Roof Base Layer
Roof Base Layer
The first line of defence for typhoon-zone solar roofs. The base layer combines a high-strength waterproof underlayment with structural support battens, creating a fully breathable, 100% waterproof platform that prevents moisture buildup under the PV tiles. Designed specifically for coastal and industrial projects, it eliminates leaks, condensation and corrosion even in salt-spray environments. Your crew lays it exactly like standard roofing underlayment – no extra training, no callbacks.
Composite Sloped Roof Waterproof Membrane
Made from non-woven fabric compounded with modified asphalt, serving as the primary roof base waterproof layer. Directly laid and nailed in place, its special self-healing structure ensures no leakage from nail holes, providing a reliable waterproof barrier; suitable for sloped roofs, with optional installation of water flow strips on top.
Eave Strip / Batten Strip
Made from corrosion-resistant treated wood, typically arranged by the buyer. Recommended size 3cm×5cm; eave strips placed perpendicular to the ridge on the roof base to secure batten strips and guide rainwater drainage while promoting ventilation; batten strips installed parallel to the ridge, providing stable tile support, separating the waterproof layer from tiles for efficient drainage and system durability.
Aluminum Foil Composite Insulation Waterproof Underlayment
A composite layer of aluminum foil and waterproof materials, placed over the roof base or waterproof membrane, ensuring tight overlaps. It combines waterproofing with heat reflection, blocking summer heat radiation while retaining winter warmth for energy-efficient insulation; easy to install without additional fasteners.
Installation as simple as building with blocks
Sunlit’s photovoltaic rooftop systems feature an innovative overlapping structure and modular design that significantly streamline the installation process. Whether for new construction or retrofitting existing roofs, our products adapt quickly to facilitate efficient construction, saving both time and costs.
