Always match your shed roof to the house's pitch and overhang. Nearly flat shed roofs exist. Flat roofs are prone to leaking. Shed roofs slope away from the house in a single plane. If you're attaching the roof to a house wall, use a ledger board with flashing, rafter ties, or engineered trusses. On the opposite side of the porch roof, a header beam will be installed on 6x6 posts. Posts should be less than 8' apart and on frost footings. Hurricane ties attach rafters to the header beam.
You will need to remove the shingles and the sheathing in order to expose the framing of the roof if you are going to connect the shed roof to an existing roof that is already on the house. You will need to replace the roofing as well as the flashing, and then you will need to attach the porch rafters to the house roof rafters.

Because of the increased snow, roof, and wind loads that are created by adding a roof, many building departments require the services of a local architect or engineer to design the plans for porch roofs.
Adding a Roof Over an Existing Deck
When we build a deck on the house in the summer sun, we realise we need shade to enjoy the outdoors. How hard is it to instal a deck roof for shade? Depending. If you have a single-story home, adding a roof may require a gable (A-frame) roof and roof tie-in. That's a complicated DIY project. Adding a roof to the side of a 2-story home may be "doable" depending on your carpentry skills. This week, I'll walk through the steps of building an easier two-deck roof and offer tips.
- Apply for permits with your local building department. You'll need a building permit and a sketch of your addition. You'll need to fill out forms with lumber sizes and spacing. Most building departments will help with permit questions. Once you have permits and a material list, get your supplies. Hitch Property Constructions has a wide range of decking services Melbourne services.
- Ledger board setup. Rafters are attached to the ledger board. It attaches to your house's side. Remove siding to make room. Mark the studs. These studs will be ledger board anchors. Ledger board must be properly secured to support rafters. Use 4" lag screws or Ledger Locks instead of nails. This is a new, purpose-built product. Most municipal building departments will accept them instead of lag screws or carriage bolts, and they save me time on the job.
- Beam construction. Two areas need extra attention because of the roof's weight. The first is the house-attached ledger board that supports roof rafters. Other is the rafter support beam. Distance from the ledger wall determines the beam's size. The longer the span, the larger the rafters and heavier the beams. In the photo, I used 2x8 rafters to span 12 feet. Front support beam was 3 2x10s. 20-foot beam A large, finished beam is heavy and needs good support. Four 8s were used "Fiberglass columns. Each column is rated at 10 tonnes, which may seem excessive, but considering the roof's weight and the possibility of wet snow, it's about right. This beam should be built on the ground and lifted by machine. You can build it piece by piece, even by yourself (as I did). I built 3 temporary supports, then attached the house's sideboards to the beam, and built the beam one or two boards at a time (depending on the weight and how early in the day it was). I used as I hung each of the nine boards. I'd attach it to the end board or another board. I used 4.5 "Header Loks tightened it up. (Once tied, it won't be straight.) Stretch a string and use boards to straighten it. This helps with step 2.)
- Rafters. To get the rafters flat on the beam and the birdsmouth flush, you must know the roof pitch. I'll spend extra time calculating the pitch where the rafter hits my ledger board. Once I have it, I'll temporarily tack it up and scribe the birdsmouth's size and shape. Once I get it right, I use that board as a pattern for subsequent rafters. Make sure your beam is square to the house before setting rafters. Use an engineered rafter hanger to support the wall-mounted rafter end. Filling every strap hole with a nail will please the building inspector. On the beam side, you should use a "hurricane" clip.
- Attach sub-fascia. (Here's a helpful hint: Use a string to mark the desired length on all of the rafter tails.) My typical measurement is ten and a half inches, which gives me an overhang of approximately one foot once everything is finished. You can achieve a nice straight line by marking the ends of your rafters with a string that has been stretched out. After that, cut them down to size and nail them onto your sub-fascia. You are now prepared to start decking.
- Putting decking up on your roof. The majority of decking is done with OSB measuring 7/16 inches. Use galvanised 6 or 8 penny nails and make sure to nail a consistent pattern of at least five nails in the centres and double that number on the edges. Use galvanised nails. Always remember to stagger your joints so that no adjacent succeeding row of OSB ends up on the same rafter that was previously used for a joint. This will prevent any potential structural issues.
- Felt and shingles for the roof. Install a weather guard barrier along the roof's perimeter at least three feet out from the edge before you cover it with felt or any other type of approved barrier (front edge and both sides). The accumulation of ice and snow on a roof will not allow water to seep back up under the shingles if this measure is taken. Always make sure to follow the installation instructions when working with felt and shingles.
- Putting up the framing for the gable sides. On the sides, you will need to frame in that area from the sideboards all the way up to the edge of the last rafter, and then cover it with OSB that is 7/16 inches thick. Simply stand your 2x4s on edge and leave a gap of two feet between each one. OSB should be used as a covering, followed by an approved house wrap. You are going to need that house wrap because it serves as a moisture barrier for the inspection of the "veneer." Without it, the item will not pass inspection.
- Make sure that both the framing and the veneer are inspected by calling: At this point, you should start scheduling your inspections. Building inspectors will look for many of the things that have already been mentioned in the preceding sections, including the following: A house wrap for the veneer, the right size lumber, the right amount of space between the rafters, the right kind of rafter hangers, the right kind of hurricane clips, and the right kind of ledger fasteners.
- Final touches; once all of the inspections have been passed, you can instal the siding on the gable ends. Install the fascia board and soffit in your home. The very last thing that needs to be done is to instal a ceiling and then wrap your beam with trim coil. In the following post, I will detail each of those steps.
Reasons To Build A Roof Over A Deck
As you might expect, there are a lot of perks that come along with having a roof built on top of your deck. The most important reasons why you need a roof over your head are as follows:
Protection From The Sun And Rain
Protecting themselves from the heat of the sun and the elements is the most common motivation for constructing roofs over decks. Even on the cloudiest or wettest days, you can sit outside and take in the natural surroundings if you have some sort of covering. Finding some shade on your deck in the middle of summer, when the sun is at its highest point in the sky, is a wonderful opportunity to relax with the people you care about most in the world.
Barbeque Throughout The Year
The barbeque season does not have to come to an end when the fireflies leave if you have a roof installed over your deck. Even when the weather isn't particularly warm or dry, you'll still be able to have a good time barbecuing throughout the year. It is possible that food will take a little bit longer to cook during the cooler months; however, the wait will be well worth it for some delicious burgers, ribs, or vegetables cooked on the grill. Check out our Melbourne decking services services here.
Dry Clothes Outside
If you prefer to air-dry your clothes by hanging them outside rather than putting them in the dryer, installing a roof over your deck will provide the ideal protection from the elements on days when there is precipitation in the forecast. If you dry them outside under the roof, you'll be able to cut down on the amount of money you spend on electricity.
Help Plants Grow
When spring arrives, people who have a green thumb will also appreciate having a covered deck. You can acclimate the seedlings and plants to the conditions by putting them in a protected location and making sure they get some sun every day. This will allow you to adapt the seedlings and plants to the conditions.
How To Build A Shed Roof Over My Existing Deck
It is highly recommended that you do not construct the roof on your own unless you have previous experience doing so for residential buildings. On the other hand, you might be interested in learning the steps involved in the process of how it's done. Have a look at our detailed guide that will walk you through the process of constructing a shed roof over your already existing deck:
- Prior to starting, confirm that your roof's overhang and pitch angle match those of the house.
- Set up the post base connectors. These are used to join the deck's support posts to the frame. Make sure the frame has the necessary blocking for a strong connection. Connect the support posts to the connectors at the post base. Install temporary bracing to maintain the support posts' position. To hold the header beam, the tops of the support posts should be notched.
- The header beams should be attached to the support posts. For a solid connection, thru-bolts are advised.
- Place the ledger board, which will hold the rafters, in place. It can be installed by bolting it to the house wall and flashing it in place.
- Lay out your rafters after marking and cutting the rafter angle to match the roof pitch. Fix the rafters to the ledger board with nails.
- Using framing nails, join the rafters to the header.
- Installing the roof sheathing over the rafters will create the subroof.
- You can get more information about how to construct a roof over a deck by getting in touch with a nearby roofer if you have any questions. In fact, they'll be happy to respond to any inquiries you might have about any aspect of your home's exterior, including the siding, windows, and doors, as well as the roofing and gutters. Our top priorities are your family's safety, warmth, and dryness.

Roof Over Deck Designs
Please let us know which of the looks featured in the images located in the section above is your favourite. Regarding the layout of your deck, you have the option of selecting from one of three primary kinds of roofing materials. They are as follows:
Because they do not require intricate framing, gable roofs are simpler to construct than other types of roofs. They have gables at each end, as well as sides that slope downward.
Hip roofs are very similar to gable roofs in that they both have sloping sides; however, hip roofs are reconnected without the use of gables. Hip roofs are typically found on barns and other structures. Because they will be visible rather than concealed, the supports for a deck roof ought to have an appearance of completion.
Because it is the only option for deck roofing that is compatible with the architecture of many homes, this is the option that is used the most frequently.
FAQs About Building decks
Can I put a roof over my deck? In most cases, yes! If you're looking to add a roof to your deck, you can do this by installing additional supports. Unless you have construction experience, it's best to hire professionals to do this for you.
A cover will protect your deck from rain and potential debris, and it will keep the sun off of it on hot days. This will be a surefire way to keep your deck protected. Plus, if you have any outdoor furniture, a cover will also protect it.
A regular deck can support a certain amount of weight per square foot, but a deck roof adds a lot of weight and requires support. In most cases, larger footings and sometimes more footings are required for a roofed deck. This is why it's best to add a roof during initial deck construction.
For example, if you can add a deck for $10,000, then, on average, it will increase your home value by approximately $7,600—76% of the total. Of course, the true value varies depending on where you live. But a deck in a warm-weather climate is almost always a good idea.
Interlocking deck tiles are a low-cost way to transform your deck into a safer, more attractive space while helping protect the actual deck from wear and tear. For example, installing outdoor tile over a wood deck can help to protect you from splinters while offering the deck protection from sun and wear and tear.
