August is the quiet before the storm — literally. The weather is broadly settled, days are long, and access to roofs, gutters and external walls is straightforward. By the time the first autumn gales arrive, minor issues that could have been sorted in an hour become emergency callouts, insurance claims, and interior damage. This guide sets out the practical jobs worth tackling now to get your property through the wettest part of the year in good order.
Roof Covering and Ridge Lines
A visual check of the roof covering from ground level — or better, with binoculars — will reveal most obvious problems. Look for slipped, cracked or missing tiles and slates, and pay particular attention to ridge and hip lines where mortar bedding cracks and dislodges over time. On flat roofs, look for ponding, blistering or splits in the membrane. Anything that looks out of place now is far cheaper to put right in August than in November, when scaffolding goes up in the rain and materials behave less cooperatively.
- ✓Slipped or missing tiles — even a single gap can let in significant water during driven rain.
- ✓Cracked or missing ridge mortar — a common failure point on period properties across Brighton and Hove.
- ✓Damaged or lifting lead flashings at chimneys, abutments and dormers.
- ✓Blistering, splitting or ponding on flat roof membranes.
- ✓Loose or displaced chimney pots and damaged chimney caps.
Gutters and Downpipes
Gutters are the single most neglected component on most domestic roofs. Through autumn they fill with leaves, moss washed down from the tiles, and general debris. By the time winter rain arrives in volume, a gutter that was flowing freely in September is overflowing and running down the external wall, saturating the masonry and tracking into the property. Clearing gutters now — and flushing them through with a hose to confirm the downpipes are running freely — is one of the highest-value maintenance jobs you can do at this time of year.
Overflowing gutters are frequently misdiagnosed as roof leaks. Water running down an external wall saturates the masonry, tracks through the wall cavity, and appears as a damp patch on an internal wall — often some distance from the actual source. If a damp patch appears only during heavy, prolonged rain rather than short showers, the gutters are a prime suspect.
Chimney Stacks
Chimneys are the most exposed part of any roof and the most common source of water ingress on older properties. Open mortar joints, a cracked cap, or failed lead flashings will all let water in — and once the masonry is saturated, frost cycles through the winter accelerate the breakdown rapidly. A stack that needs repointing in August is a straightforward job; the same stack left through a wet winter may need a partial rebuild by spring. If you have not had a chimney looked at in the last few years, late summer is the time to get it surveyed. Our chimney repair service covers repointing, cap replacement, lead flashing renewal and full rebuilds.
Lead Flashings and Valleys
Lead work is at its most vulnerable heading into winter. Thermal movement through the cold months — when lead contracts sharply overnight and expands during sunny mornings — will open up any existing hairline cracks and lift flashings that were already marginal. Check around chimney stacks, at the junctions between roof slopes and walls, and in valleys. If a flashing is lifting at the chase or showing visible cracks, it is far better to re-dress or replace it now than after it has let water into the roof structure.
Loft and Interior Checks
- ✓Check the loft for any existing damp patches or staining on timbers and insulation.
- ✓Look for daylight through the roof — any visible gaps indicate a missing or displaced tile.
- ✓Ensure loft ventilation is unobstructed — blocked vents or insulation pushed tight to the eaves causes condensation, which is often mistaken for a roof leak.
- ✓Check pipework and water tanks in the loft are lagged before the first frost.
- ✓Confirm any loft hatches are properly sealed to prevent warm air escaping and condensation forming.
Why August Is the Right Window
The practical case for getting this work done in late summer is straightforward. Access is easier and safer in dry, settled weather. Mortar, sealants and membranes cure properly in warm conditions — the same materials laid in cold, damp winter weather perform noticeably worse. Leadwork dressed in warm conditions settles into its correct shape before the thermal stress of winter begins. And most importantly, you are fixing problems before the weather that will expose them arrives. A roof that is sound in August is a roof that is far more likely to stay sound through to spring.
If you would like a condition survey of your roof, gutters, flashings or chimney ahead of the winter, we carry out free inspections across Brighton, Hove and the wider Sussex area and provide a clear written report of anything that needs attention — with no obligation to proceed.
