Water Damage From Rain Leaks: Causes and Effects

Total Shares 0

If you recently discovered water damage from a leak in your home you may be going through a very frustrating time. Cheer up we have solutions.

Rain-related water intrusion is one of the leading causes of water damage and degradation of a home. For the most part, you may not have much of an idea of what caused the leak in the first place. But we do.

Depending on the composition of your home and the location of the leak, there can be several causes for the rain related water damage you are experiencing.

In this article we will explore rain related leak repairs you may need to hire a leak repair professional for.

About one in 50 insured homes has a property damage claim caused by water damage or freezing each year.

However, none of the rain related water intrusions are covered by insurance. Check your policy if you don’t believe me.

Water damage is a real struggle for homeowners. The statistics further expand on the actual complications of water damage and how many home owners come face to face with an issue.

Water damage is the second most frequently filed insurance claim in the United States.

Water Damage Facts for Homeowners in the USA:

  • 20% of all insurance claims are water damage related
  • Over 40% of all homeowners claimed to experience loss because of water damage
  • Billions of dollars in property loss is from water damage yearly– a good majority of this being due to rain-related issues that could have been prevented with preventative maintenance done by a water intrusion specialist.

Causes of Water Damage From Water Intrusion

There are several ways for water to cause damages to a home. The damage can be created by natural disasters, water heaters, busted pipes, air conditioning units, foundation issues and more common causes like a slow rain-related leak. This type of water intrusion is what we call the silent killer of homes.

About 93 percent of all water damage can be prevented.

Water damage from rain-related water intrusion or the “silent killer of homes”, is what we will be covering today. Since 93% of water damages to homes can be prevented, we are here to help you prevent them.

Here are some repairs you may consider need in order to prevent water damage affecting your home and investment.

Brick Repair

Brick walls are thought to be the most durable of building materials, but – given enough time and exposure to the elements – they will erode just like all stoneworks.

Brick repair and mortar repair are some of the top issues when it comes to rain related water intrusion through the wall because they will crack as a result of open lentils on windows or doors, inferior window glazing, or balcony openings from above that allow water to get behind the brick.

When brick mortar gets wet on the back side of the the wall it doesn’t have the sun or wind to dry it out. As a result the water has to leach its way through the brick mortar to get to the surface that is exposed so that it can dry. This leads to the mortar rotting and turning back into sand which then washes out and creates voids in the mortar. Thus perpetuating the endless cycle until the void is filled with a product that won’t crack back out.

When you see a crack in brick and mortar it will be a symptom of one of two things- foundation movement or rain related water intrusion. Rain related water intrusion is the most common of the two. Rain related leaks can be easily identified by a crack in the mortar that appears as a “stair stepping crack” and fractures through the brick itself near windows, doors, or intended openings in the masonry.

Brick and mortar repair is not that complicated of a fix but is crucial to maintaining structural integrity. Cracked stone brick can cause water to make its way behind the brick into the structure of the home making you need some brick restoration and leak repairs.

When you are engaging in home water leak detection to find a source of the damage, you may be surprised to conclude that it is your trusty brick wall that has sprung a rainwater leak due to inferior materials used by builders around your windows, doors, and balconies.

Chimney Leaks

As a skyward-facing opening, Chimneys can be unusually prone to rainwater leaks, and these leaks are caused by a variety of construction problems.

It may be as a result of poorly installed chimney caps, sealant problems, or gradual deterioration of surrounding brick mortar. Chimney caps have 3 different varieties, only one of which can be considered problem free- the double layered metal cap. Others are prone to rain-water leaks.

If you have a concrete cap, we always recommend to upgrade to the double layered metal cap. This would save you a lot of time, money, resources and brick damage. If you upgrade to the metal cap this is guaranteed to be maintenance free forever!

Here are a few chimney leak repairs you may be looking at:

  • Chimney cap repair (varies depending on the style you have)
  • Brick chimney repair
  • Chimney flashing repair

You can be confident that when these leaks combine with the ash and soot within the stack, the resulting leaks will be quite messy and difficult to clean up.

Roof Leak Repair

More than any other part of your home, your roof is at constant war with the elements.

When rain isn’t punishing your roof, long sunny days are causing swelling and expansion of the materials. Freezing and snow is a particularly insidious culprit putting significant weight on the roof structure.

Blocked gutters also do their part to rainwater damage because water will run over the front of the gutter like a waterfall. When the water level rises to the brackets that attach the gutter to the home, the facia board and soffit will rot behind the gutter.

When it comes to roof leak detection it can be any of the following:

  • Roof leak
  • Chimney leak
  • Flashing Leak
  • Plumbing vent stack leak
  • Transition and penetration leak
  • Mechanical Vent leak

Flashing under the shingles is particularly vulnerable because of improper installation which will leak in heavy rain events.

Window Leak Repair

Your windows are well-designed to keep the weather out, and as a particularly vulnerable part of the wall structure they are given lots of attention in the form of sealants and shielding overhangs.

However, defects in materials or improperly installed countermeasures to water intrusion may result in rather persistent and difficult to repair leakage.

Even properly applied inferior caulking and sealants are vulnerable to eventual deterioration through normal wear and tear.

Water Damage From Rain Leaks Solutions

The issues listed above are precisely why we are currently “patent pending” with our leak repair process, it creates a seal that is deterioration resistant.

After spending 25 years fixing cracks, we have learned a thing or two about stopping rain leaks completely from creating any more water damage. In that time, I invented a process that fills the crack completely and stops the leak indefinitely.

This process is why we say we are a “once and done” team. We have yet to find a rain-related leak we couldn’t stop nor a crack we couldn’t fill. If you have a leak and need some expert advice, feel free to contact me, Terry. I love educating home owners and helping people prevent water damage.
