Things to Keep in Mind While Building Your Own Sunroom

If you are not building the sunroom in your existing porch and you are planning to extend it then there are a few things that you need to consider before you proceed.

  • The first thing that you need to do is consult the local authority body, and check if it is permittable for you to extend. If you are not doing this in the beginning there could be serious trouble later which can lead to fine, road blockage issue and you can also be ordered to demolish the extended part of the sunroom.
  • If you are planning to build the sunroom on the side where you have a neighbor, make sure you consult them and let them know about your plans and make sure no issue arises later, especially regarding plot sharing.
  • The third thing that you should keep in mind is to choose the right sunroom kit. Sunroom kits are in great demand especially because they give you so much control over how you want your sunroom to be built and save a lot of the labor charges. Owing to its popularity, there are many types of sunroom kits that are available in the market but that does not mean that all of them are perfect for you. Materials like PVC and glass might look great, but they will not provide you with a durable and sturdy solution and any strong storm can destroy it. Make sure you choose something more reliable and stronger like aluminum and wood.
  • Your sunroom will also need some extra electrical outlets for basic electrical appliances like bulbs and fans. Consult a local electrician for planning the electrical outlets and make sure you calculate the cost of adding these to your overall cost. 

4 Ways to Build A Sunroom

4 Ways to Build A Sunroom

Even when selecting the right place to build your sunroom, there are a handful of options that you can choose from.

1. Building the Sunroom on An Existing Porch

The most economical option is to build your sunroom on an existing porch. The reason behind this is that you already have an existing roof and a base floor, all that you need to do is put up the frames on the side, add the windows and new flooring and jazz it up a little.

2. Building A Sunroom on Your Deck

If you do not want to build the sunroom on the porch or let’s say you do not have a porch then another great alternative is to build it on your deck. Although there might not be a roof over your head the base floor certainly makes it an economical choice. Just make sure you consult a local builder and get your deck checked to ensure it can bear the weight of a sunroom.

3. Building the Sunroom on Your Patio

Quite like building your sunroom on the deck, the patio just has a different foundation. In case you find out that your deck is not strong enough to bear the weight of a sunroom then your patio too can be a great option.

4. Building A Sunroom from Scratch

If none of the above options suit your need then the last and the best option that you have is to build the sunroom from scratch. Design a plan according to your requirements, select a suitable location and choose the window and flooring style as per your requirements.

So now we will discuss the steps that are involved in building the sunroom. Although there are several options in hand and the process will differ slightly based on which area you choose for the construction (porch, patio, deck, or an empty plot), we will be explaining the basic and general steps that are involved in the construction.

1. Prepare the Area Mark the Boundaries

The first step of building a sunroom is to clear the area, demolish and remove existing structures if any, and mark the boundaries and the layout of the room. The markings will help you determine the dimensions and keep each side in proportion.

2. Lay Down the Post Holders and The Support Beam

Here comes the foundation of your sunroom. At first, you will need to secure the post holder on the ground to provide support for the beams. Then you will need to place the beams on the post holder horizontally.

Make sure that all the beams are of equal dimensions and are not just at par with each other but also your house. Apart from their dimensions, you all need to adjust their heights on the support holder to make sure that the flooring is comes out even.

3. Lay Down the Flooring

The next step is to prepare the floor. You will need two sets of lumber for that whose dimension will depend on the existing dimension of your house. You will need to drive one set from the supporting beam and connect it to the framework of your existing house’s basement. Then place the second set of lumbar and cut it in a way that it fits the previous set within it. It will look something like this-

This crisscross framework will provide the support that your sunroom floor will need to bear the weight.

4. Attaching Metal Screen

This is a very important part that you just cannot afford to ignore. You will need to attach metal screens in the floor framework to prevent mice from entering the insulation space between the logs. The holes should be small enough to prevent mice from entering and make sure you do not put vapor barriers. This will trap the excess moisture and make the wood rot.

5. Lay Down the Floor Insulation

The next step is to lay down the floor insulation so that it is protected from mice and moisture.

6. Next Comes the Vapor Barrier

Now comes the vapor barrier. This should be only placed on top of the insulation layer and it helps protect the wood from excess moisture.

7.Lay Down the Sub-Floor

The next step on the floor is to lay down the sub-floor. You can go for a plywood subfloor but make sure you secure it with screws on all the sides properly to avoid squeaky floors.

8. Place the Walls

The next step that you must follow is to place the walls. For this, you will need to secure the individual plywood on the base. Start from the corners and secure them tightly with the screws to ensure durability and then fill in the gaps with equally spaced studs.

Make sure that when you are fixing the plywood for the walls, you have already planned out the space for the windows and leave adequate space accordingly. Once the framework of the walls has been built, place the sheeting on the outside wall, and remember to place a foam gasket between the brick of your house and the plywood of the sunroom that is touching the house. Then you need to drive in bolts through that plywood to fix it to the existing house. Make sure you seal the remaining gap with an insulation foam spray.

9. Placing the Ridge

In the next stage, you will have to place the ridge. The ridge will form the basic framework of the roof that supports the entire roof framework. Make sure you place the ridge on one of the supporting beams. The reason behind this is if you place the ridge on any other place apart from the supporting beams then the pressure will be too much for the supporting framework to bear.

Hence, to ensure a strong built, place the ridge directly on top of a supporting that will be able to balance the weight of the ridge. Make sure you calculate the slope of the roof before placing the ridge. The height of the ridge also plays an important role in the resultant slope of the roof.

10. Placing the Rafters and The Hangers

In this step, once the ridge has been placing, place the rafters but before you do that, make sure that you have secured the hangers. The hangers are a very important part of the construction of your roof because it is these wooden structures that will support the weight of the rafters.

You will see that once you are done with placing the rafters, the extended part also known as fascia will be hanging out. You can cut off these extra parts later. In case you have any doubts regarding the names of the different parts of a roof framework, refer to the diagram below.

11. Lay Down the Roof Sheeting and Shingles

Now you will have to put on the roof sheeting. Also, you will have to secure the sheeting, you will have to place clips between each rafter. You are also required to put “ice and water” rolls along every edge. Them, you will need to attach drip mold along every edge. Once you are done with the roof sheeting, attach the shingles or whichever kind of roofing you are using.

12. Prepare the Wall

In the next step, if you are planning to keep a wooden wall then you will need to lay down plywood again the wall and then fox it on both ends with the help of screws and you are planning to build a brick wall. Lay down the bricks against one another in a stack and put cement between the bricks as well as between the bricks and the wall to secure the frame of bricks.

13. Place the Windows and The Doors

Now that the wall is all ready, you will have to place the windows and doors in the framework. It will be easier to order a door or window from an expert or you can build one yourself following easy tutorials. Once the doors and windows are ready, place and screw them properly in the space that you have created for them.

14. Paint the Walls and Lay Down the Floor

Your gorgeous sunroom is almost ready. All that you need to do is paint the walls and lay down the flooring. Choose the flooring of your choice, be it wooden or flooring or tiles, and then once paint it up according to your choice.

15. Jazz It Up A Little and You Are Done

Your sunroom is ready! All that you need to do now is get your favorite lights, add a coffee table and a few comfy chairs or a couch, and maybe a bookshelf. Decorate it and jazz it up and you are set!
