Being strategic about downspout locations prevents water damage to your pole barn foundation and landscaping. Moreover, connecting a tile system to your downspouts gives you complete control of where the water will go.
The elbows are pieces of bent metal that redirect the water flow from the troughs to the pipes that run vertically along your side walls.
The two types of gutter elbows are A-style and B-style. A-style elbows direct water flow forward or backward. B-style elbows move water to the left or right of the downspout.
5) Pipe Cleats
Pipe cleats are brackets that secure the downspouts to the side of your post-frame building. This metal strap wraps around the downspout and clips through various pole barn exteriors (e.g., brick or vinyl siding) with heavy-duty screws.
Hangers play a supporting role in keeping your gutters attached to the roofing system.
This modern component replaces the use of spikes and ferrules. When properly installed, hangers prevent the troughs from loosening or detaching, even in high winds or under heavy snow loads.
Gutter hangers have two parts: a metal bracket with an angled screw that fastens to the fascia board and a metal hanger that clips the trough into place from the front.
Why Should You Install a Gutter System?
Again, gutters stop water from pooling around your pole barn foundation. Without proper drainage control, runoff can cause serious damage and lead to the following types of post-frame building repairs:
First, it’s a good idea to plan ahead by drawing your gutter system on paper. Estimate the amount of building materials and accessories needed. Additionally, you can place the downspout locations clear of any doors and windows.
Then, you can lay out the entire gutter system and power tools alongside the pole barn, directly on the ground, or propped up on saw horses.
Step #2: Prepare the Gutters
Second, place the hangers along the trough length and attach the end caps with a crimping tool.Having a gradall basket readily available with the gutters prepared in front of you makes for a smooth pole barn renovation project.
Step #3: Install Gutters at the Corner of Your Post-Frame Building
Third, start the gutter installation at the corners of your pole barn where the downspouts will be. Create 3” gutter laps every 16’ to ensure the water drains over the lap rather than into it.
Apply lap sealant for a watertight seal where the two gutter sections meet. This specific adhesive helps maintain the structural integrity of the gutter system by directing water away from the post-frame building without seeping through the seams. Lap sealant is UV stabilized to prevent deterioration and discolorization.
Work your way from one corner to the center of your pole barn, then repeat the process on the other end.
Step #4: Secure Your Gutters to the Fascia Board
Next, fasten the gutters and hangers to the fascia board with screws. This straight board runs parallel to the roofline and affixes to the ends of the rafters or pole barn trusses. The primary purpose of a fascia board is to keep moisture from infiltrating your post-frame building.
Editor’s Note:You may run into rotted fascia boards when adding gutters to an existing pole barn. New lumber must be installed before moving forward with the installation process.
Step #5: Connect Gutters to Downspouts
Lastly, create an opening in the gutters to accommodate the downspouts. A common rule is to have one downspout per 40’ gutter span for proper drainage.
However, FBi Buildings calculates the number based on the pole barn size, gutter size, downspout size, and rainfall intensity. We use 3x4 rectangular downspouts for a 6” K-style gutter system because of the larger rainfall it can drain.
Insert the downspout outlet and coat it with sealant. Fit the top elbow over the outlet, facing towards the pole barn. Secure a second elbow to the side of the post-frame building. Measure and cut the downspout length.
Connect the downspout to the top elbows. Attach a bottom elbow and gutter extender (optional but preferred) to direct water from the pole barn. Omit this piece if the downspout is connecting to a tile system.
Wrap pipe cleats around the downspout and screw into the metal siding. You may need an extra set of hands to hold the downspout while fastening these straps into place. We recommend screws over nailsbecause of their clean aesthetic, stronger holding power, and long-lasting watertight seal.
Bonus Step: Overhang Considerations
If your post-frame building lacks overhangs, install a 1” x 3” x 8’ furring strip where this pole barn ventilation option would be. Add an eave guard over the furring strip. Fasten gutters through these building materials and into the fascia board. Repeat the same step-by-step process detailed above.
Do You Need Help Adding Gutters to Your Existing Pole Barn?
Some DIYers describe this hands-on experience as enjoyable and rewarding, especially if they generally understand post-frame construction. Meanwhile, others are surprised by how tricky and time-consuming installing rain gutters can be.
Maybe you’ve decided that DIY isn’t the best option for you. Sometimes, attaching a gutter system to an existing structure is a better fit for metal roofing professionals.
