It is a cost-effective alternative to full replacement. City Building and Roofing Ltd carry out roof refurbishment across London and Surrey, starting with a free inspection and honest advice on whether refurbishment or renewal is right for your roof.

Roof Refurbishment Services We Carry Out
Moss & Algae Removal
Moss and algae growing on roof tiles trap moisture and cause premature deterioration of tiles and mortar. We safely remove moss and treat the roof surface to prevent regrowth.
Tile Replacement & Re-bedding
Displaced, cracked or broken tiles are replaced with matching tiles where possible. We re-bed and re-point ridge tiles and hip tiles to restore a watertight roof.
Roof Cleaning & Treatment
We professionally clean the entire roof surface, removing years of dirt, lichen and biological growth — then apply a biocide treatment and sealant to protect the surface.
Pointing & Repointing
Deteriorated mortar around ridge tiles, hip tiles and verge details is raked out and replaced with fresh mortar — one of the most effective ways to prevent leaks.
Flat Roof Refurbishment
We clean, repair and reseal existing flat roofs — including felt, GRP and EPDM — extending the life of the roof by many years without the cost of full replacement.
Flashing Replacement
Deteriorated lead or aluminium flashings around chimneys, dormers and valleys are replaced — one of the most common causes of leaks in London's older properties.
Why Refurbish Rather Than Replace?
- A fraction of the cost of a full roof replacement
- Extends the life of your existing roof by 10–20 years with the right treatment
- Less disruption than a full re-roof — often completed in 1–3 days
- Restores the appearance of your roof and property
- Identifies and fixes small issues before they become serious leaks
- Ideal for roofs with sound underlying structure that just needs attention

Frequently Asked Questions
How long does a roof repair take?
Most standard roof repairs in London can be completed within a day. Larger repairs or full roof replacements may take 2–5 days depending on the size and condition of the roof. We always give you a realistic timeline upfront.
How do I know if my roof needs repairing or replacing?
Signs your roof may need attention include missing or damaged tiles, visible daylight through the roof, damp patches on ceilings, blocked gutters, crumbling pointing around chimneys, or a roof over 25 years old. We offer a free inspection to advise you properly.
What materials do you use for new roofs?
We use only quality, long-lasting materials sourced from reputable UK manufacturers. For pitched roofs we commonly use concrete and clay tiles or natural slate. For flat roofs we install GRP fibreglass, EPDM rubber and three-layer felt systems.
How long does a GRP fibreglass flat roof last?
A properly installed GRP fibreglass flat roof should last 25 years or more. We back our GRP installations with a 25-year manufacturer warranty, plus our own workmanship guarantee.
