Will My Tile Roof Need Cleaning

Believe it or not, cleaning the tile roof is important. There are a variety of reasons for you to clean your tile roof. Just like many other areas of your home, maintenance of the roof tiles is important towards the longevity of the tiles. If you hire a roof cleaning contractor, make sure that there are reputable. Let’s take a look at the reasons why we need our tile roof cleaning.

  • Moss – if moss grows on the roof tiles, it will need to be removed. Moss will contribute to the softening of your roof tiles. This, in turn, will crack and split the roof tiles. It is also damaging to the aesthetics of your home.
  • Cracking – if the tiles crack and split, moisture will get into your wood decking and other parts of the roofing structure.
  • Roof pitches – the roof is typically positioned on a slope. This keeps excess water from pooling on the roof. Roof runoff is necessary to prevent algae, lichen, and moss from growing on the roof tiles.
  • Neglect – it is never a good idea to neglect your roof. Keep in mind that a storm can dump added debris, dirt, pine needles, and mud to your roof. If this occurs, clogs and water damage could occur.

What Are The Steps For Cleaning

  2. Always spray toward the gutters so that the runoff goes away from the home.
  3. If moss, lichen, algae, or other organisms have grown on the roof, add your roof cleaner chemical and allow it to soak in. Read the directions for diluting the chemical as needed.
  4. When it comes to rinsing, use very low pressure. Look towards 60 psi or lower. Homeowners should consider a garden hose. Also, rinse the gutters so that everything stays clean and clear.
  5. As soon as you are done cleaning the roof, make sure that you use a sealant to coat your roof tiles. This protects the roof tiles from sunlight, wind, rain, and other airborne debris. Also, the sealant will keep the color of your roof tiles looking good.

How Much Does It Cost
