of the main advantages of choosing a high-quality polyester shed felt.
The top surface is finished with a granite grey mineral slate, commonly described as a charcoal finish.
This provides a smart, understated appearance that complements both traditional and contemporary garden buildings.
The charcoal / granite grey colour works particularly well with:
The mineral finish also creates the exposed outer surface of the roofing system.
Each roll measures 20 metres long by 1 metre wide, giving approximately 20m² of material before allowing for overlaps, edges and cutting.
The long 20 metre format is particularly useful for larger roofing projects where multiple shorter rolls would otherwise be required.
It can help reduce the number of roll changes and potentially reduce the number of joints required across larger roof areas.
The generous 20m roll length makes this product especially suitable for:
For smaller projects, a 10m version may provide a more economical quantity.
This Ultrapol felt is designed to be used as a single-layer waterproof roofing system.
This makes installation relatively straightforward compared with traditional multi-layer roofing systems.
When installed correctly over a suitable roof deck, the felt forms the exposed waterproof layer and protects the building beneath from rain and everyday weather exposure.
One of the strongest selling points of this premium shed felt is its stated 15-year life expectancy when correctly installed.
That makes it an excellent choice for customers who want a longer-lasting roofing solution than basic glass fibre shed felt.
Correct installation is essential to achieving the expected service life.
The roof deck, overlaps, edges, fixings and adhesive details should all be completed carefully and in accordance with appropriate roofing practice.
The underside of the roofing felt features a film-faced finish.
Importantly, this film is part of the roofing product and should not be peeled off during installation.
The felt should be installed with:
Removing the film backing is not part of the installation process.
This polyester roofing felt is an excellent upgrade when replacing older or damaged shed felt.
It may be particularly suitable when an existing roof has become:
Replacing an ageing basic felt with a premium SBS polyester roofing felt can provide a longer-lasting roof covering.
The product is particularly well suited to timber garden sheds, providing a tough waterproof covering with a smart charcoal mineral finish.
Its polyester reinforcement and SBS modification make it an excellent option for customers looking for greater durability than standard shed felt.
Summerhouses often represent a greater investment than standard garden sheds, so customers may prefer a longer-life roofing material.
The attractive granite grey finish and 15-year expected life make this polyester felt a strong option for summerhouse roofs.
Garden offices and home workspaces frequently require a more substantial roofing solution because the building may be used throughout the year.
This premium polyester felt is ideal for:
Its charcoal / granite grey finish also complements contemporary timber garden buildings particularly well.
This roofing felt is also suitable for log cabin roofing applications.
The darker granite grey mineral finish provides an attractive contrast against natural timber, while the SBS polyester construction provides dependable waterproofing performance.
The 20m roll size makes this felt particularly useful for larger buildings such as:
For larger roof areas, the substantial roll size can make planning and installation more convenient than using several small rolls.
The recommended mechanical fixing method uses galvanised clout nails spaced approximately every 50mm.
Roofing clout nails feature a broad head that helps hold the felt securely against the timber roof deck.
The galvanised finish provides additional corrosion resistance for external roofing applications.
In addition to mechanical fixing, suitable roofing felt adhesive should be brushed along the edges.
Correct use of adhesive helps:
Particular attention should be given to exposed roof edges, joints and overlaps.
For best results:
Correct fitting is important for maximising waterproof performance and service life.
Although a 20m x 1m roll contains approximately 20m² of roofing material, the actual finished roof coverage will be lower because allowance must be made for overlaps and trimming.
When ordering, allow additional material for:
Measuring the roof accurately before ordering will help ensure enough felt is available to complete the installation correctly.
Both products can be suitable for garden building roofs, but they are aimed at different levels of performance.
Glass fibre shed felt is typically selected as an economical roofing solution for sheds and smaller garden buildings.
Polyester shed felt provides improved strength and flexibility and is better suited to customers looking for a more substantial and longer-lasting roof covering.
This Ultrapol product has a 15-year expected life, compared with the shorter expected lifespan typically associated with basic glass fibre shed felt.
Customers replacing an inexpensive shed roof covering may benefit from upgrading to polyester felt rather than simply installing another basic roofing membrane.
Key advantages include:
This makes the product particularly attractive for higher-quality sheds, garden offices, garages and summerhouses.
The felt is suitable for both new roofing installations and replacement roofing projects.
Typical applications include:
The Ultimate Quality positioning of this product reflects its heavier-duty polyester construction and long expected service life.
It is intended for customers who prioritise:
rather than simply choosing the lowest-cost shed felt available.
