Kaiser Siding & Roofing Before & After!

The roof in these photos wasn’t leaking. The homeowner wasn’t dealing with an emergency, and there was no tarp on anything. From the street it looked like a roof that had a few more years in it.

It didn’t. And that gap, between a roof that looks acceptable and one that’s actually still protecting the house, is where most replacement decisions get made too late.

Here’s what changed on this Suwanee, GA home, and how to tell where your own roof sits.

The Before and After

Look at the before photo again, specifically at the large slope above the carport. The color isn’t uniform. There are lighter, washed-out areas mixed with darker sections. That mottling is granule loss, and it’s the single most reliable sign a roof is past the point where repair makes sense.

Granules are the shingle’s protection against UV. Once they’ve worn off across a whole plane rather than in isolated spots, the asphalt underneath is exposed and begins drying, cracking, and shrinking. You can’t put granules back. At that stage every repair is buying months, not years.

What We Found on This Roof

Widespread granule loss across the main slopes, with the worst of it on the south and west exposures where sun load is heaviest. That’s the typical pattern. Roofs almost never wear evenly, and the side facing the afternoon sun gives out first.

The detached carport roof was in the same condition, which is common and easy to overlook. It was installed at the same time as the main roof and weathered identically, but because it’s a smaller structure that nobody looks at, it often gets left off a scope of work. Replacing one and not the other means being back on a ladder in two years.

A full tear-off matters here. Layering new shingles over old is cheaper and faster, but it hides the condition of the decking, adds weight the framing wasn’t designed for, and traps heat that shortens the life of the new shingles. It also voids most manufacturer warranties. We tear off to the deck so we can see what’s underneath and replace anything soft before it gets covered up again.

Repair or Replace: How to Decide

This is the question every homeowner is actually asking, and the honest answer depends on three things.

How old is the roof?

Standard architectural shingles run roughly 20 to 25 years in the Southeast, less if ventilation is poor. Under 12 years, most problems are worth repairing. Past 18, you’re generally spending money on a roof you’ll replace soon anyway. The middle is a judgment call.

Is the damage isolated or everywhere?

A failed pipe boot, a section of lifted shingles after a storm, damaged flashing at a chimney. All of these are repairs, regardless of roof age. Granule loss across whole planes, widespread curling, or multiple leak points in different areas mean the roof itself is failing, not one component of it.

What does the attic say?

Soft or stained decking, daylight visible through the deck, or a history of repeated leaks in different spots all argue for replacement. So does a roof that’s already been layered over once.

There’s also a practical threshold: when repair costs start approaching 25 to 30 percent of replacement cost, replacement usually wins on value. You get a new warranty, a fresh service life, and you stop paying for the same problem repeatedly.

A roof that’s simply aging with no storm event behind it is a planning decision, not an emergency. That’s the best position to be in. You can get estimates, compare options, and schedule on your own timeline. Our maintenance program is designed to catch roofs at this stage rather than after a leak.

What a Replacement Actually Involves

Most residential replacements take one to two days. The sequence:

• Protection. Tarps over landscaping, plywood against siding at drop zones, dumpster positioned to keep debris off the drive.
• Tear-off. Old shingles and underlayment removed down to the bare deck.
• Deck inspection. This is the part you’re paying for that nobody sees. Soft, delaminated, or rotted sheathing gets replaced now, while it’s accessible.
• Underlayment and ice barrier. Synthetic underlayment across the field, with a waterproof membrane at eaves and valleys.
• Flashing. New pipe boots, new step flashing at walls and chimneys. Reusing old flashing is a shortcut that shows up as a leak in three years.
• Shingles and ventilation. Starter course, field shingles, ridge cap, and ridge vent, with old box vents closed off so they don’t short-circuit the new airflow.
• Cleanup. Magnet sweep of the drive, yard, and beds. This is the part homeowners remember.

Why Waiting Costs More

A roof at the end of its life doesn’t fail gradually in a way that gives you a warning. It holds, and then it doesn’t, usually during a storm and usually at the worst time.

What changes when you wait:

Decking replacement. Once water gets past a failing shingle layer, it soaks the sheathing. Sheathing replacement is priced per sheet on top of the replacement cost, and it’s the most common reason a quote comes in higher than expected.

Interior repairs. Drywall, insulation, paint, and occasionally flooring. None of that is roofing work, and all of it is on you.

Emergency pricing and scheduling. After a significant storm, every roofer in the metro is booked. A planned replacement gets scheduled when it suits you. An emergency gets you whoever is available.

Insurance complications. Carriers distinguish sudden storm damage from gradual deterioration. A roof that failed because it was worn out is a maintenance issue, not a covered loss. Waiting long enough can move damage from one category to the other. If a storm has come through, our storm damage team can document it while the claim is still viable.
