Give sheds, summerhouses, garden offices, log cabins and other pitched garden buildings a smart, professional roof finish with these Green 3-Tab Square Reinforced Fibreglass Roofing Shingles.
Manufactured using a lightweight glass fibre-based bitumen construction, these durable roof shingles combine an attractive green mineral finish with a classic 3-tab square pattern, creating the appearance of individual roof tiles without the weight associated with traditional clay, concrete or slate roofing.
Each pack provides approximately 3m² of finished roof coverage and contains 21 individual 1 metre-long shingle strips, making them an excellent choice for decorative garden buildings, sheds, summerhouses, workshops, chalets, stables and similar pitched roofing applications.
Green 3-Tab Roofing Shingles
The traditional 3-tab square design creates a clean, regular tiled appearance across the roof.
Once installed in overlapping courses, each strip forms three visible rectangular tabs, producing a neat geometric pattern that works particularly well with both modern and traditional garden buildings.

3m² Coverage Per Pack
Each pack provides approximately 3 square metres of finished roof coverage when the shingles are installed with the correct overlaps.
The pack contains 21 individual shingles, allowing installers to build up the roof surface in overlapping horizontal courses.
When calculating the number of packs required, remember that the stated 3m² figure is the intended installed coverage.
It is still sensible to allow some additional material for:
- Cutting
- Roof edges
- Verges
- Eaves
- Ridge details
- Unusual roof shapes
- Valleys where applicable
- Installation waste
21 Shingles Per Pack
Each pack contains 21 individual 3-tab shingle strips.
This makes it straightforward to calculate the quantity needed for a particular roof once the total roof area has been measured.
For larger buildings, multiple packs can be combined to cover the complete roof.
100cm Long Shingle Strips
Each shingle strip measures approximately 100cm long.
The one-metre strip format makes installation much faster than positioning individual small tiles while still producing the visual appearance of multiple separate roofing elements.
The strips are installed in overlapping rows across the roof slope.
Approximately 30cm Actual Coverage Depth
Each shingle provides approximately 30cm of actual vertical roof coverage once the required overlap has been taken into account.
Overlapping is a fundamental part of shingle roofing because it helps:
- Protect joints
- Cover mechanical fixings
- Encourage rainwater to run down the roof
- Improve weather resistance
- Create the characteristic layered appearance
Correct overlap and alignment are essential for a professional installation.
Classic 3-Tab Square Design
The 3-tab square profile produces a clean, consistent appearance across the roof.
Each shingle strip creates three visible rectangular sections once installed.
This gives the completed roof a traditional tiled effect without requiring individual heavyweight roof tiles.
The pattern works particularly well on:
- Garden sheds
- Summerhouses
- Garden offices
- Log cabins
- Workshops
- Chalets
- Timber garages
- Playhouses
Attractive Green Mineral Finish
The green finish makes these shingles especially suitable for timber buildings and landscaped garden environments.
Green roofing complements:
- Natural timber
- Brown timber stain
- Log cabins
- Green-painted buildings
- Garden rooms
- Woodland-style surroundings
- Rural outbuildings
The mineral-finished surface also provides the attractive exposed face of the finished roofing system.
Reinforced Fibreglass Construction
These roofing shingles use a reinforced glass fibre-based construction.
Fibreglass provides good dimensional stability while keeping the roofing material relatively lightweight.
Benefits include:
- Lightweight handling
- Good strength-to-weight ratio
- Dimensional stability
- Straightforward cutting
- Easy transportation
- Reduced structural load compared with many traditional roofing materials
This makes reinforced fibreglass shingles particularly well suited to timber garden buildings.
Lightweight Alternative to Traditional Tiles
Traditional clay, concrete and slate roofing can place a significant load on a roof structure.
Fibreglass shingles provide a substantially lighter alternative for suitable buildings.
This can make them ideal for:
- Sheds
- Summerhouses
- Garden rooms
- Log cabins
- Workshops
- Chalets
- Kennels
- Timber outbuildings
The supporting roof structure must still be correctly designed and structurally sound.
Professional Tiled Appearance
One of the main reasons customers choose 3-tab shingles is appearance.
Standard roll roofing felt creates a relatively flat finished surface.
3-tab shingles create a much more decorative, layered look that resembles traditional individual roofing tiles.
This can dramatically improve the finished appearance of a garden building.
Ideal for Shed Roofs
These Green 3-Tab Square Shingles are an excellent upgrade for a pitched garden shed.
They are ideal for:
- Apex sheds
- Tool sheds
- Storage sheds
- Large timber sheds
- Premium garden buildings
Compared with basic roll roofing felt, shingles create a more decorative and substantial-looking roof.
Ideal for Summerhouses
Summerhouses are particularly well suited to decorative roofing shingles.
The green tiled effect complements natural timber while creating a high-quality finished appearance.
For the best overall look, matching green ridge shingles can be used at the roof apex.
Excellent for Garden Offices
Modern garden offices frequently benefit from a more attractive roofing finish than conventional shed felt.
Green 3-tab fibreglass shingles provide a neat tiled effect suitable for:
- Garden offices
- Home studios
- Garden rooms
- Hobby rooms
- Work-from-home buildings
- Timber studios
Suitable for Log Cabins
Green shingles are particularly attractive on log cabins.
The green mineral finish contrasts naturally with timber walls while fitting comfortably into garden surroundings.
The lightweight construction also makes fibreglass shingles a practical choice for many timber cabin roofs.
Suitable for Chalets & Garden Buildings
Other suitable applications can include:
- Chalets
- Beach huts
- Playhouses
- Workshops
- Timber garages
- Garden stores
- Kennels
- Stables
- Other suitable pitched timber buildings
Always ensure the roof structure and pitch are appropriate for shingle installation.
Hot or Cold Bitumen Bonding
Unlike the hexagonal shingles in the Felt Products range, this 3-tab product is not marketed around a peel-off adhesive backing.
The specified fixing system uses:
Hot-applied bitumen or cold bitumen mastic together with galvanised ELH clout nails.
For many DIY and general building applications, a compatible cold bitumen mastic may provide a convenient bonding method where permitted by the installation specification.
Where hot application is used, appropriate training, fire precautions and suitable roofing equipment are essential.
Galvanised Extra Large Head Clout Nails
Mechanical fixing is an important part of the shingle installation.
Suitable galvanised Extra Large Head — ELH — clout nails should be used.
Their wider heads help spread pressure across the shingle and reduce the likelihood of the fixing pulling through the material.
Benefits include:
- Strong mechanical fixing
- Improved resistance to wind movement
- Large fixing surface
- Reduced risk of pull-through
- Galvanised corrosion resistance
Use Over a Suitable Roofing Underlay
Roofing shingles form the decorative outer roof layer.
They should be installed over an appropriate roofing underlay where required by the roof specification.
Suitable underlay helps:
- Provide additional weather protection
- Protect the roof deck
- Create a secondary barrier beneath the shingles
- Improve the complete roofing system
- Reduce the consequences of minor water penetration
Prepare the Roof Deck Correctly
The roof deck should be:
- Structurally sound
- Smooth
- Clean
- Dry
- Firm
- Free from loose nails
- Free from protrusions
- Correctly prepared before installation
Poor preparation can affect both the appearance and long-term performance of the finished roof.
Install from the Eaves Upwards
Roofing shingles are normally installed beginning at the lower edge of the roof and working upwards towards the ridge.
Successive courses overlap the rows beneath them.
This creates a layered arrangement that encourages rainwater to flow:
ridge → down across the shingles → towards the eaves
rather than underneath the roofing material.
Stagger the Shingle Courses
Successive rows should be correctly offset so that joints do not align vertically.
Correct staggering helps:
- Cover joints
- Improve weather protection
- Produce the correct tiled appearance
- Create a professional pattern
- Avoid continuous vertical water paths
Keep the First Course Straight
Accurate installation of the first course is important because subsequent rows follow its alignment.
Before permanently fixing the first shingles:
- Check the roof is square
- Establish a straight reference line
- Position the starter course correctly
- Check the required eaves overhang
- Confirm alignment from one side of the roof to the other
A small alignment error at the first row can become much more noticeable higher up the roof.
Protect Mechanical Fixings
Where possible within the specified installation pattern, nails should be positioned so that the next overlapping course protects the fixing area.
This helps create a cleaner finished appearance and reduces direct weather exposure around fixings.
Complete the Roof with Green Ridge Shingles
The 3-tab shingles cover the main roof slopes, but the apex requires a suitable ridge detail.
Matching Green Reinforced Fibreglass Ridge Roofing Shingles can provide a coordinated finish.
A complete green shingle roofing system can therefore include:
- Roofing underlay
- Green 3-tab square shingles
- Green ridge shingles
- Galvanised ELH clout nails
- Compatible cold bitumen mastic or specified bonding product
Excellent Internal-Linking Opportunity
For SEO and customer convenience, this product page should link directly to:
- Green ridge shingles
- Roofing underlay
- Galvanised ELH clout nails
- Roofing felt adhesive / suitable bitumen mastic
- Other 3-tab shingle colours
This helps customers purchase the complete roof system while strengthening the internal SEO structure of the roofing-shingle category.
3-Tab vs Hexagonal Roofing Shingles
Felt Products offers both 3-tab square and hexagonal roofing shingles.
The key difference is the finished appearance.
3-Tab Square Shingles
- Straight rectangular tabs
- Clean geometric appearance
- Traditional tiled effect
- Works well on modern and traditional buildings
Hexagonal Shingles
- Decorative hexagonal lower edge
- More distinctive pattern
- Popular on summerhouses and log cabins
Both are lightweight reinforced fibreglass roof coverings.
Green vs Black or Red Shingles
Colour is another important consideration.
Green roofing shingles work particularly well with:
- Timber structures
- Landscaped gardens
- Rural surroundings
- Natural-coloured buildings
Black shingles offer a darker contemporary appearance, while red shingles create a warmer traditional tiled effect.
Giving each colour its own optimised product page can help capture colour-specific searches.
Suitable for New Roofs
These shingles are ideal for new roofing projects such as:
- New sheds
- Summerhouses
- Garden offices
- Log cabins
- Chalets
- Workshops
- Playhouses
- Timber outbuildings
Ordering underlay, main shingles, ridge pieces and fixings together helps make installation more straightforward.
Suitable for Refurbishment
Green 3-tab shingles can also be used when upgrading an appropriate existing roof.
They are particularly useful where the existing covering has become:
- Worn
- Damaged
- Unattractive
- Weathered
- Loose
- In need of replacement
Always inspect and repair the underlying roof deck before installing the new roofing system.
