In this article, we’ll explore practical tips and best practices to keep your metal roof in top shape, safeguarding your home and enhancing its curb appeal.

Maintaining a metal roof involves a combination of routine inspections, cleaning, and timely repairs. Regular checks can help identify potential issues before they escalate, such as rust, loose fasteners, or debris accumulation. Cleaning your roof not only improves its appearance but also prevents the buildup of materials that can lead to corrosion or other damage.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
