Roof Checks After Winter Weather
A guide for North West Homeowners
Winter weather in the North West of England often brings heavy rainfall, strong winds, and fluctuating temperatures. Over time, these conditions can place added stress on roofs and chimneys — particularly where small issues already exist.
This guide outlines common things homeowners across Greater Manchester, Lancashire, Merseyside, Cheshire, and surrounding areas may want to be aware of during or after periods of severe or changing weather.
1. Persistent Rainfall & Water Ingress
The North West experiences higher-than-average rainfall compared to many parts of the UK, which can expose roofing weaknesses over time.
Things to be aware of include:
-
Hairline cracks in tiles or slates
-
Worn or displaced flashing around chimneys and roof joints
-
Blocked or damaged gutters causing water to back up
Water may not enter living spaces immediately and can travel through roof layers before becoming visible indoors.
2. Freeze–Thaw Cycles in Winter
During winter months, temperatures in the North West often fluctuate around freezing.
This can affect roofs because:
-
Water enters small gaps during milder periods
-
Freezing causes that water to expand
-
Repeated cycles may gradually worsen existing cracks
These changes often happen slowly and are easy to miss without closer inspection.
3. Strong Winds & Exposed Roof Areas
Storms and high winds can place additional strain on roof components, particularly on exposed or elevated properties.
Areas that may be affected include:
-
Ridge tiles and verge tiles
-
Flashing around chimneys, dormers, and roof joins
-
Older repairs or weathered materials
Wind-related issues don’t always result in missing tiles — materials can become loosened and remain vulnerable during future storms.
4. Chimneys & Roof Penetrations
Chimneys and roof penetrations are common points of weather exposure, especially on older properties commonly found across the North West.
Potential concerns include:
-
Deteriorating mortar joints
-
Cracked chimney pots or caps
-
Aging seals around vents or skylights
Because these areas are difficult to access safely, issues may go unnoticed from ground level.
5. Signs to Look for Inside the Home
Some roof issues only become apparent indoors, particularly after periods of prolonged bad weather.
Things homeowners may notice include:
-
Damp patches on ceilings or upper walls
-
Peeling paint or wallpaper
-
Musty smells in loft spaces
If these appear following storms or heavy rain, they may indicate an external issue worth investigating
6. Why Roof Issues Are Often Missed
Roofs are among the least frequently checked parts of a property, often because:
-
Access can be difficult or unsafe
-
Many issues aren’t visible from ground level
-
Damage can develop gradually rather than suddenly
Periodic visual checks can help homeowners stay informed about their property’s condition.
Safety Considerations
Climbing ladders or accessing roofs during winter or stormy conditions can be hazardous and should not be attempted. Any inspection approach should prioritise safety, avoid unnecessary risk and use a professional where possible.
