When i went up into the attic to take a look i discovered the problem.
Attic looks like snow.
However metal roofing is surging in popularity as more aesthetic options become available.
Now there are metal shingles and panels that imitate materials like slate tile wood shake and even asphalt.
Icicles may look pretty but they could also be a sign that something is seriously wrong with your roof.
Most of the insulation in that area was sopping wet and had absorbed the water like a sponge.
Since the construction is quite simple with fewer materials needed this helps to keep the cost of a roof down.
Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation.
These dams form when snow covers the roof and rising heat melts only some of it causing liquid water to flow down the roof.
The gambrel only uses two roof beams along with gusset joints.
What s the difference between an asphalt shingle and metal roof.
However once it s away from the heat the ice freezes again.
Seals blowers and motors last longer when fiberglass is used.
Less attic dust fewer dust masks and improved attic visibility.
If you can see a dip curve or swag on the peak when standing in the street your roof has a problem.
A hot ceiling tells you that the attic is acting like a solar oven raising your cooling bills and cooking the shingles.
Which would go along with my thoughts on the big vent.
Much like the mansard the gambrel provides extra living space for a garret attic or loft.
And it was melting fast.
There was about 3 inches of snow resting atop the insulation extending 4 feet away from the vent.
Warm air that escapes rooms below gets trapped in the attic.
Asphalt shingle roofing is a dominant material for residences.
Fiberglass is easier on installation equipment.
Steepness playing a factor in the range and how high the ridge is set.
Plus it s simple to frame out.
Equipment also stays cleaner.
7 the m shaped roof.
The ridge vents are designed to cover the gap at the top of the roof much like the hat you wear in the rain it is designed to keep rain and snow out under normal conditions.
The roof vent in pic 5 post 1 does not look like a standard roof vent.
Customers like the snow like look of modern fiberglass.
Plus it is possible for snow to build up on the top slopes which are not easily accessible.
Looks more like an fan exhaust roof termination.
Gambrel frames are nice for sheds or even garages.
Snow melts and the water refreezes on the cold eaves creating ice dams.
What causes a sagging roof line.
Looks more like lots of condensation.
From what i am seeing in pic 4 post 1 i don t think you have snow coming in.
Unfortunately if things aren t quite right with the vent and the weather conditions are right you can end up with attic snow.
Roof lines should be arrow straight.
