SIGnature Torch On Roofing System
Liquid Roofing Solutions with Sika Liquid Plastics
At DVC Commercial Roofing Contractors, we specialise in liquid roofing systems that provide durable, watertight, and low-maintenance solutions for commercial and residential projects. Recently, we completed two Sika Liquid Plastics balcony roof systems for an estate in Whitby, demonstrating our expertise in liquid applied roofing solutions that are both practical and long-lasting.
The client required a waterproof roof system capable of handling foot traffic. Our team installed a Sika Liquid seamless system incorporating a hard-wearing anti-slip topcoat, providing a 20-year warranty. The result combines excellent workmanship with a seamless, aesthetically pleasing finish, ensuring safety, durability, and peace of mind for building occupants.
Commercial Flat Roof Replacement with Signature Torch on System
At DVC Commercial Roofing, we specialise in commercial flat roof installations, repairs, and replacements across the United Kingdom. One of our notable projects involved a commercial flat roof survey and replacement using the Signature Torch On roofing system. This project highlights our commitment to high-quality workmanship, adherence to manufacturer specifications, and long-lasting roofing solutions for commercial properties.
Survey Findings: Why the Roof Needed Replacement
During the initial survey conducted by SIG, the existing flat roof was found to be defective and beyond its life expectancy. Key issues identified included:
- Saturated insulation deck compromising thermal performance
- Split and detached perimeter flashings
- Degraded roof membrane, at risk of leaks and water ingress
For commercial buildings, flat roof defects can lead to structural damage, increased energy costs, and safety hazards. Early intervention with a professional commercial roof inspection ensures timely replacement and minimises long-term costs.
Project Scope: How DVC Roofing Delivered the Solution
After being successful in the tender process, DVC Commercial Roofing commenced work on the site with a clear focus on quality, safety, and efficiency. The key stages of the commercial flat roof replacement included:
1. Stripping Defective Materials: All old roof membranes, insulation, and perimeter flashings were removed down to the metal profile sheet, ensuring a clean, sound base for the new roofing system.
2. Skylight Replacement: Old flat roof skylights were replaced with barrel-vaulted, insulated aluminium windows, improving both aesthetics and thermal performance.
3.Vapour Control Layer Installation: A new Vapour Control Layer (VCL) was fixed directly to the metal deck. The VCL prevents condensation and protects the insulation layers, ensuring the longevity of the roofing system.
4. Insulation Board Fixing: New 80mm flat roof insulation boards were adhered with Signature PU adhesive. Staggered joints were used, and no screws penetrated the VCL, maintaining the integrity of the vapor barrier.
5. Signature Torch On Membrane Application: The roofing finish consisted of a two-layer Signature Torch On system:
- Signature 25 Underlay: Provides a durable base layer for torch-on roofing
- Signature Torch On Cap Sheet: Offers superior waterproofing and UV protection
6. Perimeter and Edge Details: All edges were finished with Signature GRP trims for clean lines, ensuring both functionality and aesthetic appeal from ground level.
Throughout the project, workmanship was closely monitored by a Signature Specification Engineer, ensuring full compliance with manufacturer standards and maintaining the highest quality.
Warranty and Client Assurance
Upon completion, all project documentation, including inspection reports and installation details, were collated and handed over to the client. This ensures the client has full verification for the 25-year Signature Torch On system warranty, giving confidence in the durability and performance of their commercial flat roof.
