If you’re thinking of doing your own roof replacement, there are a few things that you’ll need to know first. Roof replacement isn’t necessarily easy, and if you’ve never worked on your roof before, you’ll want to have someone help you who has some experience. Without experience, you could make a mistake that causes your roof to leak, and the structure of your home could become damaged.

Today we’re breaking down some of the pros and cons and things you need to consider before you decide to DIY your roof replacement. While it’s not something that everyone should do, there are many advantages to re-roofing your house on your own if you’re able to.

Advantages of DIY Roofing

While DIY roofing is no small task, especially if you have a large home and roof, there are several advantages that DIY roofing does offer. One of the biggest advantages and the advantages that most people think of when they think of any DIY project is cost savings.

Cheaper Cost for Replacement

On average, a new roof installed by a professional team can cost anywhere from $15,000 to $30,000. Not all of that cost will be labor, and the range of cost is often associated with material quality. Still, for the most part, the labor associated with a roof replacement project will make up a good portion of a project’s total cost.

Disadvantages of DIY Roofing

While there are definitely positive things associated with DIY roofing, there are also some negative factors to consider before you get too deep in a DIY project. Some obvious disadvantages to DIY roofing include the time it will take to complete, the work that it will entail, and of course, any hidden expenses associated with working on the drip edge, vents, and other areas.

Cost and Quality of Materials

Asphalt shingles can be purchased at several different places. Most commonly, homeowners that replace their roof on their own will purchase shingles from a hardware store such as Home Depot, Menards, Lowes, or other similar stores. Another great place to find shingles and other materials is at your local lumber yard. A lumber yard may also be able to offer you a good deal on the cost of the shingles and materials.

The downside to purchases the shingles yourself is that most roofers are affiliated with roofing material companies. In this case, they’re able to purchase shingles and materials at a discount because of their affiliation, thus helping you get your roof done for cheaper.

Time Needed for Roofing Project

Roofing a house takes a good amount of time. Especially if you’re doing the project on your own, you might be able to get some friends to help out or even a few family members. Still, because they likely aren’t roofing professionals or because they don’t have any experience, you’ll need to take the time to teach and explain how you need the job done. A professional roofing crew can whip out a roofing project in just a few days. A crew of your closest friends and family may take two to three times as long to complete the same project. You must work as quickly as possible because of the damage that can occur if your roof comes in contact with rain or snow before you finish getting all the shingles installed.

Steps to Re-Roofing Your Home


If you’ve decided you’re up to the job of re-roofing your home, here are the steps that you’ll need to follow to be successful! There can be quite a bit that goes into a roofing process, so be sure to consult other sources before tackling the project on your own, especially if you don’t have any prior experience. It’s best to have someone show you the ropes on your very first roofing job. Here’s an overview of the steps:

  • Choose and obtain your materials
  • Remove the old roof
  • Inspect the wood decking
  • Install underlayment and drip edge
  • Install shingles
  • Cleanup and perform a final inspection
  • Dispose of all trash

Choose Your Materials

First up, you’ll want to shop around for the right roofing materials for your home. There are plenty of different options out there regarding material, color, cost, and design. Don’t be hasty in your decision; the wrong material might not look good on top of your house and could be cheap material that won’t last long enough.

Remove Your Old Roof

Next up, you’ll need to secure a dumpster or trailer where you can put your old roof as you tear it off of your home. Remember that you should be ready to get the new roof installed before it rains or snows. Be sure to check the forecast before you decide to remove your old roof.

Inspect the Wood Decking

You may not have noticed any leaks on the inside of your home, but now that the wood decking is exposed, it’s good to check around for leaks or damage to the decking that could have occurred since the last roof installation. Be sure to get the wood decking in good shape before installing the new materials.

Install Underlayment and Drip Edge

After the wood decking checks out, you’ll be ready to get the underlayment and drip edge installed. Both of these materials are essential to the success of your roofing project. Underlayment is a tarpaper material that helps to insulate your roof from the weather and keep your shingles in good condition. A drip edge will need to be installed wherever there are high-traffic runoff areas such as dips and valleys in your roof. To know where they should go on your new roof, pay attention to where you take them off your old roof.

Install Shingles


Shingles can be installed next. Shingles are always installed from bottom to top to ensure proper overlay. Be careful while you’re installing the first few rows of shingles because this is when you’ll be most likely to fall off or get injured. If you’re on a steep roof, consider installing the first few rows from a ladder, even if it takes you a little bit longer.

Cleanup and Perform Final Inspection

After you’re finished with shingle installation, you can clean up any remaining garbage or extra materials and perform the final inspection. Look for any damaged shingles, spots you missed, or places that don’t look right. It’s better to get your roof fixed and in perfect condition before any precipitation has the chance of leaking into your home.

Dispose of Trash

When you’re satisfied with the job’s quality, you can move ahead with the rest of the clean-up and schedule your dumpster to get picked up. If you chose not to use a dumpster for the project, then you’ll need to hall all of the trash to your local recycling or landfill facility, depending on city ordinances.
