Slate roofing is a premium choice for homeowners who value longevity, durability, and timeless beauty. In Atlanta, GA, where the climate can range from hot, humid summers to stormy transitional seasons, slate roofs are a popular solution for those looking to invest in a long-lasting roofing system.

However, even the most resilient slate roof is not immune to problems over time. Weather exposure, installation issues, and natural aging can lead to repair needs that, if left unaddressed, compromise the roof’s performance and lifespan. Understanding the most common issues—and how to fix them—can help homeowners protect their investment.

Braswell Construction Group, a well-regarded slate roofing contractor in Atlanta, GA, shares insight into the top slate roofing problems homeowners should watch for, along with trusted solutions.

1. Broken or Cracked Slate Tiles

One of the more common issues with slate roofing is cracked or broken tiles. These often occur due to foot traffic during maintenance, impact from falling limbs, or aging materials. In Atlanta, temperature fluctuations can also cause expansion and contraction, leading to cracks.

While it may seem minor, even a single broken tile can allow water to seep underneath, eventually leading to leaks and damage to the roof deck.

How to fix it: It’s recommended that a professional slate roofer in Atlanta, GA carefully remove the damaged tile and replace it using the correct tools and fastening techniques. It’s important to avoid temporary solutions like tar or sealant, which can trap moisture and worsen the problem over time.

2. Missing Tiles After Severe Weather

Atlanta storms can bring high winds and heavy rain, occasionally dislodging slate tiles—especially if they were not properly installed or have weakened over time. Missing tiles can expose the underlayment and allow moisture intrusion, quickly escalating into more serious damage.

How to fix it: Replacing missing tiles promptly is key. Braswell Construction Group ensures new tiles match the existing roof in size, thickness, and color to preserve the aesthetic while restoring functionality.

3. Deteriorating Flashing Around Vents and Chimneys

Flashing is a critical component of any slate roof system. It seals areas where the roof intersects with chimneys, skylights, or dormers. Over time, flashing made of metal can corrode or loosen due to age or improper installation. In Atlanta’s humid climate, flashing failures are a common cause of roof leaks.

How to fix it: Flashing should be replaced with high-quality materials like copper or stainless steel. A slate roofing contractor in Atlanta, GA will ensure all flashing is properly integrated into the roof system and sealed to prevent future leaks.

4. Improper Repairs from Previous Contractors

Slate roofing is a specialty trade. Unfortunately, not all roofers are trained to handle it. Some homeowners discover problems stemming from previous repairs made with asphalt shingles, caulk, or other materials that are incompatible with slate.

These improper fixes can cause further cracking, introduce moisture, and shorten the roof’s lifespan.

How to fix it: Braswell Construction Group often begins repairs by carefully removing past patchwork and restoring the slate system using traditional methods and proper materials. Getting the job done right the first time avoids repeat repairs and damage.

5. Moss and Algae Growth in Humid Areas

Atlanta’s humid weather can lead to moss and algae growth on slate roofs, particularly in shaded areas. While slate itself is resistant to moisture, organic buildup can trap water and eventually lead to deterioration of fasteners or encourage debris accumulation.

How to fix it: A gentle cleaning using a soft brush and water can remove moss without damaging the tiles. For persistent growth, a professional treatment plan can be put in place. Braswell Construction Group offers maintenance services to address this without causing harm to the roofing material.

6. Slipping or Loose Tiles

Slate tiles are individually fastened, and over time, those fasteners can corrode or loosen. This can cause tiles to shift out of place or slide off the roof, particularly after strong storms or high winds.

How to fix it: A professional slate roofer will assess the underlying fasteners and replace or re-secure the affected tiles. It’s also an opportunity to inspect nearby slates for early signs of similar issues.

7. Water Stains or Interior Leaks

Any time water begins to show up inside the home, the roof should be the first place to inspect. Water stains on ceilings or walls are often a sign of either flashing failure or compromised slate.

How to fix it: A detailed inspection by a trusted slate roofing contractor in Atlanta, GA will pinpoint the source of the leak. Whether it’s a flashing issue or broken tiles, the repair must restore the full waterproofing integrity of the roof system.
