How To Attach A Pergola To A House With Gutters


A pergola is a beautiful addition to any home, providing a cozy outdoor space for relaxation and entertainment. If you have gutters installed on your house, you may be wondering how to effectively attach a pergola without damaging or obstructing them. In this article, we will guide you through the process of safely attaching a pergola to a house with gutters, so you can create a stunning outdoor oasis while maintaining the functionality of your gutters.

Step 1: Evaluate Your Gutter System

Before you can start attaching a pergola to your house, it’s important to assess the type and condition of your gutter system. Look for any signs of damage or weakness, such as loose or sagging gutters, as these issues should be addressed prior to installation. Make sure your gutters are securely fastened to the fascia board and can withstand the additional weight and stress that a pergola may exert.

Step 2: Choose the Right Mounting Option

When attaching a pergola to a house with gutters, you have a few different options for mounting. The most common methods include using a ledger board, mounting brackets, or by utilizing the existing structure of the house. Let’s explore each of these options in more detail:

Ledger Board:

A ledger board is a horizontal piece of lumber that is attached directly to the house. This method offers excellent stability and is recommended for attaching a pergola to a house with gutters. To install a ledger board, follow these steps:

1. Start by determining the desired height of your pergola and mark the corresponding level on the house.
2. Use a tape measure and level to ensure the marks are accurate and level.
3. Attach the ledger board to the house by driving lag screws or bolts through the board and into the wall studs. Make sure the screws or bolts are long enough to provide a secure attachment to the structure.
4. Space the screws or bolts approximately 16-24 inches apart along the length of the board for optimal support.
5. Once the ledger board is securely fastened to the house, you can proceed with attaching the pergola posts.

Mounting Brackets:

Using mounting brackets is another option for attaching a pergola to a house with gutters. This method involves attaching brackets directly to the house, allowing you to easily connect the pergola posts. Here’s how you can install the mounting brackets:

1. Determine the location of the pergola posts and mark them on the house accordingly.
2. Attach the mounting brackets to the house using screws or bolts, ensuring they are level and securely fastened.
3. Once the brackets are installed, you can connect the pergola posts to them using appropriate hardware and fasteners as recommended by the manufacturer.

Utilizing the Existing Structure:

If your house has an existing structure, such as a porch or overhang, you can use that as a support for your pergola instead of directly attaching it to the house with gutters. This method may require additional reinforcement and consultation with a professional to ensure the structural integrity and safety.

Step 3: Securely Attach the Pergola

With the mounting option chosen and implemented, it’s time to securely attach the pergola to the house. You should follow the specific instructions provided by the pergola manufacturer, as the process may vary depending on the design and materials used. However, here are some general guidelines to keep in mind:

– Use appropriate hardware and fasteners recommended by the manufacturer to ensure a secure attachment.
– Pre-drill holes for screws or bolts to prevent splitting of the wood.
– Double-check the levelness and alignment of the pergola to ensure a proper fit and appearance.
– Apply waterproof sealant or paint to the areas where the pergola attaches to the house to protect the wood and prevent water damage.
– Regularly inspect and maintain the attachment points to ensure they remain secure and in good condition.


Attaching a pergola to a house with gutters can be done safely and effectively by following the proper steps and utilizing the right mounting options. Prioritize the evaluation of your gutter system, choose a suitable mounting method, and securely attach the pergola while following manufacturer instructions. By doing so, you can create a beautiful outdoor space that enhances your home’s aesthetics without compromising the functionality of your gutters. Remember to consult professionals if you have any doubts or concerns throughout the process. Now, go ahead and enjoy your newly attached pergola!
