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.
Mastic Asphalt Roofing is a good choice for:
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.
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.
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.
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.

A well laid asphalt roof can last for decades, especially when protected with solar reflective paint or chippings.
Yes. Localised cracks and blisters can be cut out and repaired with compatible materials.
Where traditional asphalt is required, for example on some period or listed buildings, it can be specified. For most refurbishments, a modern overlay is more practical.
It depends on the extent of damage and access.
Asphalt roofs often have plenty of life left in them. We repair what can be repaired and only recommend overlay or replacement when it really makes sense.
