Ready to upgrade to a metal roof?
We’ll cover everything you need, from picking out your materials and planning to execute the installation step-by-step. So roll up your sleeves and let’s start: here’s our DIY guide for installing a metal roof.
Types of Metal Roofs
Metal roofing is preferred for house owners because of its strength and long life. Several types of metal roofs are available, each with advantages and disadvantages.
Standing seam metal roofs feature panels that run vertically from the roof’s ridge down to the eaves. The seams between the panels elevated above the panel surface, provide an additional shield against water intrusion.
This type of metal roof can withstand strong winds and, with proper upkeep, has a long lifespan of up to half a century or more. One downside is that standing seam roofs tend to be more expensive than other types of metal roofs due to their complexity in installation.
Corrugated metal panels are made by pressing thin sheets into ridges and valleys, creating a wavy pattern on one side. This helps provide additional strength and stability when installed on a roof structure. These sheets come in various sizes, thicknesses, colors, and finishes to find something that fits your home’s aesthetic needs.

This type of roofing is incredibly resilient. It is designed to withstand harsh weather conditions, like heavy rains and strong winds. Furthermore, it has excellent energy efficiency and can help reduce cooling costs.
Installing a Metal Roof Step-by-Step Guide
To ensure a successful installation of your metal roof panels, it is essential to take the following steps:
Step 1: Gathering the Necessary Tools
Tools are an essential factor in the success of any project. To begin your metal roof installation, collect all the necessary tools for the job. These include:
- Safety glasses
- Roof shears or snips
- Tin Snips
- Roofing nails
- Roof jacks or trusses
- Chalk line
- Clip fasteners
Step 2: Removing the Existing Roof Covering
This can be done by either tearing off shingles or panels or by scraping and cleaning them off. If you are replacing an asphalt shingle roof, inspect for signs of water damage before proceeding with the installation. Examining any leftover nails from the prior roofing material is also a must.
Step 3: Installing the Underlayment
Once the old roof covering has been removed, installing the underlayment is time. The type of underlayment used will depend on your climate and local building codes. Generally, felt paper or synthetic underlayments are best suited for metal roofs in most climates.
They provide additional protection against moisture penetration and help prevent condensation buildup between the deck and metal roofing panels. Make sure all seams are properly sealed using tape or caulk before installing panels or shingles over top of them.
Step 4: Securing the Starter Strip
After laying down your underlayment material, you’ll need to secure a starter strip along one edge of your rooftop for metal panels or shingles to be installed correctly later on during the installation. A starter strip provides extra support at this crucial point where panels meet each other.
This prevents wind uplift forces over time which could lead to leaks in future years if not appropriately secured initially. Most starter strips come pre-cut, but you can also cut them yourself depending on what size panel widths you plan on using when installing your new metal roof system.
Step 5: Installing Panels/Shingles
Now comes the time for installing individual pieces onto the rooftop, which requires careful attention to detail to ensure everything fits. For standing seam roofs, use special clips explicitly designed for the purpose. At the same time, corrugated steel sheets should screw into place with appropriate fasteners, such as self-drilling screws and washers, according to the manufacturer’s instructions.
Stone-coated steel tiles require adhesive spread across the back side of each tile and then pressed firmly onto the substrate. This creates a solid bond for holding place securely even high winds and rain storms occur throughout the year. Finally, aluminum shingle roofs are usually nailed directly into plywood sheathing underneath after being covered by a layer of ice shield membrane.
Once all pieces are installed, take a few moments to inspect the entire area and double-check that no mistakes were made. Finish every part of the system, including flashings, valleys, ridges, eaves, drip edges, etc., to ensure it looks good overall.
