Depending on the design of the pergola, it can offer some protection from light rain. However, pergolas are not typically built to be rainproof. They are an open, airy structure with a lattice style roof designed to let light into the structure and for hot air to escape through the openings in the roof. Therefore, they don’t block much rain. If you want a solid, rainproof structure, we can incorporate a roof covering with your custom pergola!
