Siding
The
siding of a home is the "skin" or outer most visible facing on
the building. The siding on your new home is one of the most important
and possibly expensive components. The type of siding is selected
based on desired appearance, longevity, maintenance, and cost. There
are many siding types such: as vinyl, stucco, brick, aluminum, wood,
stone and synthetics. Each material has advantages and disadvantages,
which require different maintenance procedures and involve different
cost factors. Your inspector will identify the type of siding and
explain the normal maintenance requirements of each type as well
as the existing defects.
Vinyl Siding
One of the most popular forms of siding installed on new homes and used to
refinish existing homes is vinyl siding. Usually installed with planks, vinyl
siding is durable, easy to install and very low maintenance. Your inspector
will look at the installation quality carefully, making sure the planks are
not to tight which can cause buckling and that all areas are finished and
secure to prevent water penetration. A good installation of vinyl siding
has a very long life expectancy and allows for easy installation of additional
insulation on older homes under the new vinyl.
Wood Shingle
Wood shingles and wood shakes are a very popular form of siding
throughout the country. If maintained properly an installation
of this type can last many decades. Wood siding does require
ongoing maintenance such as staining and replacement of worn
or loose shingles. The installation of the water proof barrier
under the siding is crucial to protecting the exterior wall sheathing.
Wood shingle siding is a more time consuming and expensive installation when
quality materials are used. Your inspector will be carefully examining both
the quality of the material used on the installation, which greatly affects
the life expectancy, as well as the current condition of the siding. Minor
repairs or worn shingles can be replaced easily and inexpensively provided
that the areas are not too large.
Stucco
Synthetic stucco, often referred to as EIFS, consists of a polymer
based laminate that is wet-applied, usually in two coats, to
rigid insulation board that is fastened to the wall with adhesive,
mechanical fasteners, or both. Polymer based (PB) systems, sometimes
known as thin coat, soft coat, or flexible finishes, are the
most common. The base coat for PB systems is usually only 1/16
in. thick and finish coat thickness is typically no thicker than
the maximum sand particle size in the finish coat. While the
PB skin repels water very effectively, problems arise when moisture
gets behind the synthetic stucco and is trapped inside the wall.
Trapped moisture eventually rots insulation, sheathing, and wood
framing. It also corrodes metal framing and metal attachments.
There have been fewer problems with EIFS used over solid bases
such as concrete or masonry because these substrates are very
stable and are not subject to rot or corrosion. Polymer modified
mineral based (PM) exterior insulation and finish systems are
sometimes known as thick coat, hard coat, or rigid finishes.
The mineral base is Portland cement, while the polymer is usually
an acrylic. PM systems have greater impact resistance than the
PB systems, but are typically less than 1/3 the thickness of
traditional three-coat stucco.
Aluminum
Aluminum siding first began appearing on homes in the early 1960s.
This new product occasionally experienced corrosion, especially
in areas of high humidity or salty ocean winds. Aluminum siding
is still used today, but is not nearly as popular as vinyl. Aluminum
planks can dent easily and are difficult to replace. Dark colors
tend to fade in the sunlight. This type of siding does last indefinitely,
but may wear cosmetically. Cosmetic repairs to aluminum siding can be costly
Wood Plank
Traditional horizontal lap siding goes by many names. It's known
as clapboard siding in much of the East and as bevel siding elsewhere.
Whatever you call it, it is one of the most popular and durable
exterior building materials. Indeed, you'll find it in excellent
condition on American homes more than 250 years old. Though long-lived,
wood siding isn't all that tough. That's because it's usually
milled from cedar, redwood or pine - softwood species that are
easily cracked or gouged if struck by a ladder, falling tree branch or line
drive. Another common problem: The boards tend to split if nailed too close
to the end or edge, or if too many nails are used. This type of siding requires
ongoing maintenance and your inspector will be checking carefully to see
if the siding has been properly maintained.
Stone
Stone siding is perhaps the oldest siding material used in residential
construction. Found on many older homes, it is still used today on mostly
small portions of the exterior to add to the cosmetic appeal of other
building materials. Primarily only older homes have complete
stone siding installations. Stone work must be inspected carefully
for settlement and water penetration. The joints, made of cement
mortar, wear over time and must be pointed or repaired to prevent
such occurrences. On newer veneer installations the stones are
attached to the building with metal ties that keep the walls
vertical and secure. There are many varieties of stones used
for siding. Stone siding is expensive to install and almost always
requires the work of a skilled craftsman to repair if required.
Brick
Brick is a durable and appealing installation used throughout the
world. When installed and maintained properly it has an unlimited
life span. Most modern installations use a veneer type of installation
rather than solid brick. Veneer installations are a single row
thick and tied to the home with metal ties. Solid brick installations
found mostly on older homes are two rows thick held together
with a bond course visible to the inspector. Your inspector will
look carefully for proper installation, maintenance, and type
of installation. Masonry siding installations such as brick or
stone must have weep holes to allow moisture to escape. A common
mistake of unskilled craftsman or homeowners is to cover them,
or leave them out of the installation. This can cause extensive hidden
damage to the protected building components.
Cement Stucco
Cement Stucco is durable and appealing siding installation. It
can be installed directly onto cement blocks or over wire lathe.
Cement stucco should not be confused with EIFS. It is not nearly
as prone to the type of water damage associated with synthetic
installations. Cement stucco can however be prone to cracking
and surface damage. Your inspector will identify whether or not
your perspective home has a real cement stucco installation and
the condition it is in.
