Introduction
A properly functioning guttering system is crucial to protecting your home from water damage, damp, and structural issues. Poor drainage doesn’t just affect your roofline—it can lead to costly repairs to your walls, foundations, and even interiors. At Erith Roofing Repairs, we’ve worked with property owners throughout Erith, Greater London to optimise gutter systems that enhance drainage, extend roof lifespan, and preserve overall building integrity.
Whether you’re dealing with overflowing gutters or water pooling near your foundation, this guide outlines five effective ways to improve drainage with the right guttering upgrades and maintenance practices.
1. Install Larger Capacity Guttering
Not all guttering systems are created equal. In areas with high rainfall, standard-size gutters may simply not be up to the task, especially on larger roofs.
Why size matters:
- Greater water flow capacity during heavy storms
- Reduced risk of overflow and associated wall staining
- Better performance on steep or expansive roof surfaces
Consider upgrading to deep flow or half-round gutters to better handle peak rainfall, particularly in exposed areas of Erith, Greater London.
2. Ensure Correct Gutter Slope and Alignment
If your gutter system isn’t properly sloped, water will sit rather than flow—leading to standing water, sagging, and eventual leaks.
Key checks for alignment:
- Gutters should slope 1cm every 3m towards the downpipe
- No sections should be completely level or bowed
- Downpipes should be placed at natural collection points
At Erith Roofing Repairs, we assess and adjust your system to ensure proper fall and optimal flow across the entire length.
3. Clear Blockages and Maintain Clean Gutters
Leaves, moss, and other debris can quickly clog gutters and downpipes, reducing their effectiveness and causing overflows that damage facades and soak brickwork.
Maintenance tips:
- Clean gutters at least twice a year—spring and autumn
- Fit leaf guards or gutter brushes to prevent future build-up
- Inspect downpipes for clogs or slow flow after rainfall
Regular maintenance is a simple but highly effective way to keep your drainage system performing as it should.
4. Add More Downpipes Where Needed
One downpipe is often not enough, especially on long runs of guttering. If water backs up during rainstorms, additional outlets may be required to improve efficiency.
Benefits of multiple downpipes:
- Even distribution of water flow
- Less stress on individual downpipe connections
- Faster drainage away from roof and foundation areas
We recommend assessing how water flows during rainfall and identifying any overflow points that could benefit from an additional downpipe.
5. Direct Water Away from Foundations
It’s not just about getting water off the roof—it’s also about ensuring it moves safely away from the building. Downpipes that discharge close to walls can cause waterlogging, damp, and even foundation issues.
Drainage improvement ideas:
- Attach downpipes to soakaway systems
- Extend downpipe outlets using drainage channels
- Install water butts to collect and store rainwater sustainably
At Erith Roofing Repairs, we can advise on suitable drainage extensions that work with the layout of your property in Erith, Greater London.
