A leaky roof can be a homeowner’s nightmare, leading to water damage, mold growth, and structural issues. Fortunately, with the right approach and tools, you can tackle roof leaks effectively. Chris Feniello of Clearview Roofing and Construction will guide you through the repair process, focusing on common trouble spots such as valleys, chimneys, and skylights while emphasizing the importance of proper shingle replacement. Clearview Roofing has been in business since 1961 and is known as a local authority in roofing and repairs in the Long Island, NY area.
Identifying the Source of the Leak
Before repairing a leaky roof, identifying the source of the leak is the first and most crucial step, says Feniello. Locating the exact point of water infiltration is essential to avoid wasting time and materials. Leaks frequently occur near roof valleys—where two roof planes meet—and around chimneys and skylights, which are common failure points due to their protruding structures. Inspect these areas carefully, especially after a rainstorm, as water trails often reveal the problem area. Measuring the location of an interior leak can help pinpoint the source, and using a wall-scanning tool may be beneficial.
Most Common Leak-Prone Areas
1. Roof Valleys
Roof valleys are designed to channel water off the roof, but improper installation, lack of waterproofing, or debris buildup can lead to leaks. Inspect valleys for missing or damaged shingles. If the shingles appear intact, check for accumulated debris that may obstruct water flow. Clearing these areas may resolve minor leaks, but significant damage may require shingle replacement. Valleys are also prone to forming ice dams, which can further compromise the roof’s integrity.
2. Chimneys
Chimneys represent another common vulnerability. Check the flashing—metal strips that prevent water from seeping into the roof structure. If the flashing is rusted or cracked, replacement is necessary. Additionally, examine the mortar joints of the chimney. Any deterioration can allow water to penetrate, leading to extensive damage.
3. Skylights
Skylights can be a source of leaks, especially if they are poorly installed. Inspect the flashing around the skylight for lifting or damage. If gaps or cracks are visible, resealing with a high-quality roofing sealant may suffice—just be sure not to seal the bottom of the skylight flashing, as this can trap water and create leaks elsewhere. However, in most cases, proper repair involves removing and replacing surrounding shingles, inspecting the felt and ice-and-water shield, and ensuring correct waterproofing. Repairs for skylights can range from $700 to $1,000 due to labor, material costs, and company overhead. If a skylight needs replacement, costs can exceed $2,500, depending on the make and model.
The Importance of Removing and Replacing Shingles (Not Just Using Tar or Sealant)
When repairing a leaky roof, removing and replacing shingles is often necessary. Many homeowners attempt quick fixes, such as applying tar to leaks. While tar may offer temporary relief, it deteriorates over time, leading to recurring leaks. Instead, it’s critical to remove damaged shingles, inspect for underlying structural issues, and install new shingles correctly.
Steps to Replace Shingles Properly
- Safety First: Use a sturdy ladder and wear appropriate safety gear or a roofing harness.
- Remove Damaged Shingles: Carefully remove the affected shingles without damaging surrounding ones.
- Inspect Roof Decking: Check the underlying decking for rot or structural damage. Replace any compromised plywood sections.
- Apply Ice-and-Water Shield & Felt Paper: Proper waterproofing is essential to prevent future leaks, especially in high-risk areas.
- Install New Shingles: Follow manufacturer guidelines to lay new shingles, ensuring proper alignment and sealing against wind and rain.
- Install & Secure Flashing: Around valleys, chimneys, and skylights, ensure flashing is correctly installed. This process often requires expertise and specialized tools, such as a metal brake for custom-fitting flashing. If unfamiliar with the process, consider hiring a professional roofer.
Protecting Your Home from Future Leaks
Repairing a leaky roof requires careful inspection and a systematic approach, focusing on key areas such as valleys, chimneys, and skylights. While temporary fixes may provide short-term relief, addressing the root cause by replacing damaged shingles and ensuring proper flashing is essential for long-term protection. By following these steps, homeowners can safeguard their homes from water damage and extend the lifespan of their roofs.
