Our Installation Process
Process-01: Free Consultation and Planning
Our project begins with an in-depth consultation, assessing your roof, substrate, property needs, and budget. Our roofing contractors will help you understand the best options available, from materials to design, so that you can make an informed decision.
Process-02: Proper Material Selection
We provide a wide range of premium flat roofing materials, including Felt and GRP. Our expert team explains the benefits of each type of material, from cost-effectiveness to maintenance requirements, ensuring you find the right material match for your roof.
Felt, or modified bitumen, roofing typically uses a three-layer system, often applied with a torch for a waterproof seal.
- Surface Preparation: The existing surface must be cleaned, dry, and free of debris.
- Venting Base Sheet: A layer of venting base sheet is applied to prevent moisture buildup.
- Reinforced Felt Underlay: A reinforced felt layer is added for extra protection.
- Mineral Cap Sheet: A final layer, often a mineral cap sheet, provides UV and physical damage resistance.
- Application: The felt is often adhered by torch-on application, using heat to melt the bitumen and bond it to the roof.
GRP roofing creates a durable, seamless, and long-lasting waterproof membrane.
- OSB Deck Installation:
OSB (Oriented Strand Board) boards are installed to create a flat, suitable roof deck.
- Edge Trims:
GRP edge trims are installed to create a border around the roof area.
- Resin Application:
A mixture of resin and a catalyst is applied to the roof surface and the bandage on the trims.
- Fibreglass Laminating:
Fibreglass matting is then cut and laid over the resin, which is “wet out” using a roller to saturate the glass strands.
- Topcoat:A protective topcoat is applied once the laminate is no longer sticky, typically within 24 hours.
Process-05: Final Inspection and Aftercare
After complete installation, we conduct a full roof inspection to confirm quality work and roof durability. You’ll receive a full 15-year guarantee, assuring you of the quality and longevity of our work, and you will also get aftercare advice.
