Reliable Commercial Roof Over in Portsmouth
A failing commercial or industrial roof - one that is leaking, fragile, or contains asbestos - presents a major operational challenge. Traditional strip-and-rebuild projects are expensive, messy, and force you to shut down operations, exposing your assets to the elements.
The Roof Over System (Overlay System) is the modern solution for immediate and long-term roof performance. Finn Industrial Roofing installs a new, fully insulated, and robust outer shell directly over your existing structure. This provides a guaranteed, weather-tight barrier and a dramatic thermal upgrade with minimal interruption to your business.

Our Expert Roof Over Installation Process
Our experienced team manages the entire Over Roofing project, adhering to the highest standards of safety and quality from initial assessment to final sign-off.
-
Feasibility Survey & Design: A structural engineer performs a survey to confirm the existing purlins can safely carry the minimal additional load. We then design a custom, lightweight spacer system and select the appropriate high-performance sheeting (e.g., steel or composite).
-
Spacer System Installation: A bespoke, lightweight framework is installed above the existing roof to create a void, ensuring proper air circulation and providing a strong, flat base for the new materials.
-
Insulation Laying: New, high-grade insulation is laid within the void, transforming the thermal performance of your entire facility.
-
New Roof Installation: High-quality, weather-tight profile sheets are secured to the spacer system, complete with new flashings, gutters, and rooflights, completing the high-performance overlay.
