If you’ve had a recent storm blow through…
You may have noticed some missing roof shingles.
Or maybe your roof is missing just one shingle.
And you’re wondering.
“Will my roof leak with one shingle missing?”
Most of the time, when you see a missing shingle, you’re looking at one tab of a 3-tab shingle.
With a strong gust of wind, the shingle tab tore apart, then blew off your roof and landed in your yard.
If that’s the case.
Where one shingle tab blew off your roof – you have a 1 in 3 chance that the missing shingle was sitting directly above an open seam between the shingles below.
That’s because standard 3-tab asphalt shingles are installed side-by-side, with the next “upper” row of shingles covering the side seams between the lower row of shingles.
If one shingle tab tears off, it’s possible that it had previously been laying directly above a seam.
And without that top shingle in place to shed water, you’ll have an unprotected gap between the lower shingles.
Exposed to water as it rains.
Water will find its way into this gap and leak under your shingles.
That doesn’t mean that you will immediately see water pouring through the ceiling into your living room.
Because… below the shingles and above the roof sheathing lies a layer of felt paper.
This felt paper may repel some of the water…
However, even with the moderate level of protection provided by felt paper your roof needs immediate attention.
Because a missing shingle left unfixed, could lead to a much bigger roof leak – especially in heavy rain.
In this case (a torn shingle above a seam), your roof will leak if you have just one shingle missing.
On the other hand.
You may have a missing shingle that does not straddle a lower shingle seam.
If that’s the case, it’s possible your roof may not leak at all.
But, your roof still needs attention, because the exposed section of the lower shingle is not designed to perform for long when this happens.
If you look closely, you will see that the area where you have a missing shingle is darker than the surrounding shingles on your roof.
That’s because the upper part of an asphalt composition shingle contains less protective mineral granules than the lower part.
These granules protect the black asphalt layer of your shingles from the damaging rays of the sun.
If you do not replace missing shingles, the lower shingles will eventually fail and leave your roof vulnerable to a roof leak.
Now let’s look at what you can do to repair missing roof shingles.
How to Replace Missing Shingles
Here’s a great video that explains the process to repair your roof by replacing a missing shingle.
In short, you will need to replace the entire 3-tab shingle that was torn, while protecting the integrity of shingles above and below the one being replaced.
PLEASE PRACTICE SAFETY: Working on a roof can be dangerous. It’s important that you have the proper safety gear. If you don’t feel comfortable with the height or slope of your roof, call a professional roofing company.
It’s important that you replace the missing shingle as soon as possible.
Again if you’re not comfortable completing the repair yourself, call a professional roofer.
It’s what they do.
A good roofing company will repair missing shingles for a reasonable cost.
And you can rest assured that your home is protected from roof leaks and water damage.
