An 800 square-foot roof will cost the average homeowner between $3400 -$5100. Finding the right replacement for your roof requires considering the cost. Here is how much it costs to replace an 800 square foot roof.

The job isn’t as expensive as you might think. If you live in a small home, you won’t have to dish too much money out of your bank account to cover the project. We’ve put together this guide to help you figure out the average roof replacement cost for an 800 sq ft roof based on material.

800 sq ft Roof Replacement Cost: Breaking It Down

It’s difficult to put an accurate price tag on an 800 sq ft roof replacement because there are so many factors that impact the cost. When you’re trying to figure out how much to budget for a roof replacement, the first thing you need to do is figure out what material you’re going to use.

Roofing Cost by Material

The thing that will account for the largest part of your roof replacement cost is the material. The job can jump from affordable to expensive just based on the material alone, so you should spend a lot of time researching your options and finding the best fit for your home.

Keep in mind, the “best fit” isn’t always the cheapest choice. Your roof is your home’s first line of defense against the elements, so it’s worth investing more money in a material that will be able to withstand the weather conditions in your area.

Here’s a closer look at some of the most common roofing materials and their average prices:

  • Asphalt Shingles – $3.50 to $5.00 per square foot
  • Metal – $6.00 to $12.00 per square foot
  • Slate – $9.00 to $16.00 per square foot
  • Tile – $4.00 to $16.00 per square foot
  • Concrete – $12.00 to $18.00 per square foot
  • Wood – $4.50 to $9.00 per square foot

Additionally, these prices are just averages. You may end up paying a bit more (or even a bit less) depending on the specifics of your project.

A Rough Estimate 

So how much would it cost to replace an 800 sq ft roof? We’ve put together a rough estimate to give you a basic idea.

For example, let’s say you chose to replace your roof with asphalt shingles, and let’s say you spend $4.50 per sq ft for the material. For an 800 sq ft roof, you’ll end up paying $3,600 total.

Keep in mind, though, this number just covers the cost of the material. You’ll also have to add in the cost of labor to get an accurate quote.

The Roof Design

Does your roof have steep slopes? Is it surrounded by tall trees? Does it have complex curves or nooks?

These things will make it more difficult for a contractor to replace your roof. They might need to use special tools to help them keep their footing or to fit the material into the right spots.

The easiest and cheapest roof designs are flat.

If you have a flat roof, you can expect the rough estimate above to be fairly accurate to your job. If you have a different design, you might need to add more money to the cost to cover additional expenses.

The Location

Every state has its own price range for roof replacement services. Paying higher than the national average (or lower) is normal depending on where you live.

For example, the average local price to replace an 800 sq ft roof with asphalt shingles in Monterey, California, is between $4.30 and $7.40 per sq ft (for both material and labor). Compare that to the average local price of replacing a roof in Chicago, Illinois. Using the same material, you would have to pay anywhere from $4.90 to $8.40 per sq ft.

While these prices are similar, even an extra dollar can completely change the total price of the job. So when you’re getting a quote for your roof replacement, make sure you consider the local costs, not just the national average.

How Much Does an 800 sq ft Roof Repair Cost?

Again, it’s difficult to come up with an exact number for a repair job. Every repair costs a different amount, depending on what you need to have done, and the material of your roof and the location of your home will play a part, too.

Here’s a closer look at the average prices for common repair jobs to give you a basic idea of what you’d end up spending:

  • Leak – $10 to $120
  • Damaged flashing – $20
  • Cracked shingles (or missing shingles) – $30 (depending on how many new shingles you need)
  • Skylight leaks – $20 to $80
  • Fascia repair – $10 to $30 per 8-foot board
  • Gutter replacement – $4 to $8

Remember, though, these are national averages. You may need to spend more money on the job depending on where you live and the specifics of the repair.
