roof treatment north shore auckland


The ROOF TREATMENT, North Shore, Auckland is undertaken by your local, #1 HWNS business. If your roof is covered in moss then having it cleaned actually makes sense. When it comes to roofs like any part of your home, they have a habit of getting dirty. Moss, algae and lichen are a common cause of these dirty and unsightly roofs.

Moss, algae and fungi normally begin their life cycle as airborne spores that settles on roofs, the spores on the northern exposure of the roof stand a better chance of survival because that portion of the roof is the last part to dry after a rain or morning dew. This raises the humidity on the surface of the tile, thus creating a perfect feeding and breeding ground.

Roof Cleaning and Roof Moss Removal Services Offered:

Roof Clean and Biocide Treatment

Once the roof has been properly cleaned, your roof will be treated with our “Moss Acrylic Roof Sealer” Microbiological Biocide which will impregnate and stop germination on a roof. It soaks into the roof tiles and remains active for approximately 2 to 3 years.

Many house washing companies will tell clients requiring moss, mould and lichen treatments on their roofs, they will need a second coating in a years time but at NSHW, the superior treatment we use will not only bring your roof clean but will keep your roof clean for up to 3 years, saving you the expense of the unnecessary 12 month second coating that inferior products used by many competitors require.

Wish all tradespeople were this good!

If you’ve ever tried to call or get a quote online, especially pre-Xmas, most tradespeople take forever to get back to you, if ever at all! The team from House Washing North Shore were able to respond and quote on the same day for a roof treatment and gutter clean, and was able to squeeze in a slot pre-Xmas which was greatly appreciated. On the day of the job, they SMS to confirm when they are coming ETA and again a few mins away – and turned up when they said they would! Job was completed efficiently and at a great price – I highly recommend House Washing North Shore and would use them again.

Great service and result

Needed an urgent chemical wash done on a commercial refurbishment and the boys shuffled a couple things to make it happen. Paul and Tony made it happen hassle free both admin wise and on site, and had the truck there in 2 days. I’m a new client and they will definitely be on the call for any future jobs. Thanks again lads.

THANKS SAM – pleasure is always ours in all new B2B relationships, as discussed in our first conversation. We look forward to helping you again in the very near future. Remember in JAN we launch our 5th van on the road too. Wishing you and your team a very enjoyable festive season!!
