He attached the panels with special roofing screws that have hex heads and neoprene washers for sealing. Youll find these screws where steel or fiberglass roofing is sold. You could also use galvanized steel or plastic roofing panels and install them the same way. Rune screwed treated 2×4 purlins to spacer blocks to support the panels and provide the necessary slope .

    Gutters arent required, especially if the water drains onto your lawn. But if the water falls onto the patio, gutters can prevent splashing. Rune chose PVC gutters because theyre inexpensive and easy to cut and install.

    DIY Porch Roof: Building a Simple Pitched Roof Step by Step

    Make sure that porch roof wont cause harm to the entire building. First of all, check if your house can hold up additional weight. The roof of the house has to be quite stable and strong. Deformations and rotting make the roof unsecure, so that will be quite difficult to attach a porch roof without causing damage to all house. So you have to repair all the damages and apply anti-rot roof covering agents to the house top.

    Ensure that your porch is leveled. If no, you will have to flatten it by repairing the areas which are below the level. In opposite case, you are risking to get an unstable and distorted porch roof.

    Check if there are no external lines of communication, such as phone wires, power, and TV-cables, etc., located in front of your house. If there are some, you have to lay them in the way that all the cables are hidden. Nearby trees can also make attaching the roof quite difficult. If so, you have to cut down the branches that can disrupt roof construction process.

    Project Guide: Roof Sheeting

    Help & Advice> Project guides> Roof Sheeting

    Building a porch is a great way to add an attractive entrance to your home and can bring about a number of benefits. But what are the planning regulations involved in building a porch, what are the benefits of building a porch, and how do you build a porch? Read on to find out everything you need, and feel free to get in touch if you have any questions or queries.

    Tips For Purchasing Materials

  • Be flexible. I had originally planned on using 4×4 beams and joists, but local codes wouldnt allow for them, so I used 10×2″ headers and 6×2″ joists, which worked out just fine. Also, be prepared to modify your plan at the store when youre getting your materials, as doing so can save you money. For instance, I chose drywall screws instead of nails because, for some reason, they were less expensive, and they wont try to work themselves back out after a few years. Another substitution I made was choosing 3- and 4-inch deck screws instead of framing nails. Although more costly, they hold much better than framing nails outdoors.
  • Shop around. Shopping around for the best prices for materials was absolutely necessary. In the same town, in an area of fewer than 10 miles, the difference in prices was enormous. Total material costs ranged from $2,200 down to $800.
  • Beware the store associates. Some are aggressive and want to push customers into an insane buying frenzy, bringing up a storm of confusing nonsense that somehow equates spending more to saving more. The lumber store I bought from had an associate who simply made sure I bought the correct materials for the job by looking over my plan and suggesting shorter screws for the joist hangars and a lower grade of lumber for the areas of the patio cover that would not be exposed to the weather. The associate also arranged for delivery, which cost $25.

    Construct A Jig To Assemble The Roof Trusses

    Prime Before Painting.

    Prime and paint the truss parts, wall frame and screen stops before assembly. Prime the wood with a special stain-blocking primer such as Zinssers oil-based Cover-Stain. Then brush on a coat of acrylic exterior house paint. Make sure to prime every cut end as you work otherwise, these areas will absorb moisture and cause staining. We prefinished the roof boards with an oil finish .

    How to construct the roof truss jig:

    Its easiest to assemble the roof trusses first, using the deck platform as a work surface. Screw two 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 2×6 crosstie.

    Prep House For New Roof Framing

    If you install a slanted roof over your deck, your deck roof rafters will have to attach to your existing roof rafters or trusses. To do this, youll have to remove a section of existing roofing materials and sheathing, plus soffit, fascia, and any gutters that are in the way.

    If your new deck roof connects to a flat, vertical face such as a homes exterior wall, youll need a ledger board fastened to a rim joist. Youll need to remove the siding to fasten the ledger. Once in place, the ledger can support beams or joists that will support rafters or trusses for gable or hip roof construction.

    When installing the ledger board, youll need to put flashing over the top edge of the board. This flashing should go up and under your siding. You should use an adhesive to affix it to the sheathing beneath the siding.

    Youll need to bend the flashing to sit flush over the top ledger board edge. The flashing should cover the top half of the ledger board. Once the flashing is installed, the rafters will sit on top of the flashing.

    Install The Drip Edge

    Metal drip edge isnt usually required , but it gives roof edges a nice finished look, prevents shingles from curling over the edge, and keeps water from running directly down your fascia boards.

    Before you install the underlayment, fasten the drip edge that covers the fascia on the eaves. The whole length of the fascia is probably not perfectly straight, so dont snap a line just hold the drip edge snug against the fascia and fasten it through the top into the decking with roofing nails. Nail it every couple of feet.

    Install the drip edge on the gable ends of the roof after you finish installing your underlayment. Start at the bottom side of the gable, and overlap the sections of drip edge a few inches as you work your way up the roof . Use a tin snips to cut the drip edge to size.

    To bevel the first roof board, set your table saw or circular saw to 23 degrees and rip a bevel on the groove edge of the board. Align the board with the ends of the trusses and nail it with 16d galvanized nails. Install the remaining boards, making sure to snug the joints tight before nailing them. Let the boards hang out past the last truss to form the gable end overhang. Cut the last board on each side to fit at the peak.

    When youre done installing the roof boards, snap a chalk line at the gable end and saw them off to leave an 18-in. overhang. Finish the gable end overhang by installing a pair of rafters and the 1×3 trim. Hold the gable end rafters tight to the underside of the cutoff roof boards and screw through the roof boards to hold the rafters in place. Then cut 1×3 trim to cover the end grain of the roof boards. Extend the trim around the corners and return it along the roof edge to the house.
