Water Damage Behind Vinyl Siding

Vinyl Siding Can Be Protected From Water Damage When Gutters Are Installed.

What happens if water gets behind vinyl siding?

Vinyl siding is often a good choice for protecting the exterior of your home. Vinyl siding itself is rarely if ever damaged by water. That said, vinyl siding also is not 100% watertight. When it is installed there may be gaps and overlaps present that can allow water to seep behind it.

When water gets behind vinyl siding it can damage the interior walls, as well as to the foundation. Water damage can include everything from causing the sheathing to rot to mold growth. The water can also damage the foundation and insects might feel free to take up residence inside the walls.

Often, when water seeps behind vinyl siding, the first thing people will notice is something that looks like dirt inside the home, usually near the window. This is a sign of moisture penetration from outside the home.

One key way to keep water from seeping behind your vinyl siding is through gutter installation in Crystal Lake and Schaumburg, IL. Gutters are vital to draining water away from your vinyl siding and away from your home. For quality gutter installation, you can rely on the professionals at Expert Roofing.

Storm drain cleaning is also an effective tool for keeping water and debris away from the house by keeping storm drains clear of clogs.

Should I caulk my siding?

While you can use caulk on siding to seal areas like corners or crevices to prevent water from seeping in, it might not be wise to do so, depending on the type of siding you have. It is better not to use caulk on vinyl or wood siding because both types of siding expand and contract with temperature fluctuations. Caulk can stop this type of siding from necessary expansion and contraction. If you have fiber cement siding, caulking is often unnecessary because flashing is usually installed underneath it to serve as a way to waterproof the siding. Adding caulk prevents the flashing from draining water away from the house. Caulk only if the flashing is not present.

Do I need house wrap behind vinyl siding?

Most contractors believe house wrap needs to be installed behind vinyl siding. This is because vinyl siding is not 100% watertight. House wrap is specifically designed to prevent air and water leaks that seep past the vinyl siding. In other words, house wrap serves as a barrier against water damage caused by any moisture that gets behind your vinyl siding.

Is vinyl siding watertight?

The simple answer is “No.” Vinyl siding is not completely watertight. The way vinyl siding is installed leaves gaps where water might get in. But, it’s also preferable to install vinyl siding loosely so it can properly expand and contract as outside temperatures fluctuate. The siding can become damaged over time if it is unable to expand and contract properly.

Does vinyl siding rot?

Although dry rot is common with fiber cement and wood shake siding, it’s also possible for vinyl siding to rot. If there are high levels of moisture behind the vinyl siding, a fungal growth that causes dry rot can develop on the wood behind the siding. This growth can also cause the vinyl siding to rot. Rotten siding can be detected by tapping it with the rubber handle of a tool. If dry rot is present, the vinyl siding will break apart after it is tapped.
