A frequent hotspot for leaks are where the roofline hits a siding wall. No matter how close the gutter is to the wall there is always a gap that water can squeeze into. Over time the water can find weaknesses or small areas to make it through. This can cause leaks and sheeting rot over a lengthy period of time. A kick-out flashing will remedy your leak issue.
Is a kickoff flashing causing your leak?
Remove a couple pieces of siding where the roofline meets the wall. The kickoff flashing will be custom fabricated out of aluminum to match the siding color (or roof color). This will be one continuous piece designed to flow water into the gutter. The flashing will be taped underneath the siding and will be installed under the shingles.
If this spot is above a window, it’s often mistaken as a window leak when really the window leak is a symptom of not having a kickoff flashing in place.
The past year, Central Illinois was filled with some very intense hail storms. Many homeowners that receive insurance money to replace hail damage find themselves asking, “My skylight doesn’t look damaged and isn’t leaking, should I still replace it?”
The answer is always “Yes!”
Here’s why: Your roof is somewhat built to accept and resist impact, your skylight isn’t. More specifically your skylight seals are not. While the seals might not be leaking it doesn’t mean they have not been compromised and might in the near future.
Velux, a leading manufacturer in the window and skylight industry, issued a letter on the topic. This letter can be used to persuade your insurance company to release the funds for replacement skylights after a hailstorm.

Seems funny to apply the word “rogue” to humidity. But during midwest winters it fits. Here’s why:
Every winter is bound to have a couple days to a couple weeks of below zero weather. When temperatures start to rise, homeowners start to notice brown spots on their ceiling that resemble roof leaks. This could be a sign of a roof leak; it could also be a sign that the home’s humidity was too high during the cold temperatures- causing attic condensation to freeze.
Furnace humidifiers are often forgotten to be adjusted during winters and create too much humidity. This moisture freezes when it hits your attic
Many homes have humidifiers on their furnaces. Almost all new homes have this or homes with real wood floors. It’s a great thing to have, but homeowners need to be mindful of appropriate humidity levels. If the humidity is set higher than it should be during negative temperatures, the moisture rises up to the attic and before it can escape, it hits the bottom of the snow covered roof and freezes. Sometimes icicles even form off the nails! Once the weather warms up and one of the first things to thaw is attic condensation. Depending on high the humidity has been set on your house, this can be a decent amount of moisture coming down – thus causing brown spots on ceilings. It looks identical to spots from roof leaks.
Tea staining or brown spots can form on your ceiling as frozen attic condensation melts during winter months.
What is the appropriate level of humidity for your home?
If the outside weather is…
20 to 40 degrees, humidity should be less than 40%
10 to 20 degrees, humidity should be less than 35%
0 to 10 degrees, humidity should be less than 30%
-10 to 0 degrees, humidity should be less than 25%
-20 to -10 degrees, humidity should be less than 20%
below -20 degrees, humidity should be less than 15%
This will prevent attic condensation, mold, or any other issues caused by overly humid and warm air.
What about you?
These guidelines are the optimal levels to make your home comfortable, but what about the people living in it? Dryer air is not always the best for us to live in but there are ways to keep both you happy and your home comfortable. Instead of using whole house humidifiers use individual ones when you are using the room. Use programmable timers to turn on and off humidifiers. Buy indoor humidity sensors – these range from $5-$50. Click here to see the “indoor hygrometers” on Amazon.com
It’s so easy to forget to monitor or change your humidity. Many people don’t even realize this is what’s going on until it’s too late – brown spots appear! If this happens to you, don’t panic but it’s still good practice to have a trusted roofer inspect to confirm no roof leaks.
Uncontrolled water is the biggest threat to homeowners. It’s a slow and silent killer. Here are the most common issues we see on homes.
Lack of Kick-Out Flashings. Even if your gutters are pitched correctly and don’t leak, they may appear to be leaking where the gutter butts up the wall. Or it might look like nothing is wrong at all. Overtime, water constantly slipping between the wall and gutter will find its way behind any house wrap or moisture barrier you have in place. Read more about kick-out flashings
Without a kick-out flashing, water is free to run down your siding and can creep behind your house wrap.
Once you remove the house wrap you can see all the damage that the un-controlled water did behind the house wrap.
No Downspout Extensions. Often times homeowners remove these extensions out of aggravation. These extensions might seem like a trip hazard, a pain to mow around, or get trampled easily. – but don’t get rid of them! Your home and your foundation need these extensions to route water away from you home. You can add hinges to these extensions to eliminate all the hassle they cause.

Inadequate or No House Wrap. Depending on when your home was built and the history of your city’s building codes, your home might not have any house wrap or moisture barrier. For example, the City of Bloomington, IL did not start requiring any form of house wrap until the late 70’s. Practically all houses built before the early 70’s (in Bloomington, IL) are without house wrap. Siding, bricks, shakes or any other exterior cladding are not intended to protect your home from water intrusion. If your home does have house wrap, it might be done incorrectly: applied in small pieces, too many mechanical fasteners, or taped incorrectly. There are alternative moisture barriers to house wrap at similar expenses- Read about EnviroDri.

Bad Pipe Flashings. Pipe flashing have a shorter lifespan than your roof and will need replaced a few times before you need a new roof. It’s a simple fix but if the flashing is cut too large, water will still get in. Watch Nick Coyle replace a pipe flashing.

Spring showers bring leaky gutters- Wait no, that’s not right! We’ve recently had a fair amount of homeowners call because they are tired of leaking gutters. It’s usually the lack of kick out flashing which gives the appearance of a leaky gutter but often has hidden disasters associated with it.
What is a kickout flashing?
A Kick out flashing is a tiny but valuable piece of metal that diverts water into the gutter. It’s installed along the wall that the gutter end terminates into. The image below shows a correct kickoff flashing. It’s important to make sure the kickout overhangs a decent amount into the gutter to ensure no water runs along the side wall behind the gutter endcap.
Proper Kickout Flashing
Why is a kickout flashing necessary?
Kick out flashings are needed to direct water into the gutter- in these specific areas, siding is often times notched to fit around the roof section and has the possibility of letting water slip behind the siding and run down the interior wall. Beyond the obvious trouble of improper water control, if your house doesn’t have any housewrap or housewrap failure, the sheeting underneath will often be moldy or rotting without a proper kickout flashing.
Kickout flashing is too short- Water is still likely to run against wall
The images below are of a home in Bloomington, IL that had a powerful combo of the housewrap installed incorrectly and no kickout flashing. Every place the gutter butted up against a side wall, the OSB underneath was completely rotted- our Carlson Exteriors guy was able to push his hand through the OSB easily.
Have you noticed a wet or tea-stained ceiling? It could be from a bad or old pipe flashings. The usual life span of a pipe flashing is 10-15 years but depends on your region’s weather conditions. If you keep an eye on all of your pipe flashings it could save you hundreds of dollars repairing any interior damage that can occur from a leak. Look for any signs of extreme age, deterioration, or cracking. Watch the video to see how easy it is to replace your own pipe flashing!
