Ice & Water Protection

 

Typical Ice & Water
Protection Installation

What is it and what does it do?

As part of our standard installation, heavy-gauge felt
paper is installed underneath to protect your roof from
typical moisture buildups that occur throughout the year.

However, an optional ice & water protection made of
layered, neoprene rubber can be installed underneath
the felt and shingles in those areas most prone to 
snow buildup and “iced-damming.”

Along with proper attic ventilation, the added ice protection
can  help prevent wet insulation, water-damaged drywall
and stained ceilings.

The idea is quite simple. In a typical ice-damming
situation, snow that has built up on the roof begins to
melt from the underside, the result of heat being lost
through the home's attic. As this melting occurs, the
water runs along under the protective snow layer until it
reaches the eaves and overhang at the edge of the roof.

It is at this overhang where there is no more heat being lost from inside the house,
the water freezes and forms a dam of ice, backing up more snow melt behind it.

Eventually, the dammed up water can work its way back up the roof and under the
shingles, wetting the attic insulation and ceiling drywall.

The ice and water protection layer covers this vulnerable area from the end of the
eaves to above where the roof intersects with the outside walls. The rubber layer
has no seams or openings, and tightly grips any roofing nails or staples that are driven
through it, sealing the fasteners and forming a continuous protective barrier against ice and water migrating or dripping into the attic.

The rolls are three feet wide, which is wide enough to cover the overhangs on a 
typical house and reach up past the roof/wall intersection. In houses with very wide
overhangs or covered porches, two or more overlapping layers of ice and water
protection are used – whatever is necessary to get up past the line of the exterior
walls.  This material is also excellent for use on low-pitched roofs in areas such as
porches, sunrooms and shed dormers, and as additional protection in valleys and
other particularly vulnerable areas.
