Which flat roofs are common in Angus?
Flat roofs in Angus sit on low-rise post-war blocks of flats, bungalows with flat-roofed side extensions and dormers and 1960s and 1970s link-detached houses with flat-roofed garages and porches. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write. Approximate 1991–2020 regional averages based on Met Office data.
Building standards in Scotland
In Scotland a building warrant is usually needed for alterations, structural work and new roofs; like-for-like repairs to a covering can be exempt. Section 6 of the technical handbooks sets a domestic roof benchmark of 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. In Angus the application goes to Angus Council (building standards). More on the rules.
How long does mastic asphalt last, and what guarantees are available?
Mastic asphalt is one of the longest-lasting flat roof systems, typically giving 30 to 60 years with good specification and maintenance. Many older asphalt roofs are still watertight decades after they were laid.
Age does show eventually. Common signs include crazing and cracking from sun exposure, blisters where moisture has been trapped beneath, splits at skirtings where the building has moved, and ponding where the deck has settled. Regular maintenance, such as renewing solar reflective paint, keeping outlets clear and repairing cracks early, makes a real difference to life.
Material and system guarantees are available on some specified asphalt systems, and we register them for you where the system allows. Every re-roof carries our written workmanship guarantee, with the length set out in the quote, and insurance-backed options can be discussed. Our lifespan guide compares asphalt with the other systems.

Can I repair a mastic asphalt roof myself?
Not properly. Lasting asphalt repairs use fresh hot asphalt, which needs specialist equipment, training and hot-works control. Cold-applied sealants can hold a small leak for a short time, but they are a stopgap until a specialist repair.
Why is my asphalt roof cracking?
Asphalt typically cracks as it ages and becomes brittle from sun exposure, or where the building moves at skirtings and junctions. A solar reflective paint and early repairs help slow it down.
Is mastic asphalt suitable for a balcony or terrace?
Yes, asphalt is traditionally used on terraces and walkways because it takes foot traffic well, often with paving on top. A new balcony or terrace generally needs planning permission, so check before converting a roof.
