The two most often used sealants on the market are polyurethane sealants, and silicone sealants. One of the main differences between urethane versus polyurethane is that urethane is soft and malleable, and polyurethane is rigid and firm. Unlike other types of coatings or paints, it can bridge hairline cracks to complete an airtight waterproof seal. Butyl acrylic coatings are solvent-based, waterproof, flexible, and can offer excellent resistance to ponding water (water that remains on the roof surface for more than 48 hours) for flat roofs. It is moisture- and corrosion-resistant. __CONFIG_colors_palette__{"active_palette":0,"config":{"colors":{"f3080":{"name":"Main Accent","parent":-1},"f2bba":{"name":"Main Light 10","parent":"f3080"},"trewq":{"name":"Main Light 30","parent":"f3080"},"poiuy":{"name":"Main Light 80","parent":"f3080"},"f83d7":{"name":"Main Light 80","parent":"f3080"},"frty6":{"name":"Main Light 45","parent":"f3080"},"flktr":{"name":"Main Light 80","parent":"f3080"}},"gradients":[]},"palettes":[{"name":"Default","value":{"colors":{"f3080":{"val":"rgb(23, 23, 22)","hsl":{"h":60,"s":0.02,"l":0.09}},"f2bba":{"val":"rgba(23, 23, 22, 0.5)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.5}},"trewq":{"val":"rgba(23, 23, 22, 0.7)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.7}},"poiuy":{"val":"rgba(23, 23, 22, 0.35)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.35}},"f83d7":{"val":"rgba(23, 23, 22, 0.4)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.4}},"frty6":{"val":"rgba(23, 23, 22, 0.2)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.2}},"flktr":{"val":"rgba(23, 23, 22, 0.8)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.8}}},"gradients":[]},"original":{"colors":{"f3080":{"val":"rgb(23, 23, 22)","hsl":{"h":60,"s":0.02,"l":0.09}},"f2bba":{"val":"rgba(23, 23, 22, 0.5)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.5}},"trewq":{"val":"rgba(23, 23, 22, 0.7)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.7}},"poiuy":{"val":"rgba(23, 23, 22, 0.35)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.35}},"f83d7":{"val":"rgba(23, 23, 22, 0.4)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.4}},"frty6":{"val":"rgba(23, 23, 22, 0.2)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.2}},"flktr":{"val":"rgba(23, 23, 22, 0.8)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.8}}},"gradients":[]}}]}__CONFIG_colors_palette__, {"email":"Email address invalid","url":"Website address invalid","required":"Required field missing"}, __CONFIG_colors_palette__{"active_palette":0,"config":{"colors":{"f3080":{"name":"Main Accent","parent":-1},"f2bba":{"name":"Main Light 10","parent":"f3080"},"trewq":{"name":"Main Light 30","parent":"f3080"},"poiuy":{"name":"Main Light 80","parent":"f3080"},"f83d7":{"name":"Main Light 80","parent":"f3080"},"frty6":{"name":"Main Light 45","parent":"f3080"},"flktr":{"name":"Main Light 80","parent":"f3080"}},"gradients":[]},"palettes":[{"name":"Default","value":{"colors":{"f3080":{"val":"rgba(23, 23, 22, 0.7)"},"f2bba":{"val":"rgba(23, 23, 22, 0.5)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}},"trewq":{"val":"rgba(23, 23, 22, 0.7)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}},"poiuy":{"val":"rgba(23, 23, 22, 0.35)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}},"f83d7":{"val":"rgba(23, 23, 22, 0.4)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}},"frty6":{"val":"rgba(23, 23, 22, 0.2)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}},"flktr":{"val":"rgba(23, 23, 22, 0.8)","hsl_parent_dependency":{"h":60,"l":0.09,"s":0.02}}},"gradients":[]},"original":{"colors":{"f3080":{"val":"rgb(23, 23, 22)","hsl":{"h":60,"s":0.02,"l":0.09}},"f2bba":{"val":"rgba(23, 23, 22, 0.5)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.5}},"trewq":{"val":"rgba(23, 23, 22, 0.7)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.7}},"poiuy":{"val":"rgba(23, 23, 22, 0.35)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.35}},"f83d7":{"val":"rgba(23, 23, 22, 0.4)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.4}},"frty6":{"val":"rgba(23, 23, 22, 0.2)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.2}},"flktr":{"val":"rgba(23, 23, 22, 0.8)","hsl_parent_dependency":{"h":60,"s":0.02,"l":0.09,"a":0.8}}},"gradients":[]}}]}__CONFIG_colors_palette__. foot commercial roof, it will usually cost between $4.00 and $7.00 per square foot in materials and labor to install a typical SPF roofing system.
