DC and the Mid-Atlantic Snow Leads to Roof Ice Problems

by

I just wrote about this in the Northeast several weeks ago.  And now, this weekend’s Mid-Atlantic snowpocalypse hammered the region around DC for hundreds of miles with two to three feet of snow.   Northern Virginia, DC, Baltimore, and further up the Atlantic seaboard are covered in a blanket of snow.   Snow on rooftops often leads to problems with icicles and ice damming, as we’ve discussed here before, but primarily for homes with air leakage into the attic and poor insulation. (Some will tout inadequate ventilation as the cause—but roof ventilation is often insufficient, it can make energy leakage worse, and it’s possible to solve this issue with no roof ventilation!).  The snow, while creating havoc, also provides an opportunity for homeowners to look for problems as shown with this series of photos from Vermont. 

Everyone in the region, good luck shoveling out.  Be safe.  And if you’re having ice issues now, think about upgrading insulation and air-sealing after you dig out and things get back to normal.  You’ll be more comfortable and save energy in the long run.  And remember, federal tax credits (and many local programs) can help you pay for the needed upgrades.

Thanks,
Mike
