Photovoltaic Solar Panel Rail Rooftop Installation Adhesives

If you’re installing solar panel arrays on a metal or concrete roof, eliminate the need to drill holes. Our adhesives securely attach photovoltaic solar panel mounting rails to the rooftop without damaging the roof’s structural integrity or letting elements such as rain and bacteria seep in through these holes.

Benefits of Using Adhesives for Solar Panel Bonding

No Drilling

Our adhesives secure solar panel rails to the roof eliminating the need to drill holes, which can potentially let in moisture or bacteria.

Withstands Strong Winds

Our adhesives are very flexible – achieving 190% elongation – enabling the rail to absorb thrust and shock produced by high wind speeds.

Faster Installation Times

Drilling and tightening bolts takes time, time that could be spent on your next job.    

Protect Roof Warranty

Since solar arrays are installed without drilling holes, the roof’s warranty remains intact.
