Specify the complete flat roof system
A commercial flat roof refurbishment needs to account for the deck, vapour control, insulation, waterproofing, drainage and every junction. The existing construction and condition should guide the specification.
KRP Roofing provides commercial flat roofing services across Hampshire and the South of England. Discuss your proposed refurbishment or replacement, whether you already have a system specification or need to establish the next stage of assessment.
Key decisions before the work begins
- Whether the existing construction can be retained
- Moisture and substrate condition, including any need for opening-up
- Waterproofing and insulation specification
- Upstands, outlets, penetrations and rooflights
- Site access, temporary protection and working arrangements
Project questions
Which waterproofing system should be specified?
The appropriate system depends on the substrate, roof geometry, use, condition and performance requirements. Compare suitable specifications and their installation and maintenance requirements.
Can insulation be upgraded during refurbishment?
It can be considered within the scope. The design must account for the existing construction, condensation risk, heights at junctions and applicable performance requirements.
Are warranties the same for every system?
No. Provider, scope, duration, exclusions and maintenance obligations vary. Confirm the applicable terms for the proposed specification and installation.
