Whether it’s a big or small roof, over the course of time, roof leaking is probably the most common roof problem that you face at your residential or commercial place.
So, what causes your roof to leak in the first place? In this article, we at Kimball roofing has curated the top common causes of roof leaks and how to possibly fix them.
Top 10 common causes of roof leaks:
1. Damaged Flashing
Roof flashing is a galvanized steel use to divert water away from the critical area on the roof. Flashing is always installed in valleys where two roof slopes meet, and therefore, is susceptible to getting cracked.
Generally, roofers would use material like tar to seal the flashing together and over time, this can get corroded by the wind, air, moisture, etc. and therefore, damage the flashing.
2. Broken Shingles
Roof shingles are roof covering consist of individual overlapping elements used to protect your inner roof. Shingles can easily be damaged by strong wind and harsh weather, and therefore, broken shingles is one of the most common causes of roof leaks.

3. Skylights Problems
Improper fixture of skylights can definitely lead to a roof leak. As you know, skylights act as a direct barrier between the outside and your house and therefore, any problem occurring on your skylights has a direct impact on your living.
The 2 most common cause for skylights leakage is either they were improperly installed (not properly measured) or the decayed insulation along the skylights edges.
4. Clogged Gutter
A gutter is probably the place where it gets corroded the most. As you know, it is the main component of the water discharge system of the roof. Any clogging in the gutter passage can make the water gets accumulated in one area and hence, the water will have more of an opportunity to seep through cracks.
How To Fix This?
It’s fairly simple and straightforward. To fix clogged gutter, all you have to do is climb up the ladder and investigate what’s blocking the gutter passage.
Leaves are often the main culprit behind this problem. Then you can either clean off the blockage by yourself or hire a roof cleaning company in Portland to get the job done for you. A gutter and roof inspection can help prevent this.
5. Cracked Chimney
Cracked chimney is a sure fire way for water to get leaked into your house from the roof. Since the chimney is directly connected with the roof, any crack around the area of connection can easily make the water seep through.
Since the area around where the chimney is connected with the roof is being sealed with mortar, tar and sand, this can easily get eroded over time.
6. Vent Booting Is Cracked
Roof vents are used for a ventilation process in your house, mostly in the steep-slope roof. The main goal is to expel any extra moisture in the house and to provide a means of allowing outside air to enter and exit attics and ventilation spaces.
One of the main reasons why vent cracks is due to an improper use of nail for flashing of the vent on the roof, which over time, can make the flashing breaks and cracks
7. Ice Dam Buildup
According to the definition here, An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation and other areas.
A non-uniform distribution of temperature from outside and inside the house leads to formation of ice dams.
8. Condensation In The Attic
Attic condensation generally happens during winter & spring months when warm, moist air from the main living area rises into the attic space. When that warm, moist air meets the chilly underside of your roof’s deck, condensation occurs.
In winter, the condensation turns into frost, which doesn’t posses any harm, but then when the frost melts, this turns back into condensation again, which makes the insulation and wood wet. Now, your attic is vulnerable to mold and rot, which can ultimately makes the roof leak.
This is a very obvious roof leak cause and holes form directly on your roof and surrounding materials have the largest impact on your house. This is often cause by animals or heavy storms and hails, which makes it fairly difficult to prevent.
Roof holes can also be more sneaky, living for years until an inspection uncovers them.
10. Age Of Your Roof
Just like anything out there, roofs also have their own lifetime. If after going through the above 9 causes of roof leaks, you still couldn’t figure out the reasons, it could be simply because your roofs have reached it’s time limit.
