Flat Roof Waterproofing Solutions
Flat roofs have a tough job to do. They take the brunt of standing water, constant sunlight, and the natural wear and tear of aging materials. That’s why Gaco’s silicone-based systems are such a reliable choice—they form a seamless, fully bonded waterproof layer that stays flexible and strong, even in extreme conditions.
Why choose Gaco for your flat roof?
- Long-lasting protection for a wide range of surfaces, including asphalt, felt, GRP, PVC, concrete, and EPDM.
- Performs far better than traditional felt and bitumen coatings.
- Perfect for roofs where water tends to collect.
- Cold-applied system—so there’s no need for flames or hot works.
- Backed by warranties when installed by Duratite Approved Installers.
