Homeowner tips for dealing with Ice Damming

Thursday, February 11th, 2010

Unfortunately for many of us, due to the heavy snow load, we will experience water infiltration at our rooflines.  This will occur more than likely due to “ice damming”.  Ice damming is caused when the snow and ice sitting on the higher portions of the roof begin to melt.  Since hot air rises, the higher parts of the roof will melt first, while the lower portions will remain cold.   As the water freezes, the ice clogs the gutter and forms a “dam”.  The are a few things that you, as a homeowner can do to help/prevent this problem:

1.  Inspect attic every 4-6 hours to look for water

2.  Use snow rake/step ladder and rake to rake snow in downward motion off roof

3.  Pour calcium chloride (salt) lightly into gutters to melt ice.  Do NOT get ANY on roof shingles, as it will eat away at shingles

4.  Aim a fan in attic directly at area where leak is coming from, at higher portion of roof.  This will cool the warmer air/section of roof and help prevent snow/ice from melting

Lastly, if you still see water coming through roofline, do not panic.  Put buckets/towels under areas to prevent collateral damage.  Remember that homes and building codes in the Mid-Atlantic are not made for 4-5 feet of snow in one week.  Once the snow has all melted, use a fan to dry out the wet areas.  There should not be any permanent damage done.  For any greater concerns, contact a roofing professional for an inspection.

How to handle heavy snowload on your roof

Tuesday, February 9th, 2010

Most homeowners in the Mid-Atlantic are not accustomed to blizzards of this most recent severity.  Here a few tips to help you and your home survive this recent onslaught…safely.

- First, NEVER go on your roof!  A roof built in the Mid-Atlantic can typically hold 20-25 lbs/ square foot of snow load.   Depending on the  amount of moisture in the snow (1-33%), 20 inches of snow can equal 25 lbs.  Your weight, which is not evenly distributed, can cause collapse.

- Second, if areas of roof accumulate greater than 2- 3 feet, use either a snow rake or a step ladder.  Again, do NOT go on roof.  Always rake in a downward fashion to avoid destroying roof shingles.

- Third, do NOT use salt or calcium chloride on roof, as chemical will destroy shingles and void roof warranty.

If you notice bowing or roof from inside home, or hear cracking in the roof…evacuate immediately and call a professional.
