Exterior Finishes: More Than Aesthetic

Similar to the roof, the exterior finish of a home is another protective barrier between the harsh elements of nature and the home’s vulnerable interior. While the home’s exterior finish may seem to have only an aesthetic purpose, it’s still a crucial aspect of any building. However, like other components of a home, many issues can pop up that may require prompt repair. Understanding what to look out for, when a solution is required, and what solution is needed is helpful in properly maintaining a home.

When it comes to a wooden exterior finish, one thing that can be observed is bowing. Due to the nature of wood, minimal bowing is common and doesn’t require repair. Additionally, the installation method of the siding can create bulges. If the siding was fastened using studs, changing temperature and humidity can cause bulges. However, performance guidelines state that any siding that bows in excess of ½ inch in 32 inches is excessive. If excessive, the wood will need to be replaced. 

Another issue that might be seen is siding boards appearing warped/cupped. If the boards are warped more than 3/16 of an inch in 5 ½ inches, it is deemed excessive by performance guidelines. Similar to bowing, wood is easily warped due to factors such as temperature and humidity, so minimal warp should be expected and doesn’t require repair. Since this is a common occurrence, it’s important to know the tolerance to only make repairs when necessary. Along with appearing warped, siding boards can split. Splits wider than ⅛ inch and longer than 1 inch are deemed excessive by guidelines and must be fixed.

In some cases, nail stains may be observed on siding / ceiling boards. If the stains exceed ½ inch from the nail and are visible from a distance of more than 20 feet, they are considered excessive and will need to be removed. Stains can happen due to oxidation of the nails or the leaching of extractives from the wood. Using different types of nails can help but doesn’t necessarily prevent nail stains.

A home’s exterior is more than just an aesthetic; it’s another line of defense between the weather and the home’s interior. As such, it’s important that this barrier stays in its best shape.
