The coating has a high rate of failure in the winter.
This can lead to a condition known as “vacuum corrosion” which causes the roof to become discoloured.
This can cause you to notice the roof looks dull, worn and faded and cause your home to look dated.
It is also a potential cause of home damage.
To prevent this, you can buy a cheaper, lower quality shingle coating.
This coating is usually the best option if you are not planning on replacing the roof.
If your roof has gone dry, it may need to be replaced.
The cost of replacing a roof is usually around £50 to £100 and it is more expensive to buy a new roof.
