That was just a preview of the main event. In this step-by-step process, we’ve answered all your how’s and why’s.
What are you waiting for? Let’s start the mission!
What’s Flashing? Why Use Flashing?
Flashing is a layer of water-resistant material. It acts as a barrier to drive moisture away from your home. It keeps your house from water clogging and rotting.
Certain parts of your home are at the most risk of rotting or water leaking. Roof intersection, door/window surrounding, between sidings-wall, and siding-paver are core flashing spots.
Whenever your house goes through some transition or redecoration, use flashing.
Placing pavers directly against the siding is basically preparation for water damage. Your sprinkler system and wet soil under concrete make the siding moist. So, even if the rotting doesn’t affect right away, it’s coming eventually.
Your geographic location also matters here. If you live in a dry area, consider yourself lucky. But, if your area gets a lot of rain or dew, you have more problems.
In case you have wood siding, get ready to welcome those carpenter ants. This infestation can lead to a colony of carpenter ants. So it’s best to get rid of these ants as soon as you can.
Better be safe than sorry, right?
Pick Your Flashing
There’s a variety of flashing to choose from. Copper, aluminum, plastic, vinyl flashing are all good for different purposes.
Choose the one that fits best for your needs. There are several things to consider while picking flashing:
- Geographic location
- Weather (temperature, humidity, rain frequency)
- A place to set flashing (roof, chimney, siding, etc)
- Flashing material
Contemplating each of them is important. For example, flashing between siding and brick walls needs to be durable. So, metal sheet flashing is a good option for that.
Water can easily collect against pavers. So, you need something that doesn’t react with water. Vinyl flashing is best for this case. It offers durability and low maintenance at the same time.
Now, there are various shapes of flashing as well. Nonetheless, L shape flashing is good for the top/bottom of the sidings.
How to Install Flashing Between Paver and Siding
Step 1: Grab Your Tools
Every hack requires a seasoned DIYer like you and a bunch of tools. So, gather all the tools beforehand. That way you don’t have to run here and there in the middle.
- Protective clothes
- Measuring Tape
- Silicone Adhesive
- Rubber Membrane
Tip: Keep your general toolbox within reach as well. You never know when a new necessity jumps in. If you don’t have one, keep a screwdriver in hand. You might need to unscrew a siding to set the flashing well.
Step 2: Do Your Measurements Right
Now, before you get to the flashing, you need to get them ready first.
Got the perfect design and plan for your paver patio? Or is it a deck? In any way, measure the paver size according to that with your measurement tape. Note those numbers down.
Finally, get your jigsaw and goggles, if you haven’t already. Now, cut down the flashing according to that measurement. Make sure to follow the numbers to the point.
Because one tiny gap is all you need for a water leak. Your wood siding won’t stand against water clogging. Not to mention the horrors of finding rotten plywood!
Step 3: Install Flashing
Finally, it’s time for the installation. But before adding flashing, cover the sheathing with a rubber membrane. It adds another layer of protection.
Now what you need is a barrier between your siding and pavers. So that, water or any other fluids doesn’t leak and damage your sidings. Hence the L-shaped flashing.
Cautiously, insert the L-shaped flashing under the down most siding. Leave approximately ¼ inches of air space for wood siding. Even if the sidings aren’t installed yet, follow the ¼ inches rule.
Moist can spread with the minimum graze of water. So, cover ½ inches higher than the paver’s height to be cautious. Set them in place with screws.
Step 4: Seal the Deal
The sealant will cover all the edges of the flashing. So, picking the right one is important. Silicone adhesive is a great option for this case. You can also use silicone for bathroom tile, in favor of great finishing.
Here are some of our favorite sealant for your convenience:
Pick the one to your liking and get to work.
Now to make sure they stay that way, leave nothing to chance. Cover all the edges with silicone adhesive. Apply the adhesive on the ¼ inches of the outer edge.
Usually, silicone adhesive takes approximately 24 hours to set perfectly. So, let it rest for a day. Then they’ll be ready to take on any moisture or fluid.
When they are dried and set, you’re ready to add that paver patio.
Yes! You are done with the flashing! Now, go and add those pavers on without any worry.
Flashing is good protection against moisture. So, you may consider putting flashing for brick walls and siding as well.
Question: What materials are used for flashing?

Question: Can you glue pavers together?
Answer: you can glue pavers together with a good Polyurethane Construction Adhesive. Cut the tube of adhesive in desired bead size and apply it in a zigzag pattern. Press them together firmly and wait for them to set.
Question: Where do you need flashing?
Answer: Flashing is necessary for areas to cease water leaks and thus water damage. So, chimney, Sidings, Joints, Beam Pocket, Seals, Caps, and Rowlocks are some of the places that need flashing most.
That’s all that you need to know about flashing between pavers and siding. Now that we have answered all your questions, you are good to go.
Just follow this process as much as you can. Soon you’ll have a wonderful paver patio with proper water protection.
