We'll show y'all everything yous demand to complete the projection yourself, including how to frame the porch, attach it to your business firm and all of the finishing details. Sure, it'll take a lot of time and work, but in one case it's done, you can beat the bugs and spend more time outdoors during the summer.
Tools Required
Scroll up your sleeves!
A screened in porch is a big improvement, but building a porch is also a big project, one that might eat about of your spare time this summertime. So, nosotros're keeping this how to build a porch blueprint elementary.
Uncomplicated ii×iv wall construction.
Yous can build it with standard dimensional lumber, and it doesn't require heavy beams or circuitous joints. The uncomplicated 2×four walls are light and airy looking. Ii horizontal bands of 2x4s set 10 in. from the top and bottom of the wall, add a blueprint element and stiffen the 2×4 framing enough to support the manus-built trusses.
With this how to build a porch pattern, at that place's no need to precisely marshal the overhangs. And the exposed rafters and open soffit look great on many house styles. Plus, to create the optimal relaxation spot for your porch, attempt out these ten tips.
The total cost of this how to build a porch was $half dozen,500, merely you lot could salve hundreds of dollars without sacrificing quality by substituting treated decking for the cedar or using tongue-and-groove pine rather than cedar on the ceiling.
Straight forward construction.
Even though how to build a porch project is a large project, most of the construction is straightforward. If you've congenital decks or sheds, y'all'll be able to tackle this job with conviction. In this how to build a screened in porch article, we'll testify you the fundamental steps for building this porch. Study the drawings and photos for more details.
The tools you lot'll need:
The screened porch offers a nearly unobstructed view of the outdoors and you'll need a full ready of basic carpentry tools, a circular saw and a drill to build this porch. In addition, a reciprocating saw, a tabular array saw and a power miter box will make the job go quicker and requite you better results. To reach high places safely and easily, we recommend renting a rolling scaffold system for a calendar month.
Projection pace-by-step (21)
Step 1
Plan ahead to avoid structure headaches
You tin add this screened in porch to about any house, just attachment details may vary from what we prove here.
- On most two-story houses, you won't accept to worry about tying into the roof, simply you lot may have to situate the porch advisedly to avoid covering a window.
- The house roof sloped 5 in. per human foot (this is called a 5/12 slope) and extended 18 in. at the overhang. Your roof may vary from this, and the details of how the porch ties in will vary also.
These illustrations above show the plans for the screened in porch, deck framing, gable framing, ledger, truss cake, side walls and the end wall. To print these how to build a porch program, see Boosted Information at the cease of this story.
Step two
Tips for joining the screened in porch and house roofs
If you're not sure how to neatly join the screened in porch and firm roofs:
- We recommend hiring an builder to help work out the details.
- Another option is to build a full-size mockup of a roof truss out of inexpensive and lightweight 1x4s. Figure out where the pinnacle of the wall plate would be if you built the porch co-ordinate to our plans (Figures A – H). Then support the mocked-up truss at this height to encounter how the porch overhang meets the roof.
- If you don't similar the way the overhangs intersect, adjust the level of the deck slightly, alter the wall summit or change the width of the overhang.
- Contact your local edifice inspections department to find out what's required to obtain a building permit.
- Start this procedure at least a month before yous plan to build. This will let enough time to work through potential problems.
Step 3
Build the deck foursquare and level and assemble the perimeter joists
Install the ledger board.
Start by marking the ledger lath location on the house wall. We located the elevation of the ledger board 90 in. beneath the bottom of the soffit. On our house, this left a 6-in. footstep downward from the patio door to the deck surface. Remove the siding and adhere the ledger with i/two x 4-in. galvanized lag screws (Figure D). Brand sure it's perfectly level. If the ledger attaches to concrete, predrill holes and insert atomic number 82 shield lag screw anchors earlier installing the lags.
Outline deck frame and set beams.
Later on you mount the ledger, use stakes and string lines to outline the deck frame according to the dimensions in Figure B and mark the footing locations. A few days before you plan to dig the footings, call 411 to have underground utilities marked in the vicinity of the porch. Your local building department will specify how large and deep the footings should exist for your climate and soil weather. Cascade a concrete pad in the bottom of each ground hole afterwards they've been inspected. Let the concrete gear up overnight.
Assemble Frame.
Next, choose the vi straightest 2x10s for the perimeter beams. Cut the 2x10s for the two side beams to length and nail the pairs together. Use 16d stainless steel or double-dipped galvanized nails for all of the joist framings and to attach the joist hangers to the ledger board. Residuum i end of each side beam in the double joist hangers and prop them upwards until level with a stack of forest.
Stride iv
Install the joists and joist hangers
Boom through the joist hangers into the beams at the house to hold them in identify. Then connect the reverse ends of the two beams at the front end with a 2x10 cut to the aforementioned length as the ledger. Adjust the resulting frame until the diagonal measurements are equal.
Then brace the frame confronting stakes pounded into the footing to hold it square while you install the treated posts, joists and decking. Sight along the outside rim joist occasionally and arrange the length of the joists every bit needed to keep the front rim joist direct.
Step v
Cut abroad the overhang and siding to make way for the porch
Y'all'll have to determine whether to cut a slot where the porch walls meet the siding. If your siding is stucco, brick or stone, you may desire to butt the walls to the siding.
Make a mark 1-five/8 in. out from the deck on both sides. Then make some other mark 5-ane/8 in. inside the kickoff marker. Describe plumb lines up from these marks and cut a five-ane/8-in. slot through the siding but not the capsule. Ready the saw blade just deep enough to cutting through the siding just. Remove the siding. Waterproof the slot with No. 15 edifice paper.
Step 6
Cut away the roof
If your house has an overhang, you lot'll accept to cutting it dorsum flush to allow the innermost truss to fit against the wall. Start by removing the soffit and fascia boards above and several anxiety to each side of the deck. It's easier to remove extra soffit and fascia boards and patch them dorsum after the porch is washed than to calculate cutoff points now. After the soffit boards are removed, use a level to plumb upward from the house wall to the underside of the roof boards, in line with the outside edges of the porch.
Mark the two points. So drive a long spiral or nail up through the roof boards at the two marks. Snap a chalk line betwixt the nails and remove the shingles below and virtually 6 in. above the line. Chalk a new line and remove nails forth the line. Then saw forth the line and pry off the roof boards. Exist certain to clothing safety glasses and hearing protection when you're sawing. Finally, cut off the rafter tails flush to the house wall.
Step seven
Construct a jig to gather the roof trusses
Prime number Before Painting.
Prime and paint the truss parts, wall frame and screen stops earlier associates. Prime the woods with a special stain-blocking primer such every bit Zinsser'southward oil-based Encompass-Stain. And then brush on a coat of acrylic outside house paint. Brand sure to prime every cut end as you piece of work; otherwise, these areas will absorb moisture and crusade staining. Nosotros prefinished the roof boards with an oil finish (Cabot Clear Solution Natural).
How to construct the roof truss jig:
It's easiest to assemble the roof trusses first, using the deck platform every bit a work surface. Screw ii sheets of plywood to the decking and use the dimensions in Figure J to chalk lines indicating the top of the rafters and the bottom of the 2x6 crosstie. Cutting triangular blocks and spiral them to the plywood to agree the rafters in alignment as you assemble the trusses.
Step viii
Build the trusses
How to use the jig:
Cut a rafter using the dimensions in Figure J and use it as a blueprint to mark the remaining rafters. Place a pair of rafters in the jig and spiral the tops together. Next screw the 2x6 crosstie and 2x8 spacer to the pair of rafters. Keep the crosstie screws clear of the bolt hole locations. Consummate each truss by screwing some other pair of rafters on top.
Assemble the rafters and trusses.
Check the ends and tops of the rafters as you lot assemble the trusses to make sure they're perfectly aligned. The trusses must exist identical so that your roof boards and soffit trim will line up. Finally, elevate the truss on blocks of wood while you drill a pair of 1/2-in. holes into each end of the crosstie for the carriage bolts (Effigy J). Run the i/two ten five-1/2-in. carriage bolts through the rafters and crosstie ends and tighten the basics.
Footstep nine
Frame the walls accurately for polish associates
Since the wall framing for this screened in porch is the finished surface, information technology's worth taking a little actress time to make the framing material look good. We chose the nicest cedar 2x6s we could find and ripped them into 3-1/2-in. and 1-1/ii-in. boards. Nosotros did this to create sharp, clean edges (we also ripped off all the factory rounded edges).
Cut the studs and crosspieces to length and screw the walls together (Figures F – H). We used a power miter saw for make clean, foursquare cuts, only a circular saw will work also. Use a crosspiece as a spacer when you're attaching the studs to the top and bottom plates. Then cutting a x-in. spacer cake to position the crosspieces for associates.
Pace ten
Plumb and brace the walls
Stand the walls and screw the wall corners together. The key to continuing the walls is to check and double-check along the way to make sure they're straight along their top and bottom plates, perfectly plumb and square, and securely braced. First by positioning the walls with their outside edge flush to the deck and screwing them downwards. Adjacent, spiral the corners together, making sure the pinnacle plates of adjacent walls are fifty-fifty with each other. Utilise a long level to plumb the walls while you attach diagonal braces to hold them in position. Leave the braces in place until after the covering is consummate.
Step 11
Attach the Trusses
You'll need helpers for this step.
Round up a couple of strong helpers to assist in setting the trusses. Start past mark the position of the trusses on the top plate and onto a 16-ft. 1x4 (you lot'll use the 1x4 to caryatid and position the tops of the trusses equally you stand them upward). The first truss simply butts to the firm wall. The outermost truss aligns with the edge of the top plate, and the iii interior trusses are centered on the studs below. Set the outset truss against the house and advisedly centre it so that 1-i/ii in. of the bottom 2x6 overhangs the tiptop wall plates on each side.
Installing the showtime truss.
Screw the truss to the tiptop plates. Then use a straightedge and level to stand the truss perfectly plumb and brace it to the roof. Make sure this caryatid is deeply screwed to the roof and the truss because the remaining trusses will exist supported by this truss until the roof tie-in framing is complete.
Install the remaining trusses.
Lift the remaining trusses onto the top of the walls and residual them on the first truss. Slowly and carefully slide the outermost truss to the outside end of the porch. Marshal the marks on the 1x4 with the truss at the firm and the outermost truss and screw it to the trusses.
Center the outermost truss on the walls and toe-screw it to the meridian plate of the walls. Stretch a cord line between nails at the tiptop of the ii trusses. Align the remaining trusses with the cord line and the marks on the 1x4 and acme plates and screw them in.
Step 12
Line upward the necktie-in framing with the porch for a seamless blend
One of the trickiest parts of the porch structure is joining the two roofs. The fundamental is to extend lines from the new porch and mark where they intersect the existing roof. Exercise this by using a taut string line or a long, directly board. Call back to raise the tie-in framing on the existing house roof ¾ in. above the porch framing to compensate for the difference in thickness of the iii/four-in. plywood and 1-1/two-in. roof boards, so utilise iii/4-in.-thick spacer blocks to raise the line to the correct tie-in framing height.
Step 13
Install the ridge and rafters
Cutting the 2x8 roof plates. If you're not good at calculating roof angles, start by estimating the angles and cut the plates an extra six in. long. So ready them in place, remark the angles and recut them until they fit. Spiral the roof plates through the roof boards into the rafters below. Next measure out for the ridge, approximate the angle and cut it a little long. Trim the angle to fit and spiral the ridge rafter to the offset truss and roof plates. Complete the tie-in past installing a pair of rafters. The framing should exist exactly 3/four in. to a higher place the top of the trusses.
Step 14
Install the roof boards
To bevel the beginning roof lath, set your table saw or circular saw to 23 degrees and rip a bevel on the groove edge of the board. Align the lath with the ends of the trusses and boom it with 16d galvanized nails. Install the remaining boards, making sure to snug the joints tight before nailing them. Allow the boards hang out past the final truss to form the gable end overhang. Cutting the last board on each side to fit at the summit.
When you're done installing the roof boards, snap a chalk line at the gable (outer) end and saw them off to leave an 18-in. overhang. Finish the gable end overhang by installing a pair of rafters and the 1x3 trim. Concord the gable finish rafters tight to the underside of the cutoff roof boards and screw through the roof boards to hold the rafters in place. Then cutting 1x3 trim to cover the end grain of the roof boards. Extend the trim effectually the corners and return information technology along the roof edge to the business firm.
Step 15
Pay attention to flashing and roofing details for a watertight task
Building the tie-in framing on acme of the existing shingles is a good way to keep the house waterproof as you construct the porch, but when information technology comes time to install the roofing you lot'll take to cut the shingles along each of the valleys with a hook-blade utility pocketknife. Then pry loose the cutting shingles to make a wide path for the valley flashing.
Embrace the tie-in framing with 3/4-in. plywood. Add blocking every bit needed and make full in the triangular areas between the existing roof and the new roof.
Step 16
Install flashing in the roof valley
Nosotros won't go into roofing details here (so check out our proficient guide for how to roof a business firm). In general, cover the eaves and valley with strips of a waterproof membrane (an ice-and-water barrier) and install the sheet metal valley. Place roofing nails most 12 in. apart forth the edge of the metal valley. Cutting a short piece of valley metal to complete the elevation on each side, overlapping it nigh 6 in. onto the long piece.
Staple No. 15 building newspaper to the residual of the porch roof, starting at the bottom and working upward. Overlap each row 3 in. onto the i below. Install shingles to match the business firm. Follow the manufacturer's instructions for starting, overlaps and nail placement. Use 1-in.-long galvanized covering nails to avoid nailing through the tongue-and-groove ceiling.
Pace 17
Fill in the porch gable ends
Comprehend the triangular opening in the truss higher up the house wall by edifice a 2x2 frame and nailing 1x6 natural language-and-groove boards to the back. So slide the frame into the opening and screw it into place. Make full the triangular infinite in a higher place the outside wall with a 2x4 frame (Figure C).
Then staple screening to information technology and comprehend the screens with stops, just equally you lot exercise with the walls below. Practice on scraps to brand accurate patterns for the steep angles. And then transfer the angles to the actual framing members. You lot may have to cut these angles with a handsaw; they're too steep for a miter saw unless you build a special jig.
Stride xviii
Attach trim and sill to the outer walls
Nail a 2x10 trim lath over the exterior joist, ane-1/2 in. below the summit surface of the deck. Cut a 2x4 sill piece to width and bevel the summit on a tabular array saw. Miter the ends and nail the sill to the top of the 2x10 trim board.
Step 19
Trim corner details
This illustration shows how the corners are assembled and the trim is installed.
Pace 20
Staple the screen to the walls
The charcoal aluminum screening nosotros used is potent and long-lasting, merely yous take to handle it carefully to avoid creases and dents. Carefully unroll the screen on a large work surface and cut lengths about iii in. longer than you need. Reroll each piece and comport it to its location.
Outset by tacking the two corners, making sure the screen is square to the opening. Then stretch the screen slightly and staple the sides, top and bottom. Place one/4-in. staples every 3 in.
Pace 21
Adhere 2x2s over the framing
After you stretch and staple each section, cut off the excess screen with a abrupt utility knife. Then encompass the edges with 2x2 trim pieces. We screwed these on to allow for easy removal for future screen repairs, and the trim covers the staples along all of the edges. Frame and screen the outer gable finish post-obit Figure C.
Screen door details:
If you use a wood door like ours, start by trimming it but plenty to fit in the opening. And then ready it in place and mark the door for final fitting. Use a abrupt airplane or belt sander to trim the door. You may have to repeat this process a few times to go a skilful fit.
Smash 1/2 x 2-in. wood stops to the framing at the door opening. Then hang the door using galvanized or brass screen door hinges. Mountain a latch and door closer to complete the job. Plus, check out these other ten inviting screen porches, rooms and lanais.
