How To Build A Roof On A Pergola In Bracknell

Introduction

A pergola is an open structure with a roof supported by columns or posts. It provides an excellent outdoor living space that can be used for entertainment or relaxation. Building a roof on a pergola can enhance its aesthetics and make it more functional by protecting the area below from the sun and rain.

In this article, we discuss the materials and steps required to build a roof on a pergola in Bracknell.

Pergola Materials

Before building a roof on a pergola, the pergola itself has to be constructed. The following materials are required for building a pergola:

• Posts: Choose 6x6 or larger treated lumber posts to ensure stability
• Beams: 6x6 or larger treated lumber beams should be used for additional stability
• Joists: 2x6 or larger lumber treated joists can be used to span the length of the pergola.
• Knee braces: 4x4 lumber can be used to reinforce the posts and beams.
• Hardware: This includes bolts, nuts, washers, and screws to hold the pergola together.

Pergola Roof Materials

Building a roof on a pergola requires additional materials such as purlins, boards, and roof covering.

• Purlins: 2x4 or larger treated lumber purlins can be used to support the roof covering and span the joists.
• Boards: Choose tongue and groove boards or plywood sheets to cover the purlins.
• Roof covering: The following materials can be used to cover the roof depending on your preference:
• Retractable roofs: These are roofs that can be opened or closed depending on the weather. They can be made of glass, plastic, or fabric.
• Permanent roofs: This includes materials such as metal sheets, asphalt shingles, or tiles.

Installation

To install a roof on a pergola, follow these steps:

1. Determine the grooves. Measure and mark the grooves on the pergola posts and beams where the purlins will be installed. Purlins should be spaced 2 feet apart for optimal stability. Use a square to ensure accuracy.
2. Install the purlins. Attach the purlins to the grooves using bolts, nuts, and washers. Make sure the purlins are level before attaching them to the joists.
3. Install the boards. Attach the boards to the purlins using screws. If using plywood sheets, ensure they are painted or stained to prevent warping.
4. Install the roof covering. Attach the roof covering to the boards or purlins. For retractable roofs, ensure the roof is attached securely to prevent wobbling or excessive movement.
5. Determine the roof slope. The slope of the roof is essential to prevent rainwater accumulation. The slope should be 1/4" per foot away from the house direction. This ensures that rainwater flows away from the pergola and towards the lawn.
6. Install the slope. If attaching the roof to an existing house structure, ensure the slope is attached to the house roof to prevent water from accumulating on the pergola. Use metal flashings to prevent water from seeping through.
7. Need a point. Ensure that you measure and mark the pitch points, apex, and slope angle, so you know where each section needs to go before proceeding to the next step.
