Anatomy of a G.S.G roofSix steps. Zero
Six steps. Zero
shortcuts.
This is a real re-roof from one of our Tri-Cities jobs, start to finish. Most of a roof's life is decided by the layers you never see. Here's every one.
Inspect the old roof
We walk it, check for soft spots, lifted shingles and worn vents, and give you a straight answer on what it needs.
Full tear-off
Everything comes off down to the wood. No layering new shingles over old problems.
Deck repair
Damaged or soft sheathing gets replaced so your new roof sits on a solid, flat base.
Underlayment
Synthetic underlayment rolled out and cap-nailed tight. Your second line of defense against water.
Architectural shingles
Laid straight with clean lines, proper nailing and sealed flashing around every vent and pipe.
Ridge cap & clean-up
Ridge cap on, vents sealed, yard swept for nails. You get a finished roof, not a mess.
Before & After

See the difference.
Tired white siding to a deep blue-gray with dark trim. Same house, same windows, completely new curb appeal.
