This actually harms and damages the roof shingles with time, which may get cracked or pulled apart with the freezing Water or thawing. Furthermore, this may allow water to leak and rot the roof.

  3. The edge-seal of the moss to be removed by the knife’s edge
  4. There may be moss with bonded roots and slide the knife for cutting the roots. For best results, don’t lift the knife.
  5. A stick to be used to remove dump areas that can hold Water and damage.
  6. The roof surface should be swiped with a broom to remove the cut shingles and dirt.
  7. The work of black plastic cement starts from here as the damaged parts need to be repaired and sealed. Remember to smoothen and soothe it after applying.

Remove Moss From Roof with Vinegar

An affordable, readily available and an efficient product, vinegar can be used to kill the moss at the initial growth stages. It proves more effective in the first two weeks. Apple cider vinegar and white vinegar both of these can be used to treat the moss on the roof.

The main component of this is acetic acid and the commercial vinegars tend to have 25% higher concentration than the home-made vinegar which is just 5%. A few things may be required by you such as Water, spray bottle, putty knife along with items such as dish soap, plants and salt sprayer.

The Process:

  1. Like earlier, inspect the roof and identify the parts which are affected by moss
  2. Proper gloves and shoes should be worn to ensure a proper grip of the roof
  3. Using a sturdy ladder for climbing the roof should be ensured
  4. The household vinegar is sufficient for new moss and industrial strength proves more useful for older moss.
  5. It should be poured directly on the moss considering the old and the new
  6. Vinegar should be left for 5 to 10 minutes
  7. Next comes the surface scraping
  8. For not so delicate surfaces a putty knife can be used to remove moss
  9. The surface should be scrubbed
  10. Any leftover vinegar and moss should be washed off

The process can be repeated, in case more removal is required.

Changing PH Levels:

According to the studies, the minimising or increasing the levels of pH greatly help in restricting the moss habitat and helps in killing moss. A study conducted at Armentano et al. (The Bryologist Journal) the levels of pH such as 3.5, 6.4, 7.8 greatly affected the growth of moss.

If the environment base is made with a pH above 7 then it would be difficult for the moss to grow and survive. The suitable pH for the moss to exist is 5.0, 5.5, 6.0 or more. Changing environments will vanish their existence.

Many things are available in the home kitchens too, such as salt, soap, baking powder and baking soda. Eventually, you can make a good mixture of all of these with appropriate amount of Water and spread it on the moss to kill them. A pH level of 3.5 and the environment which is turned into acid kills moss in the best way. You can use a sprayer to directly for spreading the water and element mixture to abolish the moss atop your roof completely.

Proper care and monitoring are required as some of these may prove corrosive. There are some acids which have a pH level which is much below than 3.5 like juices of orange, apple, lemon, tomato and white distilled vinegar. If used in sufficient amounts these products prove to be quite effective. If the mixture is diluted perfectly then it prevents corrosion too.

Soft Washing:

The roof which is to be cleaned should be covered suitably before removing the moss. By making use of the hand tools you can remove the mess manually. By now, you will be able to remove the moss physically, and a soft wash to be done using a specialist equipment. This should be done after removing the moss and softly.

This is an effective way to kill the moss. Furthermore, whatever debris gets collected in the gutter should be removed for cleaning purposes. This is an absolutely safe and environment-friendly way that removes moss from the roof. This ensures that the moss is killed and the original condition of the roof is restored.

Blowing And Cleaning With Hands:

The simplest way to clean and clear the moss is blowing and cleaning. On a normal basis you can blow any sort of dirt, dust, leaves and even branches from the roof. This will prevent accumulation of any kind of moisture which may support moss growth. You can later dampen it with Water and get rid of it with the help of a nylon brush.

For preparing the mixture, use 75% of bleach along with 8 to 6 particles of dish washing soap. This can be filled in the pump sprayer, should be shaken well for ensuring a perfect mix.
