Designing Durable Warm Roof Systems with Allco - A QS Perspective
Warm roof systems are increasingly being specified across New Zealand for their thermal efficiency and long-term durability. From a Quantity Surveying (QS) perspective, leveraging supplier - backed systems like Allco’s ensures we work with well-documented solutions that support accurate planning, takeoffs, and project delivery.

Why Warm Roof Systems Matter
Warm roof assemblies improve performance by keeping insulation above the structure, reducing thermal bridging, and protecting the building envelope. This design choice is becoming more common in both commercial and residential projects, where lifecycle value is as important as upfront cost.
How Allco Supports Project Accuracy
Allco provides comprehensive design details, CAD drawings, and technical support. For QS professionals, this means reduced ambiguity in takeoffs and clearer scope definitions, minimising costly variations during construction. The alignment between Allco’s design resources and site execution is a key advantage when working on projects that demand both performance and precision.
QS Insights in Practice
When we prepare waterproofing takeoffs and BOQs, having access to Allco’s warm roof details gives us a stronger base for quantification. This ensures that system-specific nuances — such as tapered insulation or drainage detailing — are accounted for early in the process, leading to more reliable project estimates.
Bring QS Precision to Your Next Project
At Aquosync, we specialise in translating supplier data — like Allco’s — into clear, project-ready takeoffs. That means fewer changes, fewer delays, and more confident quoting.
