Layers and Layers
Keeping a house dry inside is complicated. As the outside temperature warms & cools part of a house contract and expand thus it is very easy for cracks to form that will let moisture inside. We make a home water tight by wrapping the structure in layers with special joints when needed. Here we see tar paper on the roof an an underlayment to the shingles that will be the top layer.
