If there’s one thing Leeds does spectacularly well, it’s September rain. That early-autumn switch (think cooler nights, surprise showers and the odd “where did that come from?” downpour) can expose every weakness in a roof.
Here’s a step-by-step checklist to get your home rain-ready before the rain rolls in over the Aire.
1. Walk the perimeter and look up (no ladders needed)
Start simple. Do a slow lap of the house after a dry spell, then again after a shower. Bring binoculars if you’ve got them.
What to look for:
- Slipped, cracked or missing tiles/slates (common after summer heat expansion)
- Dips along the ridge line or valleys (where two roof slopes meet)
- Lead flashing around chimneys and dormers that looks lifted, split or stained
- Moss mats or plants in gutters (tell-tale of trapped moisture)
Pay extra attention to north-facing slopes, which stay damp longer and grow moss faster.
2. Clear gutters and downpipes
Gutters are the first line of defence in a Leeds downpour. If they’re full of last year’s leaves or summer moss, water will back up under tiles and over brickwork.
Do this now:
- Scoop out debris, then flush with a garden hose until water runs freely
- Check joints for drips and replace perished rubber seals
- Make sure downpipes discharge into working drains or gullies (no pooling by the foundations)
- Install simple leaf guards if you’re under mature trees
- Consider a professional gutter clean
Blocked gutters plus a September cloudburst is how you get damp patches, flaking paint and green streaks down the render.
3. Check valleys, verges and flashings
Valleys carry huge volumes of water in a storm. Flashings keep water out where the roof meets chimneys, walls or skylights. Harsh winter weather followed by summer expansion and September rain can nudge these just enough to leak.
Spot the red flags:
- Staining or verdigris (a bright bluish-green patina on copper or brass) trails on lead
- Cracked mortar on ridge/hip tiles
- Daylight visible around a chimney breast in the loft
If you’ve got an older stack (we see plenty of these around Burley and Hyde Park), ask a pro to assess pointing and flaunching. A modest repair now beats a soaked bedroom ceiling later.
4. Sweep off moss (the gentle way)
Moss acts like a sponge, holding water against tiles and creeping under laps. That’s a problem when the rain sets in.
Best practice:
- Avoid pressure washing (it strips surface protection and can force water where it shouldn’t go)
- Opt for careful manual removal and, if appropriate, a professional biocide treatment suitable for your tile type
- Keep the focus on drainage paths, like eaves, valleys, and behind chimneys
Homes near Woodhouse Ridge or the Meanwood Valley Trail tend to be moss-prone thanks to shade and moisture.
5. Flat roof owners: look for blisters, splits and ponding
From dormers in Beeston to kitchen extensions in Seacroft, flat roofs are everywhere in Leeds. And autumn rain exposes weaknesses fast.
Your September checks:
- Gently press any blisters. If water seeps, it needs attention
- After rain, note any standing water that remains 48 hours later (bad falls or blocked outlets)
- Inspect edge trims and upstands where water can creep in
Modern GRP fibreglass and quality membranes cope brilliantly if installed well, but even good systems need clear outlets to avoid ponding.
6. Go into the loft after a shower
The easiest way to find leaks? Look from the inside, right after rain.
Bring a torch and check for:
- Dark, damp patches on felt, rafters, or insulation
- Drips around nails (sometimes called “nail rot” in cold snaps)
- Musty odours (early mould thrives in warm-wet September lofts)
While you’re there, make sure insulation isn’t blocking eaves ventilation. Good airflow stops condensation when nights turn cooler.
7. Trim back branches and tidy the roofline
Overhanging sycamore giving you shade in summer? Lovely. Dropping twigs and clogging gutters in autumn? Less lovely.
Before the heavy rain:
- Cut back branches that touch or overhang the roof
- Inspect fascia/soffit boards for rot or gaps (birds and squirrels adore them)
- Re-secure any rattly sections (strong equinox winds in September can rip them free)
8. Test your drainage at ground level
When the heavens open, all that water has to go somewhere. If gullies and drains are silted up, it can end up against your walls or, worse, under the floor.
Two-minute test:
Pour a bucket of water into each gully. It should disappear quickly without bubbling back. Lift simple grates and remove silt. If you’re near the River Aire or the canal, keeping surface water moving away from the building is extra important in sustained rain.
9. Tidy the “little” weaknesses now
Autumn is ruthless on roofs and finds every small flaw.
Worth a once-over:
- Cracked or missing mortar on ridge/hip tiles
- Loose verge caps on modern interlocking tiles
- Perished sealant around rooflights
- Satellite dish fixings (a favourite leak source on terraces around Holbeck and Hunslet)
A minor half-day repair now is cheaper than internal replastering later.
10. Photograph your roof for peace of mind (and paperwork)
A quick set of phone photos (include roof slopes, gutters, chimneys and the loft) is handy for tracking changes and invaluable if you ever need to speak to insurers after a storm.
If you can’t safely see what you need from ground level, a professional roof survey with close-up images is a neat way to document condition before the wet season bites.
11. Know when to call in a professional
Some jobs are straightforward DIY. Others are best left to roofers with the right kit (and insurance). That includes:
- Re-bedding or re-pointing ridge tiles
- Leadwork at chimneys or abutments
- Repairing valleys and replacing cracked slates at height
- High-level access on townhouses or steep pitches
