Repairs and Refurbishment of Asphalt Roofs
Mastic asphalt is a traditional flat roofing material laid hot in layers to form a dense, seamless waterproof surface. It is very durable and is still found on many older commercial buildings, blocks of flats, balconies and period properties across Bristol and Bath.
We repair and refurbish mastic asphalt roofing in Bristol and Bath, from cracked and blistered areas to full overlays with modern compatible systems where the asphalt has reached the end of its life.
Where Mastic Asphalt Roofing Works Best
Mastic Asphalt Roofing is a good choice for:
- Older commercial and public buildings
- Blocks of flats and maisonettes
- Balconies, walkways and roof terraces
- Period buildings with traditional flat roofs
- Roofs carrying regular foot traffic
- Parapet and box gutters
Common problems with asphalt roofs include cracking from movement and cold, blistering from trapped moisture and failed upstands at walls and parapets. Many can be repaired. Where the asphalt is widely failing, overlaying with a liquid system or single ply membrane is often more cost-effective than full removal.
Expert Advice
Why Asphalt Roofs Crack and Blister
Mastic asphalt is a dense, rigid material. Over time, movement in the building, temperature changes and ageing can cause cracking, especially at upstands and junctions. Blisters form when moisture trapped beneath the asphalt expands in warm weather. Both can usually be repaired locally if the rest of the roof is sound.
Protecting Asphalt
Solar reflective paint or chippings reduce heat build-up and slow the ageing of asphalt. Keeping outlets clear and repairing small defects promptly can add many years to an asphalt roof.
Refurbishment Options
Where repairs are no longer practical, a liquid or single ply overlay can often be applied over the existing asphalt, avoiding the cost and disruption of full removal.
Installation and Repair
Our approach to asphalt roofs:
- Survey the roof to find cracks, blisters and failed upstands.
- Repair localised damage with compatible materials.
- Where needed, overlay with a suitable modern system.
- Check outlets and upstands, then hand over with photos.
