5 Things to Watch Out for This Winter if You Have a Flat Roof

Flat roofs are a fantastic option for homes and extensions—they’re sleek, space-efficient, and perfect for adding things like solar panels. But, like anything, they come with their quirks, especially in winter. Here are five things to keep an eye on to keep your flat roof in great shape as the colder months roll in.

1. Keep an Eye on Pooling Water

Flat roofs don’t have the luxury of a slope to help water run off, so pooling water can be an issue—especially after heavy rain or melting frost. It’s not just a weather problem; long-term puddles can speed up wear and tear on your roof.

• What to look for: Puddles that stick around longer than a couple of days.
• ‍What to do: Make sure your roof’s drains and gutters are clear and functioning. A quick check every now and then can work wonders.

2. Clear Those Gutters and Drains

This one’s not about weather—it’s about leaves. Autumn might be over, but those soggy leaves sitting in your gutters are still causing problems. Blocked gutters mean water can back up onto your roof, potentially leading to leaks.

• What to look for: Overflowing gutters or water creeping onto your roof edges.‍
• What to do: Clear out gutters regularly during the season. A little effort now saves a big headache later!

3. Flat Roofs Are Strong, But... Watch the Weight

Your flat roof is tough, but it wasn’t designed to hold loads of extra weight for long periods. It’s not just about snow (although wet snow can get surprisingly heavy). Things like debris, outdoor furniture, or even a forgotten ladder can add unnecessary strain.

• What to look for: A build-up of heavy items, whether it’s natural (like snow) or something you left up there.‍
• What to do: After a storm or garden DIY session, give your roof a once-over to make sure it’s clear of clutter.

4. Check for Small Cracks or Lifting Edges

Winter isn’t just hard on your roof because of the cold—it’s a time when any small issues can quickly get worse. Little cracks or lifted edges might not seem like a big deal now, but when water freezes, it expands and can make the damage worse.

• What to look for: Tiny cracks, bubbling materials, or any signs of wear and tear.‍
• What to do: Seal small cracks before they grow. You can use a flat roof repair kit for DIY jobs or call in a professional for anything more significant.

5. Consider How You’re Using Your Flat Roof

Got a flat roof terrace or balcony? Winter can take its toll on those spaces, too. Furniture, planters, or even your rooftop lights can trap moisture or create pressure points if left unchecked.

• What to look for: Furniture that’s soaking wet or areas where water gets trapped.‍
• What to do: Store your outdoor furniture indoors if possible, or make sure it’s raised off the roof surface to allow proper drainage.

Bonus Tip: Winter and Solar Go Hand-in-Hand
