Putting a roof on your own home might seem like a cost-effective and rewarding project, but it's important to understand the complexity and effort involved.


This guide provides a comprehensive look at the materials, costs, and steps needed for a DIY roof installation so you can do it correctly. Our goal is to make the process clear so you can decide whether installing a roof yourself is the right choice or if hiring a professional is better.


Things to Consider Before Starting DIY Roofing


  • Safety Risks: High risk of severe injuries without proper training and equipment.


  • Limited Experience: Professionals have the expertise to identify and address issues.


  • Minimal Cost Savings: Costs for materials, warranties, rentals, and repairs can outweigh savings.


  • Time and Effort: Roofing is physically demanding and time-consuming.


  • Building Codes: Professionals ensure compliance with local regulations.


Safety Precautions


Before starting any roofing installation, it is crucial to consider safety. Ensure you have the necessary safety equipment, including a harness, hard hat, work gloves, safety glasses, long pants, and a tool belt. Working with a partner or team is recommended for additional safety and efficiency. Always check weather conditions to avoid working on a wet, windy, or extremely hot roof. Stable terrain around the foundation is essential for safe ladder placement.


Pre-Installation Preparation


Proper preparation is key to a successful DIY roofing project. Start by mowing the yard and clearing debris to ensure a clean working environment. Move patio furniture away from the house and cover any fixtures that cannot be moved. Take photos of the driveway and surrounding areas to document any existing conditions. Identify exterior power sources and designate a staging area for materials. Ensure you have access to necessary items in the garage and verify proper ventilation to prevent hot air from being trapped in your home.


Measuring the Roof


Accurate measurements are critical for ordering the right number of materials. Measure the width and length of each section of the roof and multiply these measurements to determine the area. Add the areas of each section together and divide by 100 to calculate the number of squares. Finally, multiply this number by 3 to determine how many bundles of shingles are needed, adding approximately 10 to 20 percent for overage and waste.




For a successful roofing install, you'll need the following tools:

  • Pry bar

  • Roofing nailer

  • Compressor and air hose

  • Extension ladder

  • Utility knife

  • Tape measure


Materials required include:


·  Asphalt Shingles: Primary roofing material used to cover the roof. Ensure you have enough to cover the entire roof, with an additional 10-20% to account for waste and overage.

 

·  Roofing Felt Paper (Underlayment): Provides a protective layer between the sheathing and shingles, helping to prevent water infiltration. Make sure to have enough to cover the entire roof surface.

 

·  Drip Edge Flashing: Installed along the eaves and rake edges of the roof to direct water away and prevent it from getting under the shingles.

 

·  Roofing Nails: Essential for securing shingles and other roofing materials. Be sure to use nails that meet code requirements and consider buying in bulk.


·  Roof Sealant: Used to seal joints, flashing, and other areas where water could potentially penetrate.


Additional materials should be considered based on our professional recommendation and GAF’s guide.


Sheathing: The wood foundation layer, typically made from plywood or OSB, to which shingles are attached. Necessary for replacing any damaged areas of the wood deck.


Roof Leak Barrier: Protects vulnerable areas like eaves and valleys from ice dams and wind-driven rain.


Starter Strip Shingles: Installed around roof edges to prevent shingle blow-off.


Hip and Ridge Cap Shingles: Used to protect and finish the hip and ridge areas of the roof.


Flashing: Redirects water away from areas such as chimneys, pipes, and valleys.


Roof Ventilation: Vital for preventing overheating and moisture build-up in the attic.


Fascia Board: Protects the end of rafters or trusses and supports gutters.


Roof Ripper: Useful for removing existing roofing materials quickly and efficiently.

 



Step-by-Step Installation Process


1. Tear Off the Old Roof


Begin by tearing off the old roofing materials, including shingles and underlayment. Use large tarps to protect plants and landscaping from debris. Remove all nails or pound them flat to prepare for the new installation.


2. Repair the Decking


Inspect the roof decking for any signs of water damage or rot. Replace damaged sections with new plywood or OSB of the same thickness. Secure the new decking with screws or nails.


3. Install Drip Edge and Underlayment


Fasten drip edge flashing along the eaves and install underlayment over the decking. Ensure the underlayment lies flat and overlaps properly to prevent water infiltration. In regions with extreme weather, consider using self-stick underlayment for added protection.


4. Install Flashing


Install flashing in valleys and around dormers, vents, and chimneys. Proper flashing installation is crucial to prevent leaks in these vulnerable areas.


5. Lay the Shingles


Start with a row of starter shingles at the eave, followed by the main shingles. Lay the shingles in a staggered pattern, ensuring proper nailing technique to secure each shingle. Follow the manufacturer's instructions for spacing and alignment.


6. Install Ridge Caps


Finish the roofing installation by placing ridge cap shingles along the roof peak. These shingles provide a clean finish and additional protection against leaks.


Common Problems and How to Avoid Them


DIY roofing projects can encounter several common issues, such as leaks, improper nailing, and inadequate ventilation. To avoid these problems:


  • Ensure all nails are driven straight and securely.

  • Use appropriate underlayment and flashing materials.

  • Maintain proper ventilation to prevent moisture buildup.

  • Double-check measurements and alignments throughout the installation process.

Costs and Labor Involved


The cost of installing roofing yourself includes materials, tools, and potential rental equipment. While DIY roofing can save on labor costs, it requires significant time and effort. Comparing the total DIY costs with the cost of hiring professionals can help you decide the best approach for your situation.
