Just like any home improvement project, using a reputable service company in the field of solar systems is very important. For most homes where the solar panel is used, if the installation of solar panels is done by a reputable company that is professional and authorized to install it and also the roof of the house is in good condition, as a result, these houses will never be damaged. They are not their roofs, if the roofs of these houses were damaged, then most likely the roofs of these houses had problems from the beginning.
How to install solar panels on the roof?
Concern for damaging the roof when installing a solar panel is very unreasonable. Placing a solar panel on your retaining base on the roof of your home is one of the parts that will change the structure of your home, and if this is done by an unreliable company in the field of solar systems and incorrectly connected, your roof will be exposed. Danger.
One of the biggest concerns for homeowners when installing solar systems is the holes needed in the roof to secure the solar panels and secure them in place. These holes are for screw installation. And there are nuts with which the base of the solar panel is secured, and it is designed to withstand very bad weather. These holes and bolts are essential for almost any solar panel installation, and their size and depth are based on the material from which the roof is made. (Such as: asphalt, wood, etc.) and is different in each case.
To prevent water leakage into the house by a hole made in the roof of the house, several safety measures are taken by the installers of the solar panel to ensure that the structure of the roof of your house remains compatible and without any damage and no facial leaks. We do not accept that we will give a brief description of it:
To prevent water from passing through the hole, the bolts are surrounded by sealants, which are a metal or plastic shield that attaches under the tiles on the roof. These sealants are then coated with bitumen or similar materials. Finally, the holes in which the bolts and nuts are covered are covered with bitumen and protect the water from penetrating into the roof.

If you have a flat roof, you do not need to install a hole to install the solar panel. Because the bases used in the installation of this method are heavy enough to ensure that the solar panels on the roof are fixed and secure. Another way is to move your solar system to a place other than your roof, such as a yard or yard around your home, and you can make the most of this space and generate electricity from solar energy.
Aside from the problem of holes in the roof of the house, another common concern of homeowners who have used a solar panel is the added weight caused by installing a solar panel. In almost all cases, the added weight caused by installing solar panels does not pose a problem for the structure of the house, the roof of the house is usually designed to withstand much more weight than 20 to 30 solar panels and are durable.

If you live in a snowy climate, you don't need to worry about the weight of the snow collected on the solar panel because the solar panels are usually angled and the snow slides downwards. They do not accumulate on solar panels.
