Best Metal Roof Paint, Sealants and Coatings

SiliconEx 500 and SealEx 100 provide high-performance waterproofing for metal roofs. SiliconEx 500 is a 100% silicone, solvent-free formula offering hydrophobic protection and permanent ponding water resistance. For base membrane protection, SealEx 100 provides 500% elongation, resisting rust, corrosion, salts, and acids. Both coatings create seamless barriers that seal joints, stop existing leaks, and protect metal roof assemblies from severe moisture exposure and weather conditions.

Yes. SiliconEx 500, TropEx 310, and ElastEx 200 are designed for flat and low-slope roofing applications, including metal roofs. SiliconEx 500 is formulated for areas subject to permanent ponding water, curing into a seamless moisture-cured membrane. For low-slope metal roofs requiring restoration, using ElastEx 200 as an elastomeric basecoat paired with an acrylic or silicone topcoat provides flexible crack bridging during seasonal thermal movement.

Silicone coatings like SiliconEx 500 are solvent-free, moisture-curing formulations that provide permanent ponding water resistance and high solar reflectivity. They adhere well to metal and multiple roofing substrates. Acrylic coatings like TropEx 310 and SolarEx 300 are water-based, low-VOC systems offering strong dirt pickup resistance, UV protection, and elastomeric flexibility. Acrylics require positive drainage, whereas silicone handles continuous standing water without breaking down.

SolarEx roof coatings can be applied using a brush, roller, or airless sprayer. For airless spray application of SolarEx 300, equipment capable of 3,000 PSI or higher is compatible. SealEx 100 and ElastEx 200 also support brush, roller, or airless spray methods. Application method depends on project scale, ranging from single-pail maintenance jobs to large commercial installations using drums or pallets.

SolarEx cool roof coatings reflect significant solar radiation to minimize heat absorption through metal roof decks. TropEx 310 achieves an initial reflectivity of 0.83, while SolarEx 300 reflects 90%+ of UV and infrared radiation using high titanium dioxide pigment levels. By keeping roof surface temperatures cooler during hot weather, these reflective topcoats help reduce interior heat transfer and lower building utility expenses.

SolarEx systems offer warranties of up to 20 years for SiliconEx 500 or 10 years for TropEx 310 depending on the system applied. Products are supplied in 1-gallon containers, 4- to 5-gallon pails, 55-gallon drums, and bulk pallets holding 36 5-gallon buckets or 180-gallon quantities.
