Leak Detection & Repair

The Leak You See Isn’t Where It Started

This is the most common misconception homeowners have about roof leaks. Water enters through a compromised point on the roof — a cracked flashing, a lifted shingle, a failed pipe boot — then travels along rafters, sheathing, and insulation before it finally appears as a stain on your ceiling. The entry point can be 10 or 20 feet from where the water shows up inside. That’s why patching the ceiling stain doesn’t fix anything, and why accurate leak detection matters more than fast repairs.

Vintage Roofing’s leak detection process is methodical. We trace the water path from the visible damage back to its entry point using a combination of interior inspection, attic examination, and systematic roof surface testing. We don’t guess — we find it.

Common Leak Sources

After 18 years of tracking down leaks across Georgia and Florida, we’ve found that the vast majority originate from a handful of vulnerable areas:

• Flashing failures — Step flashing along walls, counter-flashing at chimneys, and valley flashing are the most common leak sources. Sealant deteriorates, metal corrodes, and installation errors show up years later.
• Pipe boot deterioration — The rubber gaskets around plumbing vent pipes crack and split with UV exposure. This is the single most common source of slow leaks in Florida homes.
• Ridge cap and hip failures — Ridge caps take the most wind and UV exposure on the roof. Cracked or displaced ridge caps allow water directly into the attic.
• Nail pops and exposed fasteners — Thermal cycling causes nails to back out of decking over time, creating tiny openings that let water through during heavy rain.
• Skylight seals — The flashing and sealant around skylights are prone to failure, especially on south-facing slopes with maximum sun exposure.
• Ice dam remnants — In North Georgia, ice dams can force water under shingles and past the drip edge, causing leaks that only appear during freeze-thaw cycles.

Signs You May Have a Hidden Leak

Not every leak shows up as a ceiling drip. Watch for these warning signs that water may be infiltrating your roof system:

• Dark spots or discoloration on ceilings or upper walls
• Musty or moldy smell in the attic or upper floors
• Peeling paint or bubbling wallpaper near the roofline
• Unexplained increases in energy bills (wet insulation loses R-value)
• Visible mold or mildew growth in the attic
• Sagging or soft spots in the ceiling drywall

Our Repair Approach

Once we’ve identified the leak source, we repair it properly — not with a temporary seal or a tube of caulk. Depending on the issue, repairs may include replacing failed flashing with properly integrated new material, installing new pipe boots, replacing damaged shingles and underlayment, or re-sealing skylight perimeters. Every repair addresses the root cause so you don’t end up calling us back for the same problem.
