You can’t just go to the store and buy a new roof. It takes time, effort (not to mention money), materials needed for replacement roofs like shingles or tiles; then there are all those pesky lichen patches that need removing first before they start causing problems on their own accord- not exactly something you want happening while your house is under construction.


When it comes to choosing a new roof for your home, you want one that will last and protect you from the elements. That’s why we’re going over 4 different types of roofs so understand what material might work best in each case.

Cut Roof Replacement Cost by 20%

The most common type of roof you’ll see on homes today is the asphalt shingle. It’s made primarily out of these little black tiles with other pieces attached at different angles to create your perfect home, and it also happens to be one-of-the cheapest options available.

1 Story vs 2 Story House Approximate Roof Cost

With a standard roof on a single-family home, you can expect to pay around $3.55 per square foot for the house’s components such as architectural shingles or underlayment. You can expect to pay around $4.58 per square foot for a two-story house with complexity and good accessibility, which includes using all of the manufacturer’s roofing components.

Estimating Metal Roof Replacement Costs

These screw-down panels provide durable, long-lasting roofs that are guaranteed not to expand or contract. They can withstand high winds without worrying about popping off like other types of metal roofing do. The standing seam metal roof system is a series of panels that are locked together at the seams or seamed mechanically, allowing them to expand and contract freely when heated up. The estimated cost for metal roofs will run you somewhere around $4.31 per square foot.

Evaluating Roofing Cost

The cost to replace your roof may seem like an easy decision, but there are many factors that affect the final price. Items like nails and labor can be included in or out depending on what you want to be done with them; ventilation is also important if it isn’t already installed when replacing shingles onto new pipes.  The cost to replace a roof will vary depending on many factors, including but not limited to the roof pitch.

The average range on the east coast is between $5,300 and $9,223, and on the West Coast floats around $7743-$12,223. Many companies charge around 2-5 cents per square foot for labor plus materials which equals out about the perfect price point when you consider how much space an entire 1500 sq ft tiled surface takes up.

Calculate the Cost to Reshingle Your Roof

When it comes to re-shingling a roof, the national average cost is around $7420. This can vary drastically depending on factors like size and location as well as other things that affect how much your repair will be in terms of materials used or the number of shingles needed for different types of roofs- all these make up an individual estimate per job which varies greatly too. If you’re looking for more minor repairs instead then fixing everything altogether could save plenty when compared to hiring someone who does complete jobs like this one day but doesn’t have any experience doing just what’s necessary at least initially until they learn about potential problems.
