UPDATED ON February 13, 2026

Summary

DIY roof replacement isn’t always feasible. Homeowners who aren’t comfortable working at heights and handling special equipment face significant risks. Roofing also requires permits, materials, and tools such as a roofing nailer, circular saw, utility knife, and safety harness. The process involves removing old shingles, fixing any existing problems, installing underlayment, waterproofing, fastening new shingles, and properly sealing all penetrations or entry points. Restoring existing shingles can also be a simpler and more cost-effective way to improve roof condition.

Asphalt shingles, the most common type of roofing for homes and many businesses in the United States, dry out and break down over time. That means there’s a good chance your roof will need to be replaced at some point in the not-so-distant future.

 

While it’s technically possible to replace an asphalt roof yourself if you have the skill and knowledge, we never recommend handling jobs like these on your own unless you’re a roofer yourself. It’s labor-intensive, potentially unsafe, and could even void your warranty or violate local code.

 

If you’re absolutely committed to exploring this option, you should at least know what you’re getting into before you get started. Find out what the process typically looks like, where Roof Maxx comes in, and what you need to consider before you forge a path forward on your own below.

What Do You Need to Reroof Your House?

DIY roof replacement costs can be surprisingly high. Even though you’re technically getting “free” labor by doing the work yourself, you’re still going to need a lot more than just new shingles. Let’s take a look at common requirements like safety equipment, permits, and more.

Physical Requirements

The first thing you need for DIY roof replacement is the ability to work on your roof. That’s no small task, especially if you don’t feel comfortable working up high. Many people assume they’ll be fine until they get up there, and the worst possible time to realize you were wrong is after a fall.

 

Roofing also requires the ability to lift heavy packs of shingles, which can be more taxing on your back, shoulders, arms, knees, and legs than you might think.

 

Consider that each bundle:

  • Weighs around 45 to 60 lbs at minimum
  • Could weigh up to 800 lbs, depending on the material
  • Can be unwieldy to carry and throw your balance off

What seems like an easy task for a reasonably strong person can quickly become dangerous. The savings that come from doing your own roof are honestly not worth any long-term injury.

Permits

Depending on where you live, you might need a building permit from your city or county. You can check with the city or local building office to find out what permitting is needed.

 

It’s important to make sure that all of the necessary paperwork is in place before you start. If you skip this step, you could expose yourself to fines or other penalties in the future.

Tools

You’ll need the right tools for cutting and securing the roofing materials in place as well as safety equipment to protect you physically. Again, keeping yourself safe is priority number one, which is why we don’t recommend climbing on the roof yourself.

 

If you decide to proceed anyway, you’ll need tools like:

 

  1. An air compressor and air hose
  2. A roofing nailer
  3. A circular saw
  4. A caulk gun
  5. A staple gun
  6. A utility knife and blades
  7. Tin snips
  8. A straightedge
  9. A safety harness and fall arrest system
  10. Work gloves

Tools like these aren’t cheap to buy for yourself, either. Even a cheap roofing nailer will set you back $1-200 or more. Add another $150 or so for a rooftop safety kit for each person who will be up on the roof and costs really start to add up. 

Roofing Materials

The most obvious expense will be the roofing materials themselves. This is another area where homeowners frequently underestimate what they actually need.

 

All of these components are essential:

  1. Underlayment
  2. Asphalt shingles
  3. Sealant
  4. Roofing nails
  5. Drip edge
  6. Flashing for dormers, vents, and valleys
  7. Hook blades
  8. Staples

What’s also important to note is that, in some cases, all of these materials need to be compatible with one another. Not all shingles are designed to work with every type of drip edge or flashing, and vice versa.

 

Some homeowners find that they can actually get a better price by going through a roofer. This makes sense, because most contractors can access volume discounts to help bring costs down.

How Much Does DIY Roof Replacement Cost?

Why should you do DIY Roofing? The primary motivation is savings. The cost of roofing your house depends on everything from the size of your roof to the type of material you choose.

 

Even where you live can have an impact. For example, it’s common for a new roof to cost less in places like rural Illinois than in a major city like Denver, Colorado!

 

On average, the cost of reroofing yourself would run between $2,000 and $6,000. Compare that with paying a roofing company, which would cost between $10,000 and $12,000.

Understanding the Roofing Process

Replacing a new roof is very complicated. First, you need to schedule the job when you know the weather is going to hold out for several days. It’s best to have help so you aren’t doing all of the work yourself, as the process itself can be incredibly exhaustive.

 

Once you’re ready to go, you’ll follow a specific step-by-step process.

1. Tear Off the Old Shingles

  • Remove shingles, nails, and debris down to the roof deck so new materials sit flat.
  • Inspect the decking for rot, mold, leaks, and other signs of damage.
  • Correct any existing problems like these before you move on.

2. Install the Drip Edge

  • Attach metal drip edge along the eaves and rakes.
  • This helps direct water away from the fascia and roof deck.
  • Secure it tightly so wind and rain can’t get underneath the edges.

3. Lay Down New Underlayment

  • Lay underlayment directly over the roof deck for moisture protection.
  • Start at the bottom edge and work upward toward the ridge cap.
  • Make sure to overlap each row so water sheds properly.

4. Cover the Roof With Felt Paper

  • Install felt or synthetic paper over the underlayment.
  • This provides backup protection if shingles fail.
  • Keep the surface smooth to avoid trapping moisture.

5. Install Flashing and Waterproofing at Valleys and Edges

  • Add flashing where any two roof planes meet and along the edges of your roof.
  • These are the main areas that handle the flow of water when it rains.
  • Proper installation is critical for preventing serious leaks and structural damage.

6. Ensure Proper Overlap to Prevent Leaks

  • Overlap all materials according to manufacturer guidelines.
  • Water should always flow over, not under, each layer.
  • Skipping this step can lead to early failure. 

7. Install Your New Shingles

  • Map out your placement in advance with roofer’s chalk
  • Start at the bottom of the roof and work upward in rows.
  • Make sure nails are correctly placed and not driven in at an angle.

8. Trim All Edges

  • Cut any shingle excess so it’s flush with the roofline.
  • Trimming back unnecessary overhang helps prevent leaks.
  • Avoid any potential mistakes, like trimming shingles back too far.

9. Install Any Dormers or Vents

  • Install and flash all dormers, vents, and skylights according to the manufacturer’s directions.
  • Seal these areas especially well since they penetrate your shingles and the roof itself.
  • Don’t rush! It pays to take time and get this step right.

10. Seal Around All Pipes, Vents, and Other Protrusions

  • Install boots or add roofing sealant to any areas where two different materials meet.
  • Check for gaps where water could collect as even small openings can cause major damage.
  • You can test the seal with a regular garden hose or even a container of water.

11. Cap the Roof Ridge

  • Install ridge caps along the peak of the roof according to the manufacturer’s instructions.
  • A properly installed cap helps your roof shed water down onto the ground.
  • Be careful to keep the ridge aligned, or it won’t look right and won’t protect your roof!

12. Check and Seal Your Work

  • Check all shingles, fasteners, flashing, and exposed areas carefully.
  • Seal any remaining entry points well and wait for them to dry before you inspect.
  • A final walkthrough helps catch details or errors you might have missed.

It’s a detailed process, and there’s so much that can go wrong along the way. But if you follow the steps to the letter and talk with people who have done it in the past, it is possible to get it right.
