Overview

A replacement is your one chance to fix what is underneath.

When a roof reaches the end of its service life, patching it stops being economical. A full replacement lets us correct what is hidden underneath — rotted decking, undersized ventilation, failed flashing — instead of covering it up. We handle everything from tear-off through final inspection and clean-up, and we walk you through material, color, and warranty options before a single nail goes in.

Most of what shortens a roof’s life is not the shingle. It is intake ventilation that got blocked when somebody insulated the attic, a valley cut the wrong way, drip edge that was never installed, or decking that has been quietly soft for three winters. None of that is corrected by laying another layer over the top of it, and none of it is even visible until the old roof is off. That is the whole argument for a tear-off, and it is why we will not install over an existing roof.

Scope of work

What's included.

Every replacement we quote includes all of the following. If a bid you are comparing is cheaper, it is worth checking which of these lines is missing from it — that is almost always where the difference lives.

What to expect

Tear-off to magnet sweep, usually inside a day.

Most Michiana homes are off and re-roofed in a single day; steeper roofs and multiple layers can run to three. Here is what that day actually looks like on your property, in order.

Step01 / 04

Material and colour decided first

You pick a profile and a colour with real samples in daylight, not off a screen. We order shingle, underlayment, ridge vent and accessories, and material lands a day or two ahead so nothing on installation day depends on a supplier turning up.

Step02 / 04

The property gets protected

Sheeting over the beds and landscaping, plywood against the elevations, and the drive kept clear for the trailer. Tear-off is a violent process by nature — the point is that none of it lands on your yard.

Step03 / 04

Tear-off, then the honest conversation

The old roof comes off down to bare deck, which is the moment we find out what the decking is really like. Anything soft or delaminated gets photographed and shown to you on the ground before we cut a single sheet of replacement sheathing. You approve the extra before it is an invoice.

Step04 / 04

Dry-in the same day, then finish

Ice-and-water shield at the eaves and valleys, synthetic underlayment across the field, then shingle, ridge and ventilation. We never leave a deck open overnight. At the end the crew runs magnets over the drive, the beds and the lawn, and we walk the finished roof with you.

Worth knowing

The detail that decides whether the roof lasts

Ventilation. A roof needs balanced intake at the soffit and exhaust at the ridge, and a great many attics around here have one without the other — usually because insulation was pushed tight into the eaves at some point and nobody noticed. We check intake on every replacement and will tell you if the ridge vent you are paying for has nothing to pull air from. Exhaust with no intake is a common way to void a shingle warranty without anyone realising it happened.

Common questions

Roof Replacement, answered.

If your question is not here, call (574) 334-6597 and ask. We would rather spend five minutes on the phone than have you guess.

How long does a roof replacement take?

Most Michiana homes are torn off and re-roofed in a single day. Larger or steeper roofs, and homes with multiple layers to remove, can run two to three days. We schedule around the weather and never leave a roof open overnight.

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

Curling or cupping shingles across the whole roof, granules filling your gutters, daylight visible in the attic, or a roof past 20 years old usually point to replacement. If the damage is isolated to one slope or one penetration, a repair is normally the smarter spend — and we will tell you so.

Do you replace rotted decking?

Yes. We cannot see the decking until the old roof is off, so we inspect it during tear-off and replace anything soft or delaminated. We show you the damage and confirm the cost before we install the replacement sheathing.
