This page explains the most common garage roof materials in the UK, what they’re used for, and when they’re a good fit. If you already know what you want, you can request quotes for that system — or ask for advice and compare options.
Quick guide: which material suits which garage roof?
Garage roofs usually fall into one of two categories: flat (very common) or pitched (tiled/slated). Some garages also use corrugated sheets.
| Roof type | Common materials | Best for |
|---|---|---|
| Flat garage roofs | Modern felt, EPDM rubber, GRP fibreglass | Waterproofing, low maintenance, clean finish |
| Pitched garage roofs | Tiles, slate (less common), underlay systems | Traditional look, good longevity, easier local repairs later |
| Sheeted garage roofs | Corrugated sheets (various types including steel corrugated sheets) | Simple, practical roofs on older garages/outbuildings |
Flat garage roof materials
Modern felt (bitumen felt systems)
Modern felt is one of the most common choices for flat garage roof replacement because it offers strong value and a tidy finish.
Good for
- Cost-effective replacements
- Straightforward garage roof renewals
- Many garages where felt has been used historically
Things to know
- There are different felt systems; quality varies
- The lifespan depends heavily on installation and detailing
- Edge trims, corners and outlets are common failure points if poorly done
EPDM rubber roofing
EPDM is a rubber membrane used widely on flat roofs. It’s popular for homeowners who want a durable, low-maintenance option.
Good for
- Long-term durability
- Clean, modern look
- Lower maintenance compared to older felt systems
Things to know
- Correct edge/junction detailing matters
- The roof structure must be sound underneath
- Good drainage is still essential (ponding stresses any system)
GRP fibreglass roofing
GRP creates a hard-wearing surface and can look very neat on a garage roof when installed well.
Good for
- Tough finish and clean appearance
- Homeowners who want a “solid” feel
- Garages where a rigid surface is preferred
Things to know
- Installer quality is critical
- Trims and joins must be done correctly
- Some systems need the right conditions for curing
Pitched garage roof materials
Concrete or clay tiles
Many pitched garages use tiles similar to the main house roof (depending on age and build).
Good for
- Traditional look
- Easy local repairs (replace a few tiles)
- Strong longevity when maintained
Things to know
- The structure must be suitable for the weight
- Ridge/verge details often need maintenance over time
- Underlay and battens matter as much as the tiles
Slate (less common on garages)
Slate is more common on older homes and some older outbuildings, and it can appear on garage roofs in certain regions.
Good for
- Traditional properties
- Long lifespan
- A premium appearance (where appropriate)
Things to know
- Higher cost and specialist work
- Repair availability can vary depending on slate type
Corrugated and sheet garage roof materials
Sheeted garage roofs are common on older garages and some detached/outbuilding styles.
Corrugated sheets (various types)
These roofs are often practical and straightforward, but leaks can occur at fixings and overlaps as the roof ages.
Good for
- Simple garage roofs and outbuildings
- Practical replacements where appearance is less important
- Situations where the structure suits sheet roofing
Things to know
- Fixings and overlap details are common leak points
- Replacing damaged sheets early prevents timber issues
- It’s important to use the correct fixings and seals
Material comparison: what homeowners usually care about
This table helps homeowners compare options in a “real world” way.
| Material | Typical use | Why homeowners choose it | Watch-outs |
|---|---|---|---|
| Modern felt | Flat roofs | Value, familiar option, tidy finish | Needs good detailing at edges and outlets |
| EPDM rubber | Flat roofs | Durable, low maintenance | Edges/junctions must be done properly |
| GRP fibreglass | Flat roofs | Tough feel, clean look | Installer quality is key |
| Tiles | Pitched roofs | Traditional, easy local repairs | Ridge/verge maintenance, weight considerations |
| Slate | Pitched roofs | Premium look, long life | Higher costs, specialist work |
| Corrugated sheets | Sheeted roofs | Practical and simple | Fixing points and overlaps need proper sealing |
Which material is “best” for a garage roof?
There isn’t one best option for everyone. The best choice depends on:
- Your current roof type and structure (flat/pitched/sheeted)
- Whether you want a like-for-like replacement or an upgrade
- The condition of decking/timbers underneath
- Drainage and guttering setup
- Budget and the finish you want
If you’re not sure, request quotes and ask for recommendations based on your garage roof and priorities.
Common problems by material (helpful for diagnosis)
| Material | Common issues homeowners report | Typical solution |
|---|---|---|
| Older felt | Cracks, blisters, lifting edges | Repair if localised, replace if widespread |
| EPDM | Edge/junction leaks if detailing poor | Correct detailing, secure edges |
| GRP | Cracks at trims/joins if poorly installed | Repair/replace affected sections |
| Tiles | Slipped tiles, ridge/verge issues | Local tile/ridge/verge repairs |
| Corrugated sheets | Leaks at fixings/overlaps | Replace fixings or sheets as needed |

Garage roof materials FAQs
What’s the most popular material for a flat garage roof in the UK?
Modern felt, EPDM rubber and GRP fibreglass are all common. The best choice depends on budget, desired finish and the condition of the roof structure.
Is EPDM better than felt?
EPDM can be very durable and low maintenance. Modern felt can offer excellent value. Installation quality and detailing at edges, junctions and outlets matters for both.
Can I change my garage roof material when replacing it?
Often, yes — as long as the existing structure can support the new system and the roof is detailed correctly. A professional can confirm what’s suitable after inspection.
Are tiled garage roofs better than flat roofs?
Not necessarily. Pitched roofs shed water well and are easy to repair locally, but they also require maintenance at ridges/verges and can still leak. Flat roofs can be very reliable when properly installed with good drainage.
What if my garage roof is corrugated?
Corrugated roofs are common on older garages. Leaks often happen at fixings and overlaps. In many cases, local repairs are possible; if sheets are brittle or widely damaged, replacement may be better value.
