From The First Call To The Final Walkthrough
// How It Works
The Same Sequence, Every Job
A roof or a remodel goes wrong when steps get skipped or handed off to someone who wasn't there for the earlier ones. GNG runs every job through the same nine steps below, with the same crew from start to finish. This is the actual sequence, not a marketing summary of it.
// Step By Step
How A Project Runs
First Call & Free Estimate
You call or fill out our contact form and we set a time to come look at the roof or project in person. The estimate is free and written, and covers the full scope of the work.
Inspection & Measurement
We walk the roof and attic, check the decking, flashing, and ventilation, and measure the job so the estimate reflects what is actually there, not a guess from the driveway.
Material Selection
You choose between asphalt shingle and metal roofing, and see real samples, not a catalog page. We walk the tradeoffs for your roof, your budget, and how long you plan to own the house.
Tear-Off
Every layer of the old roofing comes off down to the deck. Nothing gets covered up or roofed over, and the old material is hauled away.
Deck Inspection & Repair
With the old roof off, we inspect the wood decking underneath and repair or replace any rotted or damaged boards before anything new goes down.
Underlayment & Flashing
Synthetic underlayment goes down across the whole roof, with ice and water shield at eaves, valleys, and penetrations, and flashing detailed at walls, chimneys, and vents.
Installation
New shingles or metal roofing go on to manufacturer specification, installed by the same crew that gave you the estimate and did the tear-off.
Cleanup & Magnet Sweep
We haul away debris and run a magnetic sweep of the yard and driveway to catch stray nails before the crew leaves the site.
Final Walkthrough & Warranty
We walk the finished work with you, answer questions, and go over the 10-year craftsmanship warranty in writing before we consider the job done.
// Amish-Owned
What Generational Trade Training Means Here
GNG Roofing & Construction is an Amish-owned, family business working out of Grabill. The people on your roof were trained in the trade inside the business, by people already doing the work, not hired off a general labor pool and sent out with a crew they just met.
What that means in practice is straightforward. There is one crew, not a rotating set of subcontractors picked for whoever is available that week. The person who inspects your roof and writes your estimate is someone who will also be on the job, from tear-off to the final walkthrough. Nothing gets handed off to a crew GNG doesn't know.
That is also the reason there is no subcontracting. A subcontractor wasn't in the room when your estimate was written and won't be the one to come back if something needs attention under warranty. On a GNG job, the same people are on the roof the whole way through, which is what lets the company stand behind a 10-year craftsmanship warranty without qualifying it.

// FAQ
Our Process, Answered
How long does a roof replacement take once the crew is on-site? ▾
Most single-family roof replacements in the Fort Wayne area take one to three working days once the crew is on site. Steeper pitches, multiple layers of old shingles, and bad decking add time. Your written estimate gives a specific schedule for your house before we start.
What happens during the free estimate? ▾
We inspect the roof and attic in person, measure the roof, and check the decking, flashing, and ventilation. You get a written estimate that covers the full scope of work, so nothing gets added later that wasn't already priced in.
Do you clean up the job site when the work is done? ▾
Yes. We haul away the old roofing and run a magnetic sweep of the yard and driveway to pick up stray nails before the crew leaves. That is a standard part of every job, not an add-on.
Do you subcontract any part of the work? ▾
No. GNG Roofing & Construction does not subcontract roofing, remodeling, or custom home work. The crew that inspects your roof and writes your estimate is the same crew that finishes the job.
