Year after year, the roof tiles of your house are exposed to the wrath of nature and, if they are not paid proper attention, they begin to look deteriorated. Mold, moss, and tree sap begin to accumulate on the roof tiles, making the roof look old and ugly. Most of us pay close attention to cleaning the windows, doors, and floors in our home, but we tend to overlook the ceiling as it is out of sight and therefore out of mind.
3 reasons why you should think about cleaning your shingles
Cleaning your roof tiles offers three main benefits:
1. Increase the aesthetic value:
Stains, moss, and mold build up over time and damage the overall appearance of your roof and the entire home. Regular cleaning keeps such destructive elements at bay.
2. Early detection of damage:
When you start cleaning the roof, you can spot some of the minor damage that has been caused to the shingle structure due to age, weather, or other factors.
3. Extends the life of your roof:
After cleaning, you can prime and paint the shingles, which can help prevent further build-up of moss and dirt and therefore increase the longevity of the shingles.
Chemicals used to clean tiles:
Shingles are often cleaned with chemicals that are spread over them and left on the shingles for a short period of time, then washed with a pressure washer. Good roof cleaning companies recommend and use sodium hydroxide-based products. These products are safe, ecological and very effective as cleaning and degreasing agents.
A cheaper solution is to use a solution of chlorine bleach and water. Another effective cleaning combination is a mixture of detergent, bleach, and trisodium phosphate in warm water. Some roof cleaning companies completely avoid the use of bleaching agents and only use hot water or steam to clean the roof tiles.
Tile roof cleaning methods:
Cleaning shingles requires the skill and experience of a professional. A professional roof cleaning service will clean your tile roof in the following steps:
1. Initial pressure wash:
The first step is to pressure wash the shingles to remove loose dirt, debris, including insects, leaves, twigs, etc. Pressure is applied from the ridge descending into the gutter. Then the ceiling is allowed to dry completely.
Pressure wash again, but this time using less water pressure than the initial wash and using a chemical mixture that is sprayed all over the dry tiles. This process allows the chemical to enter the pores of the tiles. It is recommended to let the chemicals stay on the tiles for a while, to allow additional residue on the tiles to loosen.
