Final Thoughts

Each EPDM roofing material option caters to different needs. ClassicBond is the cost-effective all-rounder for general flat roofs, while Skyguard is perfect for small DIY garden projects.

For refurbs, overlays, or heavy-duty applications, both Resitrix and ClassicBond Pro deliver premium strength and durability, with Resitrix offering reinforced, self-adhesive performance for commercial and detailed work, and ClassicBond Pro providing fleece-backed flexibility and ease of use on domestic refurbishments. In most cases, excluding Skyguard, these membranes can generally be used for the same types of projects; the key is scrutinising which system is the most appropriate for your roof.
