Industrial roof refurbishment and photovoltaic systems: asbestos removal and installation process
For many Italian companies, the industrial warehouse roof represents a paradox: an underutilized asset that hides a critical liability. The presence of old asbestos-cement roofing, commonly known as eternit, is not only an environmental risk but also a structural limitation that prevents access to the benefits of modern industrial photovoltaic systems.
Turning the obligation of asbestos removal into an energy efficiency project allows companies to convert a fixed cost into a revenue-generating asset. Addressing asbestos removal and photovoltaic installation through an integrated approach makes it possible to optimize costs and upgrade the building in a single intervention.

Why asbestos removal is a prerequisite for solar installation
A common question is whether solar panels can be installed directly on existing asbestos-cement sheets. Although encapsulation techniques exist, in engineering and industrial practice, complete asbestos removal is the preferred solution.
Installing photovoltaic systems on asbestos roofing would introduce several critical issues:
- Structural integrity: old sheets are not designed to withstand the static and dynamic loads of a modern PV system;
- Regulatory safety: installation activities may interfere with asbestos-containing materials, requiring strict safety protocols under Italian Legislative Decree 81/2008;
- Maintainability: any future roof intervention would become a highly specialized and costly operation.
Preventive removal therefore creates a solid technical and regulatory foundation for an energy investment designed to last throughout the entire lifecycle of the system, ensuring a compliant and durable structure for the photovoltaic modules.
The operational process: from ASL documentation to grid connection
The combination of photovoltaic installation and asbestos removal on industrial buildings requires coordinated management of hazardous waste and electrical infrastructure. Relying on a single EPC contractor allows centralization of all critical phases:
- ASL Work Plan: preparation and submission of the work plan to the competent supervisory authority in accordance with Article 256 of Legislative Decree 81/08;
- Removal and encapsulation: site operations managed by certified companies that treat asbestos sheets to prevent fiber dispersion;
- Transport and Waste Identification Form (FIR): transfer to authorized landfills and issuance of the official waste identification document, the only legal proof of proper disposal;
- New roofing and installation: installation of new metal sheets or insulated sandwich panels, followed by mounting of photovoltaic modules.
2026 Incentives: opportunities for businesses
The framework for industrial roof refurbishment combined with photovoltaic systems in 2026 requires an up-to-date assessment of available incentives:
- Agro-industrial sector: the Agrisolar Facility remains one of the most solid measures for companies installing PV systems after asbestos removal on agricultural, livestock, and agro-industrial buildings;
- Industrial sector: manufacturing companies should evaluate tools such as the Nuova Sabatini, as well as regional incentives focused on environmental protection and energy efficiency;
- Site efficiency: beyond direct incentives, combining both activities significantly reduces logistics and safety costs, avoiding duplication of scaffolding and site setup expenses.
Construction timeline: Southenergy operational benchmark
Based on our experience in managing complex redevelopment projects, timelines depend on surface area and accessibility. On average, our operational benchmarks indicate:
- Administrative phase (ASL/permits): often the longest stage, depending on local authority approval times;
- Execution phase: for a medium-sized warehouse (approx. 1,000 sqm), asbestos removal and photovoltaic installation proceed quickly, with installation following immediately after roof refurbishment to minimize disruption to production activities.
FAQ – Frequently Asked Questions
In professional practice, this is not recommended and is technically complex. Complete removal eliminates the risk of fiber dispersion at the root and allows installation on a new, safe, and long-lasting structure, ensuring the roof’s integrity for the entire lifespan of the photovoltaic system.
In 2026, measures such as Agrisolar provide strong support for those remediating asbestos in the agro-industrial sectors. For general manufacturing and logistics industry, access to schemes like Nuova Sabatini or specific regional sustainability incentives in Puglia should be carefully evaluated.
The total cost depends on the surface area and the type of new industrial roofing system selected. However, integrating both activities into a single project reduces fixed safety and logistics costs (such as crane rental and scaffolding), significantly improving the overall ROI of the investment.
A General Contractor oversees the entire administrative and operational process: from ASL work plan submission to safety coordination and FIR (Waste Identification Form) delivery, relieving the company and the Safety Manager of all operational responsibilities related to disposal.
