Roof replacement in progress with synthetic underlayment installed

// Roof Replacement

When A Repair Isn't Enough

A roof replacement makes sense when the damage is spread across the whole roof, the shingles are past their service life, or the decking underneath has started to fail. GNG replaces residential roofs across Fort Wayne, Grabill, and Northeast Indiana, and every job is backed by GNG's 10-year craftsmanship warranty.

If the problem is contained to one area, say so and we will price a repair instead of a replacement. Not sure which one you are looking at? Start with a free roof inspection. Replacement is one of the five pages under our roofing services.

// How It Works

The Replacement Process

Same crew from the first estimate to the final walkthrough.

1

Inspection & Estimate

We check the roof and attic, then give you a written estimate that covers the full scope of work.

2

Material Selection

You choose the profile and color. We'll show you samples, not just a catalog page, and walk the tradeoffs between asphalt shingles and metal roofing for your roof.

3

Scheduling

We plan around Indiana weather and confirm a start date once materials are ordered.

4

Tear-Off & Install

Old roofing comes off, decking gets inspected and repaired as needed, then the new roofing system goes on.

5

Walkthrough & Warranty

We walk the finished roof with you and go over the 10-year craftsmanship warranty.

// Definition

What Is A Roof Replacement?

A tear-off and a roof-over are not the same job, even when the finished roof looks identical.

A roof replacement is a full tear-off: every layer of old shingle comes off, the wood decking underneath gets inspected and repaired, new underlayment goes down, and a new roof is installed. A roof-over, by contrast, lays new shingles on top of old ones and hides whatever is wrong with the deck. A roof-over is faster and cheaper on the day it is installed. It is also the reason some roofs get torn off twice.

The practical difference is what happens to the decking. On a tear-off, rotted or delaminated sheathing gets found and replaced while it is visible and cheap to fix. On a roof-over, it stays where it is, under two layers of shingles, with the new nails going through both. That is also why many manufacturers restrict their warranty coverage on layovers, and why some local codes cap the number of layers allowed on a house.

GNG quotes replacements as full tear-offs. If a roof-over is genuinely a reasonable option for your house, we will say so and explain the tradeoff, but we will not quietly price one to look cheaper than the bid next to it.

// Straight Answers

Roof Replacement Questions, Answered

How long does a roof replacement take?

Most single-family roof replacements in the Fort Wayne area take one to three working days once the crew is on site. Pitch, the number of stories, how many layers of old roofing have to come off, and how much decking turns out to be rotted are the four things that move that number. Weather moves it too, and we do not tear off more roof than we can dry in the same day. Your written estimate carries a specific schedule for your house before anything starts.

How much does a new roof cost in Indiana?

Roofing is priced by the square, which is 100 square feet of roof surface. The price moves with the roof's area, its pitch, the number of stories, the layers being removed, the decking that has to be replaced, and how many valleys, dormers, chimneys, and skylights have to be flashed. Material sets the rest: 3-tab costs less than architectural shingles, and both cost less up front than standing seam metal roofing. We price the roof after we have been on it.

Do I need a permit to replace my roof in Allen County?

Permit rules for reroofing are set locally by the city or county building department where the house sits, not by the state, and they are not identical between Fort Wayne and the smaller Allen County towns around it. We pull whatever the local jurisdiction requires and schedule any inspection as part of the job, so it is not something you have to chase. Work that goes past the covering itself, such as structural repair or a change of roofing material, can change what has to be permitted.

How do I know if I need a replacement instead of a repair?

Three signs point to replacement: damage across the whole roof rather than in one spot, shingles curling or shedding granules everywhere, and a roof past roughly 20 years old. Soft or spongy decking is the fourth, and it settles the question, because a deck that has been wet for years cannot be patched. One leak on an otherwise sound roof is a repair instead of a replacement. We tell you which one you are looking at after the free inspection, in writing.

Do I have to move out during a roof replacement?

No. A roof replacement happens entirely outside the house, so you can stay in it and most people do. Expect real noise for the tear-off and the nailing, which is the loudest part of the job and runs through the working day. If someone in the house works nights or naps during the day, plan around it. Vehicles need to be out of the driveway so the crew can stage materials and the dumpster.

How do I get ready for the crew?

Four things help. Move vehicles out of the driveway and away from the house so materials and debris have a landing zone. Take pictures and mirrors off walls that share a rafter line, because nailing vibrates them. Move anything fragile out of the attic and off garage shelves. And clear patio furniture, grills, and planters back from the walls. We tarp what we can and magnet-sweep the yard when the job is done.

// What Moves The Number

What Actually Drives Cost And Timeline

Six things move the price and the schedule of a roof replacement more than anything else: the roof's square footage, its pitch, the number of stories, how many layers of old roofing have to come off, how much decking needs replacing, and how complex the roof is to flash. A simple one-story gable roof and a two-story roof with four valleys, two dormers, a chimney, and a skylight can have the same footprint and land in very different places on both counts.

Pitch is the one homeowners underestimate. Past a certain slope a crew cannot walk the roof freely and has to work off staging and harnesses, which slows every stage of the job. Layers matter for the same reason: a second layer of shingles doubles the tear-off and the disposal weight. Decking is the wildcard, because nobody can measure rot through a shingle. We give you a decking price per sheet in the written estimate so that if we find it, you already know what it costs.

The things that do not move the price much are the ones sales-driven roofers push hardest: color, and the season. We schedule around Indiana weather rather than around a discount calendar.

// FAQ

Roof Replacement Questions

How long does a roof replacement take? ▾

It depends on the roof's size, pitch, and material. Your written estimate will include a specific schedule for your home, weather permitting.

Will you handle my insurance claim? ▾

Yes, if the replacement is storm-related we'll document the damage and work directly with your adjuster.

Do I need a permit for a full roof replacement? ▾

Most municipalities in Northeast Indiana require one. We pull and handle any required permits as part of the job.

What happens if you find rotted decking during the tear-off? ▾

We stop, show you, and price the decking repair before it goes in. Rotted sheathing is the most common surprise on a tear-off, and it is the one thing that cannot be judged with certainty until the old roofing is off. Nothing gets covered over quietly.
