If you own a home in Georgia, you already know that the weather here doesn’t play around. From heavy spring rainstorms to scorching summer heat and the occasional winter freeze, Georgia’s climate puts your roof through a lot every single year. One of the most overlooked \u2014 yet most critical \u2014 parts of any roofing system is the flashing. When roof flashing fails, water finds its way inside your home faster than you might expect. Understanding why flashing fails and what causes leaks is the first step toward protecting your investment.<\/p>\n
At goingwithgibbs<\/a><\/strong>, we’ve helped hundreds of Georgia homeowners identify and repair flashing problems before they turn into expensive structural disasters. In this blog, we’ll walk you through the top causes of roof flashing failures specific to the Georgia region and what you can do about them.<\/p>\n Roof flashing is thin metal material \u2014 typically made from galvanized steel, aluminum, or copper \u2014 installed at the joints, edges, and transitions of a roof. Its job is simple but vital: redirect water away from vulnerable areas where two roof surfaces meet or where the roof connects to vertical structures like chimneys, skylights, vents, and walls.<\/p>\n When flashing works properly, rainwater flows smoothly off the roof and into gutters. When it fails, water seeps into the underlayment, decking, insulation, and eventually your ceilings and walls. In Georgia, where annual rainfall averages over 50 inches in many areas, a small flashing failure can quickly become a major leak.<\/p>\n The number one cause of flashing failure across Georgia homes is improper installation. Flashing requires precision \u2014 it must be cut, bent, and sealed correctly to form a watertight barrier. Many homeowners attempt DIY repairs or hire inexperienced contractors who skip critical steps, such as overlapping sections properly, using the right fasteners, or applying compatible sealant.<\/p>\n Incorrectly installed step flashing around dormers, chimneys, or skylights allows water to run behind the metal rather than over it. If your flashing was installed by someone who wasn’t specifically trained in roofing, there’s a strong chance it’s only a matter of time before it fails.<\/p>\n Choosing a trusted roofing contractor in Georgia<\/a><\/strong> with demonstrated expertise in flashing installation is the single best thing you can do to prevent this problem from the start.<\/p>\n Georgia’s climate is uniquely brutal on roofing materials. Summers push temperatures above 90\u00b0F for weeks at a time, while winters can bring freezing temperatures and ice. This constant thermal expansion and contraction causes metal flashing to shift, pull away from sealed joints, and crack over time.<\/p>\n In North Georgia especially, freeze-thaw cycles are a serious concern. Water trapped near flashing joints freezes overnight, expands, and forces the metal out of position. By spring, those gaps become entry points for every rain event that follows. This is a weathering process that compounds silently over years, and most homeowners don’t notice until the damage is already visible on interior ceilings.<\/p>\n According to the National Roofing Contractors Association (NRCA)<\/a><\/strong>, thermal movement is one of the leading causes of flashing degradation, particularly in climates with significant temperature variation like the southeastern United States.<\/p>\n Even well-installed flashing won’t last forever. Galvanized steel flashing typically lasts 20 to 30 years, while aluminum can degrade faster when exposed to certain chemicals found in roofing materials or local water chemistry. In Georgia’s humid subtropical climate, moisture is almost always present \u2014 and that moisture accelerates rust and corrosion.<\/p>\n When flashing begins to corrode, pinhole leaks form first. These tiny holes are nearly invisible from the ground but allow water to drip steadily into your attic or wall cavities. Over time, corrosion spreads, the metal weakens, and sections begin to lift or separate entirely.<\/p>\n If your home is more than 15 years old and the flashing has never been inspected or replaced, it’s likely past its prime. Schedule a professional roof inspection at goingwithgibbs<\/a><\/strong> to assess the current condition of your flashing before the next Georgia rainy season arrives.<\/p>\n Most flashing installations rely on roofing sealant or caulk to fill gaps and create a watertight seal around edges and penetrations. Unfortunately, sealant doesn’t last as long as metal flashing does. In Georgia’s heat, standard caulk dries out, shrinks, and cracks within just a few years of application.<\/p>\n Once the sealant fails, water can seep between the flashing and the roofing surface, especially during heavy rain driven by wind \u2014 which is extremely common during Georgia’s afternoon thunderstorms and tropical weather systems.<\/p>\n Many homeowners mistakenly believe that simply reapplying caulk over old, cracked sealant will fix the problem. It won’t. The old material needs to be fully removed, the surface cleaned, and a compatible, weather-grade sealant applied correctly. This is a repair that should always be done by a professional roofer who understands the materials involved.<\/p>\n Roof flashing doesn’t exist in isolation \u2014 it works as part of your entire roofing drainage system. When gutters become clogged with leaves, pine needles, or debris (a very common issue in Georgia’s tree-rich neighborhoods), water backs up along the roofline and sits directly against flashing joints.<\/p>\n This standing water dramatically increases the chance of water intrusion. It also keeps flashing materials persistently wet, which speeds up corrosion and causes sealant to break down faster. Regular gutter cleaning \u2014 at least twice a year in Georgia, and more often if you have large trees nearby \u2014 is one of the simplest ways to extend the life of your flashing.<\/p>\n If you’ve been skipping gutter maintenance, there’s a good chance your flashing has already been stressed by water backup. A professional roof inspection can tell you exactly how much damage has occurred.<\/p>\n Two of the most leak-prone areas on any Georgia roof are around chimneys and skylights. These features require multiple pieces of flashing \u2014 counter flashing, step flashing, and saddle flashing \u2014 all working together. Any gap in this system creates a direct pathway for water.<\/p>\n Georgia homes with older chimneys often suffer from mortar deterioration and brick movement that pulls counter flashing away from the chimney wall. Skylights, particularly those installed more than 10 years ago, frequently develop leaks because the original flashing kits weren’t designed to handle long-term exposure to Georgia’s heat and UV radiation.<\/p>\n The Environmental Protection Agency (EPA)<\/a><\/strong> notes that water intrusion from roof failures is one of the leading contributors to indoor mold growth \u2014 a significant health concern that’s particularly relevant in humid Georgia climates. Chimney and skylight leaks left unaddressed almost always result in mold in the attic or wall cavities.<\/p>\n Georgia sits in a region prone to severe thunderstorms, tropical storm remnants, and occasional tornadoes. High winds can lift flashing edges that have even slightly loosened over time, bending or tearing the metal away from its sealed position.<\/p>\n After any significant storm event, it’s wise to have your roof inspected even if you don’t notice obvious damage from the ground. Flashing that has been partially lifted by wind may look fine from below but allow water to enter during the next rain event.<\/p>\n Contact the team at goingwithgibbs<\/a><\/strong> for post-storm roof inspections across the Georgia area. Catching wind damage to flashing early can save you thousands in water damage repairs.<\/p>\n Prevention always costs less than repair. Here are the most effective steps Georgia homeowners can take to prevent flashing failures:<\/p>\n A: Common signs include water stains on interior ceilings or walls, visible rust or gaps around your chimney or skylight, and peeling paint near roof edges. If you notice any of these signs, schedule an inspection immediately.<\/p>\n A: Depending on the material, flashing typically lasts 15 to 30 years. However, Georgia’s heat, humidity, and storm activity can shorten that lifespan, especially if the flashing wasn’t installed correctly.<\/p>\n A: Minor sealant touch-ups may be manageable for experienced DIYers, but full flashing repair or replacement should always be done by a licensed roofing professional to ensure a proper, watertight result.<\/p>\n A: Costs vary depending on the location and extent of damage. Small repairs typically range from $150 to $400, while full chimney or skylight reflashing can cost $500 to $1,500 or more. Catching problems early keeps costs down significantly.<\/p>\n A: It depends on the cause. Storm-related flashing damage is often covered, while deterioration from age or neglect typically is not. Review your policy carefully and document damage with photos before filing a claim.<\/p>\n Roof flashing is a small component with a big job \u2014 and in Georgia’s demanding climate, it takes real punishment year after year. Whether your home is dealing with an active leak or you simply want to get ahead of potential problems, the experienced team at goingwithgibbs \u00a0<\/a><\/strong>is ready to help. Don’t wait for a ceiling stain to tell you something’s wrong. Protect your home now with a professional flashing inspection and keep Georgia’s unpredictable weather where it belongs \u2014 outside.<\/p>\nWhat Is Roof Flashing and Why Does It Matter?<\/h2>\n
