The health of your tile roof is essential to the health of your home. If you allow leaves and other debris to accumulate on your roof, that material could turn into compost, which can provide a fertile soil for weeds to grow. In addition, roofs that are in shady or moist areas can grow moss, another type of weed. In order to prevent expensive damage to your tile roof, these weeds must be removed thoroughly and as quickly as possible.
1 Remove as much debris from your tile roof as possible, using a blower, a pressure washer or just a simple push broom depending on how much has accumulated.
2 Select a method for killing the weeds. Different weeds will respond to different treatments. For example, you can spray an appropriate weed killer, or you can suffocate the weeds by covering them with cardboard or newspaper. What you choose will depend upon how much time you have and whether you are adverse to using chemical solutions.
3 Kill the weeds according to your chosen method. Killing weeds before you remove them will prevent further damage to your tile roof if the weeds have taken root.
4 Dislodge the weeds. Turn a pressure washer on "High." Spray away the dead weeds or moss and clear off any remaining debris.
5 Prevent reinfestation. For moss, install a zinc strip along the edge of the roof. For weeds, spray a weed killer or homemade solution to ensure that the roots will not reseed.
6 Repair any damage to your roof. If weeds have caused holes or leaks to form in your tile roof, repair the area to ensure that you do not face more costly repairs inside your home.
