The Impact of Climate Change on Roofing Materials — Future-Proof Your Home

Homeowners in Somerset are seeing more extreme weather. That matters to your roof. Changes in rainfall, stronger storms and hotter summers all affect roofing materials. This guide explains risks and gives clear steps to future‑proof your home.

Why climate change matters for roofs

Roofs form the first line of defence against the weather. When the weather changes, roofs face new stresses. Heavy downpours drive more water through drains and gutters. Stronger winds can lift tiles and ridge coverings. Warmer temperatures and stronger sunlight speed up material wear. Small faults become big problems faster.

Common risks to roofing materials

More intense rainfall

Heavier rain increases the load on guttering and rainwater systems. Pooled water on flat roofs becomes more likely. Worse drainage raises the risk of leaks and damp. Gutters and outlets need to cope with higher flows.

Stronger winds and storms

High winds can displace ridge tiles, slates and fixings. Loose mortar and degraded battens make uplift more likely. After a storm, missing or slipped coverings are a common cause of leaks.

Heat and UV exposure

Higher temperatures and stronger UV light speed up ageing in some membranes and sealants. Thermal movement causes fixings and joints to loosen over time. On flat roofs, older felt systems can become brittle.

More biological growth

Milder, wetter winters can increase moss and lichen on pitched roofs. Moss holds moisture next to tiles and slates. That accelerates wear and can lead to blocked gutters and drips.

Materials and systems that cope better

Choice of material matters. No roof is immune, but some materials and systems give longer service with less maintenance.

• Natural slate and high‑quality tile systems. They resist wind and heavy rain when fitted and fixed correctly.
• Modern flat‑roof membranes such as fibreglass (GRP) or EPDM rubber. These give long‑lasting waterproofing when detailed properly.
• Durable lead flashings and properly formed flashings around chimneys and valleys. Lead remains a standard solution where shaped flashing is needed.
• Secure mechanical fixings and modern ridge systems to reduce wind uplift risk.

Maintenance and inspection to reduce risk

Regular checks catch problems early. Small defects grow fast after extreme weather. A planned inspection looks for slipped tiles, degraded flashings and blocked gutters. Clean, repair and replace as needed.

• Keep gutters clear. Blocked gutters cause overflow and damp.
• Remove moss and vegetation from pitched roofs carefully.
• Check leadwork and flashings after storms.
• Inspect flat roofs for ponding and splits in membranes.

For repairs after damage, see our Roof repairs page.

Upgrades to future‑proof your roof

Improve ventilation and insulation

Good ventilation prevents condensation and helps roof timbers to stay dry. It also reduces thermal stress. If you are upgrading insulation, follow current guidance. For ventilation options, see Improve roof ventilation.

Replace old materials with resilient systems

Older felt roofs or brittle membranes are more likely to fail under changing weather. Consider modern fibreglass or EPDM systems for flat roofs. For pitched roofs, check that battens, fixings and underlay meet modern standards before refelting or retiling.

Water management and drainage

Increase gutter capacity and check downpipes. Fit leaf guards where trees increase debris. On low‑pitch areas, improve falls and drainage outlets to avoid ponding.

Practical checklist to future‑proof your roof

• Book a roof inspection after every major storm.
• Keep gutters and outlets clear and well‑fixed.
• Remove moss and vegetation promptly.
• Check flashings and ridge work for cracks or loose mortar.
• Consider upgrading flat roofs to GRP or EPDM membranes.
• Improve loft insulation and ventilation where possible.
• Use mechanical fixings on exposed tile or slate roofs.
