Adding a roof to your deck can transform it from a simple outdoor platform into a multi-season, weather-resistant living space. But if your home has a brick exterior, attaching the new structure securely becomes more complex. If you’ve been wondering how to attach a deck roof to a brick house, this detailed guide will help you understand the process, tools, safety tips, and structural concerns involved.
Whether you’re a skilled DIYer or planning to hire a contractor, knowing the right way to connect a deck roof to a brick wall is critical for both appearance and safety. Improper installation could lead to leaks, sagging, or even structural damage. This article outlines everything you need to know to get it right the first time.

Why Attach a Deck Roof to a Brick House?
Attaching a roof directly to the structure of your brick home offers multiple benefits:
- Weather Protection: A deck roof provides shelter from rain, sun, and snow, extending the usability of your outdoor space.
- Increased Home Value: A covered deck is a highly sought-after feature that boosts resale value.
- Style Integration: When attached correctly, a roof can blend beautifully with the architectural design of your home.
- Permanent Stability: Brick provides a strong, solid anchor point for attaching a ledger board or beam support system.
However, working with brick presents its own set of challenges that must be carefully addressed.
Things to Consider Before Attaching a Deck Roof to a Brick Wall
Before starting the project, there are a few critical considerations:
1. Local Building Codes
Always check your local codes. Many jurisdictions require permits for adding a permanent roof to a deck, especially when altering the exterior wall of your home.
2. Brick Condition
Inspect your brick wall. Is it solid brick or brick veneer? Solid brick can support structural loads more effectively than a veneer. Loose or deteriorating bricks should be repaired before starting the project.
3. Wall Type
- Solid brick walls consist of multiple layers (wythes) of bricks and can usually support heavier loads.
- Brick veneer walls are a single outer layer attached to a wood frame and may require additional support techniques.
4. Roof Style
Determine the type of roof you want to build:
- Gable Roof: Adds height and allows water runoff.
- Shed Roof: Simpler and slopes away from the house.
- Hip Roof: More complex but visually appealing.
Tools and Materials You’ll Need
Here’s a basic list of what you’ll need to properly attach a deck roof to a brick house:
- Hammer drill with masonry bit
- Ledger board (pressure-treated lumber)
- Sleeve or wedge anchors
- Level and measuring tape
- Lag bolts or structural screws
- Flashing and waterproofing tape
- Joist hangers and rafter ties
- Simpson strong-ties or angle brackets
- Safety gear (goggles, gloves, dust mask)
How To Attach A Deck Roof To A Brick House — Step-by-Step Instructions
Let’s break down how to attach a deck roof to a brick house step by step. This guide assumes you already have a deck in place and are now building a roof over it.
Step 1: Plan and Measure
- Measure the width of your deck to determine the ledger board length.
- Decide the roof slope (minimum of 1:12 is recommended for shed roofs).
- Mark the location on the brick wall where the ledger board will be attached.
Tip: Use a laser level or chalk line to ensure your ledger line is perfectly straight and level.
Step 2: Install the Ledger Board
The ledger board acts as the base that supports the roof rafters or beams.
How to Install on Brick:
- Drill Pilot Holes: Use a hammer drill and masonry bit to drill pilot holes into the brick (not mortar) at intervals of 16–24 inches.
- Insert Anchors: Insert sleeve or wedge anchors into the holes.
- Mount Ledger Board: Align the pressure-treated ledger board with your markings and secure it to the brick wall using bolts or lag screws tightened into the anchors.
Important Note: Do not attach the board to mortar joints. Always anchor into the brick itself for proper support.
Step 3: Add Flashing for Waterproofing
- Install flashing above and behind the ledger board to prevent water from seeping between the house and the board.
- Use waterproof flashing tape and a metal drip edge to seal everything.
- Apply silicone caulk where needed to close gaps.
Step 4: Build the Roof Frame
You’ll now create the skeleton of the roof:
- Attach Posts: If your deck doesn’t already have vertical support posts, install 4×4 or 6×6 posts at the outer edge of the deck.
- Install the Ridge Beam (for gable) or header beam (for shed): Use strong metal brackets to connect beams to the posts.
- Set Rafters: Secure roof rafters from the ledger board to the header beam using joist hangers or hurricane ties.
- Check Slope: Make sure all rafters follow your desired roof pitch for proper water drainage.
Step 5: Add Roofing Materials
- Nail plywood or OSB sheathing over the rafters.
- Install underlayment and your chosen roofing material (shingles, metal, etc.).
- Install drip edges and gutters if needed.
Optional: Add insulation or ceiling paneling if you’re enclosing the space.
Tips for a Seamless and Safe Installation
- Double-check levels and angles: Uneven surfaces can lead to leaks and structural stress.
- Wear safety gear when working with power tools and brick dust.
- Use treated wood or naturally rot-resistant lumber for long-term durability.
- Ensure all hardware is corrosion-resistant, especially if exposed to the elements.
Alternative Methods for Attaching a Roof to Brick
If your home has brick veneer or if you’re concerned about drilling into your brick, consider these alternatives:
1. Freestanding Roof
Build a standalone structure over your deck that doesn’t rely on the house for support. This avoids interference with the brick wall altogether.
2. Brackets Mounted to Wood Framing
Remove some brick veneer to expose the wood sheathing beneath, then mount your ledger board directly to the house framing. Replace and seal the brick afterward.
3. Use Adjustable Roof Brackets
These heavy-duty brackets are designed to fasten through brick veneer into studs behind the wall.
Maintenance Tips for Long-Lasting Results
- Inspect flashing and sealant annually to prevent leaks.
- Check bolts and anchors periodically to ensure they remain tight.
- Clean gutters and downspouts to avoid water buildup.
- Repaint or reseal wood every few years based on climate exposure.
Frequently Asked Questions
Q: Can I attach a roof to a brick house without damaging the wall?
A: Yes, if done properly. Drilling into the brick (not mortar) and using appropriate anchors ensures a secure and damage-free attachment.
Q: Do I need a permit to add a deck roof?
A: In most areas, yes. Contact your local building department before starting.
Q: What’s the best roof style for a deck attached to a brick house?
A: Shed roofs are easier to construct and flash, but gable roofs offer better drainage and aesthetics.
Q: Is it better to hire a professional?
A: If you lack experience with masonry or structural carpentry, hiring a pro is recommended to ensure safety and compliance.
Conclusion
Knowing how to attach a deck roof to a brick house allows you to confidently transform your outdoor space into a comfortable, year-round retreat. While the process requires careful planning and precision—especially when dealing with brick—following the correct steps can ensure a sturdy, leak-free, and beautiful result.
Whether you’re protecting your deck from the elements or building a cozy new hangout spot, securely attaching your deck roof to your brick home is an investment in both comfort and long-term property value.
