Our Capabilities
Dedicated Pitch & Flat Roofing Solutions
Led by Jimmy Frankham, High class roofing diagnoses and repairs all forms of residential and light commercial roofing. We trace water ingress back to its true origin rather than covering up structural symptoms.
Roof Leak & Storm Damage Repairs
We trace water ingress back to its true source—whether that is a slipped slate, failed valley leadwork, or perishing mortar along the ridge. In heavy storms, we make the building watertight before executing permanent timber, membrane, and tile reinstatements.
- Emergency tarpaulin weatherproofing
- Internal leak path detection
- BS 5534 batten & membrane patching
New Roof Installation & Replacement
Complete strip and re-covering service for aging roofs across Slough, Windsor, and Maidenhead. We install modern high-performance vapour-permeable membranes, treated structural counter-battens, and quality clay or concrete tile systems built to endure local weather.
- Complete tear-off down to rafters
- Part L thermal insulation upgrades
- Interlocking concrete & clay profiles
Flat Roof Repairs, EPDM & GRP
Replace failing, blistered bitumen felt with hard-wearing single-ply EPDM rubber or seamless GRP fibreglass. Ideal for domestic kitchen extensions, dormer flat tops, and garages across Maidenhead and Slough prone to ponding water.
- Cold-applied jointless GRP resin systems
- Single-sheet EPDM rubber membranes
- OSB3 structural deck renewal & falls
Slate & Tiled Roof Repairs
Precise repair for natural Welsh slate, hand-made clay plain tiles, and modern interlocking concrete pantiles. We replace cracked units, refit rusted nail fixings with copper nails, and resolve dormer interface failures without disturbing sound surrounding courses.

- Plain clay Rosemary & peg tile matching
- Concrete tile storm clipping (BS 5534)
Chimneys, Leadwork & Valleys

- Weather-struck chimney mortar repointing
- Lead apron, cover & step flashing renewal
- Valley gutter leadwork replacements
Ridge Tiles, Fascias & Guttering
Prevent roof timber rot and foundation damp. We re-bed loose sand-and-cement ridge tiles, convert storm-damaged ridges to ventilated dry-fix systems, and replace sagging rainwater goods with high-capacity deep-flow UPVC gutters and rot-proof fascias.
- Traditional mortar ridge bedding & pointing
- Dry ridge and dry verge mechanical upgrades
- Deep-flow UPVC guttering & downpipes
Tailored to Thames Valley Architecture & Regulations
Roofing in Berkshire requires genuine familiarity with distinct regional building periods. The 1930s semi-detached homes of Slough require durable interlocking concrete tiles and modern dry-verge verge clips to withstand open valley wind loading.
Conversely, properties situated in conservation areas—such as the Datchet Village Green, the Royal Borough of Windsor and Maidenhead (RBWM) heritage zones, or Uxbridge Old Town—frequently require strict adherence to Article 4 directives. We supply matching natural Welsh slate, hand-made clay plain tiles, and traditional milled Code 4 lead details to ensure compliance without compromising weather resistance.

Technical Guidance
Frequently Asked Questions
Straight answers regarding roof repairs, materials, and regulations in our area.
How do I know if my roof leak is an emergency?
If rainwater is actively pouring through ceilings, pooling near light fixtures, or causing ceiling plasterboards to bow under weight, it requires immediate attention. Slow damp patches or minor loft staining can typically be inspected during regular daylight hours, but active water ingress risks electrical failure and rapid timber rot. Call our 24/7 line on 01256 639416 for urgent assistance.
Do I need planning permission to repair or replace my roof in Windsor or Datchet?
Most re-roofing projects fall under Permitted Development rights, provided the roof shape is not significantly altered. However, properties located within designated Conservation Areas (such as Windsor or Datchet Village Green) or listed buildings frequently have Article 4 directions requiring like-for-like materials (such as matching natural slate or clay plain tiles). We ensure material choices align with Royal Borough of Windsor and Maidenhead requirements.
When is it necessary to upgrade roof insulation during a re-roof?
Under Building Regulations Part L, if you replace more than 50% of the pitched or flat roof covering on a domestic property, you are legally required to upgrade the thermal efficiency to meet current U-value standards, provided this is technically and economically feasible. We will advise you on the correct rigid PIR board or mineral wool installation during our initial site inspection.
What is the difference between EPDM rubber and GRP fibreglass for flat roofs?
EPDM is an elastomeric synthetic rubber installed in large continuous sheets with high UV resistance and excellent flexibility to accommodate seasonal building movement. GRP fibreglass is a liquid-applied resin system reinforced with chopped strand matting that cures into a rigid, totally seamless finish. GRP is particularly suited to complex roof shapes, parapets, and light foot traffic, while EPDM is ideal for larger residential extensions and garages.
Can you repair a leaking valley gutter without replacing the entire roof?
Yes. Valleys represent a specific junction where two pitched roof slopes meet. We can lift the surrounding cut tiles, inspect and replace rotted valley boards, install new Code 4 or Code 5 milled lead sheets or pre-formed GRP valley troughs, and neatly re-cut and re-lay the existing tiles without stripping the remainder of the roof slope.
What causes ridge tiles to blow off during Thames Valley storms?
Traditional ridge tiles bedded with standard sand-and-cement mortar degrade over time due to seasonal freeze-thaw cycles and structural vibration. Once the mortar bond cracks, strong wind gusts enter underneath, creating aerodynamic uplift that lifts tiles away. We re-bed ridge tiles using polymer-fortified mortar or convert your roofline to a mechanically fastened dry-ridge system that eliminates mortar failure entirely.
