Does
your client want a common technique
for assessing the serviceability of
his roof? Tell him to consider the
overall physical condition of the
roofing material.
Of
course, there is an easier
way. Simply ask him, "Does
it leak?" But don’t count on
that approach addressing all concerns.
The best case scenario, one
in which the roof’s overall physical
condition is evaluated, is
the approach taken by
professional home inspectors
and roofing contractors.
Replacement is routinely recommended
for damaged or
deteriorating materials whether or
not leaking has occurred.
Actually, the "does it leak" approach may
do more harm than good. First, it assumes
that, because a roof hasn’t leaked yet,
it won’t. (Let’s face it — there’s always
a first time!) This approach is often
used by those attempting to avoid paying
for a new roof, but they’re only postponing
the inevitable – and may make
the situation (and the costs) worse by
the wait.
Home sellers shouldn’t ignore the signs of a
failing roof – and home buyers would be
wise to check them as well. By waiting for
the water to break through, sellers risk
damage to walls, ceilings, and exposed
furniture. This is one case in which
"nip it in the bud" not only applies,
but is really the cost-efficient approach.
A professional home inspector may
be able to report on the shape of roofing materials,
particularly if they are noticeably worn
or damaged. However, a licensed
roofing

contractor
is better prepared to make a conclusive
evaluation of the roof and
its condition.
For example, an inspector may determine that
the roof shingles are curling, which may
be a result of substandard
manufacture of the
shingles or, more often, inadequate ventilation
of the attic. If the attic isn’t
properly ventilated, it can become extremely
hot during the summer months,
causing shingles to become dry and
brittle over time.
If such a problem is identified, the homeowner should
inspect the attic vents to ensure
they are clear of obstruction. Light
from the attic should be visible. Sometimes
eave vents can become blocked
with insulation. And low clearance in
the attic makes the insulation removal
difficult.
An easier solution is to install additional vents.
Turbine vents near the roof ridge should
meet or exceed current ventilation requirements.
Of course, a licensed roofing contractor
can best determine the roofing
problems — and the best solutions for
a particular dwelling.
