Is My Siding Waterproof?

Amidst all the rain we’ve had recently in Maryland, many homeowners are asking themselves this question. Today, we’re going to focus on vinyl siding, which is a waterproof material—when installed correctly.  There are also a few other precautions you (and your installers) can take to protect your house from unwanted moisture. Here’s what you need to know:

 

1. Start at the Bottom

 

Since gravity naturally pulls water downward, we install siding from the bottom up.  That way each strip overlaps the other in a way that encourages water to run off the side and away from your interior.  We pay special attention to doors and windows where there tend to be fewer layers, as well as the placement of trim, by starting with these pieces first.

Having an experienced installer makes all the difference with this process, since changing the process method or doing it poorly can create gaps in your siding.  Each gap presents an opportunity for moisture to enter your home—either because of humidity or outright rainfall—and energy loss. So, working with the trusted team at Schaefer Exteriors can help to waterproof your home.

 

2. Accessorize

 

Did you know that the special pieces installed alongside the corners of your siding are called accessories? Much as we start “backward” when placing the regular strips, a good installer will lay these (and the trim) flush along your house first.  Not only does this help to prevent water from running under the vinyl, but also it gives the overall effect a more finished look by covering the cut ends.

If you live in a place known for serious storms and/or high winds, we can take this a step farther by using lap joints in an opposing direction.  Lap joints are especially important for larger homes that require more than one piece of siding; they allow us to overlap multiple pieces horizontally.  By starting on the wall farthest from the prevailing winds, we can minimize the amount of rain blowing in between strips.


3. Moisture Barrier

 

Depending on where you live, building codes or HOAs may require you to have this in place already. Essentially, this is an extra layer of protection in between the house boxing and your new siding.  Because even the most effective installation isn’t 100% waterproof, this barrier will prevent rain or other moisture from touching your home, should it make it past the vinyl strips.  Be sure to ask us about house wrapping, too, when having your exterior updated, which can improve your energy efficiency.

Given the recent weather forecast, it’s natural to wonder about the water resistance of your house.  Our experienced team can advise you on solutions that fit both your budget and your surroundings.  While we can’t waterproof your home completely, our expert installation of new vinyl siding can get you pretty close!
