Autumn brings falling temperatures, heavier rainfall and plenty of leaves. While those leaves might look harmless on the ground, they can cause significant problems when they begin collecting on your roof and inside your guttering.
Blocked gutters, overflowing rainwater, damaged roof coverings and damp problems can all become more likely if leaves and debris are allowed to build up.
At JLC Roofing Co, we recommend keeping an eye on your roof and guttering throughout autumn, particularly if your property is surrounded by trees.
A little preventative maintenance now could help you avoid much bigger problems during winter.
Why Are Autumn Leaves a Problem for Your Roof?
Leaves rarely stay exactly where they land.
Wind can blow them across roofs and into gutters, valleys, drainage outlets and other areas where water needs to flow freely.
Once they become wet, leaves can stick together and form dense blockages.
Add twigs, moss and other debris and you can quickly have a drainage system that struggles to cope with heavy autumn rain.
The result can be water going somewhere it shouldn’t.
1. Leaves Can Block Your Gutters
This is one of the most common autumn roofing problems.
Your gutters are designed to collect rainwater from the roof and direct it towards the downpipes.
If the gutter becomes packed with leaves, water can’t flow away efficiently.
During heavy rainfall, you may notice water pouring over the side of the gutter instead.
A small amount of debris might not seem serious during light rain, but a blocked gutter can become much more obvious during an autumn downpour.
2. Blocked Downpipes Can Cause Water to Back Up
The gutter itself isn’t the only area that can become blocked.
Leaves and smaller pieces of debris can enter the downpipe.
If a blockage develops, water can back up into the gutter even if the visible section appears relatively clear.
Signs of a blocked downpipe can include overflowing gutters, slow drainage and water escaping around joints.
If you’ve cleaned the gutter but water still isn’t draining correctly, the downpipe may also need attention.
3. Overflowing Water Can Affect Your Walls
When rainwater repeatedly pours over the edge of a blocked gutter, it can run directly down the exterior of your property.
Over time, this may contribute to staining and persistent moisture around external walls.
If there are existing defects in pointing, render or other parts of the building, repeated exposure to water can make matters worse.
Your guttering is there to move water safely away from the property.
Keeping it clear helps it do that job properly.
4. Leaves Can Collect in Roof Valleys
Roof valleys are another area where autumn debris can accumulate.
A valley is designed to channel significant amounts of rainwater from adjoining roof slopes.
Leaves, moss and twigs can restrict this flow.
If water can’t drain properly, it may back up or find its way beneath damaged or poorly maintained roof coverings.
Because valleys handle so much water during heavy rain, problems in these areas shouldn’t be ignored.
5. Debris Can Hide Damaged Roof Tiles
A collection of leaves and debris can make it harder to see what’s happening underneath.
There could be cracked, slipped or missing tiles hidden below accumulated material.
After strong autumn winds, it’s worth visually checking the roof from ground level for obvious changes.
Never climb onto a roof yourself to investigate.
Roof work can be dangerous, particularly during wet and windy autumn weather.
If you suspect a problem, arrange a professional inspection.
6. Moss Can Make the Problem Worse
Leaves aren’t always acting alone.
Many roofs already have areas of moss, particularly where sections receive limited sunlight.
Loose moss can fall into gutters and combine with leaves to create substantial blockages.
Wet organic debris can become heavy, putting additional strain on guttering and brackets.
If your gutters regularly become blocked, it may be worth investigating where the debris is coming from rather than repeatedly dealing with the overflow.
7. Standing Water Can Put Pressure on Guttering
Gutters aren’t designed to permanently hold large amounts of standing water and saturated debris.
When outlets are blocked, the additional weight can place pressure on gutter brackets and joints.
You may eventually notice sections beginning to sag or pull away.
Once a gutter loses its correct alignment, it may no longer drain effectively even after the blockage is removed.
This can turn what started as a simple cleaning job into a gutter repair.
8. Water Can Freeze During Colder Weather
Autumn quickly turns into winter.
If blocked gutters contain standing water when temperatures fall below freezing, that water can freeze.
This creates additional weight and can place further strain on already weakened guttering.
Clearing problems before the coldest weather arrives is therefore much better than waiting until the middle of winter.
9. Blocked Guttering Can Contribute to Damp Problems
If water repeatedly overflows close to walls, windows or roof junctions, you may eventually begin noticing signs of moisture inside the property.
Not every damp patch is caused by a blocked gutter, but external drainage should certainly be investigated when diagnosing water ingress.
If you’ve noticed a damp patch appearing after heavy rain, look outside from ground level.
Is the gutter overflowing? Is water running down the wall? Is there an obvious roofing problem above the affected area?
These clues can help identify where further investigation is required.
10. Autumn Storms Can Make Existing Problems Worse
Autumn doesn’t only bring falling leaves.
Strong winds and heavy rain can expose existing weaknesses in your roof.
A tile that was already slightly loose may move. Ageing gutter brackets may struggle under the weight of wet debris. A small leak may suddenly become much more noticeable during prolonged rainfall.
This is why autumn is such an important time to pay attention to the condition of your roof.
Warning Signs Your Gutters Need Attention
You don’t always need to see inside the gutter to know there’s a problem.
Look out for:
- Water overflowing during rainfall
- Plants or weeds growing from gutters
- Sagging gutter sections
- Water running down external walls
- Staining beneath guttering
- Leaking gutter joints
- Downpipes that aren’t draining properly
- Damp patches appearing after heavy rain
If you notice these signs, it’s worth getting the problem investigated before winter.
Check Your Roof Before Winter
Autumn is an ideal time to identify minor roof defects before harsher winter weather arrives.
A professional roof inspection can look for problems such as slipped or damaged tiles, deteriorated pointing, defective flashing, damaged guttering and other areas that may allow water into the property.
Dealing with a small repair early can often prevent further damage.
Ignoring a roofing problem throughout a wet winter can allow water ingress to affect timbers, insulation, plaster and internal decoration.
How Often Should Gutters Be Checked?
There’s no single schedule that’s appropriate for every property.
A house surrounded by mature trees may need its guttering checked more frequently than a property in a more open location.
Autumn is an obvious time to pay particular attention because of the volume of falling leaves.
It can also be sensible to check again once most leaves have fallen, particularly before winter weather becomes established.
Don’t Take Unnecessary Risks
Cleaning guttering or inspecting a roof can involve working at height.
If you can’t safely access an area, don’t take unnecessary risks with ladders or attempt to walk across the roof.
Professional roofers have the appropriate equipment and experience to investigate roofing and guttering problems safely.
Sometimes the safest solution is simply to call someone who deals with these issues every day.
