Flat Roofing in Menai Bridge
FlatRoof Masters provides specialist flat roofing in Menai Bridge for homes, holiday properties, landlords, businesses and managed buildings. We repair leaking flat roofs, replace failed coverings and install new systems on extensions, garages, dormers, balconies, porches and commercial roof areas.
Menai Bridge properties can have demanding roof details. Roofs beside the Menai Strait may be exposed to wind-driven rain, while extensions and older buildings often need careful work around wall junctions, parapets, outlets, rooflights and adjoining slate roofs. We inspect the actual roof before recommending a repair or replacement.

Is a Flat Roof Repair Enough, or Is Replacement Needed?
A repair is usually sensible where the defect is limited, the surrounding covering remains in good condition and the deck underneath is dry and stable. A split seam, puncture, failed outlet or isolated flashing problem can often be dealt with without replacing the full roof.
Replacement is normally the better investment when the roof has deteriorated across a wide area, water has reached the deck or insulation, several patches have already failed, or poor falls leave water sitting after rain. We explain what we find, why it matters and what the realistic options are.
Flat Roof Problems We Investigate in Menai Bridge
Common reasons for requesting flat-roof work include:
- Damp marks or dripping inside after rainfall
- Cracked, blistered or brittle roof coverings
- Loose roof edges, trims or flashing
- Failed joints around outlets, rooflights or walls
- Standing water that remains after rain
- Soft, swollen or deteriorating roof boards
- Old felt roofs that have been repaired several times
- A planned extension or garage needing a new roof
- Heat loss or condensation concerns above a lived-in room
Water does not always enter directly above the visible damp patch. It can travel beneath the waterproof layer before it reaches the ceiling, which is why a proper inspection is more useful than applying a quick surface patch.

Flat Roofing Systems for Menai Bridge Properties
EPDM Rubber Roofing
EPDM is a flexible rubber membrane often suited to garages, extensions and roof areas with a straightforward layout. It can cover a suitable roof with few seams and remains flexible through seasonal temperature changes.
Its reliability depends on sound decking, correct bonding and secure finishing at every edge, outlet, corner and wall junction.
GRP Fibreglass Roofing
GRP produces a seamless, rigid finish created on site using glass reinforcement, resin and a protective topcoat. It can be a good option for balconies, dormers, bay roofs and detailed roof areas.
The roof base must be dry and stable before GRP is installed. Correct preparation and suitable weather during installation are essential.
Reinforced Felt Roofing
Reinforced felt is a modern multi-layer system that can suit domestic and commercial roofs, especially where the roof has awkward shapes or several detailed junctions.
The preparation, laps, upstands, outlets and perimeter finish must all work as one complete roofing system.
Liquid-Applied Waterproofing
Liquid-applied systems can be particularly useful around complicated details, pipe penetrations, box gutters and roof surfaces where sheet materials would need many cuts. They can also be suitable for certain refurbishment projects after checking compatibility with the existing roof.
Liquid waterproofing is not simply paint. Cleaning, priming, reinforcement and correct application thickness determine whether it performs properly.
Warm Roof Insulation
A warm roof places rigid insulation above the structural deck and includes the layers needed to control moisture. It can improve thermal performance above extensions, bedrooms, offices and converted rooms.
The roof height, drainage, door thresholds, wall details and waterproof finish all need considering before insulation is added.
Flat Roofing for Menai Bridge Homes and Buildings
We carry out flat roofing work on:
- Rear, side and kitchen extensions
- Garage and outbuilding roofs
- Dormers, entrance canopies and bay roofs
- Balconies and accessible roof areas
- Holiday lets and rental properties
- Shops, offices and managed properties
- Workshops, storage buildings and commercial premises
A flat roof over a bedroom should not be treated in the same way as an unheated garage roof. The building use affects insulation, ventilation, vapour control and the final roof specification.
How We Plan Flat Roofing Work
Assessment: We inspect accessible surfaces, joints, outlets, drainage, roof edges, wall details and visible deck condition.
Recommendation: We set out whether repair, replacement or an insulated roof upgrade is appropriate, together with the reason.
Quotation: The agreed preparation, roofing system and work scope are confirmed in writing.
Preparation: Failed materials are removed where necessary, and the deck, falls, outlets and perimeter details are prepared.
Installation: The selected system is completed with compatible trims, flashings, outlets and reinforcement.
Completion: We check the finished roof details, leave the work area orderly and confirm the applicable guarantee terms.

“Had FlatRoof Masters out to look at the roof over our utility room in Menai Bridge. It had been dripping for ages whenever the wind and rain came in from the strait. They found a couple of issues that had been missed before, sorted it properly and did not leave any mess behind. Good lads and easy to deal with.”
Owain Thomas
“We were worried the roof over our rear extension would need replacing, but they were honest about it and said a repair was enough. The work was done a few days later, the price stayed as quoted and the leak has not come back. Would happily recommend them.”
Kirsty Lewis
“Really pleased with the new rubber roof FlatRoof Masters fitted on our garage. They removed the old covering, renewed the boards that needed doing and finished the edges neatly. It looks a hundred times better than it did before.”
David Morgan
“Phoned after noticing a wet patch in the kitchen ceiling. They came to inspect the flat roof, explained it in normal terms and gave us options instead of pressuring us. We went ahead with the replacement and the whole job was straightforward from beginning to end.”
