Service Area · Harwinton, CT
As a Harwinton metal roof coating contractor, we flash every curb, vent, and solar mount before coating commercial metal roofs.

Harwinton metal roof coating on a roof full of equipment is mostly detail work. Every rooftop unit, exhaust fan, pipe vent, and solar mount is a hole in the roof that moves differently from the panels around it.
Each penetration gets its flashing repaired and reinforced coating before the field coat. Solar racking stays in place where its mounts can be sealed, and we coordinate with the solar owner where panels must be lifted.
On equipment-heavy Harwinton roofs, these are the leak points that matter most.
Detailing an equipment-heavy Harwinton roof pays back in four ways.
Flashed and coated curbs stop the most common source of ceiling stains.
Many mounts are sealed in place, avoiding a full panel removal.
Field coat and details tie together so no joint is left open.
Marked walk paths around units help technicians avoid scraping the coating.
Harwinton roofs with lots of equipment still fit one of these five options.

The standard Harwinton system for steel roofs, with every curb and mount detailed first.

Detail work around equipment comes before the field coat on every Harwinton job.
We map every unit, fan, vent, and solar mount, check each flashing, and confirm which units can be shut down during work.
Residue around fans and units is cleaned off so primer and coating stick.
Curbs, boots, and mounts get flashing repair and fabric set in coating.
The field coat ties into every detail, and we mark walk paths for service technicians.

Each penetration adds detail work, which moves a roof within the published $2.50 to $4.00 per square foot range. The estimate counts curbs, vents, and mounts so the detail work is clear.
Units near the work are shut down or covered for the hours the crew sprays nearby, set up with maintenance staff ahead of time.
We work from Bristol and cover Harwinton regularly. Call or use the estimate form to set up a roof walk.
Often they can stay, with mounts sealed in place. Where a panel blocks access to failing steel, the solar owner arranges removal.
Marked walk paths and pads around units keep foot traffic off the open field. Scrapes from service visits should be reported so they get sealed.
Harwinton's building department decides from the scope of the roof work. Unit swaps or solar changes made alongside the coating can carry their own permits, so those trades should check with the town too.
Coordinate the timing. Replacing a unit after coating means new curb work through fresh coating, so it is cheaper to swap the unit first and coat around its new curb.
It can, with a new curb cut through the coated panels. The new curb gets flashed and coated to match, so tell us about planned equipment so the work is done in one visit when possible.
Tell us what equipment sits on the roof. We will check every penetration and price the coating.
