Home Tip: What does snow melting on my roof really mean?

One of the biggest perks of being a Realtor is the privilege to attend dozens of building inspections per year!  It is a continued source of learning and knowledge for me. The beauty of my blog? The ability to share the little nuggets of home wisdom that I pick up along the way!

Needless to say, it has been a wild and wicked winter here in St. Louis!  Snow days have been aplenty and almost ALL of my inspections thus far in 2019 have been in the snow, including yesterday's.   As we approached the property yesterday, before even entering, the inspector blurted out "Alert Carrie- we need insulation!".

How did he know that, you may ask, before even entering the property?  On the north-facing entry of the home, despite frigid temperatures, the snow was melting off the bulk of the roof EXCEPT above the unheated garage.  Hence, heated air is escaping in to the attic and warming the roof.

Insulation has already been a topic that I have blogged about this year, as we recently did some MAJOR addressing of deficiency in our own home.  While as a real estate professional I should advise it is prudent and due-diligence to climb a ladder and regularly check your insulation levels, realistically, most people only venture in to their attic if necessary.  Hence why this tip is INVALUABLE to Homeowners as it is easy and fool-proof!

Plain and simple, a snow-covered roof means that your attic is doing its job. Patches of uneven melt are a sign of heat loss. If your neighbor's roof has a thick blanket and yours doesn't, it is a sign of heat loss.  Steam coming off the roof on melt days- a sign of heat loss.  Icicles forming on the gutter line are also often a sign of heat loss.  If your roof is warm enough to melt the snow but it's cold enough outside for snow to refreeze, your roof is losing heat.  Period.

HOMEOWNER TIP: 
In the days that follow a snowfall, examine the roof on your home- preferably the North-facing side. If the outside temperature stays below 32 degrees, there should still be a healthy sheet of snow on your roof. If you notice patches where the snow is melting (or any of the signs mentioned above), your attic is likely lacking proper insulation OR the insulation has been shifted during home repairs and is no longer evenly blanketing the attic floor. These areas of leakage will not only melt the snow, but it will cause your heating bills to rise and affect your home comfort.

Address the problem now so your pocketbook and furnace don't have to work so hard! You will be cooler in the summer and warmer in the winter.

LOCALS:
Curious about the cost of adding additional insulation in St. Louis?  In our personal project, we blew in insulation to a maximum R60 level (from 21ish) using premium 85% Recycled Green Fiber, which also creates a sound barrier and is fire retardant with zero fiberglass.  For just under 2000sqft, it was approximately $2,500.  In just 2 months, we have already seen our heating bill drop tremendously, despite frigid temperatures.
