Will Your Roof Leak With One Shingle Missing

missing shingles

When severe weather strikes and a tree comes crashing through the top of your roof, it’s pretty obvious that you need to have some repairs done. But what about more subtle damage? Perhaps, I don’t know, a solitary missing shingle? Homeowners have long wondered where the threshold lies for repairing their roofs and today we’re going to find out!

Damage caused by roof leaks

Mold and mildew

One of the main issues with any roof leak is the possible growth of any mold and mildew. Whenever moisture is present, the potential for mold or mildew developing is a given.

While the regular variants are bad enough, the last thing you want to see is the development of black mold. Black mold is classified as a neurotoxin and can lead to internal bleeding in the lungs.

Beyond the serious health risks of having black mold and its spores present in your humble abode, the removal of this scourge is also rather expensive — which is why roof leaks are the type of issue that you want to nip at the bud whenever possible.

Electrical hazards

Since we were children, our parents would always warn us that electricity and water should never mix. It’s the age-old recipe for disaster. The average home is riddled with various electrical fixtures.

From internal wiring and wall sockets to circuit breakers and fuse boxes, it’s hard to look in any direction in your house without seeing something electrical. That being the case, you should be very careful in spotting roof leaks early before they become so severe that the moisture reaches electrical fixtures as these could pose both a fire hazard and a shock hazard.


While the number of wet floor signs in your local McDonalds may seem excessive, we can assure you that they’re there for good reason.

Slipping is often regarded as a minor threat, but it can actually be a real danger — especially if you have children or elderly in your house.

While a minor fall may not be too noteworthy for the average healthy adult, a single tumble could lead to a stroke if the person falling is entering their golden years.

Causes of missing shingles

Wear and tear

The main cause for missing shingles is normal wear and tear. Nothing lasts forever. Most roof shingles can last for a good couple of decades before they start to wither away, and other shingles that are made out of heavy-duty materials may last even longer.

Still, even if you use the best materials on the market, your shingles are bound to lose their edge at some point. If you notice that the grip strength of the adhesive used to keep your shingles in place is gradually weakening, you might want to have a professional inspect your roof so that they can replace any shingles that are at risk of coming loose in the near future.

Improper installation

If you’re noticing missing shingles in a roof that’s relatively new, there is a high likelihood that the issue is due to improper installation. The application of adhesive and sealing of your shingles is a crucial point in the installation process.

If someone were to rush through it and not take proper measures to ensure its longevity, you could see shingles coming loose soon after its initial installation.

Best roofing materials


While metal roofing may not be the prettiest option — nor the quietest during rainstorms — it will definitely last way longer than wooden shingles. Depending on the type of metal used, the average lifespan will generally range between 40 and 80 years.


If you want something that will last long while still looking good then you should consider investing in a good set of clay shingles. They’ll be a fair bit more costly than their metal counterparts but with a lifespan of 100 years and pleasing aesthetic, they’re well worth it.


If you want to get to that 100-year lifespan without breaking the bank then you could go for clay’s cheaper cousin — concrete. Concrete roofing can last just as long as clay but will cost you far less making it a great option for low-budget remodels or renovations.

The big answer

So, here’s the answer to the question you came here with: will your roof leak with one missing shingle? Well, it actually varies from case to case. Depending on the structural integrity, age, and health of the surrounding shingles on your roof you might not even get a leak at all if you’re only missing one or two shingles.

That being said, you really shouldn’t take the chance. It might seem like an unnecessary expense to replace a sole missing shingle, but the cost of repairing property damage from roof leaks will be far more severe.
