Is Weather-Proofing a Fall Home-Prep Essential?

There is a myth going around that “weather-proofing” your home consists of caulking every single spot that allows air in. We have explained in a previous article that this concept isn’t exactly correct.  There is a natural exchange of vapor, moisture, and temperature that occurs within every healthy home.  If we didn’t have this exchange, carbon monoxide from our breathing would build up - not to mention mold and other nastiness would develop from trapped moisture.

That said, it’s still okay to protect your family and your energy bills from unnecessary drafts and drips.  Here are several ideas for keeping your home weather-proof, starting from the top down:


The Roof:

There are three huge protection factors for your roof.  

First is the roof structure itself. That is, the shingles, underlayment, wood base, etc.  These all need to be in place solidly, with no missing/damaged pieces (like a missing shingle or rusty flashing.)

Second are your gutters.  These are the pathways your roof uses to shed water.  When your gutters back up, puddles of water will sit on your roof and can get under the shingles.  Also, if your gutters are broken, water will run beneath your eaves, causing leaks.

Third is your roof ventilation system.  The air beneath your roof (like in your attic) shouldn’t sit and become stagnant.  It should be made to move and exchange with fresh air.  This stops moisture buildup and prevents the roofing materials getting damaged from inside your home.Sept 2014 Blog 4   Pic 2


The Vents:

Obviously, ventilation is important.  Your home needs to have the ability to exchange air from outdoors with the air inside.  There are a lot of modern ventilation devices which work to do this without too much change in temperature.  Two very basic ventilation systems many houses have are exhaust systems and supply systems.  In other words - systems that get rid of the air existing in your home and systems that draw in new air.  Such systems are important to maintain and keep clean.


The Windows:

There are some very simple things you can do to keep your windows from letting air in when they are closed.  First, you can install double-paned windows.  These help insulate your home, reduce noise, and are usually pretty easy to clean.  Another idea is to install weather stripping at your windows.  This can keep drafts from whistling in through any cracks when we get that chilly or windy Bay area weather.

Old vinyl or aluminum siding can actually trap moisture against your home, resulting in rot and mold.  Get your siding checked out and replaced as needed with modern, fiber cement siding.  Fiber cement siding works to allow the home to breath properly - keeping it dry.  Cedar and other wood siding works similarly - but fiber cement siding is easier to care for and can last longer than wood siding.


The Doors:

Much like windows, doors traditionally let in cold air - even when they are closed.  You can install weather stripping at the base of your door to keep the cold air from leaking in.  If your door is extremely old or has warped it might be time for a whole new one.  If you suspect damage to your door and/or to the whole door frame, be sure to get it checked out before winter.  That simple replacement could save you a ton in electricity bills and is a pretty simple and green home improvement.


We are sure looking forward to the end of summer and the onset of cooler weather.  What about you?  What’s your favorite season here in San Mateo?
