Why Gaps Between Gutters and Roofs Are a Problem
Gaps between your gutter and roof can lead to serious water damage if left unaddressed. When rainwater bypasses your gutters and flows behind them, it can cause fascia board rot, soffit damage, foundation issues, and basement flooding.
Common Causes of Gutter Gaps
1. Improper Installation
The most common cause of gutter gaps is improper installation:
- Gutters mounted too low on the fascia
- Incorrect pitch or slope
- Missing or inadequate hangers
- Wrong size gutters for roof area
2. Age and Wear
Over time, gutters naturally develop gaps due to:
- Expansion and contraction from temperature changes
- Weight of debris and ice pulling gutters down
- Loosening of screws and hangers
- Wood fascia shrinkage or rot
3. Storm Damage
Severe weather can create or worsen gaps:
- Heavy ice or snow loads
- Strong winds
- Falling branches
- Hail damage
4. Sagging Fascia
When the fascia board becomes damaged or waterlogged, it can sag and pull the gutters away from the roof edge.
Techniques to Fix Gutter Gaps
Technique 1: Gutter Apron Installation
A gutter apron (also called a drip edge extension) is one of the most effective solutions:
- Metal flashing that slides under shingles
- Extends over the back edge of the gutter
- Directs water into the gutter, not behind it
- Available in aluminum, galvanized steel, or copper
Installation steps:
- Carefully lift roof shingles at the edge
- Slide the apron under the shingles
- Bend the bottom lip into the gutter
- Secure with roofing nails or sealant
Technique 2: Drip Edge Repair or Replacement
If your drip edge is damaged, missing, or improperly installed:
- Remove damaged sections carefully
- Install new drip edge under the roofing felt
- Ensure it extends over the gutter back edge
- Seal any seams with roofing sealant
Technique 3: Gutter Repositioning
Sometimes the solution is simply repositioning your gutters:
- Loosen the existing hangers
- Raise the gutter to close the gap
- Ensure proper slope toward downspouts (1/4 inch per 10 feet)
- Re-secure with appropriate screws or hangers
Technique 4: Fascia Board Repair
If the fascia is the problem:
- Remove gutters temporarily
- Replace rotted or damaged fascia sections
- Install fascia cover or wrap for protection
- Reinstall gutters at proper height
Technique 5: Splash Guards
For gaps that occur at corners or valleys:
- Install splash guards at problem areas
- Direct concentrated water flow into gutters
- Available in various materials and sizes
