A porch addition is one of the effective ways to add value to your home. The average return of investment you will get is around 84%. A porch roof installation can definitely beautify your outdoor premises. It will provide a shaded area where your guests can relax and enjoy the outdoors. 

Since your porch is a covered area, you need a roofing option that’s tough and durable. A metal roofing can withstand even the harshest conditions. This blog post covers the reasons why you should get metal roofing installation for your porch addition.

Why Metal Roofing?

Unlike asphalt shingles, metal roofing is more unique. It comes in different styles, designs, and color combinations. Depending on your preference, you can match the style of your porch roof with the main roofing system. When installed correctly, it can last 40-70 years with minimal upkeep required. The lifespan of metal roofs is 2-3 times longer than other roofing materials. 

Metal panels make good material for porch roofing because it is resistant to corrosion and rust. Moreover, it provides energy savings. Metal roofing does not absorb heat in the porch roof, which means they only reflect the sun’s energy. The metal porch roof’s aesthetic appeal will spruce up your home exteriors. Whether you are installing a front side or backyard porch, a metal roof porch cover will offer a myriad of benefits.

How To Install a Metal Porch Roof

To make the most out of your porch roof, it’s important to set up the metal panels properly. Here are the steps to learn how to build a metal porch roof.

Step 1: Measure the Porch Roof Area

First, measure your roof so that you know how much roofing material you need to order. You should take the length, width, and rise of one section. Calculate the slope of your roof as well as the total square foot estimate. Don’t forget to add an extra 10% of additional length for potential waste due to human error.

Step 2: Remove the Old Porch Roof

If you have roof shingles for your porch, start tearing them off from the highest point on the roof. Remove all the shingles, flashings, roof frame, and plywood sheathing. Before you remove the old porch roof, check the weather to minimize the chance of moisture damage.

Step 3: Install the Foundation Posts

Regardless of roofing material, you need to dig deep holes into the ground where you can place foundation posts. A robust concrete foundation ensures the firm positioning of the porch roof. Place the posts into the ground and cover them with concrete to keep them in a vertical position.

Step 4: Install Drip Edges and Eave Flashings

The drip edges or eave flashings are the steel metal strips at the edge of the roof. These materials help protect the façade from various weather conditions. Place the flashings along the eaves and use galvanized roofing nails to secure them. 

Step 5: Install the Metal Roofing Panels

Once the foundation posts and the frame has been installed, you can start adding the metal roof panels. Spread the panels on the perimeter of the porch roof. Begin at the eaves and work your way up. For proper installation, make sure the panels are square to the roofline. The metal roof panels should be installed properly to the frame so that they remain intact. You may cut excess panels where they need to fit. 

To secure the materials, place the metallic or galvanized screws according to the manufacturer’s guidelines. Secure the nails and screws but avoid over-tightening. Apply a silicone sealant if needed. If your area has specific building codes, make sure that you follow them as well.
