A timber frame shade structure should be inspected and lightly cleaned once or twice per year. Routine maintenance should include keeping leaves and debris off the structure, checking drainage around the posts, inspecting hardware and anchors, and watching for fading, finish wear, water traps, or storm related damage.
Finish maintenance depends on exposure. Areas with heavy sun exposure may benefit from light finish touch-ups every 1 to 2 years. A more complete maintenance coat is commonly needed every 2 to 5 years, depending on sun exposure, finish color, tree coverage, and local weather conditions.
Pergolas have exposed rafters and shade bars, so they typically receive more direct sun and weather exposure. Pavilions have a solid roof, which can help protect many overhead timber elements, but the roof system should also be checked for shingle or metal roof wear, flashing conditions where applicable, drainage, and storm related damage.
Surface checking is normal in exterior timber and is usually cosmetic, but deep damage, water traps, or finish failure should be addressed. A simple seasonal inspection is usually enough to catch small issues before they become expensive problems.
Maintenance is similar across timber frame pergolas and pavilions.
