Our Roofit Restoration crew is on the roof this week in East Cobb, completing a full roof replacement on a beautiful two-story home off Mark Hall Court in Marietta. This project is a textbook example of something every metro Atlanta homeowner should understand: you never really know what's under your shingles until they come off.

What We Found: 18 Sheets of Compromised Decking

On July 11th of 2026, when we tore off the old shingles, we found decking that had to go. In total, 18 full sheets of OSB (oriented strand board) needed to be replaced before a single new shingle could be installed.

Here's the thing: from the ground, and even from the surface of the roof, this house didn't look like it was hiding that kind of damage. That's normal. Roof decking is the structural wood layer your entire roof system sits on. When moisture gets past aging shingles, whether through failed seals, storm damage, or worn underlayment, the decking absorbs it quietly. Over Georgia's humid summers and repeated storm cycles, that moisture turns solid decking soft, delaminated, and unable to hold a nail.

New shingles installed over bad decking are a wasted investment. The roof looks great from the street, but the nails have nothing solid to grip, and the whole system fails early. That's why our crew inspects every square foot of decking during tear-off and replaces what's compromised. No shortcuts, and no covering it up.

Why Marietta and East Cobb Roofs Take a Beating

East Cobb's mature tree canopy is part of what makes neighborhoods like this one so desirable. It's also part of what makes roof maintenance so important here. Overhanging trees mean shade and debris that hold moisture on the roof surface, plus limbs that can damage shingles during metro Atlanta's summer storm season. Combine that with the heavy rain, wind, and hail this area has seen recently, and roofs in Marietta age faster than homeowners expect.

What a Full Roof Replacement Should Include

A proper reroof isn't just new shingles. On this East Cobb project, our process includes:

• Complete tear-off down to the decking, never layering new shingles over old

• Full decking inspection and replacement of every compromised sheet

• New underlayment, drip edge, and flashing details

• Proper ventilation check so the new roof lasts its full lifespan

• Complete site protection and cleanup: tarps down, magnets through the yard, nothing left behind

Is It Repair or Replacement? Get an Honest Answer

Not every roof needs a full replacement. Last week we completed a targeted shingle repair on an Atlanta home for exactly that reason. But when a roof is at the end of its life, patching it is just delaying a bigger bill. The only way to know where your roof stands is a professional inspection, and ours are free.

If your Marietta or East Cobb home has an aging roof, visible wear, or storm exposure from this summer's weather, let's take a look before hidden damage gets worse. If storm damage is involved, many replacements are covered by insurance. Roofit Restoration handles the documentation and works with your carrier through the entire process.
