Built on trust. Designed to last.
A family business serving Northeast Indiana for over thirty-four years. Roofs, custom homes, and remodels, backed by a 10-year craftsmanship warranty.
What we do
From a single torn shingle to a full custom home, the same family stands behind the work.
Tear-offs, full replacements, and targeted repairs on residential roofs, backed by a 10-year craftsmanship warranty.
From foundation to finish trim. One crew, one standard, start to keys.
Kitchens, baths, basements, additions, built to match the rest of the house, not patched on top of it.
Decks, framing, structural work. The parts other contractors won't touch. If it's built with hands, we build it.
Recent work

About GNG
GNG Roofing & Construction has been working out of Grabill for more than three decades. We answer our own phones. We show up to our own estimates. The same name on the truck is the name on the warranty.
We don't subcontract the work and disappear. Roofing, custom builds, and remodels are all handled by people we know and trained ourselves, because that's the only way we know how to stand behind a 10-year warranty without flinching.
Word of mouth
