Attaching a Pergola to an Existing House

Attached pergolas can be beautiful additions to any home. Attaching a pergola is a great way to make use of a home’s existing strength. This is a popular choice for home owners that are building pergolas. An attached pergola makes a nice transition from the inside of the house to the outdoors. Many people consider an attached pergola to add square footage to the living space of a home.

 

Types of Attachments

Pergolas can be attached in various ways. Many builders will attach a pergola to an outer wall or roof structure. Pergolas that are attached to a wall will usually require a large support beam and bolts. For attaching a pergola to the house fascia, a beam will be utilized as well as rafter brackets and bolts. Finally attaching a pergola to roof support stirrups involves brackets, bolts and a rubber barrier for waterproofing. Attaching the pergola to the house fascia is often the most common way to build a pergola.

The following instructions are for attaching a pergola to the house fascia. Accurate measurements are imperative when getting ready to construct an attached pergola. Marking the measured areas using stakes and strings is the next step. When everything is properly marked out, construction can begin. A strong beam will need to be installed directly onto the fascia, under the gutter.

Initial Setup for Construction

If the house exterior is wood or timber, the beam can be nailed directly into the wall. It is important to take great care in making sure the beam is level. Galvanized brackets should be the next installation. They can be attached directly to the rafters of the house. Bolts will be needed for securing the beam and brackets. These bolts should be placed in one meter intervals. This step is important for load-bearing integrity. Some pergola plans will include instructions on how far apart to bolt these brackets in.

Special care must be taken when attaching pergolas to metal fascias. Properly securing the support beam to the house rafters is the most important aspect of building this type of attached pergola. This job is best completed with the help of assistants. It may be necessary to have helpers to hold the beam in place until it is sufficiently bolted into the house’s rafters.

In addition to the above mentioned methods, there are various other ways to build attached pergolas. Some smaller pergolas can be built without the use of a support beam. For this type of construction, special brackets must be purchased. Rafter brackets can be screwed into the house rafters with the use of special bolts. Some attachments are done with timber beams being placed behind the outer wall of the house. These methods are not always advisable, especially for large pergolas.

Construction and Installation

Now that the support beam is in place, construction can begin. Beams and posts can be setup. Great care should be taken to make sure the construction of the pergola has correct angles. Everything should be square and properly braced. Sometimes, one side of a pergola must be cut in order to attain proper attachment. The house gutter should be taken into account when deciding where to cut the pergola. Cutting the pergola may not be necessary if it is being attached directly to an outer wall beam. Builders should take care in checking schematics. Sometimes cutting off the end of a pergola can be structurally detrimental to the construction process.

Attaching the pergola to the house fascia completes the basic construction. Although, the pergola may be far from being finished, it is now structurally sound. Finishing a pergola can depend upon the budget, and type of structure one wishes to complete. Pergolas that are attached without the use of a support beam should not be overloaded. Design should be limited to the safety of the structure. Referring to instructions is always crucial in the construction of attached pergolas.
