Flat roofs are a popular choice for many homes and commercial buildings in the UK, especially in areas like Kent where modern extensions and low-pitch designs are common.
While flat roofs can be cheaper and easier to build compared to pitched roofs, they tend to need a little extra care to avoid early wear and tear.
The good news is that with regular maintenance and a few proactive measures, you can significantly extend the lifespan of your flat roof. Here are 7 practical tips to help you get the most from your roof.
1. Schedule Regular Inspections
Flat roofs can suffer from issues such as pooling water and debris buildup, and these can go unnoticed without regular checks.
You should ideally aim to inspect your roof at least twice a year, once in the spring and once in autumn. Checking your roof after any storms or extreme weather is also a good idea.
Here’s what to look for:
- Any signs of damage
- Ponding or pooling (where water accumulates and doesn’t drain away for a long time, if at all)
- Cracks in materials
- Blocked drains.
2. Keep the Roof Clean and Clear
If your flat roof is near any trees or there’s overhanging greenery, you’ll need to put in a little extra maintenance work to keep it clean and clear from debris.
You need to clean your roof regularly to stop leaves, twigs, moss and dirt from building up. This is important, as this kind of debris can trap moisture, encourage algae growth and clog drains.
When you’re cleaning, just make sure not to use harsh tools that might damage the membrane. Better still, call in a professional to do it for you.
3. Ensure Proper Drainage
Flat roofs need a slight pitch or drainage system to direct water away from the surface. This makes it doubly important that gutters and downspouts are kept clear of blockages. If they’re clogged, they won’t work properly.
If you notice water pooling in the same area after every rainfall, it could be a sign that the drainage needs professional attention.
4. Repair Minor Damage Promptly
Small cracks, splits or blisters in the roofing material may not seem like serious problems, but they can quickly worsen if left untreated.
If you notice any damage, it’s best to have them repaired as soon as possible. Temporary DIY fixes might help short-term, but you need to bring in professional Kent roof repair and maintenance experts for a long-term solution.
5. Limit Foot Traffic
Unlike pitched roofs, some flat roofs can act as terraces, roof gardens or even service areas. But the roof should only be walked on if the structure has the proper reinforcement, and it has been designed for this purpose.
Regular foot traffic on a standard flat roof (one not designed to be walked on) can weaken the surface, especially during wet or icy conditions. So try to limit access to your roof and use protective walk pads if regular maintenance is needed. Always wear soft-soled shoes and avoid dragging equipment across the surface.
6. Watch for Internal Warning Signs
Sometimes roof problems show up inside the property, before they’re actually visible on the roof itself.
Look out for water stains on ceilings, peeling paint or mould growth – all of these could indicate a leak from the flat roof. If caught early, these signs can help you pinpoint the problem before major structural damage occurs.
7. Apply a Roof Coating
A protective roof coating can help to add an extra layer of waterproofing and UV resistance to your flat roof. These coatings help extend the life of the existing membrane and can improve energy efficiency by reflecting sunlight. It’s recommended to use a professional for this, to ensure proper coverage and application.
