Important terms to understand

Before we discuss the signs of roof leaks, let me introduce you to roof shingles. Because, we cannot talk about roofs without knowing what roof shingles are. This is what the entire outer part of your roof is made of. Several roof shingles arranged in a professional manner.

So,

What are roof shingles?

Generally, roof shingles can be defined as the covering of a roof, consisting of flat, rectangular shaped individual units that overlap. When you look at your roof, you’ll see how these shingles are placed. In layers, one on top of another overlapping from the edge of your roof going upwards.

Also note that roof shingles are made out of small colored chips called granules. It is these granules that give your roof its pleasing look.

In a nutshell, granules are the major components of roof shingles, which form the outer visible section of your roof.

Now that we already know what roof shingles are. And we are also familiar with what a granule/ granules is.  Let’s jump right in to our main topic of this discussion: the signs of roof leaks to always be on the look-out for. The exterior and interior signs of roof leaks.

Exterior Signs of Roof Leaks

  1. Granule Loss

We have already defined what granules are. And, since these are the major components of your roof shingles, it goes without saying that- when they are lost, your roof deteriorates.

Granule loss takes place over time due to the natural processes of wear and tear. The colored chips (granules) come off and your roof shingles start to disintegrate.   When this starts to happen, the efficiency of your entire roofing system is reduced. And, you are left at risk of experiencing roof leaks.

You’ll also notice the pleasing look your roof once had fading away.

How can you be on the look-out for granule loss to prevent roof leaks?

Inspect your gutters regularly to see if they are filled with shingle granules

As your roof ages, the granules get weaker and easier to separate. Then, when it rains or a storm happens, the shingles come off and might end up collecting in your gutters.

So, if you see shingle granules collecting in your gutters, purpose to inspect your entire roof as well, to check if there are any repairs needed. Because, granule loss is a clear signal that your roof might need repairs.

Particularly, look for any bald or smooth spots on your roof. Such spots indicate that most of the granules have already come off. Meaning, you now have shingle damage which weakens your whole roof system exposing it to roof leaks.

Replacing the shingles as soon as you can is the best way of handling shingle damage. However, before you do this, there are 2 things you should do:

  • Check your manufacturer’s warranty.
  • Call a trusted residential roof repair expert for their professional opinion on the extent of your shingle damage. This will help you decide a good way forward- whether to just repair or completely replace them.
  1. Blistering, buckling, curling, cracking & Missing shingles

I will explain each of the sign mentioned in this point separately. Because, they mean different things even though all these damages happen in one place, i.e. – on your roof shingles.

  • Blistering

– Blistering happens when bubble-like swellings called blisters form on your roof shingles. With time, these blisters lose their bubble cup leaving pitted marks on your roof.

   What causes blisters on roof shingles?

Mostly, roof blisters appear when there is excessive heat coming from roof systems that are overheated. Or, just ventilated poorly. Blistering shortens the overall service life of your shingles.

  • Cracking

Cracking happens when radiation from the Sun’s U.V rays damages your roof shingles from inside. Also known as thermal splitting, cracking can be described as the tearing of roof shingles. Your roof shingles literally split into two or more pieces.

Tearing or splitting may occur horizontally, vertically, diagonally or at the corners of roof shingles. This is the principal problem affecting fiber-glass based asphalt shingles currently.

At first, cracking was often observed on 15-year life (the lightest-weight) shingles. But, overtime, it has been seen across shingles of all styles and life- ratings (weights). We will discuss what shingles’ life-ratings means. And how this affects the overall life-cycle of your roof in another article.

For now, keep paying attention to our main topic of dicussion- knowing the signs of roof leaks to be watchful for.

Cracking may also happen easily depending on the manufacturer of your roof shingles. When they produce defective asphalt shingles. This was especially common in the United States, across several manufacturers during the early 1990’s.

Tearing happens easily on asphalt shingles that are defective because of rapid thermal expansion and contraction. During hot weather and when cold weather approaches, respectively.

  • Buckling

You can easily know when your roof starts to buckle because it will appear as though there is something beneath the shingles pushing them upward and outward.

What are the causes of buckling roof shingles?

There are two major causes which are very common

  1. Improperly applied felt  
  2. Frequent movement on your roof-deck

Generally, buckling shingles are a major indicator of roof water problems. Because, they can easily lead to roof leaks. Also, they expose your roof’s wooden portions- those lying beneath the roof shingles- opening them up to deterioration and rotting.

When this happens, ensure to contact a well-certified roof expert right away. For their professional opinion which will generally guide your course of action.

  • Curling

When your roof shingles curl, they lift upwards in a somewhat spiral or winding manner. Mostly, you’ll notice your roof shingles start to curl from their edges.

There are several reasons why your roof shingles curl as you will learn in the article.

  • Missing shingles

In this case, your roof shingles come off completely.

When your roof shingles go missing, you’ll notice bald patches spread haphazardly all over your roof. The major cause of missing shingles is high wind speeds and storms. Whenever roof shingles are not fastened properly, they come off and are easily blown away during storms and high winds.

  1. Algae and Mold Growth

The growth of algae and mold on your roof shingles is a clear warning sign of potential roof leaks. Roof algae and mold is common in climates that are warm and humid.

Southeast United States is a good example of an area with a warm humid climate where roof algae and mold grows rampantly. Moisture in the air combines with airborne fungi/mold that is deposited on your roof causing it to grow aggressively.

  1. Damaged Flashing

Generally, flashing is thin pieces of impermeable material set up to prevent water from passing into a structure through a joint. As part of a barrier system that is weather resistant.

Damage to your roof flashing happens when the material becomes loose or deteriorates completely.

Depending on the material you use, your roof flashing  can deteriorate easily due to weathering or oxidation. Oxidation is just a fancy name given to the chemical process that takes place for rusting to occur. When your roof flashing gets damaged, your home is left exposed to potential roof leaks.

What is the purpose of roof flashing? And, how does it work? Follow this article to get more roof flashing details.

  1. Rotten Roof

Anything that is rotten is bad for your health. Imagine having a rotten meal. Not once, twice but several times. What do you think will happen to your body in the long run?

In the same way, a rotten roof affects the health and wellness of your home while threatening your family’s safety and wellness as well. The wooden parts of your roofing system start to rot when the mat is left exposed to moisture for long.

When this happens, your roof mat starts absorbing the moisture, allowing fungus to start growing rapidly. With time, the wood underneath deteriorates and begins to disintegrate.

A sunken roof deck is one of the most common indicators of a rotten or rotting roof. Therefore, if you notice a section of your roof appearing uneven or bowed, contact a roofing expert without hesitation.

Roof rots are better handled sooner rather than later. To minimize the potential damage on your entire roofing system. And, save on the overall cost needed when it comes to roof repairs. You can easily notice your roof deck sinking when you check inside your attic.

  1. Spots of Water on the outside of your walls

When you see these spots, take note that there might be water damage to your step flashing. e. the place where your roof meets the rest of the wall.

Depending on the material that has been used, your step flashing becomes loose or completely rusts with time. This allows rain water to cause damage to your roof and walls.

Replacing your step flashing is the best way of mitigation. You can do this yourself or seek the help of a professional roofing company.

Interior Signs of Roof Leaks

  1. Water Spots on your roof ceiling

This is a clear indicator that your roof might be leaking in one way or another. Usually, it is much harder to locate the source of a small leak compared to a big one, on your roof.

The main reason being, small leaks shift positions from their point of origin. And, can literally happen at any part of your roof. This is different from big leaks, which are pretty easy to locate since most occur from visible damages on your roof.

If you notice any water marks on your ceiling, contact a certified residential roof repair service company for help.

  1. Spongy or very soft wood decking

Such damage on your wood decking signal long-standing water damage. The softness/spongy-ness happens due to rotting which leaves your roof open to potential leakage in the near or far future.

It is important to note that walking on soft wood decking in very unsafe. Such areas should be avoided completely until proper repair work takes place.

  1. Water damage problems in your attic
