Roof Revival: Faster, Cleaner Roof Remediation for Your Next Job

Viking Roofspec’s Roof Revival systems go straight over the existing roof, so you can restore waterproofing and lift thermal performance without the strip-out, the skip bins, or the programme headaches.

By skipping full roof removal, Roof Revival helps you:

Get on and off site faster, with no tear-off stage to hold up the job
Cut back on noise, dust, and complaints from occupants and neighbours
Avoid the weather risk of an open, exposed roof during removal
Keep the building operating while you work, with no temporary relocations to manage
Reduce waste and disposal costs — over 90% of Viking materials can be used as overlay solutions

It’s a practical fit for jobs where downtime isn’t an option, including schools, hospitals, apartments, offices, and commercial premises. Roof Revival works over ageing flat and low-slope roofs, including bitumen, membrane, and metal substrates.

Every Roof Revival specification starts with a thorough site assessment by a Viking Roofspec representative so we can help determine the most appropriate solution tailored to your building’s specific performance requirements and to give you the technical support you need.

Talk to us about your next project and find out if the roof qualifies for revival instead of replacement.
