They can be extremely low.
Flat roof homes and snow.
Of course you don t need to live in a modern house to deal with a flat roof.
Wind seismic building weight furniture occupants etc.
Don t go thinking that modern houses with flat roofs only look good though as these innovative designs actually have practical properties as well.
These are created when heat transfer from a home s interior melts the snow on a roof which then refreezes as it makes its way to the outer edges of the roof s surface.
How to inspect and maintain your roof.
Yet for historic modern style buildings like this old house s cambridge tv project flat roofs are at the core of the architecture meant to reflect the broad horizontal lines of the natural landscape.

Flat roofs can t possibly support all the extra weight a totally valid concern but rest assured your architect and engineer have this in mind when designing the roof structure.
In most flat roofed homes heated spaces are situated directly under the roof without any buffer from an unheated attic.
This can eventually cause problems with ice dams.
When it comes to maintaining your home inspection of all areas of your home should be a part of the process.
For a start there are no tricky gable end spaces to try and navigate when opening up the upper levels in flat roof houses plus you can use the roof itself as an outdoor terrace which will be a.
Certainly the weight of snow can add up but your home must support a variety of loads.
Heavy loads of wet snow can eventually lead to shingle damage stress on load bearing walls and even roof collapse.
A flat roof sits cleaner on the horizon and breaks up the scenery less.
Flat roofing is not actually flat.
If your home has a roof with a substantial pitch ice dams and clogged gutters can still prevent snow from sliding off.
It has a very low slope between 1 4 to 1 2 inch per foot so that it drains water.
But such a low slope holds snow and water much longer than a steeply pitched roof and therefore needs a very different material to stay watertight.
Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof.
Combined with the snow catching ability low and flat roofs are able to blend in with their natural surroundings quite seamlessly.
A single slope roof s typical steepness allows for easy snow and water runoff making it great for heavy snow and rain regions.
This image depicts another benefit of flat roofs.
As snow piles up all that weight equates to structural stress especially for buildings with flat roofs.
Snow is actually one of the easiest to design for and all.
That means 12 inches of snow on a flat roof creates an additional r 12 of insulation that arrives at a time of year when you most need it.
