Question for the Experts: Do I Need to Wash My Roof?

Out of sight, out of mind.

The roof over our head is something we just assume is there – it is a rare homeowner who considers the condition of their roof unless they are concerned that something is going wrong. Still, between a “newly installed roof” and a “roof which needs replacing” is a lot of time, wear and tear and maintenance. We all understand that it is important to fix our roof when we discover roof damage or a roof leak. But a question we hear often at Kingdom Roofing is this – “Do I really need to wash my roof? ”

Is it Necessary to Wash My Roof?

One of the most compelling reasons to wash your roof is simply keeping up appearances. A dirty or moss covered roof can significantly detract from the curb appeal of your home – meaning a roof cleaning prior to selling your home is definitely recommended! Even if a dirty roof doesn’t worry you personally, in the Venice area we have many HOAs (homeowner associations) which do require residents to clean their roof on a regular basis, in order to maintain the standards of the community.

Asphalt shingle roofs are susceptible to mold and algae growth, and both of these conditions can greatly reduce the health and longevity of your roof. Therefore, if you have a roof made out of asphalt shingle and you notice the tell-tale dark spots on your roof, you may wish to consider gently washing your roof.

Clay tile and terra cotta roofs present less of a problem, as these materials are not conducive to mold or algae growth. While you may find small areas in shady parts of the roof, overall cleaning your tile roof is a matter of choice.

Gently Cleaning Your Roof

If you decide to clean your roof, you may wish to keep a few things in mind:

• You should never step out onto your roof unless absolutely necessary. You may actually do damage to the roofing materials if you do so. Use a ladder, a hose with a spray nozzle, or a power washer on a low level.
• Remember that asphalt shingle roofs are subject to deterioration through granular loss, so you want to be very gentle with any method of cleaning. Granular loss will shorten the lifespan of the shingle. If you see loose granules running into the gutter, stop cleaning and consult a roofing contractor as how to proceed.
• Most dirty roofs can be cleaned utilizing only water, but your local roofing contrctor may also have suggestions as to mild cleansing solutions which are acceptable and safe for your roof.

Roof maintenance is more than just waiting for a roof leak and fixing problems as they occur. By calling a roofing professional for an annual inspection; making sure gutters are clear and allowing water to flow; cleaning algae, and mold and debris off your roof on a regular basis – you can be assured that you are doing the most you can to ensure that your roof will last as long as possible.

So, you may ask – should I wash my roof? The best place to start is with a roof inspection.
