A season by season roof maintenance guide for homeowners
Most roof problems start small and stay hidden until a ceiling stain or a slipped tile forces the issue. Here is what you can reasonably check yourself through the year, and what genuinely needs a roofer with a ladder or a tower.

What you can actually check from the ground
You do not need to get on a roof to spot the early signs of trouble. Walk round the outside of the house on a dry day and look at the roofline against the sky. Tiles or slates that look out of line, gaps where one is missing, or a dip in the ridge line are all things you can pick out with the naked eye or a pair of binoculars.
Check the gutters while you are down there too, especially after a windy night. Debris hanging over the edge, greenery growing out of the joints, or dark drip marks on the brickwork below a gutter run all point to something worth looking at properly. In Leamington Spa and Warwick, where a lot of housing stock has original clay guttering or older cast iron, these joints are often the first thing to move as the property settles.
Inside the house, a torch and ten minutes in the loft tells you more than most people expect. Look for daylight coming through anywhere it shouldn't, damp patches on the felt or timbers, and any sagging in the roofing felt between the rafters. None of this requires going near the roof itself, just a bit of time and a decent torch.
What needs someone with proper access
Anything that involves actually getting onto the roof slope is not a DIY job, and we'd say that regardless of who's asking. Ladders on soft ground, wet tiles, and a roof pitch you don't normally stand on are a bad combination, and it only takes one slip to turn a small repair into a serious injury.
A roofer with proper access equipment can check things you simply cannot see from the ground: the condition of the mortar bedding on ridge tiles, cracked or delaminating slates that look fine from a distance, flashing around chimneys and roof lights that has come away slightly, and the state of any valleys where water concentrates. These are the areas where small faults turn into leaks fastest.
If you're in Rugby or Kenilworth and haven't had the roof looked at from above in a few years, it's worth booking an inspection even if nothing looks obviously wrong. Catching a lifted ridge tile or a hairline crack in a valley before winter is far less disruptive than dealing with a leak once the weather turns.
Moss, algae and why it matters more than it looks
Moss on a roof is often dismissed as cosmetic, but it does more damage than people think. It holds moisture against the tile or slate surface for long periods, which speeds up frost damage in winter and can encourage the edges of concrete tiles to break down over time. It also builds up in valleys and behind chimneys, where it can dam water and push it under the tiles rather than off them.
North-facing roofs and those shaded by trees are the worst affected, and we see a lot of this on the older tree-lined streets around Warwick and Kenilworth. If moss is building up thickly, particularly in valleys or along the eaves, it's worth having it cleared rather than left to spread.
Moss removal from a roof surface needs care. Scraping too hard can damage the surface of the tile itself, and pressure washing at the wrong angle can force water up under the laps. It is one of those jobs that looks simple but is easy to do badly, so it's worth having it done properly rather than tackled with a stiff broom on a Saturday afternoon.
Ventilation is the maintenance job nobody thinks about
A well maintained roof needs air moving through the loft space, not just sound tiles and clear gutters. Without adequate ventilation, moisture from the house rises into the loft and condenses on the underside of the roof timbers and felt, which over years leads to rot, mould, and a musty smell that never quite goes away.
Signs of poor ventilation include black mould spots on the roof timbers, damp insulation, or condensation on the underside of the felt when you check the loft in cold weather. This is separate from a leak, though it's often mistaken for one, and it tends to get worse if a loft has been insulated more heavily without anyone checking the airflow at the eaves.
Improving ventilation is usually a case of clearing blocked eaves vents, adding tile vents where needed, or making sure existing vents haven't been covered over by loft insulation pushed too far towards the edges. It's a straightforward fix once identified, but it does need someone who knows what they're looking at in the loft, not just a glance with a torch.
Gutters, fascias and the parts that take the most punishment
Guttering does a thankless job and gets the least attention until it fails. A gutter that's sagging, pulling away from the fascia, or overflowing in heavy rain is not just an inconvenience, it's sending water straight down the wall of the house, which over time damages pointing, render and even the foundations in bad cases.
Fascias and soffits sit right behind the guttering and take a lot of the weather that the roof edge sheds. Timber fascias in particular can rot quietly for years, especially where a gutter has been overflowing onto them without anyone noticing. Once the timber softens, the guttering brackets have nothing solid to fix into, and that's when a small maintenance job turns into a bigger one.
Clearing gutters twice a year, once after the worst of autumn leaf fall and again in spring, is one of the cheapest and most effective things a homeowner can do. It costs little in time and prevents a lot of the water damage we get called out for in Solihull and Coventry each winter.
Getting ready for autumn and winter
Autumn is the sensible time to get any roof issues sorted before the weather makes access harder and repairs more urgent. Falling leaves clog gutters fast, and the first proper frost of the year will find any weakness in mortar joints or flashing that's been quietly failing over summer.
Winter brings its own specific risks. Wind can lift tiles that were only just holding on, heavy rain finds its way through gaps that were dry all summer, and snow sitting on a roof adds weight that a well maintained roof handles fine but a neglected one might not. Ice can also force its way into small cracks in mortar or lead flashing and widen them considerably as it expands.
If you're planning any roof work for the year, autumn is generally the better window than the depths of winter, both for weather conditions and for getting booked in before everyone else has the same idea when the cold snap hits.
The short version
- Check the roofline, gutters and loft from the ground and inside the house regularly rather than waiting for a leak.
- Leave anything on the roof slope itself, including flashing and ridge checks, to someone with proper access equipment.
- Moss holds moisture against tiles and speeds up frost damage, so clear it before it spreads across valleys and eaves.
- Poor loft ventilation causes condensation damage that looks like a leak but has a different cause and fix.
- Clear gutters at least twice a year to protect fascias, brickwork and the roof edge itself.
- Autumn is the best time to get repairs done before winter weather makes access harder and problems more urgent.
