As the colder months approach, commercial and industrial buildings across the UK face a familiar challenge: protecting their roofs from the harsh realities of winter. From freezing rain and snow to high winds and temperature fluctuations, winter weather can accelerate wear and tear, especially on older or poorly maintained roofing systems.
At NSS, we’re nationwide specialists in maintenance, cleaning, hire and testing services. Established in 2005, we bring unparalleled expertise to commercial property maintenance, working with businesses across multiple industries from major airports to leading retailers. As part of Premier Technical Services Group Ltd (PTSG) and their Building Access Specialist Division, we combine extensive industry experience with advanced plant and access technology. Our in-house team works around the clock across the country, setting new standards for safety, speed, and transparency.
We believe that proactive roof maintenance is the key to avoiding costly repairs and operational disruption. Whether you manage a warehouse, retail unit, school, or manufacturing facility, now is the time to act.
1. Book a Professional Roof Inspection Before the Weather Turns
The first step in any winter roof maintenance plan is a thorough roof inspection. While some issues may be visible from ground level, many vulnerabilities go unnoticed until they cause serious problems. A professional survey can identify:
- Cracked or damaged roof tiles and slates
- Blocked gutters and downpipes
- Compromised flashing and lead work
- Failing sealants around rooflights, joints, and fixings
- Ponding water or poor drainage
- Algae and moss growth
At NSS, our experienced technicians use our fleet of access solutions including truck-mounted platforms, scaffolding, and drone surveys to provide comprehensive roof assessments. Our detailed photographic reports include clear recommendations, giving you a roadmap for maintaining your roof’s integrity throughout winter.
2. Clear Gutters and Downpipes to Prevent Water Damage
Autumn leaves, moss, and debris can quickly clog drainage systems, especially on large commercial buildings. When gutters and downpipes are blocked, water backs up and pools on the roof. In freezing conditions, this water can turn to ice, adding weight and increasing the risk of cracking, leaks, and structural stress.
The statistics are striking:
- 70% of commercial roof leaks are caused by blocked or poorly maintained gutters. Blocked gutters lead to water pooling and penetrating roof membranes, causing damage to internal structures.
- Water ingress is one of the top three causes of commercial property insurance claims in the UK. Regular gutter maintenance is a key preventative measure flagged by insurers to reduce claim risk.
- Unmaintained gutter systems can lead to repairs costing 5-10x more than scheduled cleaning. Reactive fixes due to water ingress, damaged fascias, or internal ceiling collapse can far exceed the annual cost of a PPM contract.
- 1 in 3 commercial properties in the UK experience preventable drainage-related roof damage annually. A proactive gutter cleaning regime drastically reduces unplanned downtime and operational disruption.
- Standing water from blocked gutters can add up to 20% extra weight load to the roof structure, especially on flat and industrial roofs, leading to long-term structural stress or collapse risk.
- Legionella and pest infestations often begin in stagnant water found in neglected roof drainage systems.Proper drainage is not just structural – it’s a hygiene and health compliance issue.
- Businesses with active roof and gutter PPM see up to 50% fewer emergency call-outs annually. Planned maintenance extends asset life and reduces reactive costs significantly.
Regular cleaning and maintenance of drainage systems is essential. Our roof maintenance teams ensure that water flows freely away from your building, reducing the risk of winter-related damage and keeping your roof in optimal condition.
3. Repair Minor Damage Before It Becomes Major
Small issues like cracked tiles, loose fixings, or deteriorating sealants may seem insignificant. But in winter, every flaw is magnified. Wind-driven rain can penetrate gaps, frost can widen cracks, and snow can conceal problems until it’s too late.
NSS offers fast, effective repair solutions for slate and tile roofs, roof light replacement, and preventative maintenance. These services are designed to minimise disruption to your operations while restoring full protection to your roof.
4. Consider Energy Efficiency and Building Performance
Winter-proofing isn’t just about protection, it’s also about performance. A well-maintained roof helps regulate internal temperatures, reduces heating costs, and improves comfort for building occupants. Fixing leaks, gaps, and damaged rooflights reduces heat loss, contributing to energy efficiency and sustainability.
Higher utility costs can often signal underlying roof damage affecting insulation. Addressing these issues before winter can lead to significant cost savings throughout the season.
