Add 15 years to your roof.
In a single day.
GoNano is a clear, hydrophobic nano-coating that re-bonds loose granules, repels water, and shields asphalt shingles from the UV that ages them. No tear-off. No disruption. No reason to replace a roof you can restore.

From our family to yours — Top Notch Roof Coating is built on a simple belief: your home is where your family's story unfolds, and the roof above it deserves the same care you give everything else.

A microscopic shield, a macro-scale result.
GoNano penetrates the asphalt matrix and forms a covalent bond at the molecular level. The result: water sheets off, granules stay locked in place, and UV degradation slows to a fraction of its natural pace.
2,400+ roofs. Zero callbacks.
