Prime contractors face many challenges in flat roof construction. In this article, we discuss some of the common flat roofing challenges and how our holistic approach, working with trusted manufacturers, can help prime contractors overcome the challenges.
1. Inappropriate specifications
One common problem with flat roofs is incorrect product or system specifications, whether by the architectural practitioner or elsewhere on the design team. A variety of problems can occur if a system or product is not suitable for the application. Additionally, some manufacturers may sell systems that are available to them rather than systems that fit specific project requirements.
SIG’s design and technology is product agnostic and compatible with flat roof systems from a wide range of major flat roof manufacturers. These systems include single ply, hot melt, built-up roofing felts, liquid, and rigid metal solutions. We handle everything from design to supply of green roofs, blue roofs, slates, tiles, etc. This allows you to choose the most appropriate system for your requirements, regardless of manufacturer preferences.
2. Not enough detail
When a prime contractor relies on a manufacturer to design a flat roof, there is a risk that the manufacturer will design it for its own system rather than the project. This can be particularly problematic at interfaces between product types, where manufacturers simply may not have the necessary expertise. What the main contractor really needs is a designer who will work with the architect and other suppliers to design a solution that works on all fronts, with appropriate interface details that do not compromise the integrity of the roof.
We have our own in-house design team and work with architects to identify areas that need to be addressed before work begins on site. This is backed by our own PI insurance and we also provide a collateral guarantee for the designs provided. A can-do attitude gives the prime contractor peace of mind that a team of experts is working towards his one goal.
3. Lack of understanding of build programs
Roofing works usually form part of the critical path of a building program. However, installed flat roofs may also provide useful or required space for contractors. As a result, the specified solution must allow the main contractor to utilize the roof space without risk of damage to the installed roof.
SIG Design and Technology’s partnership products are perfect for this situation. We specify a system on your behalf that delivers a waterproof envelope, is easy to manage on site, and provides a protected finished roofing solution.
and executes as expected. We also offer on-site support from our field technicians. Our construction reports can be used to monitor successful roofing contractor performance and snags.
4. Follow-on trade
The installed roof is a useful space on site, but this also affects subsequent transactions. The roof system must meet the project requirements, but it must also be robust enough to withstand field conditions rather than test conditions. A good partner will work with the main contractor to understand the project program and support the correct sequence of roofing work to avoid future problems.
Because we understand what each roof type and system can do in the field and are involved in the design, we can provide advice and help you avoid many roofing transactions. can. We also provide toolbox talks to field teams to help them manage what they can and can’t do, ensuring a confident and high-performing team.
5. Lack of communication
Good communication, including between prime contractors, suppliers, and roofing contractors, is essential for a smooth program. Without a tailored approach to material supply and specific site requirements, work can be delayed and programs delayed. In the worst-case scenario, roofing contractors may be under pressure to respond by using untrained or subcontracted labor, with all the risks that come with it.
Because we take a partnership approach, SIG Design and Technology can support our customers from the tender process through to pre-start meetings on site. This will help you identify potential problems and how to avoid them. We also act as a liaison between you and the right roofing contractor based on your project needs, facilitating communication and ensuring the job progresses as planned.
6. Value engineering challenges
Value engineering plays a role in the construction process, but always going for the cheapest system without understanding the implications of these decisions can lead to legacy issues and defects in flat roofs.
SIG Design and Technology offers competitive prices and accepts that these prices are market tested to ensure competitiveness. This gives you cost certainty while remaining proactive during the bidding stage. When you combine our expertise with the benefits of a collaborative partnership approach, you and your clients get the best of both worlds.
7. Maintenance challenges
As roof systems become more complex, the risk of misunderstanding the maintenance requirements for each specified system increases. This will ultimately lead to voiding of the warranty and the burden will fall entirely on the prime contractor.
SIG Design and Technology coordinates warranty and maintenance requirements and documentation to help you meet your responsibilities. As your supply chain partner, we ensure that the process of providing this important document to your clients is simple and smooth.
