Why is Moss on The Roof Bad?

In the roof cleaning industry, there is definitely one common conclusion and it is that Moss Mould and Lichen are not good for roofs. As the moss thickens and grows on a shingle roof it can raise the shingles up (much like a jack under a car). When the shingles get risen it allows water to go under the shingles causing the decking to rot and causing the roof to leak. The raised shingles also pose problems when heavy winds are present because they will catch the wind like a sail and this can cause shingles to be torn/blown off the roof. A moss buildup on the roof causes more debris to get trapped on the roof. This debris promotes water buildup which makes the roof at risk of much more rotting and leaking. Moss and Lichen can actually damage the shingle components leaving it to break down faster.You can read some tips on Lichen removal on roofs here.

"Hi Henry, Your product has quite frankly outdone anything I have previously used. Your email has prompted me to have another closer look on my roof just now and since I last applied the Moss and Lichen Slayer late May last year I can’t find any noticeable patches. That's the first time I have achieved that result in that time period. I still have another container to get through but it’s probably not enough to finish the roof again though. I should look at grabbing some more really. Regards"

Saved us time and money

"We are owners of a motel complex and we have used various products over the past 15 years. We discovered Spik and Span Moss and Mould killer about 5 years ago and we would not change to anything else.We got faster kill rates and slower regrowth.

It costs us nearly half what were paying on other brands."

Nothing has been far more superior than Spik and Span Moss Kill

"I have used Spik and Span Moss Kill on my south side of my house as it is so damp and the moisture is just creating a moss like substance. I don't know much about it really. I used a 5 Litre pack and it cleaned it up within a week. I have used other well advertised products and nothing has been far more superior than Spik Moss Kill. I would certainly recommend it to anyone. Cheers Spik and Span NZ"

Spik and Span is a beauty

"Spik and Span orange cleaner is a beauty. It cleans so well and a good test recently was the stinky tilt a hood filter that was full of oil and grease. Using Spik and Span at 10-1 with water, allowing it soak in and then hosing it off afterwards the oil and grease broke down easily and left the filter looking like brand new. It also left a fresh orange smell in the filter that has lasted for days now."

Moss & Mould Killer on my Pavers

"I used Spik and Span Moss and Mould Killer on my pavers. I am most impressed. 1 week after spraying it is already showing distinct signs of working. I have also sprayed moss in my lawn. Moss has gone a yellow colour and lawn is still green. Good bye to moss and mould forever. So pleased to have found this product."

"Just ordering some more Moss and lichen removal product and wished to tell how pleased I am with your product. I have tried nearly everything under the sun to get rid of the lichen on my driveway. We got rid of it within 4 months.We are now going to spray our roof and hope to get a similar result. Fingers crossed."

I used Spik and Spans Moss and Mould Killer last week

"I used Spik and Spans Moss and Mould Killer last week and sprayed it on everything from my paths to the deck and everything else in reach. Apart from the bits I missed the green gunk has gone, no rain either till tonight , just heavy frosts! I was told it may take a couple of weeks but it has gone in a few days. I am delighted to say the least and have ordered more! I also have used Spik and Span household concentrate cleaner. It cleaned everything it touched!! From the bathroom , to bench tops , my stainless jug, and rubbish bin etc. I am really impressed with Spik and Span's service that I received and would certainly recommend these products to everyone. Cheers Spik and Span."
