7,10 years The Manufacturer’s Material Warranty, from Apoc, is for 10 years because it is their Siliconized version of their acrylic Apoc 770 coating which carries a 7 year Material Warranty by Apoc.		7 Years Labor, 50 Years Material by Manufacturer Like all licensed Roofing Contractors in Hawaii, Leakmaster is limited to 7 years for their Labor Warranties by State Law. However, the Manufacturer gives a 50 Year Material Warranty subject to their conditions.		5,7 & 14+ years All Hawaii roofing contractors are limited to a maximum of 7 years labor and material warranty. However that warranty can be extended every seven years after a job site inspection and a new top coat is applied. There is an additional cost for that service. Ask Leakmaster for details.		7-15 years Sometimes the Manufacturer will give a 20 year warranty under ideal conditions.

Limited effectiveness for heavy ponding water–no Lipacyl Doesn’t dry as fast as Hawaiian SunGuard’s Fast Dry No Ceramic Titanium HeatShield		Very slippery when moist, not recommended for steep sloping roofs Can not be tinted, only available in white, tan and grey Not recommended for asphalt shingles Not a long track record in Hawaii		Heavy ponding water can create problems. Use HSG silicone roof coating in this case Insist on a fabric reinforcement and a min. of 4-5 gals. per 100 SF if you have ponding water For good adhesion use an epoxy primer		Silicones are very slippery when wet. Use caution on sloped roofs. Smelly during application. Solvent based Silicones are shiny and can look funny on shingles.

We use Apoc 780 a lot as a moderately priced roof coating where there is not excessive ponding water. We define that as water that does not burn off after 24 hours of no rain. Customers who ‘Do It Themselves’ love its ease of use. We sell a lot of it at our GEO store.		If your roof is having trouble standing up to the elements, it’s time for GacoRoof Silicone Roof Coating. GacoRoof offers long-term waterproofing protection in a bright white reflective silicone coating. Until now, the only choice for flat roofs were temporary fixes with acrylics which can erode from the sun and rain in 3 to 5 years. Finally, with GacoRoof, building owners can coat their roofs with the same long-lasting waterproof coating that professional contractors rely upon.		This is our top of the line Acrylic coating which we have used as our flag ship product for 8 years. We believe this to be the best acrylic coating on the market. It can also be tinter to many different colors, whereas silicone coatings are much more limited.		This is a quality silicone roof coating with 95% solids. Ponding water does not seem to affect it. When it does get mildew growth in the ponding areas it can be cleaned off very easily. We don’t recommend it for shingles because of the high sheen.
