Give sheds, summerhouses, garden offices, log cabins and garages long-lasting waterproof protection with Ultrapol Charcoal Polyester Shed Roofing Felt, a premium 10m x 1m SBS-modified roofing felt designed for strength, flexibility and durability.
Manufactured using a tough polyester reinforced base rather than the glass fibre reinforcement found in more basic shed felts, Ultrapol provides a stronger and more flexible roofing solution for customers looking for a premium-quality garden building roof covering.
The upper surface is finished with an attractive charcoal / granite grey mineral slate, giving the completed roof a smart, professional appearance, while the film-faced underside helps the felt remain flat and manageable during installation.
Ultrapol is designed for customers who want a significant upgrade from standard shed roofing felt.
Its combination of polyester reinforcement and SBS-modified bitumen provides enhanced strength, tear resistance and flexibility while still allowing the product to be installed as a straightforward single-layer waterproof roofing system.
It is ideal for customers searching for:
The key difference between Ultrapol and basic shed roofing felt is the polyester reinforcement.
Traditional budget shed felts often use a glass fibre carrier. Polyester reinforcement offers greater strength and flexibility, helping the material resist tearing and cope more effectively with normal movement during handling and installation.
This makes Ultrapol particularly suitable for customers who want a roof covering that feels more substantial and is intended to last significantly longer than basic shed felt.
Ultrapol uses SBS-modified bitumen, which improves the flexibility of the roofing felt compared with more basic bituminous membranes.
This added flexibility is particularly valuable in the UK, where roofing materials are exposed to changing seasonal temperatures throughout the year.
SBS modification helps the felt remain flexible rather than becoming excessively stiff or brittle in colder conditions.
The current Ultrapol specification states that the felt remains flexible down to approximately -15°C.
This improved cold-weather flexibility helps reduce the risk of cracking or brittleness associated with lower-grade roofing products.
For garden buildings exposed to year-round British weather, this is an important advantage.
The top surface is finished with an attractive granite grey mineral slate, creating the charcoal appearance commonly preferred on modern garden buildings.
The dark neutral colour works particularly well with:
The mineral finish also forms the exposed weather-facing surface of the roofing membrane.
Each roll measures 10 metres long by 1 metre wide, providing approximately 10m² of material before overlaps, edges and cutting are taken into account.
The 10m size is particularly suitable for medium-sized garden buildings and standard shed roofing projects.
It offers a useful balance between coverage and ease of handling compared with heavier 20m rolls.
Each charcoal Ultrapol 10m roll weighs approximately 25kg.
This substantial weight reflects the heavier-duty polyester and bituminous construction while remaining more manageable than the larger 20m version.
Ultrapol is an excellent choice for customers who want a more durable shed roofing material than standard mineral felt.
It is particularly suitable for:
The charcoal mineral finish gives a neat final appearance while the SBS polyester construction provides dependable waterproof protection.
Summerhouses often represent a larger investment than a standard storage shed, making a longer-lasting roofing material worthwhile.
The attractive charcoal finish and 15-year life expectancy make Ultrapol particularly well suited to summerhouse roofing projects.
Garden offices and home workspaces are often occupied throughout the year and therefore benefit from a more substantial roofing system.
Ultrapol is suitable for:
The granite grey finish also complements contemporary garden office designs particularly well.
The strong polyester construction and dark mineral finish make Ultrapol an excellent option for log cabins and timber garden buildings.
The charcoal surface provides an attractive contrast against natural timber while offering dependable protection against rain and weather exposure.
Ultrapol can also be used on suitable garage and workshop roofs.
Typical applications include:
The premium polyester construction makes it particularly attractive where greater durability is preferred over basic economy shed felt.
Ultrapol is designed to be installed as a single-layer waterproof roofing felt.
This makes it straightforward to use compared with multi-layer felt systems while still providing premium performance for garden building roofs.
When correctly installed over a suitable roof deck, the membrane becomes the exposed waterproof roof covering.
One of the strongest selling points of Ultrapol is its stated 15-year life expectancy when correctly installed.
This gives customers a clear upgrade path from basic shed felts with shorter expected service lives.
Correct installation is essential to achieving the intended performance.
The roof deck, fixings, adhesive, overlaps, edges and ridge details should all be completed carefully.
The underside of the product features a film-faced finish.
This film is part of the roofing felt construction and must not be peeled off during installation.
Install the membrane with:
The film backing helps the product remain flat and manageable when laid.
The film-faced underside helps reduce unwanted sticking while the roll is stored and contributes to a flatter installation.
A roofing felt that lies flat is easier to position, align and secure correctly across the roof deck.
This can help produce a cleaner and more professional-looking finish.
Ultrapol is particularly useful when upgrading an older roof that has become:
Replacing worn basic felt with an SBS polyester roofing felt can significantly improve the durability of the finished roof.
The current installation specification calls for galvanised clout nails positioned approximately every 50mm.
Roofing clout nails feature broad heads that help secure the felt without easily pulling through the membrane.
The galvanised finish also provides greater corrosion resistance for exterior applications.
Suitable roofing felt adhesive should be applied along the edges as part of the installation.
Adhesive helps:
For best results, use a roofing adhesive compatible with bituminous roofing felt.
For best performance:
Correct installation is important for achieving maximum waterproofing performance and lifespan.
Although each roll contains approximately 10m² of material, the actual finished roof coverage will be lower because roofing felt must overlap at joints and edges.
Allow additional material for:
Accurate roof measurements before ordering will help ensure sufficient material is available.
For customers comparing roofing materials, the main difference is the reinforcement.
Glass fibre shed felt is generally an economical choice for standard garden building roofs.
Polyester shed felt provides improved tensile strength, flexibility and tear resistance, making it more suitable where longer service life and increased durability are required.
Ultrapol is therefore a strong choice for customers looking to upgrade from entry-level shed roofing felt.
Ultrapol provides several advantages over lower-cost shed felt:
This makes it particularly attractive for higher-quality sheds, summerhouses, garden offices, log cabins and garages.
Ultrapol is suitable for both new roofing installations and replacement roofing projects.
Typical uses include:
The Ultimate Quality description reflects the heavier-duty polyester construction and longer expected lifespan of Ultrapol compared with basic shed roofing membranes.
It is designed for customers who prioritise:
rather than simply selecting the lowest-cost roofing felt.
Choose Ultrapol Charcoal Polyester Shed Roofing Felt 10m x 1m for a strong, flexible and long-lasting premium roof covering designed for sheds, summerhouses, garden offices, log cabins, garages and other timber garden buildings.
