Made to fit your building.
We measure the angles before the job and fabricate flashings and trim in our shop. The final adjustments happen on site, where the fit can be checked against the building.

Experience behind every detail
Shane spent about ten years in residential roofing before moving into commercial work for the next twenty. Along the way, he completed a union roofing apprenticeship, worked on demanding roof systems, and learned to track leaks that were anything but obvious.
He started W. Forrest Roofing & Sheet Metal in 2025, bringing that experience into a company of his own. Together with his son and experienced roofers he has known for years, he is building around one clear standard for the whole crew.
The idea is straightforward: bring the best details from commercial work to every customer, including the homeowner who wants a carefully built roof.
W. Forrest honors Shane’s late brother, Wesley Forrest, who worked alongside him for years. It is a family name with a personal responsibility behind it.
Our standard
“A roof is only as good as its weakest link.” That’s why we spend our time on the edges, transitions, and penetrations, as well as the surface you see.
We measure the angles before the job and fabricate flashings and trim in our shop. The final adjustments happen on site, where the fit can be checked against the building.
Our flashings and trim use 24 and 26 gauge pre-finished steel. Substantial materials are part of the standard, alongside specialty copper where the project calls for it.
On a residential replacement, tear-off and dry-in come first. Gutters are installed and sealed before the shingles, so the details overlap in the right direction.
Gutter aprons, roof edges, and intersecting systems get careful attention. A Wisconsin roof needs to account for winter snow and ice as well as summer rain.
Training. Then decades in the field.
Shane’s apprenticeship certificate records 6,000 hours of training as a roofer and waterproofer. That foundation informs the way W. Forrest follows installation requirements and works through a roof system.
The same care shows up in the small things, including deliberate nail placement and finishing one stage before the next begins.
