SeaTac Skylights Facing the Fury of Hail Repairing Damaged Flashing
SeaTac, Washington, a region known for its frequent rainfall, also experiences significant hailstorms, particularly during the spring and summer months. These frozen projectiles can inflict considerable damage on residential and commercial properties, and one often overlooked but critical area affected is the flashing around skylights. Properly functioning flashing is essential for preventing water intrusion, and when compromised by hail, it becomes a porous gateway for leaks, potentially leading to extensive structural damage, mold growth, and compromised indoor air quality. This article delves into the intricacies of repairing hail-damaged flashing around skylights in SeaTac, outlining the common issues, the repair process, and why prompt action is paramount.
Understanding Hail Damage to Skylight Flashing
Hailstones, depending on their size and the intensity of the storm, can strike skylight flashing with considerable force. The flashing, typically made of metal like aluminum, copper, or galvanized steel, is designed to create a watertight seal between the skylight unit and the roof. Hail can cause several types of damage to this crucial component:
Dents and Punctures: Even small hailstones can create noticeable dents in the metal flashing. Larger hailstones, however, can cause significant punctures, creating direct openings for water to enter the attic and interior spaces. These punctures can be jagged and irregular, making them difficult to seal effectively without proper repair.
Cracks and Warping: The impact of hail can cause the metal to crack, especially at seams and corners where stress is concentrated. Intense impacts can also lead to warping of the flashing, compromising its ability to maintain a tight seal against the roof. Warped flashing may lift away from the roof surface, creating gaps that water can exploit.
Loosened Fasteners: Hailstorms can shake and vibrate the entire roof structure. This can lead to the loosening or even popping out of the screws or nails that secure the flashing to the roof deck and skylight frame. Once fasteners are compromised, the flashing can shift, creating pathways for water ingress.
Sealant Degradation: While not directly damaged by hail, the sealants used to further waterproof the flashing can be stressed and cracked by the impacts and subsequent movement of the flashing. This can lead to a breakdown in the protective barrier.
The Importance of Timely Repair
The damage caused by hail to skylight flashing may not always manifest as an immediate, obvious leak. However, even minor breaches in the flashing can lead to a cascade of problems over time. Moisture that enters the attic can saturate insulation, reducing its effectiveness and potentially causing it to sag. This moisture can also condense on wooden structural components, leading to rot and decay. Furthermore, persistent dampness creates an ideal breeding ground for mold and mildew, which pose significant health risks, particularly for individuals with respiratory conditions. Therefore, addressing hail damage to skylight flashing promptly is not merely about preventing immediate leaks but also about safeguarding the long-term integrity and health of the property.
The Professional Repair Process for Hail-Damaged Flashing
Repairing hail-damaged skylight flashing in SeaTac requires a systematic approach executed by experienced roofing professionals. Here’s a breakdown of the typical process:
Inspection and Assessment
The first and most crucial step is a thorough inspection by a qualified roofing contractor. They will meticulously examine the entire skylight unit, paying close attention to the flashing around its perimeter. This involves:
Visual Inspection: Identifying visible dents, punctures, cracks, and areas where the flashing has pulled away from the roof. They will also look for signs of sealant failure.
Water Testing: In some cases, a controlled water test may be conducted to pinpoint the exact location of leaks, especially if the damage is not immediately apparent.
Drone or Aerial Inspection: For hard-to-reach areas or extensive roof systems, drones might be utilized to get a closer look at the flashing without risking further damage.
Damage Documentation: The contractor will document all findings, often with photographs, to provide to the homeowner and potentially for insurance claims.
Preparation and Cleaning
Before any repairs can commence, the damaged area must be thoroughly cleaned. This involves removing any debris, loose gravel, or old sealant that might interfere with the new sealing. The metal flashing itself will be cleaned to ensure proper adhesion of any repair materials.
Repair Techniques
The specific repair technique will depend on the severity and type of hail damage:
Minor Dents and Punctures: For small dents, a skilled roofer may be able to carefully hammer them out, ensuring the metal is smoothed to create a proper seal. For small punctures, specialized roofing sealants and patches may be applied. These patches are durable and designed to withstand the elements. The application typically involves cleaning the area, applying a high-quality roofing sealant, and then embedding a piece of compatible flashing material or a specialized repair tape over the puncture. This is then sealed around the edges.
Cracks and Larger Punctures: Larger cracks or more significant punctures often require replacement of damaged flashing sections. This involves carefully removing the compromised metal, ensuring the underlying roofing material is intact, and then installing new flashing that perfectly matches the original profile and material. New flashing is typically integrated with the existing roofing layers and sealed to create a watertight barrier. This often involves lifting shingles or other roofing materials to adequately secure and seal the new flashing.
Warped Flashing: Severely warped flashing usually needs to be replaced. The process is similar to repairing cracks, involving removal of the old material and installation of new, properly shaped flashing.
Loosened Fasteners: If fasteners have loosened, they will be replaced with new, appropriately sized roofing screws equipped with sealant washers. The flashing will be secured firmly to the roof deck, ensuring no gaps are created.
Sealing and Waterproofing
Once the structural integrity of the flashing is restored, the next critical step is comprehensive sealing. High-quality, weather-resistant roofing sealants are applied along all seams, edges, and any areas where repair patches have been installed. These sealants are designed to remain flexible and withstand extreme temperature fluctuations and UV exposure, which are common in the Pacific Northwest.
Testing and Final Inspection
After the repairs are complete and the sealants have cured, a final inspection is conducted. This may include another water test to confirm that all potential leak points have been effectively sealed. The roofer will ensure that the new flashing integrates seamlessly with the existing roofing system and that no aesthetic compromises have been made.
Choosing the Right Professional in SeaTac
When selecting a contractor for skylight flashing repair in SeaTac, several factors are essential:
Experience: Look for contractors with specific experience in skylight repairs and hail damage restoration. Ask about their familiarity with SeaTac’s common weather patterns.
Licensing and Insurance: Ensure the contractor is properly licensed and insured. This protects you in case of accidents or unforeseen issues during the repair process.
Reputation and Reviews: Check online reviews and ask for references from past clients. A good reputation is a strong indicator of quality workmanship.
Warranty: Inquire about warranties on both the materials used and the labor. A reputable contractor will stand behind their work.
Written Estimates: Always obtain a detailed, written estimate that clearly outlines the scope of work, materials to be used, and cost breakdown.
Conclusion
Hail damage to skylight flashing in SeaTac is a common but serious issue that demands prompt and professional attention. Ignoring these damages can lead to escalating repair costs, health concerns related to mold, and compromised structural integrity of the property. By understanding the nature of hail damage and adhering to the meticulous repair process undertaken by experienced roofing professionals, homeowners and property managers can effectively protect their investments from the persistent threat of water intrusion, ensuring their skylights continue to function as intended – letting in light, not leaks.
