Leaks in commercial real estate can confuse tenants and owners, leading to costly damage. The lease agreement determines who handles the leak, but general guidelines exist. Unchecked leaks increase the likelihood of recurring issues, regardless of the source, such as poor drainage, tenant installations, or flashing failures. In this article, we will discuss what hybrid roofing systems are and the types of roofing systems you need to opt for.

Meaning of a hybrid roofing system

A hybrid flat roof waterproofing system uses multiple materials to overcome construction project obstacles. For example, on a bituminous felt roof, PMMA liquid waterproofing resin expedites penetrations and intricate details, resulting in a durable, seamless, and watertight finish.

Types of Hybrid Roofing Systems

1. Polyiso hybrid systems and EPS taper systems

Insulfoam's tapered EPS insulation and Polyiso flat board insulation can be combined to create a hybrid roof insulation system, saving time and money. This system, available up to 40" thick, allows for positive drainage and streamlines job site processes, benefiting assistive building professionals.

2. Polyiso over-top with EPS flute-fill for metal retrofit roofs

EPS and polyiso are ideal for metal retrofit roofs, with EPS as flute fill and polyiso over the top. Precision-cutting of EPS and polyiso can save time on construction sites by eliminating the need for field insulation cutting. Carlisle Syntec Systems claims that polyiso, installed over EPS flute fill, offers energy-efficient solutions for buildings, with significant energy savings and a return on investment, combined with EPS insulation's airtight properties.

3. Systems of single-ply roofing

Single Ply Roofing systems use EPDM, PVC, and TPO membranes, thermoset or thermoplastic materials resistant to weathering. They can be installed in all four seasons and secured through ballast, adhesion, or mechanical fastening.

4. Polyvinyl chloride

PVC roofing materials feature hot-air welded seams, polyester reinforcements, and colour options. They offer chemical and UV resistance, flexibility, fire resistance, and long-lasting durability.

5. Systems of modified bitumen roofing

Modified bitumen roofing systems combine asphalt and a chemical polymer, improving flexibility and temperature resistance. Applied using the torch, hot asphalt, or cold process adhesives, these durable membranes feature increased membrane thickness, polyester reinforcements, and coated surfaces.

6. Hybrid roofing system video

The Hybrid system uses SBS-modified bitumen products and Sarnafil G 410 Feltback membrane for long-term substrate adhesion. It's suitable for metal decks and lightweight insulated concrete, featuring a non-woven fiberglass mat.

7. Built-up roof

Built-up roofs (BUR) are US-based systems made of alternating layers of bitumen and reinforcement fabrics. They have been used for over a century and are typically fully adhered when applied directly to roof decks or insulation. The reinforcing fabrics include glass-fiber mats or organic mats. Built-up roof systems use aggregates, cap sheets, asphalt, coatings, and polymer-modified bitumen membranes. Hybrid roof systems combine a built-up roof membrane with multiple plies.
