The use of rigid plastic foam sheathing is also becoming more common in residential construction. If you tuck window flashing under the foam sheathing you may create a leak. As described above, water collects on the top of windows and is forced to the window's edge where the flashing leads water beneath the foam. The flashing is installed over the foam and the foam is notched to receive the top of the flashing. Corners Not all leaks result in water dripping on the carpets of nervous clients.
Some leaks slowly compromise the structural integrity of a building.
Rip off the corner boards of enough old houses and you will see your share of rotting corner posts. In general, corners of buildings experience the greatest effects of wind pressure. Special care should be taken to protect this area from exposure to rain water. Last month I had the opportunity to visit the construction site of a very expensive new home. The quality of construction was unsurpassed by any crew I have seen.
