Winter Wonderland, Well...
We've enjoyed a real snowy lead-in to winter here in the northeast. It's a welcome change to recent years when we've wondered whether or not we were going to have winter at all. A snow-filled winter beats a cold and rainy winter every time.
The most recent storm dumped another 6 or 8 additional inches on what was already about 10-12. So when news came the other day that we might get a little rain just before Christmas, we weren't so worried about Christmas not being white. We were concerned, however, about the weight that the rain would add to all that snow.
Current building codes require roofs in the north to withstand heavy snow loads, but old houses like mine, were built before there were municipal codes. And although our house is pretty well built (using 8x8 hemlock beams for a timber frame and 4x6 hemlock rafters for the roof that's covered with 1" think sheathing) it wasn't necessarily built to withstand the 50lb/sqft. snow load required by today's roofs.
You might think, well, if the roof has survived for over 100 years with all kinds of heavy snowfall, why worry about it now? The big difference between now and the last 100 years is that now the house and roof are super-insulated. Where before, the heat from inside the house would constantly escape through the roof, thus melting the snow that fell there, now the insulation captures that heat and the roof remains cold allowing the snow to stick.
Most of our roof is steeply pitched, and will shed the snow if it gets too heavy. But on the ell section at the back of the house, the pitch is not as steep. Before heading out of town for the holiday, I climbed up and went to work with the shovel.
