Goff Home Inspections recommend
every household to check for the following. Every item can be
dangerous, destructive to your home and sometime very easy to
notice.
Things to Look For:
Algae: Microorganisms
that may grow to colonies in damp environments, including certain
rooftops. They can discolor shingles. Often described as "fungus."
Alligatoring: A
condition of paint or aged asphalt brought about by the loss
of volatile oils and the oxidation caused by solar radiation.
Causes a coarse checking pattern characterized by a slipping
of the new paint coating over the old coating to the extent
that the old coating can be seen through the fissures. "Alligatoring" produces
a pattern of cracks resembling an alligator hide and is ultimately
the result of the limited tolerance of paint or asphalt to
thermal expansion or contraction.
Asbestos: A common form of
magnesium silicate which was used in various construction products
due to its stability and resistance to fire. Asbestos exposure
(caused by inhaling loose asbestos fibers) is associated with
various forms of lung disease. The name given to certain inorganic
minerals when they occur in fibrous form. Though fire-resistant,
its extremely fine fibers are easily inhaled, and exposure to
them over a period of years has been linked to cancers of the
lung or lung-cavity lining and to asbestosis a severe lung impairment.
A naturally occurring mineral fiber sometimes found in older
homes. It is hazardous to your health when a possibility exists
of exposure to inhalable fibers. Homeowners should be alert for
friable (readily crumbled, brittle) asbestos and always seek
professional advice in dealing with it.
Bleeding: The migration of
a liquid to the surface of a component or into/onto an adjacent
material.
Blister: An enclosed raised
spot evident on the surface of a building. They are mainly caused
by the expansion of trapped air, water vapor, moisture or other
gases.
Blue Stain: A bluish or grayish discoloration
of the sapwood caused the growth of certain mold like fungi on
the surface and in the interior of a piece, made possible by
the same conditions that favor the growth of other fungi.
Bubbling: In glazing, open
or closed pockets in a sealant caused by release, production
or expansion of gasses.
Buckling: The bending of
a building material as a result of wear and tear or contact with
a substance such as water.
Carbon Monoxide: CO. A colorless,
odorless, highly poisonous gas formed by the incomplete combustion
of carbon.
Cohesive Failure: Internal
splitting of a compound resulting from over-stressing of the
compound.
Condensation: Water condensing
on walls, ceiling and pipes. Normal in areas of high humidity,
usually controlled by ventilation or a dehumidifier.
Corrosion: The deterioration
of metal by chemical or electrochemical reaction resulting from
exposure to weathering, moisture, chemicals or other agents or
media.
Crater: Pit in the surface
of concrete resulting from cracking of the mortar due to expansive
forces associated with a particle of unsound aggregate or a contaminating
material, such as wood or glass.
Crazing: A series of hairline
cracks in the surface of weathered materials, having a web-like
appearance. Also, hairline cracks in pre-finished metals caused
by bending or forming (see Brake Metal).
Cupping: A type of warping
that causes boards to curl up at their edges.
Damp proofing: A
process used on concrete, masonry or stone surfaces to repel
water, the main purpose of which is to prevent the coated surface
from absorbing rain water while still permitting moisture vapor
to escape from the structure. (Moisture vapor readily penetrates
coatings of this type.) "Damp proofing" generally applies to surfaces above
grade; "waterproofing" generally applies to surfaces below grade.
Decay: Disintegration of
wood or other substance through the action of fungi.
Distortion: Alteration of
viewed images caused by variations in glass flatness or in homogeneous
portions within the glass. An inherent characteristic of heat-treated
glass.
Dripping: Bitumen material
that drips through roof deck joints, or over the edge of a roof
deck.
Dry Rot: See Fungal Wood
Rot.
Feathering Strips: Tapered
wood filler strips placed along the butt edges of old wood shingles
to create a level surface when re-roofing over existing wood
shingle roofs. Also called "horse feathers."
Fungal Wood Rot: A common
wood destroying organism which develops when wood containing
material is exposed to moisture and poor air circulation for
a long (6 months +) period of time. Often and incorrectly referred
to as dry rot.
Fungi (Wood): Microscopic
plants that live in damp wood and cause mold, stain, and decay.
Incompatibility: Descriptive
of two or more materials which are not suitable to be used together.
Lead Based Paint: Lead is
a highly toxic metal that was used for many years in products
found in and around our homes. Lead may cause a range of health
effects, from behavioral problems and learning disabilities,
to seizures and death. Children 6 years old and under are most
at risk, because their bodies are growing quickly.
Migration: Spreading or creeping
of a constituent of a compound onto/into adjacent surfaces. See
bleeding.
Mud Cracks: Cracks developing
from the normal shrinkage of an emulsion coating when applied
too heavily.
Mushroom: An unacceptable
occurrence when the top of a caisson concrete pier spreads out
and hardens to become wider than the foundation wall thickness.
Photo-Oxidation: Oxidation
caused by rays of the sun.
Ponding: A condition where
water stands on a roof for prolonged periods due to poor drainage
and/or deflection of the deck.
Pop-Out: See Stucco Pop-Out.
Radon: A naturally-occurring,
radioactive gas which is heavier than air and is common in many
parts of the country. Radon gas exposure is associated with lung
cancer. Mitigation measures may involve crawl space and basement
venting and various forms of vapor barriers.
Scrap Out: The
removal of all drywall material and debris after the home is "hung out" (installed)
with drywall.
Seasoning: Removing moisture
from green wood in order to improve its serviceability.
Settlement: Shifts in a structure,
usually caused by freeze-thaw cycles underground.
Sludge: Term for the waste
material found in sump pump pits, septic systems and gutters.
Spalling: The chipping or
flaking of concrete, bricks, or other masonry where improper
drainage or venting and freeze/thaw cycling exists.
Splitting: The formation
of long cracks completely through a membrane. Splits are frequently
associated with lack of allowance for expansion stresses. They
can also be a result of deck deflection or change in deck direction.
Ultraviolet Degradation: A
reduction in certain performance limits caused by exposure to
ultraviolet light.
UV Rays: Ultraviolet rays
from the sun.
Veining: In
roofing, the characteristic lines or "stretch marks" which
develop during the aging process of soft bitumen's.
