🔍Introduction
In this article, we will be embarking on a live walk-over inspection of a roof with a leaking chimney. The roof, which is about three years old, has been experiencing issues with water infiltration around the chimney. The homeowners contacted the contractor, only to be informed that the warranty had expired. With the homeowners absent during the inspection, we have the opportunity to analyze the problematic areas and provide recommendations for repairs.
🏠Roof Inspection: The Leaking Chimney
As we begin our inspection, we notice a corner of the roof that catches our attention. This area, where the flashing should extend or have a corner-style flashing, is instead vulnerable to water penetration. Although the roof has a decent overhang, this gap in the flashing becomes problematic when facing strong southerly winds or heavy rainfalls. Water can easily find its way into the exposed opening, exacerbating the leak near the exterior wall. This highlights the importance of proper corner flashing, especially in re-roofing projects with fragile materials like cedar siding.
🏗Understanding Wall Flashing
Wall flashing plays a crucial role in diverting water away from vulnerable areas, such as chimneys. The concept of extending or bending the flashing is often misunderstood or overlooked in re-roofing projects. Rather than simply placing a piece of flashing flush against the wall, creating a small lip that directs water onto the shingles is ideal. This simple technique can significantly prevent water from entering gaps or holes, enhancing the overall waterproofing of the roof.
🖇The Importance of Corner Flashing
When it comes to corner flashing, it becomes even more vital to ensure proper installation. Many contractors tend to neglect corner flashing in re-roofing projects, assuming that the existing flashing will suffice. However, this can lead to potential leaks and water damage. Extending the flashing around corners and bends provides an additional layer of protection against water intrusion. In the case of our inspection, the lack of corner flashing on both chimneys contributes to their current leakage issues.
❌Issues with the Existing Flashing
Upon closer examination, we discovered that the existing flashing around the first chimney had been removed. Instead of installing new flashing, a thin layer of silicone caulking was applied to the wall as a temporary solution. This makeshift fix is insufficient and does not provide the necessary protection against water infiltration. Similarly, the second chimney also lacked proper flashing, resorting to old tar and fiber with additional caulking. Identifying these issues is crucial in developing effective repair strategies.
🏚Examining the First Chimney
Moving on to the first chimney, it becomes apparent that the absence of flashing is a recurring issue. The rusted steel and deteriorated wood further indicate neglect in maintenance and proper roofing practices. Due to the absence of flashing, rainwater easily finds its way into cracks and openings, potentially causing internal damage to the structure. Taking note of the severity of the situation, immediate action is required to rectify the problem.
🔍Identifying Problems with the First Chimney
The major problem with the first chimney lies in the complete lack of flashing. By relying solely on caulking and tar, this approach fails to provide adequate protection against water intrusion. Furthermore, deteriorated shingles and the absence of step flashing worsen the situation, leaving the wood susceptible to rot and decay. Understanding the root causes of the leak is imperative in developing a comprehensive solution.
💡Recommended Solutions for the First Chimney
To address the issues with the first chimney, a complete reflash is necessary. This involves removing the damaged shingles, installing new step flashing on all sides of the chimney, and placing a piece of coil stock at the bottom to ensure proper water diversion. Additionally, grinding a channel into the brick and incorporating aluminum counter flashing will further enhance the waterproofing. Finally, caulking around the top will provide an added layer of protection, effectively resolving the leakage problem.
🏠Analyzing the Second Chimney
Upon approaching the second chimney, a striking similarity to the first becomes apparent. Once again, the absence of flashing is evident, leaving the wood susceptible to water damage. The reliance on old tar and a minimal application of caulking only serves as a temporary fix, failing to address the root cause of the leak. Given the proximity of the two chimneys, it is highly likely that the second chimney is also experiencing leakage issues.
🔍Identifying Problems with the Second Chimney
Similar to the first chimney, the second chimney suffers from the lack of flashing. The absence of appropriate flashing allows rainwater to seep into the cracks and gaps, compromising the structural integrity of the wood. The absence of preventive measures, such as step flashing, exacerbates the issue and poses a serious problem. Immediate action is needed to rectify the situation before further damage occurs.
💡Recommended Solutions for the Second Chimney
To address the leakage issues with the second chimney, a comprehensive reflash is crucial. Similar to the first chimney, the solution involves removing the existing tar and fiber, installing proper step flashing, and incorporating coil stock at the bottom. Grinding a channel into the brick and implementing aluminum counter flashing will effectively prevent water penetration. By applying these solutions, the second chimney can regain its functionality and ensure long-term protection against leaks.
🏢Contractor Warranties: What to Consider
When it comes to roofing projects, it's essential to consider the warranties offered by contractors. The duration of the warranty often reflects the contractor's confidence in their workmanship. It's vital to communicate with contractors and inquire about the warranty they provide. Typically, reputable contractors offer warranties ranging from three years to a lifetime. Understanding the warranty terms and conditions is essential to ensure proper coverage and satisfaction as a homeowner.
💰Factors Affecting Pricing in the Roofing Market
Pricing in the roofing market can vary significantly depending on various factors. Labor costs, materials used, market demand, and local competition all play a role in determining the final price for roofing projects. Reputable contractors usually have a minimum labor cost and a standard rate for materials. However, some contractors may offer lower prices by compromising on the quality of materials or workmanship. Homeowners should carefully evaluate the factors affecting pricing and choose a contractor that provides a fair balance between cost and quality.
🏁Conclusion
In conclusion, our live walk-over inspection revealed significant issues with the flashing and waterproofing of the chimney on a three-year-old roof. The absence of proper flashing and reliance on temporary fixes, such as caulking and tar, contributed to the leakage problems. Through a thorough examination, we identified the root causes of the leaks and provided recommended solutions for effective repairs. It's essential for homeowners and contractors to prioritize proper flashing techniques and consider long-term warranties to ensure the durability and functionality of roofs.
