Regular Roof Cleaning By Professionals Can Extend the Life of Your Roof
These growths attract moisture and will cause damage to the roof if left uncleaned for a long time. They can also cause the shingles to separate and this will lead to the roof leaking, damage to the ceiling and other problems for the structure of your roof.
Regular cleaning of a roof, as part of roof maintenance, will preserve the life of its roof coverings. It is a job that requires skill that must have attention from the professionals. But that does not mean that you do not use your garden hose occasionally and spray some water on your roof to clear it of any dirt and debris on it.
Proper Roof Washing
If the roof is old it is best cleaned without using power washers. This process starts with applying detergent and surfactants to the surface of the roof. These chemicals will make their way into underside of the roof as well, around flashing and other roof structures and should dissolve the grit ,grime, and dust that has accumulated on the roof.
These detergents should be given some time to work their magic, before they are rinsed. The pressure used in soft washing must be low, and slightly more than what you would get with a garden hose that has a spray nozzle.
Your roofing contractor will know what is the sort of pressure that can clean the roof without damaging it, and you must never interfere with his selection of pressure, as some people feel that higher pressure leads to better cleaning. Concentrate instead on the final result and how clean your roof looks after it has been cleaned. You have every right to inspect the roof, and point out any lacunae in the cleaning if you do spot it.
Your roof will have a longer and better service life, if you do not wait for the telltale signs of dark spots, algae, mold or dirt to show before you clean it or arrange for an agency to undertake this important job. A roof that is washed with regular consistency will remove any leaves, twigs seeds and other dirt and debris that often facilitate growth of mold and algae. Couple it with the inspection and maintenance that caring homeowners will always schedule at intervals of once or twice a year.
You can also take up such cleaning after severe storms that have led to an accumulation of tree leaves, branches, and other dirt that the storms will bring on to roofs. This cleaning can also clear your gutters and down spouts and ensure that they are fully functional, as they will have to drain away the water that is a result of the cleaning operation.
Take care also to clear any gutter guards you may have installed in your gutters to prevent them from being filled with leaves from the trees in your yard or areas around your property. Roof cleaning can also help you avoid the formation of ice dams that can form on the edges of roofs that have not been cleaned. As you know, ice dams can cause water to seep in under eaves and shingles and damage the walls of your house.
It is important that if you are having to need the roof repaired for any damage to it, this may also be a good time to go in for roof cleaning, prior to carrying out the repairs. This cleaning will make any other defects show up visually and then ensure that your roof repairs are extensive and cover all the portions that have been damaged.
It is important that roof cleaning work is allotted to a good roof cleaning contractor, as doing it yourself is risky. Make sure that the contractor has adequate insurance, proper equipment and well trained professionals who will always follow safety regulations.
Ask them to explain the methods that they will use to clean your roof, so that you can be sure that you are comfortable with their work. Ensure that this method is acceptable to your insurance company.
