Bleach is a common cleaner for mold.  However, it is important to note that bleach merely discolours the mold, making it look as though it has vanished.  It does not reach the root of the problem and eventually the mold will return.  This is primarily because bleach has no anti-microbial properties.

The best types of products to use to remove mold from the roof or anywhere for that matter are biocides and anti-microbial cleaners.  There are green options available, which is advantageous because these products are not harmful and will not damage the landscape under the roof.  These cleaners will destroy the mold and any underlying slime that might remain.  It is best to speak to professionals to get the best possible product for your mold removal needs.

Some may use the opportunity to replace the roof tiles altogether.  This is an expensive option, but if the quality of the shingles are already depleting, it may be beneficial to have them replaced.  Alternatively, bringing in a professional to repair the problem is the optimal choice, because they will clean the mold and prevent it from recurring.  Professionals will complete the job effectively and minimize any further damage to the tiles or the roof.  However, be aware that this also can be quite expensive.  On the other hand, if you consider yourself handy, you can attempt to clean the roof and shingles yourself.  Spray the tiles with a mold killer and then rinse them with a hose.  Please refer to a guide for properly removing mold.

Prolong the life of your roof by being aware of any mold that could be developing.  The solution you choose of course is dependent on your own personal situation, but it is recommended to consult a roofing professional to make an educated decision.

Start by spraying the shingles with a mold spray.  If you have any plants or garden directly underneath the roof, it may be a good idea to cover them with a plastic tarp to prevent them from coming in contact with the chemical cleaner.  After spraying the solution on the shingles, let it sit for about 15 minutes.  Follow by rinsing with a water hose.  Do not use a pressure washer, as it will damage the shingles.  Allow the area to dry, and then spray once more to ensure that you caught it all.

Do not use a bleach/water mixture, as it is not a guarantee to kill all the mold below the surface.  In addition, bleach has a tendency to damage the shingles if has had a chance to sink in.  Although you should seek a professional opinion depending on the severity of the attack, smaller jobs can be easy to take care of the job yourself.

Once the mold has taken over, it is difficult and quite costly to remove it.  In some cases, the cost of replacing a home’s structure is greater than building a new home.  Black mold is difficult to spot, as the mold is not always visible to the naked eye.  Once it has begun to spread, it is nearly impossible to stop.  In addition to destroying the structure of your home, it also contaminates everything in it, causing families to leave with nothing but the clothes on their backs.

Professional roofing contractors are familiar with this despicable growth and know what to look for and how to prevent it.  In this case, the best defence is prevention.  It is wise to have a professional roofing company inspect your home on a regular basis.  Though it may seem like an unnecessary expense, the benefit of doing this far outweighs the cost of finding a new home or paying for the renovations needed to make your home safe.
