How To: Remove Roof Moss – Safely

Moss on the roof isn’t just unsightly, it can damage your tiles and cause damp. Before you make the most of even more time at home by getting up onto your roof to get rid of that moss, it is important that you understand how to do the job properly. A gung-ho attitude could cause more harm than good. We take a look at some common questions about moss on rooves – asked by customers and answered by reliable local traders.

Q1: Is it important to remove moss?

A: Whether you are offended by the appearance of moss or not, the argument to remove it extends far beyond the cosmetic. Moss acts as a sponge, soaking up moisture, rain, hail and snow, and holding it in place on your roof. Eventually, this moisture will leak through and could lead to structural damage. So, to put it simply, if you have significant moss coverage on your roof, get rid of it asap.

Q2: Can I just use the pressure washer?

A: No! Yes, a pressure washer will obliterate your moss, but it will also damage your roof and has potential to cause far greater long-term damage than the moss itself. A pressure washer is just too powerful; it will strip away surface granules and, if you have even the tiniest leak, could cause a leak or flood in your home.

Q3: So, what is the best way to remove moss?

A: As always, if in doubt, contact a professional tradesperson for advice. Clearing the moss from your roof isn’t just about removing the moss, it is about safely accessing your roof without causing further damage to people or possessions. If you can access the moss from a stable set of ladders or a flat roof, then you can remove moss fairly easily and cheaply using a stiff broom and a trowel. Don’t scrub too hard; you don’t want to damage the roof. Use the trowel to loosen stubborn moss, and brush it away with the broom.

Q4: Do moss removal chemicals work?

If you have significant moss coverage, chemical treatment can be a good solution. Although more expensive, chemical treatment kills small moss spores that you won’t necessarily see when cleaning with a trowel and brush, as well as any moss that has got into more hard-to-reach areas. Using chemicals isn’t a quick fix, however. Before you use moss removal chemicals you need to remove most of the moss before covering up any plants or furniture that could be sprayed accidentally during the process. Be aware that moss chemicals won’t just kill or damage your moss – so be extra cautious if you do decide to use it.

If you have moss coverage on your roof and you are not sure about accessing your roof or removing the moss yourself, get in touch with a local handyman or roofing specialist for a quote. If you secure a handyman, you can get him to check your gutters while he is there!

Q5: Can you prevent moss?

A: Copper or zinc strips can be used to prevent moss growth - follow Trust A Trader on Facebook or Twitter to find out more.
