A DIY roof replacement is often a larger project than most homeowners are willing to take on. However, it doesn’t stop the ambitious DIYers.

From small bathroom remodels to completely tearing out and replacing kitchen cabinets and floors. These can all be done with a little bit of research and maybe an experienced friend to help you out. But overall, people can learn pretty quickly how to DIY some projects around their house, but is roofing the same? Can you, or should you, do your own roof replacement?

There is no doubt that roofing is tough work. This is why most homeowners will hire a team of contractors to do it in a matter of days, rather than attempt to DIY. People with experience working with tools and maybe even prior roofing experience may want to DIY their roof replacement. It’s definitely possible, but there are several things to know before you consider doing that. Everything from the tools and materials needed, to taking the proper safety measures to ensure no one gets hurt.

  • Circular saw
  • Extension ladder (long enough to extend 3-feet past roof edge)

Step-by-Step Roof Removal & Replacement

There are a few steps to take before you even start to install your roof. This includes stripping off the old roof completely, plus setting up some tarps to protect your landscaping, as well as renting a dumpster to get rid of your old roof scraps. You may also be able to use a pick-up truck bed and haul it when you’re done. But, depending on the size of your home, you may end up with a dumpster’s worth of junk.

Removing the Old Roof

You will not be able to install your new roof without completely removing all of the prior shingles, flashing, and nails. Any remaining materials, particularly nails, can immediately puncture and damage your new shingles. So, either remove all nails or hammer them down flat against the roof.

  1. Cover any plants and landscaping you want to protect from falling debris using a tarp.
  2. Move any breakable items away from the sides of the house.
  3. Rent a dumpster large enough to hold your old roof’s contents.
  4. Tear off your old shingles and all nails, flashing, underlayment, etc.

Installing the New Roof

  1. Install the drip edge.
  2. Roll out the self-stick underlayment, then pell off the bottom backing.
  3. Cover the underlayment with felt/tar paper, using a staple hammer to adhere it. Place staples no more than 12 inches apart, as it can come loose, or you could trip.
  4. Overlap the tar paper at the roof’s peak and again on the other side.
  5. Roof valleys are sensitive spots susceptible to leaks, so install secure flashing on all valleys.
  6. Also, install flashing on the roof’s peak, and cut the excess off. Use your self-stick underlayment to cover the cut edges.
  7. Install your started shingles on the bottom and work your way up. These will start 1/2 inch overlapping the drip edge and gutters.
  8. Use your roofing nailer (which you can rent) to install your asphalt shingles, row by row, overlapping every single row. Make sure to install them running over the edge of the row, never short. Cut off the excess when you are finished using your hook blade tool.
  9. Install step and dormer flashing around your chimney, skylights, and other structures on the roof.
  10. Install your vent flashing and install your shingles over the flashing for a flush look.
  11. If needed, cut the holes for your attic vents.
  12. Cap the ridge/peak of the roof by installing your shingles perpendicular to the shingles on each side.
  13. Lastly, seal all of your exposed nails and edges with your sealant.
  14. Clean up the roof and safely get down.

Pros & Cons of DIY Roofing

Pro – If you’re on a tight budget, you can save quite a bit of money. Labor is what is so costly, so purchasing just the materials and tools can mean saving a lot of money overall.

Con – Without an expert roofer, you can end up making mistakes or poorly install the roof, ending up costing you even more money, later on, to repair or replace your roof sooner than later.

Pro – You can work on your own timeline. You won’t have to worry about finding the time to have contractors come to your home and be inconvenienced.

Con – You will probably take much longer to install your roof, especially if you work M-F and find yourself only available on weekends to work.

Pro – You will take pride in accomplishing such a huge home project on your own. Homeowners love the feeling of taking on and successfully completing another home project.

Con – Large projects like this can be very stressful and cause arguments with family or friends helping you get the job done.
