Autumn is the most important season for Warwickshire roof maintenance. Before winter, clear gutters and valleys of leaf fall, check ridge and flashing condition, and remove moss on north-facing slopes. Riverside Stratford and Forest of Arden properties need this most, as heavy tree cover blocks drainage every October.
September and October are the most important months in the roof maintenance calendar for Warwickshire homeowners. The combination of the summer drying period ending, the first autumn storms arriving, and the leaf fall season loading gutters and valleys simultaneously creates a concentrated window of risk. This guide covers the practical actions that prevent the majority of winter roof emergency calls we receive.
In over 20 years of roofing across Stratford-upon-Avon and Warwickshire, the pattern is consistent. The calls that come in November and December — overflowing gutters, damp patches on bedroom ceilings, wall staining — have their origins in September and October inaction. A blocked valley that fills with wet leaves in October becomes a leak source when the first sustained frost and thaw cycle arrives. An overflowing gutter from November onwards saturates the wall face, which then takes until spring to dry out.
The Avon Valley position creates specific seasonal challenges that inland Midlands towns do not share to the same degree. Riverside properties in Bridgetown, Welford-on-Avon and along the Southern Lane approach deal with willow, poplar and horse chestnut leaf fall that is both earlier and heavier than equivalent properties on higher ground. The autumn gutter clear is not optional for these locations.
NFRC maintenance guidance identifies blocked gutters and valleys as a leading cause of autumn and winter water ingress, making pre-winter clearing the single most valuable maintenance task.

Clear gutters are the single most effective leak prevention measure available to a Warwickshire homeowner. The sequence is straightforward: blocked gutters overflow, water runs down the wall face, the wall absorbs moisture, damp patches appear internally. The repair bill for the internal damp and external repointing vastly exceeds the cost of an annual gutter clear.
Timing: the most effective single clear for most Stratford properties is late October to early November, after the main leaf fall but before the worst winter rainfall. Properties with heavy adjacent tree canopy — particularly Welcombe Road, Henley-in-Arden, Alveston and Welford-on-Avon — benefit from a second clear in late August to remove summer debris before the main leaf fall arrives.
Open valleys — the internal angles where two roof slopes meet — are the highest-volume water drainage point on most pitched roofs. They also collect the most debris. A valley blocked with compacted wet leaves retains moisture against the lead or GRP liner constantly, which accelerates deterioration and creates ice damming in hard frost conditions. In our experience, 30 to 40% of the roof leak calls we receive in winter trace back to a partially or fully blocked valley.
Check from the ground: if the valley is not visible from outside the property, or if you cannot confirm it is clear, arrange a professional inspection. The cost of a valley clear is a fraction of the repair cost once water has penetrated.
If your autumn inspection reveals a potential issue, act before November. Work scheduled in October can typically be completed before the worst winter weather. Leaving a known issue until spring means carrying the risk of water ingress through the entire wet season. We offer free no-obligation surveys for all Stratford and Warwickshire properties — call 01789 509542 and we can typically attend within 24 to 48 hours for a survey.

Riverside properties and those with heavy adjacent tree canopy should consider a second clear in late August. Annual maintenance is the most cost-effective approach.
From ground level, a healthy valley should show a clear gap between the tile courses with no debris accumulation visible. If you can see compacted leaves or debris in the valley angle, it needs clearing. If the valley is not accessible from the ground, a professional inspection is the only safe way to confirm clearance.
No. A ground-level inspection with binoculars is sufficient to check for obviously displaced ridge tiles, visible flashing separation and debris in valleys. Never attempt to access your own roof without professional equipment and training. Free professional inspections are available from us across Stratford-upon-Avon and Warwickshire — call 01789 509542.
The priorities are the same but the materials and approaches differ. Period clay tile and slate properties should have valleys and flashings inspected professionally rather than from the ground, as lead and lime mortar deterioration can be difficult to assess visually. Conservation area properties should not have pressure washing or abrasive cleaning applied to tiles under any circumstances.
