Qualifications and training

Some employers may want you to have GCSEs (or equivalent such as the Welsh Baccalaureate) in English, Maths and Design and Technology or the BTEC Certificate to qualify. 

Some experience of working on a building site can be useful in getting a foot in the door, but it’s not essential. If you haven’t worked in construction, think about being a labourer to start with. Then your boss may train you in asphalting.

An apprenticeship is a good way to start your career as a mastic asphalter. Entry to an apprenticeship scheme usually involves taking a selection test. As an apprentice, you study for NVQ Level 2 and 3. To find an apprenticeship visit the Government's website, or Careers Wales.

The Institute of Roofing offers its own qualifications, and will be able to offer you help and advice. 

With on the job and off the job training, you would work towards a Scottish Vocational Qualification (SVQ) in Roofing Occupations (Construction) at Levels 2 and 3 and Applied Waterproof Membranes (Construction) (Built Up Bituminous Roofing) Level 2 (SCQF level 5).


  • A newly trained mastic asphalter can earn in the region of £17,000 - £20,000
  • Trained with experience mastic asphalters can earn in the region of £20,000 -£35,000.00
  • Self employed mastic asphalters can set their own rates

Salaries will vary depending on location / employer.
