RAINWATER MANAGEMENT
GUTTER INSTALLERS KEY TO UK STORM WEATHERING
A new survey from Wavin Osma reveals extreme seasonal weather is driving an increase in guttering work.
E
xtreme weather and changing climate patterns are contributing to a growing volume of guttering work across the UK, according to new research from plumbing and drainage manufacturer Wavin. The nationwide survey of building professionals highlights the increasing pressure on rainwater systems, with more than a third (36%) of respondents attributing a rise in guttering jobs to heavier rainfall. Reflecting this trend, almost all professionals report that heavy rainfall has affected the gutters they have been called out to repair, underlining the scale of the issue facing installers and merchants alike.
The findings also point to a shift in how tradespeople are advising customers. Nearly a third (32%) now recommend post-storm inspections as standard practice, helping homeowners identify issues early and avoid more costly repairs further down the line. In addition, more than a third (38%) are encouraging the specification of higher quality, more durable systems to reduce the risk of blockages and failures — particularly as storms and impact damage continue to account for a significant proportion of gutter- related problems.
Steve Skeldon, above ground product manager at Wavin, says: “The role of professionals has never been more important in helping homeowners understand the impact of Britain’s increasingly extreme weather on their guttering systems. By clearly explaining how issues like blockages, leaks or misaligned gutters can lead to damp, structural damage or costly repairs, tradespeople play a key role in raising awareness.
“They can also guide homeowners towards practical, preventative measures — from routine inspections and timely maintenance to recommending system upgrades where appropriate. Enhancements such as higher- capacity profiles, better suited to a property’s roof size, shape or location, can make a significant difference in preventing damage.” With storms and high winds placing additional strain on buildings, guttering systems are often the first line of defence. Dislodged components, debris and more intense rainfall are increasing the likelihood of system failure, particularly where products are underspecified or poorly maintained — presenting both a challenge and an opportunity for merchants to support their trade customers.
Skeldon says that Wavin Osma’s guttering range is designed to meet these demands, offering six profiles supported by a hydrodynamic outlet capable of handling up to 30% more water than comparable systems.
“Options including RoundLine, SquareLine, DeepLine and StormLine are engineered for secure installation, thermal movement and leak prevention, helping installers deliver reliable performance in more challenging conditions,” he says, adding: “StormLine, a high-capacity domestic system, is specifically developed for heavy rainfall, featuring a raised front edge to control rainwater overshoot during intense downpours — providing added reassurance for both installers and homeowners.” BMJ
WHEN DRAINAGE NEEDS TO DISAPPEAR
Slot drainage systems are helping contractors deliver reliable surface water management in modern urban developments.
U 40
rban regeneration projects increasingly require drainage solutions that combine reliable surface water management with a discreet appearance. Slot drainage systems are becoming a preferred choice where architects
and engineers want to minimise the visual impact of drainage without compromising performance.
ULMA’s slot grating system has been developed to integrate seamlessly within paved surfaces while delivering the hydraulic
capacity required in busy pedestrian areas and public spaces. The narrow slot inlet provides efficient water capture while maintaining a clean and unobtrusive finish. The system was recently installed at the
