FLEXITEC resinNew roof protection.
Another way to refurbish.
A flexible liquid system that follows the shape of your roof.
FLEXITEC by RESTEC combines liquid resin with fibreglass reinforcement to create a seamless waterproof covering. It can be specified for new roofs or as an overlay on suitable existing materials, including felt, asphalt and GRP.
- Continuous coverage across the roof and around detailed areas
- Liquid application around edges, outlets and rooflights
- An overlay option that can reduce stripping work where the existing roof is suitable
Is an overlay right for your roof?
We assess the existing covering, deck, adhesion and drainage first. An overlay must be based on a suitable roof; it is not a substitute for addressing defects underneath.
Torch-on felt being laid.Felt roofing for
garages & extensions.
Three-layer torch-on and other built-up felt options, clearly specified.
Built-up felt roofing uses layers of bituminous membrane to form the roof covering. The chosen products, roof construction and installation method work together as a complete system.
Three-layer torch-on felt
A specified three-layer build-up, finished with a protective cap sheet. We consider the deck, roof edges and adjoining construction, including details that require a flame-free approach.
Other built-up felt options
We can also discuss alternative felt specifications for garages and extensions. The appropriate number of layers and method of fixing depend on the selected system and the roof beneath it.
Know exactly what you are comparing
Your quotation will set out the proposed membranes, layers and installation method, alongside any deck repairs, insulation or drainage work included.
EPDM membraneA flexible covering.
A considered fit.
A rubber membrane for suitable extensions, garages and other flat roofs.
EPDM is a synthetic rubber roofing membrane. Supplied in large sheets, it can cover many smaller roofs with few or no joints across the main surface. The roof’s size and layout determine the membrane arrangement.
- A flexible membrane that accommodates movement
- Large sheets that reduce joints across the main roof area
- A cold-applied system using compatible adhesives and detailing products
The perimeter matters as much as the surface
We assess the deck, drainage and roof dimensions, then plan the edges, wall junctions, outlets and any rooflights. Compatible trims and seals complete the chosen system.
Fibreglass matA neat finish,
built from the deck up.
A fibreglass roofing system for new decks and suitable roof replacements.
GRP combines fibreglass reinforcement and roofing resin over a suitable prepared deck. A finishing topcoat and formed edge trims complete the surface and give the roof a clean, continuous appearance.
- A continuous resin and fibreglass laminate
- Formed trims for neat roof edges and junctions
- A specified deck, reinforcement and topcoat working together
A sound deck comes first
We consider deck condition, roof movement, drainage and installation conditions. If the roof is being stripped, the quotation should make any deck replacement and associated work clear before installation begins.
Not sure which system
your roof needs?
You do not need to choose a material before getting in touch. Tell us about the building and what you have noticed. We’ll discuss whether a repair, a suitable overlay or a replacement is the appropriate next step.
- The existing roof
The condition of the covering and deck, and whether any defects need attention.
- Drainage & details
Where water runs, roof edges, wall junctions, outlets and rooflights.
- The space beneath
How the building is used and the deck, insulation and ventilation within the proposed roof construction.
Understand what
your quotation covers.
The size of the roof is one factor, but the condition of the deck can make a substantial difference to the work. Outlets, rooflights and changes of level add details that a plain rectangular roof may not have. Access over a conservatory or through a restricted passage can also affect the arrangements.
Your quotation should make clear whether it covers a local repair, a new covering or a more extensive rebuild of the roof layers. We discuss visible findings and any limitations of the assessment so that a price for a surface repair is not confused with the cost of a complete replacement.
What belongs in a flat roofing quotation
- Repair area or full replacement boundary
- Existing covering removal or assessed overlay approach
- Deck condition and any replacement allowance
- Named covering system, trims and wall junctions
- Falls, outlets, rooflights and rainwater connections
- Insulation, access, waste removal and exclusions
Tell us about the roof
Start with your contact details, postcode and the work you have in mind. You do not need to diagnose a problem before getting in touch.
Assess the proposed work
We’ll discuss the property and arrange a visit where needed. Access, materials and the condition of the existing roof help define the scope.
Review & agree the details
Read the written quotation and ask about anything that is unclear. The work, arrangements and any agreed changes should be confirmed before proceeding.
Find flat roofs near you.
From our Reading base, we cover towns across Berkshire, Hampshire, Oxfordshire, Buckinghamshire and Surrey. Choose your area below, or send your postcode to confirm availability for your property.
Let us know whether the roof is over a garage, extension, porch or other space, and approximately when it was last worked on if known. Mention rooflights, any equipment on the roof and whether the leak changes during heavy or wind-driven rain.
Access is specific to each property. Please mention shared drives, limited parking, neighbouring buildings or an extension beneath the roof. These details help us plan an assessment and allow for the right access in your quotation.

Flat Roofs:
before you decide.
These answers are a starting point. The right approach depends on your property and the findings of an assessment.
Ask us about your roof →Can my flat roof be repaired instead of replaced?
A local defect may be repairable if the surrounding system is in suitable condition. Widespread deterioration, a damaged deck or recurring problems at several points can call for a broader scope. We discuss the findings before recommending the next step.
Can a new covering go over the existing one?
Only after checking compatibility, condition and moisture concerns. An overlay can conceal problems if the existing layers are unsuitable. The quotation should say whether removal is needed and what assumptions have been made about the deck.
Does standing water mean the whole roof has failed?
Not necessarily, but persistent ponding deserves assessment. Drainage points, debris, falls and the roof’s condition should be considered together. A photograph taken safely from an accessible window can help explain what you have noticed.
Can you quote for a roof with a lantern or rooflight?
Yes, include it in your enquiry. The surrounding upstand and waterproofing junction need to be part of the scope. Tell us whether the glazing is staying, being replaced or being added as part of other work.
Can I use the roof as a terrace afterwards?
A normal roof covering should not be assumed to be a usable terrace. Regular access, loading, protection and guarding require a suitable design. Please tell us about any proposed change of use before a roofing specification is prepared.
How do I look after a replacement flat roof?
Ask for the care guidance for the system specified. Keep an eye on drainage from a safe position and arrange appropriate clearing or inspection when needed. Avoid placing items or walking on the roof unless it has been designed for that use.
