There are several ways to attach a pergola to your house, but one of the most secure methods is to attach it to the gutters. This will ensure that the pergola is firmly attached to the house and will not move or shift over time. It is important to note that attaching a pergola to gutters is a bit more difficult than attaching it to other parts of the house, so it is important to follow the instructions carefully.

What You’ll Need

-1/4 inch drill bit
-3/8 inch drill bit
-1 inch hole saw
-Gutter screws
-1 1/2 inch wood screws
-Cordless impact driver (optional)
-Cordless drill (optional)
-Socket wrench (optional)
-Tape measure
-Pencil or marker
If you’re planning to attach your pergola to a house with gutters, you’ll need to take a few extra steps to make sure everything is properly secured. In addition to the ladder and drill, you’ll need a 1/4 inch drill bit, 3/8 inch drill bit, 1 inch hole saw, gutter screws, and 1 1/2 inch wood screws. If you have an impact driver and cordless drill, you can use those as well. You’ll also need a socket wrench if you’re using an impact driver. Finally, you’ll need a tape measure and pencil or marker to mark the locations of the screw holes.

Step One: Preparing the Area

If you are planning on attaching a pergola to your house, you will need to take a few precautionary measures to ensure that the structure is securely attached. The first thing you will need to do is to make sure that the area where you will be attaching the pergola is clear of any obstacles. This means that you will need to remove any gutters, downspouts, or other objects that could get in the way of the pergola’s attachment.

Once the area is clear, you will need to measure the distance between the house and the proposed location of the pergola. This measurement will be used to determine the size and placement of the footings for the pergola. Once the footings are in place, you can begin attaching the pergola to your house.

Step Two: Installing the Brackets

Now that you’ve got your pergola posts in place, it’s time to install the brackets that will support your beams. The type of bracket you use will depend on the type of gutters you have.

If you have standard open gutters, you can use L-brackets or T-brackets. For half-round gutters, you’ll need J-brackets.

To install the brackets, start by measuring and marking where you want them to go. Then, using a drill and screws that are appropriate for the material of your house (usually 3” or 4” long), screw the brackets into place.

Be sure to countersink the screws so that they sit flush with the bracket. This will ensure that your beams sit level and don’t wobble.

Step Three: Assembling the Pergola

Now that you have all of your materials gathered, it’s time to start assembling your pergola.

1.Start by attaching the two outer rafters to the ends of the crossbeam, using galvanized wood screws.

2.Then, attach the two inner rafters to the crossbeam, again using galvanized wood screws.

3.Next, attach the four corner braces to the ends of each rafter, using galvanized wood screws.

4.Finally, attach the top beam to the apex of the pergola, using galvanized wood screws.

Step Four: Attaching the Pergola to the House

If you are attaching your pergola to a house with gutters, you will need to take special care to avoid damaging the gutters. The easiest way to do this is to use lag bolts instead of nails or screws.

First, drill pilot holes through the support beam of the pergola and into the house. Be careful not to drill into the gutter itself! Then, insert lag bolts into the holes and tighten them until the pergola is securely attached.

Finally, check that the pergola is level and plumb before adding any cross beams or rafters. Once everything is in place, you can enjoy your new outdoor space!


In conclusion, attaching a pergola to your house with gutters is a great way to add some extra protection from the elements while also providing a beautiful addition to your home. By following the steps outlined in this article, you can easily and securely attach a pergola to your home in no time.
