Ice Dams- An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas.

Moisture / Mould- A flow of water that obtains as its basic source, water from high water tables, springs, etc., and can be exacerbated by  poor soils. This type of water problem can extend from the surface, down past the level of the basement floor.  This is known as an "external water source".

Proper ventilation is absolutely necessary and vital, not only to the health and well being of every home, but also to every home’s occupant. Anyone who has been in an attic knows that attics get very hot! If the heat in the attic is allowed to sit there and not ventilate, it will conduct heat into the house, or, at the very least, prevent the heat in the house and attic cavity from escaping. Without adequate ventilation, your home will encounter problems such as rapid shingle deterioration (from melting), mold build-up throughout the attic, wood rot and delaminating sheathing, mildew, peeling exterior paint, rusty nails, energy losses, and many other problems that are often the direct result of inadequate attic ventilation. Wood boring insects such as Termites and Carpenter Ants are attracted to moisture buildup that is often caused by any inadequate ventilation.
