How Much Does a Shingle Roof Installation Cost in Phoenix, AZ?


Replacing a shingle roof in Phoenix varies in cost, the two key factors which affect price are size and difficulty.

Size is self-explanatory: the larger the surface, the more materials and time need. The other factor that affects price is the level of difficultly; this is not as clear cut. Below I’ll breakdown the elements which increase a project’s difficulty.

But first, let’s talk about what you’re most interested in: how much?

Here at Estrella Roofing our average cost of a shingle re-roofing project is $8,500.

Now that you have a ballpark cost, let’s look at the variables which dictate the difference between a 7,000 and $12,000 re-roofing shingle installation.

Factors that affect price

Size of your roof

Materials are priced by square footage. As a result most quotes are based on the sq. ft. of your home’s roof (not to be mistaken for your home’s sq. ft.).

The measurement term you will hear when obtaining a quote is “roofing square”. A roofing square is what contractors use when deciding how much material (tiles, underlayment etc.) will be needed. The term simply refers to a 10’ x 10’ area, which is equal to 100 sq ft.

  • One Roofing Square = 10’ x 10’ area or 100 square feet.
  • Therefore, if your roof is 2,000 square feet it is equal to 20 roofing squares.

In Phoenix, on average, you can expect to pay about $4.00 per square foot for all project materials. This includes shingles, some type of roofing cement, nails and underlayment. Keep in mind, not all roofing materials are created equal. It can affect the average square footage price of $4.00 mentioned above.

Level of difficulty

Pitch/Slope

roof slope pitchThe roof’s pitch is the second factor that affects cost, after materials. You can expect to pay more for a roof with a pitch greater than 6:12; this is considered a “non-walkable” pitch. As a result, it requires additional preparation to ensure safety and proper completion.

The roof’s pitch also can affect the amount of underlayment needed. An industry standard says that a roof between 2:12 and 4:12 pitch should have two layers of felt or underlayment installed. Compare that to a flat roof which has a pitch of about ½ :2:12 and 2:12 may require less to meet fire rating regulations.

Removal/Disposal

Another factor which varies on a per project basis, is the removal and disposal of the current roof. This is calculated by the time needed to tear off and haul-away the old roof. Weight is the key factor in the equation: the heavier the weight, the longer it takes to remove, the more it costs to dispose of.

Access

How hard is it to get to your roof? Will it be difficult to dispose of your old roof or get the new materials on top of your roof? If additional equipment will be needed you can expect labor cost to be affected.

Repairs

During re-roofing projects it is common to have other issues repaired. The common problem areas are found in locations where something is cut into the roof: skylights, chimneys, vents etc. This is also a good time to evaluate the condition of the wood. A contractor should bring any repairs to your attention as part of the estimate.You  also can also check about wall deck installation

 

Buyer Beware Tips

A warranty is also a factor that can affect price. A two year installation warranty is offered by most roofing companies.

You can expect a 10 – 20 year manufacture warranty on materials. With that being said, if the roof is not installed to the satisfaction of the manufacture specification, the manufacture warranty will be void. It is not uncommon to inspect a roof and see that the manufacture warranty has been compromised due to installation.

More on what you need to know before hiring a roofing contractor.

Always be sure that the company or contractor you hire is bonded, insured, and that they provide an installation warranty.
