How To Attach A Porch Roof To A Mobile Home

Have you ever fantasized about lounging on a front porch, sipping some iced tea and just relaxing as you take in the beautiful scenery outside your mobile home? A dreamy front porch can be the perfect addition to your mobile home, letting you fully immerse yourself in nature while adding extra living space.

But if you want to enjoy your porch without being directly exposed to the elements, you’ll need to add a roof. Attaching a porch roof to a mobile home may sound complicated, but it can actually be a pretty straightforward DIY project if you have the right tools, materials, and game plan.

In this guide, we’ll walk you through the entire process of planning, building, and finishing your own porch roof addition. Who knows, once you complete this project, you may even inspire your neighbors to spruce up their mobile home’s exterior too!

Planning Your Porch Roof

Before you start sawing and hammering away, some prep work will set you up for success. A well-thought-out plan and design can help this project go smoothly while meeting local building codes.

Consider Building Codes and Permits

The first step is making sure a porch addition is even allowed on your mobile home. Building codes can vary by county and city, so check with your local permitting office on any restrictions or required permits. Discuss your plans with them upfront to avoid any costly rework down the road.

For instance, there may be rules about the porch’s height or distance from the electrical meter on your mobile home. It’s better to know these things now rather than after you’ve already purchased materials! Getting the green light from your local officials is key.

Assess Your Mobile Home’s Structure

You’ll need to attach the porch roof securely to your mobile home. This means the structure and roof framing must be sturdy enough to support the weight of the added porch roof.

Inspect the exterior carefully, checking for any sagging or soft spots which could indicate weakness. Pay special attention to the roofline where you’ll attach the porch roof. Reinforce any questionable areas for safety.

Check Porch Level and Stability

Since the porch roof will sit upon the porch itself, the porch foundation needs to be stable, level, and square.

Use a 4-ft level tool to check for flatness across both directions of the porch. Place wooden shims underneath to level it out. The last thing you want is to build the roof on an unlevel porch, so take the time to get this right!

Create a Design and Take Measurements

Now for the fun part – map out how you want your porch roof to look! Consider the size, roof style (like gable, shed, or hip), materials, and any decorative elements.

Also measure the footprint of the porch area thoroughly so you can get accurate measurements for building. You’ll need the length, width, and height. Having precise measurements makes construction easier.

Building the Support Structure

The central framework that holds up the porch roof is key for structural integrity. This includes the posts, beams, and rafters that connect to the mobile home.

Install Support Posts and Pillars

Support posts are vertical structures that hold up the overhead porch roof beams. They transfer the weight of the roof safely down to the ground.

Determine post locations based on your porch design, then dig or drill holes for anchors. Set steel or wooden posts in the holes and hold them plumb while pouring concrete around the base. Let it fully cure before moving on.

You can also use decorative pillars made of materials like fiberglass for a classier look. Attach with manufacturer’s instructions.

Add Beams and Headers

Horizontal beams connect the support posts while holding up the rafters. Check code for beam size requirements. Use hurricane ties to anchor them securely to posts so they don’t shift under the roof load.

Headers are boards that attach to the side of the mobile home, providing an anchor point for the roof. They must be well-secured to wall framing using long lags.

Attach the Top Plate

The top plate is a board that connects the support beams, rafters, and headers. This ties all the structural members together. Use metal connectors to firmly attach the top plate.

Put Up the Rafters

Rafters are angled framing members that meet at the roof peak. They need to link up with the top plate on one end and porch beams on the other. Rafter size depends on the roof span.

Cut each rafter to length before lifting them into place one-by-one. Toenail them with the beams while keeping them properly aligned.

Roofing Materials

Once the underlying structure is complete, it’s time to add the visible roof covering! This protective layer shields the interior porch space from the outdoors.

Plywood Roof Decking

Plywood sheets provide a sturdy, uniform surface to install roofing materials on. Use at least 5/8-inch exterior-grade plywood. Stagger seams and leave 1/8-inch gaps for expansion. Screw the sheets to every rafter.

Roofing Underlayment

Underlayment creates a water-resistant barrier beneath shingles. Roofing felt is an affordable underlayment option. Roll it out across the roof, overlapping edges by several inches. Use roofing nails to secure it.

Shingle Selection and Installation

Now for the fun part – picking shingle colors and styles! The installation method depends on the shingle type, so follow manufacturer instructions. Generally you’ll stagger rows while nailing each shingle into place.

Proper spacing is crucial – shingles laid too close or far apart can lead to weather damage. Take your time to get it right.

Finish by adding flashing along edges and roof penetrations as a protective barrier.

Porch Roof Styles

You have options when it comes to the roof design. Two common styles that work well for porch additions are gable and shed roofs.

Gable Roof

This triangular roof shape has two sloped sides meeting at a center peak. It’s symmetrical and provides good water runoff. Install gable roof rafters at the same length and angle on each side.

Shed Roof

The single-slope shed roof has great simplicity and allows more customizable length and pitch. It can be a budget-friendly option since it requires fewer materials and less complex framing.

Finishing Touches

You’re in the home stretch! A few final touches will get your porch roof looking its best.

Painting or Staining

Adding color through paint or stain gives your roof a polished, complete appearance. This also provides weather protection for wood elements like rafter tails and beams.

Decorative Trim

For extra flair, install decorative elements like crown molding, frieze boards or post capitals using finish nails. This dresses up plain porch posts and complements your mobile home’s style.

Lighting Fixtures

Sconces or pendant lights allow you to safely navigate the porch at night. Hang them from the porch ceiling or mount to sides of the roof. Use exterior fixtures rated for damp locations.

Common Mistakes to Avoid

This project has so much potential for beauty when done properly! Avoid the following missteps:

  • Inadequate structural reinforcement of the mobile home
  • Failing to properly anchor posts and connect framing
  • Using warped or cracked boards
  • Improper shingle installation and overlap
  • Skipping protective finishes or flashing


Building your own porch roof truly achieves the mobile home dream. With the right prep work and diligent construction, you can create a gorgeous addition to enjoy for years to come. Just be sure to follow sound building principles and get your local permits. Before you know it, you’ll be hosting a porch barbecue to show off your handiwork to the neighborhood!
