Common Causes of Eavestrough Overflow

Clogged Gutters

  • Debris Accumulation: Leaves, twigs, and other debris can accumulate in the eavestroughs, blocking the flow of water. When gutters are clogged, water overflows and spills over the sides.

  • Solution: Schedule regular gutter cleaning. Installing gutter guards can also help prevent debris from entering the gutters.


Improper Gutter Slope

  • Incorrect Installation: If the eavestroughs are not installed with the proper slope, water will not flow towards the downspouts efficiently, leading to overflow.

  • Solution: Professional gutter maintenance businesses can ensure a proper re-sloping, so that your gutters have a slight downward angle towards the downspouts.


Insufficient Gutter Size

  • Undersized Gutters: Gutters that are too small for the roof area they serve cannot handle the volume of water during heavy rain, resulting in overflow.

  • Solution: Upgrade to larger gutters, such as 6-inch gutters, to accommodate the increased water flow, especially in areas with heavy rainfall.


Blocked Downspouts

  • Obstructions: Downspouts can become blocked by debris, ice, or pests, preventing water from draining properly and causing the gutters to overflow.

  • Solution: Regularly inspect and clean the downspouts. Use a plumber’s snake or a high-pressure hose to clear any blockages.


Gutter Damage

  • Cracks and Holes: Damaged gutters with cracks or holes can lead to water leakage and overflow.

  • Solution: Small scale or large scale gutter repair can be used for small cracks and holes with a gutter sealant. For very extensive damage, consider replacing the affected sections of the gutter.


Heavy Rainfall

  • Extreme Weather: During heavy rainstorms, even properly functioning gutters can become overwhelmed and overflow.

  • Solution: Ensure your gutters are free of debris and functioning properly. Consider adding additional downspouts to help manage the increased water flow.


Effective Eavestrough Repair Methods

  • Tools Needed: Ladder, gloves, gutter scoop, garden hose.

  • Procedure: Safely position the ladder and use the gutter scoop to remove debris from the gutters. Rinse the gutters with a garden hose to ensure proper water flow.


  • Tools Needed: Ladder, screwdriver or drill, level.

  • Procedure: Loosen the gutter brackets and adjust the gutter’s position to achieve a slight downward slope towards the downspouts. Use a level to check the slope before securing the brackets.


Installing Gutter Guards

  • Tools Needed: Gutter guards, ladder, screwdriver or drill.

  • Procedure: Clean the gutters before installation. Attach the gutter guards according to the manufacturer’s instructions to prevent debris from entering the gutters.


Clearing Downspout Blockages

  • Tools Needed: Ladder, plumber’s snake or high-pressure hose.

  • Procedure: Remove the downspout from the gutter. Use the plumber’s snake or high-pressure hose to clear any blockages. Reattach the downspout and ensure proper water flow.


Repairing Cracks and Holes

  • Tools Needed: Ladder, gutter sealant, caulking gun.

  • Procedure: Clean the affected area and apply gutter sealant using a caulking gun. Allow the sealant to dry according to the manufacturer’s instructions before testing for leaks.


  • Tools Needed: New larger gutters, ladder, screwdriver or drill.

  • Procedure: Remove the old gutters and install the new, larger gutters. Ensure they are properly sloped and securely attached.


 

Eavestrough overflow can cause significant damage to your home if left unaddressed. By understanding the common causes and implementing the appropriate gutter repair methods, you can maintain an efficient gutter system and protect your home from water damage. Regular gutter maintenance, such as gutter cleaning and inspections, is key to preventing overflow and ensuring your eavestroughs function properly year-round.
