Step-By-Step Process to Attach Patio Roof to House

Implementing a perfect patio roof into your home offers enough shade to enhance your living area and increase the curb appeal of your property. 

If you don't know how to attach a patio cover to your house, you may encounter a few problems. These could include choosing inadequate materials that cannot withstand changing weather patterns or faulty installation. Faulty installation can even lead to structural instability with time.

To avoid such circumstances, hire experts who will carry out seamless ways to attach a patio roof to your existing house. Their attention to detail and skill set will give you a functional and aesthetic patio. You can make informed decisions at every step with their tips and advice. 

Here is a detailed guide to help you understand the steps to install a patio roof safely and hassle-free. 

Step 1: Chamfer the Edges of Wood

Adding a patio roof starts with chamfering the edges of rough-sawn wood using a power plane. It adds a touch of elegance to the complete patio structure. 

Following this is a layout of 1x6 decking, 2x6 rafters, and 8x8 posts and beams. It is used to pre-stain the wood with a medium-brown stain.  

Step 2:  Chamfer the Horizontal Beam

The experts make a 15° chamfer on the horizontal beam right at the bearing point for rafters. The beam is then raised into place and secured to the posts. The two outside rafters are then squared into place to provide a base for the rest of the roof. This helps the professionals start the cutting process.

Step 3: Placement of Outside Rafters

At this level, the expert positions and squares the two outside rafters to establish reference points for the roof. By properly placing the rafters, they ensure structural integrity and a leveled roof surface. Once the beam is in place, it cuts off the binds required earlier for instructions.

Step 4: Determine Removal and Attachment Areas

Once the placements are done, professionals assess the shingle, decking, and eave removal areas before the new components are attached. This ensures the proper installation and minimizes any obstruction to the existing structures.  

The new base provides a bearing surface and attachment point for the new rafters. In this step, the opened eave needs to be closed later. 

Step 5: Attach Continuous 2x6 across Existing Roof

After the eave is closed, the bearing point location for the rafter is fixed. Then, the experts secure a 2x6 rafter across the existing roof for extra support. The rafters are installed on the 14" centers instead of the 24" truss spacing. It provides a stable foundation for the new patio roof and distributes the weight uniformly.

Step 6: Pre-cut and Install New Rafters

Going further, pre-cut and new rafters are attached to 14" centers for better stability and ventilation. The well-spaced rafters offer structural integrity and allow proper airflow under the roof. 

Each of the new 2x6 rafters is pre-cut and is placed on a 14-inch layout over the 2x6. It is then attached with an 8-inch structural screw. The professionals attach blocking to the lower side 2x6, leaving a gap at the top for ventilation purposes.

Step 7: Install Ventilation Block

Then, the blocking is set to provide a clear termination for the wall below and a gap at the top for ventilation. Proper ventilation prevents moisture build-up and extends the lifespan of the patio structure. Then a 10" structural screw secures every rafter at the chamfered surface, and blocking gives a tidy look. 

Step 8: Attach Rafters to the Beam

At the end of the new patio roof, the rafters are kept on the chamfered area of the beam. Using 10-inch structural screws, the professionals ensure that each rafter is attached through the top. Blocking is installed between the rafters to enhance the aesthetics and sturdiness, bringing in a polished appearance. 

Step 9: Attach Rough-Sawn 1x6 Decking

In this step, rough-sawn 1x6 decking is attached with ¼" spacing to the rafters. It provides a durable surface for the roof and adds visual appeal to the overall patio structure.  This structural panel ensures that the shingle nails are not visible through the finished surface below. 

Step 10: Install Roofing Components

The experts now install roofing felt, OSB (oriented strand board), and asphalt shingles to match the existing shingles on the house. Properly installing roofing components makes the roof weatherproof and protects it from the elements. 

Step 11: Finish Cut Ends

After installing roofing elements, the experts decide to have an elegant finish for the areas where the eaves are removed. This leads to a clean and coordinated look. A clean finishing detail must blend well with the structure, as the eave terminations and wall area are generally visible.

This step adds a polished appearance to the overall patio roof and blends well with the existing architecture. 

Step 12: Design and Install Custom Connection Plates

Roofing the structure is like adding permanent post-and-beam connections. The experts design and install custom connection plates at the final stage for a functional and visually appealing touch. 

These plates add structural support and are interesting decorative elements for the patio structure.  

Factors to Consider Before Installing a Patio Cover 

When planning to install a patio cover, multiple factors need to be considered.  The structure must be safe, aesthetically pleasing, and functional.  

These factors also influence the design and installation of the new patio roof. It comes in different shapes, sizes, styles, and materials to cater to various preferences and requirements.

Critical considerations while attaching a patio roof to different types of house exteriors-

Attaching Patio Roof to Brick

The whole structure of your home is an important factor to consider when attaching a patio roof. Depending on the exterior walls, there are common ways to attach a patio roof to your house. 

If the brick wall provides support by an internally framed wall, the professionals attach the patio roof by removing the bricks. Further, they fasten the roof to the wall's interior framing, making it sturdy.

When it comes to design, a box-frame patio roof is considered durable and offers a classy look for any brick house. 

Adding Patio Cover to A House with Vinyl Siding

Thinking about how to attach a patio roof to an existing house with vinyl siding? 

Vinyl siding is not designed to bear weight. Thus, it is crucial to have underlying wall studs for secure attachment. One of the most common ways the professionals use is cutting a section of the siding. 

Then, they connect a mounting block to the house's basic structure. It provides a secure base for the patio cover without damaging the siding, allowing flexibility. This prevents cracks and warping. 

Attaching a Patio Roof to A Two-Story Houses

Some patio roofs can be attached by securing them to an existing structural gutter, also known as the fascia method. However, a two-story property is way too tall for this. 

Hence, ensuring that your patio roof's height adheres to building regulations is essential. The roof is fastened to one of the adjoining walls to carry this out. Ensuring that the patio cover's supports and beams are adequate to handle the additional load is essential. 

Generally, the higher structures are more exposed to wind, so the patio covers must be designed to withstand stronger winds. 

Choose the Right Materials for the Patio Roof

The materials chosen for the patio roof determine its durability, maintenance requirements, and aesthetic appeal. You can choose from various materials, such as aluminum, wood, vinyl, and metal.  

Choosing the suitable material is about maintaining a balanced vision with your requirements. You must look for materials that complement the house's architecture and can withstand adverse weather conditions. 

Make sure it fits well within your estimated expenditure for the project. Also, make sure to have open discussions with the experts throughout the material selection process. The professionals always ensure that your expectations are met. 

The varied types of material used for patio covers are – 

Wood

Here comes the best alternative solution: polycarbonate. It is considered to be an ideal glass replacement and helps you achieve a similar look.
