Roof openings are susceptible to leaking, and chimneys are no exception. To reduce the odds of leaking, flashing must be installed all the way around a chimney and then be properly sealed to keep out water. Sealing flashing in the right way will preserve the life of the roof, and make it less likely a Fort Worth roofing contractor will need to perform repairs to correct damage.

Chimneys should ideally have a strip of metal that is 6 to 8 inches around the transition joint. This flashing should then be covered with a layer of shingles that are attached directly to the underlayment of the roof. Before sealing takes place, the flashing and shingles should be inspected for signs of damage so that repairs can be made if needed.

Once a homeowner has determined that his or her flashing is in good condition, any holes that are present should then be filled with roof caulking. Roof caulking is applied in the same manner as window or plumbing caulking. It should be left to dry before adding sealant.

Once the caulking is dry, an elastomeric sealer can then be applied to the roof. This sealer comes in black, which is a good choice for dark-colored roofs, or clear, which may be used on lighter shingles.

A paint brush or roller can be used to apply the sealer and ensure it completely covers all exposed edges of flashing.

More than one coat of flashing may be needed. Individuals should read the manufacturer's specifications to determine whether or not this is the case. If more than one coat is necessary, plenty of time should be allotted for drying between them. Most roofing sealants require at least 24 hours between coats.

Roof sealant should be applied whenever temperatures are above freezing and rain is not expected for at least 24 hours. However, if the roof is already leaking, there is no need to wait until warmer or drier weather. Sealer can still be applied, even when it is cold outside or the roof is already damp from precipitation. In these instances, a heavier coat of sealer or more than one coat of the product may be needed to achieve the same results.

Applying sealant to chimney flashing is an easy task that most homeowners can perform themselves. It is also a very essential task that will ensure the flashing around a chimney provides adequate protection for years to come.
