Routine
Inspection
According to the National Roofing Contractors
Association/Asphalt Roofing Manufacturers Association
(NRCA/ARMA) Manual of Roof Maintenance and Repair,
the greatest cause of premature problems on flat
roofs is the failure to find and correct minor
defects and deterioration in their early stages.
Inspections by volunteers or building staff should
take place at least twice a year, preferably in
the spring and autumn, recording and reporting
all changes in the condition of the roof. Look
for the following conditions: roof surface problems
such as blisters or bubbles, worn surfaces, open
seams, visible cracks, ruptures or other holes,
and loose surfaces or fasteners; drainage problems
such as standing water, clogged drains and gutters,
and bent or missing drain covers; flashing problems
including cracks, holes, rust, missing flashing,
and failed caulking at joints between flashing
and parapet walls; masonry problems on parapet
walls such as deteriorated mortar joints, brick,
and coping stones; and accumulation of debris
such as old roofing materials and household rubbish.

It
is also important to check the roof during and
after a heavy rain to see how water is being drained
away from the building and if gutters and leaders
are clogged. In addition, check the underside
of the roof, especially the edges, from the attic
for detection of leaks.
Should a problem be discovered during inspection,
the correct diagnosis and its prompt repair will
save money by prolonging the life of a roofing
system. Repair punctures, worn bituminous coatings,
open seams, failed flashings, and other problems
before serious leaks develop. Once a roof leaks,
damage to the building becomes costly to repair.
For example, wet insulation boards and rotting
decking require roof replacement. If an accumulation
of water is discovered, a roofing contractor can
increase the slope of the roof by installing insulation
boards over the wood decking.
Standing water (also called ponding) is a sign
of drainage problems. Leaks will occur if there
are any defects in the roof membrane or flashing.
Any temporary in-house repairs or professional
roofing work should be completed before winter.
Some temporary repairs to roll asphalt or modified
bitumen roofing can be performed by maintenance
crews or volunteers. However, it is important
to avoid the indiscriminate use of bituminous
patching compounds (such as roofing tar) for repairs.
These temporary repairs can be harmful to building
materials and difficult to remove at a later date.
Flat roofs are frequently used as platforms for
mechanical equipment, signs, and braces, where
improper mounting and flashing causes leaks. Avoid
using the roof as a staging area for parapet,
steeple, or mechanical repairs, where workers
can be careless about protecting the surface.
When
to Repair or Replace?
Many congregations try to extend the life of a
flat roof by continually repairing the surface.
This decision may ultimately cost more in the
long run due to increased staff attention and
damage caused to interiors and structural systems.
According to the NRCA/ARMA Manual, roof replacement
is recommended when the roof has exceeded its
expected service life and shows evidence of advanced
deterioration: insulation is wet, deteriorated,
or poorly attached; or numerous leaks of a serious
nature have developed in the roof membrane. Replacement,
rather than recovering the old roof with a new
membrane, is also necessary when the existing
roof membrane is not a suitable substrate for
a new roof covering, or two or more roof coverings
already exist.
