Roof Repairs can be an option for prolonging the life of your overall roof system.
Many factors will come into play such as:
Common roof system failures may be repaired if the cause is ascertained and
proper roof repair methods are followed.
Flashings: Flashings must be installed per the manufacturers' installation guidelines.
Flashings divert water around chimneys, end walls, and skylights. When flashings fail or are
improperly installed, water will find its way under your shingles, tile, or metal roof.
Flashings are made out of galvanized metal, copper, and aluminum. Some skylight flashings
are made out of a flexible composite material. Lead flashings are unadvised due to squirrels
and other rodents that damage them.
Asphalt Shingles: Shingles will eventually experience granule loss. These granules are
typically made out of limestone. Granules help to protect the asphalt shingle from
degrading due to the sun's ultraviolet rays. High winds, people walking on shingles, and
algae contribute to granule loss. Click HERE to see more about granule loss. Shingles may
blister or crack due to large temperature changes. Improperly ventilated attic spaces
contribute to shingle failure and also void manufacturers' warranties. The Department of
Housing and Development has issued minimal ventilation requirements for FHA. The ratio of
the total net free ventilation area to the area of the ceiling shall be not less than 1/150, except
that the ratio may be 1/300 if: certain conditions are met. Shingles may delaminate or un-bond
from each other due to manufacturers' defects or high winds. It is imperative to follow
manufacturers' cold weather installation instructions to insure proper bonding of the shingles.
High Wind nailing patterns should always be followed.
Improper Decking: Decking whether it is plywood, OSB, board, or insulation board, must
provide for positive drainage of the roof system. Ponding that occurs will almost certainly find
its way into the roof system. No roof system should be considered waterproof, but rather
water shedding. Improperly nailed decking and incorrect decking can contribute greatly to its
premature failure. Decking sizes and nailing patterns are governed by building codes.
Metal Roofing: Metal roofing failures typically involve coating and fastener failures.
Metal when installed near salt water should be coated by the manufacturer to their saltwater
guidelines. Screws have different life expectancies also. We find that the rubber washers tend to
fail after several years and lead to water penetrating the roof system. We offer re-screw
installations using WoodZAC screws.
Membrane Failures: The leading cause of failures are improper penetrations, improper heat
welds, and foot traffic. Penetrations should take use of the proper membrane flashings. Doing
inspection patches along welds will insure proper bonding. The use of specially designed foot
pads will reduce the wear and tear on your membrane roof. Repairs can include patches if
properly installed. Modified Bitumen, TPO, EPDM, and PVC roofs are usually easily patched.
