Gutters arent required, especially if the water drains onto your lawn. But if the water falls onto the patio, gutters can prevent splashing.

Check Some Important Details
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.

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.

Currently, the cost to add a roof over your patio will start at $2,000 and increase from there. Contact a local roofing company to get started and schedule an estimate for your project.
Install The Roof Boards
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.
