New Roof Leaks in Heavy Rain: Causes, Prevention, and Solutions
A new roof is supposed to protect your home, but sometimes even newly installed roofs can leak during heavy rain. Homeowners in Northeast Ohio, including Cleveland, Youngstown, Medina, Lakewood, Euclid, and surrounding areas, may encounter this frustrating issue. Understanding why leaks occur and how to prevent or repair them is critical.
At S&K Construction and Remodeling LLC, an Owens Corning Preferred Contractor headquartered in Jefferson, Ohio, we specialize in roofing inspection, repair, and installation. In this guide, we’ll examine common causes of leaks in new roofs and offer practical solutions.
1. Chimney Issues: Holes and Crown Problems
Chimneys are a frequent source of leaks, especially when the chimney crown or surrounding flashing is improperly installed. Key problems include:
- Holes or Cracks in the Crown: Water can penetrate through small cracks, seeping into the attic.
- Deteriorated Flashing: The metal barrier connecting the chimney to the roof may not be sealed properly.
- Missing Mortar or Gaps: Bricks can allow water to enter if mortar joints are damaged.
Prevention and Repair:
- Inspect and repair chimney crowns before roofing.
- Use high-quality flashing and sealants around chimneys.
- Regularly inspect chimneys for cracks and repair them promptly.
S&K Construction ensures all chimney penetrations are properly flashed and sealed to prevent leaks.
2. Pipe Boot Cracks in the Attic
Roof penetrations for plumbing vent pipes require pipe boots, usually made of rubber or flexible material. Common issues include:
- Cracks or Tears: Can develop during installation or from age.
- Improper Fit: Pipe boots that are too small or too large may allow water in.
- Debris Accumulation: Leaves or dirt can compromise seals.
Prevention and Repair:
- Inspect pipe boots during and after installation.
- Replace cracked or damaged boots immediately.
- Ensure proper flashing and sealant application.
A small crack in a pipe boot can cause significant water damage, so S&K Construction prioritizes inspection and correct installation.
3. Skylight Seal Failures
Skylights enhance natural light but are common leak points if not installed or sealed correctly. Typical issues include:
- Broken or Worn Seals: The rubber gasket or sealant around the skylight may fail.
- Improper Flashing: Skylights must have step flashing integrated with shingles.
- Roof Settlement: Slight movement of roof materials can compromise seals.
Prevention and Repair:
- Use high-quality skylight products with manufacturer-approved installation.
- Inspect seals annually, especially before rainy seasons.
- Replace damaged seals or flashing promptly.
S&K Construction ensures all skylights are properly flashed and sealed to withstand heavy rain.
4. Valleys with Exposed Nails
Roof valleys are channels where two roof planes meet and can be vulnerable to leaks, especially if nails are exposed. Issues include:
- Improper Nailing: Nails placed incorrectly can puncture underlayment or shingles.
- Lack of Protective Layer: Ice and water shield or underlayment may be missing in the valley.
- Debris Accumulation: Leaves and dirt can trap water, exacerbating leaks.
Prevention and Repair:
- Install ice and water shield along valleys.
- Ensure nails are correctly placed outside critical water paths.
- Clean valleys regularly to prevent water backup.
At S&K Construction, valley installation follows strict guidelines to prevent nail-related leaks.
5. Improper Seam Staggering or Bad Nail Placement
Shingle seams should be staggered correctly to prevent water infiltration. Common mistakes include:
- Aligned Seams: Creates continuous gaps that allow water penetration.
- Incorrect Nail Placement: Nails too high, low, or off-center can compromise waterproofing.
- Use of Wrong Shingle Type: Certain shingles require specific nailing patterns.
Prevention and Repair:
- Follow manufacturer nailing instructions carefully.
- Stagger seams properly to avoid continuous weak spots.
- Replace misaligned shingles during installation or early repair.
S&K Construction trains all installers on proper seam staggering and nailing techniques.
6. Seams Behind Chimneys or Around Roof Penetrations
Seams in vulnerable areas such as behind chimneys, vents, or dormers are prone to leaks if not sealed and flashed correctly. Issues include:
- Backside Water Flow: Water running down the roof may pool at seams.
- Insufficient Flashing: Lacking step or counter flashing creates gaps.
- Roof Deck Movement: Shifts can open previously sealed seams.
Prevention and Repair:
- Install proper step and counter flashing around chimneys and penetrations.
- Use sealants as needed to secure seams.
- Inspect seams after installation to verify integrity.
At S&K Construction, we pay special attention to these areas to prevent leaks from forming behind roof features.
7. The Role of Quality Materials
Even correctly installed roofs can fail if materials are subpar. Using high-quality shingles, flashing, underlayment, pipe boots, and skylight seals significantly reduces the likelihood of leaks.
- Shingles: Owens Corning Duration shingles provide durability and wind resistance.
- Underlayment: Synthetic underlayment resists tearing and water penetration.
- Flashing: Metal flashing that resists corrosion adds long-term protection.
S&K Construction uses only premium materials to maximize roof performance and warranty coverage.
8. Importance of Proper Installation
Leaks in new roofs often stem from installation errors rather than material defects. Key installation factors include:
- Correct nailing patterns
- Proper flashing integration
- Seam staggering
- Adequate underlayment coverage
- Ice guard installation along eaves and valleys
S&K Construction ensures every roof is installed according to manufacturer specifications and local building codes.
9. Inspection and Maintenance
Even new roofs benefit from periodic inspections, especially after heavy rain or storms. Homeowners should:
- Inspect attic ceilings for water stains
- Check around chimneys, skylights, and vents
- Examine valleys and seams for signs of water penetration
Early detection of leaks can prevent costly water damage to insulation, ceilings, and walls.
10. Safety Measures During Inspection and Repair
Safety is paramount. Roofers should follow OSHA guidelines, including:
- Fall protection systems and harnesses
- Scaffolding and ladders for safe access
- Clear communication and supervision on-site
S&K Construction prioritizes safety for both our crew and homeowners during inspections and repairs.
11. Insurance, Workman’s Compensation, and Permits
A professional roofing contractor should carry:
- Liability Insurance: Protects your home from accidental damage

- Permits: Ensures compliance with local building codes
S&K Construction handles all insurance verification and permitting, giving homeowners peace of mind.
