The refurbishment of old existing bitumen roofs is by far the largest part of all roof reconstructions. Sika has a full range of systems ideally suiting these roof refurbishment jobs.
Advantages of Sika Refurbishment System
Compared to traditional bitumen reroofing, all of the Sika refurbishment systems have many advantages:
- Longer life-expectancy and guarantees
- Availability of light colored reflective membranes which reflect heat and light, thus saving energy and costs
- Lower additional load on the structure– the additional weight of Sika single ply or liquid applied waterproofing is
- much lower than several layers of bitumen that would be required for the job
- Considerably higher flexibility and elasticity in cold temperatures
- No risk of fires during application due to the totally flame free installation methods
- Increased fire resistance of the waterproofing system itself
