Snow load capacity ranges from 80 to 200 kg/m², depending on the pergola’s size and model. This means that, on average, a pergola roof can withstand a snow layer up to 10 cm thick. However, the weight of 10 cm of wet snow can reach as high as 500 to 600 kg/m², so the wetter the snow, the greater the load the pergola roof will be subjected to. Snow that has been there for some time begins to compact under its own weight and also becomes denser.

Pergolas are intended for outdoor use and are designed to withstand the elements—their structures are made of aluminum and coated with a powder coating.

To extend the life of your pergola’s finish, you can use specialized products, such as the RENSON Maintenance Set. The products in this maintenance kit will ensure that the colors remain vibrant for years to come and provide additional protection against acid rain, the salty coastal environment, and UV rays.

Most often, no—but every property and situation is unique, depending on the type of construction project and the specific characteristics of the lot — encumbrances, location, the presence of buffer zones, and other factors—so we always recommend consulting with your local municipality on these matters.

Of course, a pergola increases the value of the property, and its installation is often viewed as an investment.
