Top 7 Causes Of A Leaking Roof In Kitchener


There are few things more worrisome than a leaking roof. Kitchener homeowners know intuitively that unchecked leaks lead to water damage, which can cost an arm and a leg to fix. It’s better to spend the necessary money to resolve leaks than deal their aftermath.

But how do roofing leaks occur in the first place? And is it possible to prevent them before they develop?

Following are the seven most common problems that can cause a leaking roof in Kitchener. If you know what to look for, you’ll be able to take preventative measures. Or better yet, schedule a professional roofing inspection and rely on a seasoned roofer to make any necessary repairs.

#1 – Dilapidated Flashing

The thin pieces of metal found around the perimeter of your chimney and along the various joints of your roof are known as flashing. Its purpose is to divert water away from these areas, preventing moisture penetration.

It’s a form of weatherproofing.

Flashing isn’t impervious to age or harm. Over time, it can develop cracks or detach from the roofing’s surface, both of which will compromise its seal and allow water to seep inward.

#2 – Aging Shingles

While some types of shingles are more durable than others, all are susceptible to damage. And the older they get, the more susceptible they become. Even if they don’t chip, crack, break, or fall off, they can erode to the point that they’re unable to effectively keep out moisture.

This predicament can set the stage for a leaking roof. Kitchener attics exposed to persistent moisture can eventually host mold and mildew, allow heat loss, and become the point of origin for structural damage. If you suspect this is a problem, it’s a good idea to schedule an attic assessment.

#3 – Missing Shingles

The shingles are the first line of defense against the elements. If any are missing, they should be replaced immediately. Otherwise, rain and other moisture are likely to penetrate your roofing.

#4 – Accumulated Debris

Leaves, branches, and twigs can trap water on a roof rather than allowing it to run off. This trapped water can sometimes find its way into the space between shingles and the underlayment.

Don’t allow debris to accumulate on your roofing. If you notice leaves and other material starting to collect, clean them off.

#5 – Clogged Gutters

Your gutters are there to funnel water away from your roof to the ground. But they won’t be able to do their job if they become blocked. Everything from leaves and twigs to shingle grit and mud can cause an obstruction.

Water that remains in the gutters can eventually damage your roof and cause leaks.

#6 – Improperly Sealed Valleys

Poorly sealed valleys can also cause a leaking roof. Kitchener homes often look gorgeous from the curb, but conceal serious water damage stemming from rainwater getting past seals where two areas of roofing meet.

Ideally, these valleys would be perfectly sealed so that rainwater is able to run off. But cracks in the seals can allow penetration.

#7 – Poorly Installed Skylight

Skylights are problematic because they’re often installed poorly. Sometimes, the measurements taken by the contractors are imprecise, which causes an imperfect fit. The imperfect fit compromises the seal around its frame, which allows water to seep through.

In addition, the rubber around the glass portion of the skylight can deteriorate with age. This too will undermine the seal, resulting in a leaking roof. In Kitchener, skylights are relatively common. If you have one, have an experienced, licensed, and insured roofing contractor evaluate its condition.
