The effects that snow and ice are having on your roof

It is every homeowners dream (especially here in the UK) to wake up to a fresh sheet of crisp snow, but instead we are usually greeted with a fresh sheet of frost, ice or rain. It is also every homeowner’s dream that his or her families are home in such weather. Are you winter ready? Whilst a lot of people rush to the Internet for winter tips, only a handful of them remember to guard their homes against impending ice and snow and anything the British weather wants to throw at us. Your roof goes through a lot and the ice and snow can be very detrimental if it is not removed for a long time.


Stress on the roof

Ice build-up on your roof could cause you the worst nightmare when it caves in because of the accumulated weight over time. When the temperatures hit below freezing point, rainwater flows to the lowest point of your roof and condenses to form large ice blocks. As the size of the ice blocks increase so does the weight, resulting in stress on the roof, leading to leaks and cave-ins.


The freeze/thaw cycles

Nothing’s more potentially dangerous than water creeping in the tiniest spaces of your roof during winter. Water tends to freeze and expand the cracks. When there’s little heat (just enough to melt the ice), the expanded space accommodates more water that then freezes again and expands the cracks wider. Subsequent freeze and thaw cycles continue posing more leaking and cave-in risks for your roof.


Reduced roof lifespan

As snow and ice continue to accumulate on the roof top, the reinforcements weaken and cracks expand further. Sooner than later, your roof will be a ticking bomb; a strong wind could actually blow it away. If there your rooftop has visible cracks and serious leaks, its replacement time is due.

Having a proper roof maintenance plan is the ultimate solution to saving your roof from the unanticipated troubles. When purchasing roofing materials, consider those with tough substrates. Asphalt shingle roofs have weak reinforcement; hence they’re susceptible to being bent by the weight of the ice. Find a roof maintenance expert and task him/her to remove any accumulation of snowfall deeper than 5 inches.
