uPVC Fascias, Soffits and Cladding

We replace tired timber with low maintenance uPVC systems that protect rafter ends and improve airflow. Colour matched fascias and soffits, bird guards where needed, and tidy drip edges. Any soft or decayed wood is replaced so the new system lasts.
Enquire Now

Guttering Services High Wycombe

We install and repair uPVC and aluminium gutters and downpipes. Alignment and joints are tested with water so rain drains away from brickwork and foundations. We also clear and flush existing systems and can fit guards to reduce blockages.

Chimney Repairs and Leadwork

Chimneys are common leak points. We repoint, renew stepped and tray flashings, form back gutters and soakers, and cap unused pots to reduce water ingress while maintaining ventilation. Redundant stacks can be safely removed on request.
Enquire Now

Spray Foam Removal

Old spray foam can trap moisture and hide defects. We carefully remove foam to restore breathability, assess timbers and replace any affected sections. A breathable underlay can then be installed to keep the loft dry and compliant with modern standards.
Enquire Now

Moss Removal By Hand

We clean roofs by hand to protect tiles, then apply a biocide treatment to slow regrowth. Cleaning is only carried out once faults are repaired, so appearance improvements do not mask issues that need attention.

Local clients recommend us for prompt responses, honest guidance and neat finishes. Ask to see recent before and after photos from HP14 and surrounding areas, plus references where available.

Removal of Chimney stack, replacement of roof underlay, guttering and flat roof repair. - Mitchell from Alliance Roofing & Building was the only builder, of many that I had contacted, that climbed a ladder to inspect my flat-roof and to climb into my loft-space to inspect the main roof from the inside. After an extensive review of my property and discussing my options, he emailed me his quotation on the same day. Booking in dates for Alliance & Roofing to commence work was quick and effortless. They arrived on time, completed the work as planned to a professional standard. Provided Photos of work carried out at all stages. I highly recommend Alliance Roofing & Building.
