When’s The Best Time To Have Your Roof Worked on in Arizona

One of the basic tenants of economics says that when supply is high and demand is low—prices are the cheapest. As an informed consumer you should try to plan your roofing needs around this principle. Obviously if your roof leaks in the middle of a monsoon storm then you don’t have much a choice on when to have your roof worked on, but if you have some level of control, try to work around the information detailed below.

According to About.com, Phoenix had the following monthly average rainfall from 1981-2010:

  • 0.91 Inches of Rain: January
  • 0.92 Inches of Rain: February
  • 0.98 Inches of Rain: March
  • 0.27 Inches of Rain: April
  • 0.11 Inches of Rain: May
  • 0.02 Inches of Rain: June
  • 1.05 Inches of Rain: July
  • 1.00 Inches of Rain: August
  • 0.64 Inches of Rain: September
  • 0.58 Inches of Rain: October
  • 0.65 Inches of Rain: November
  • 0.88 Inches of Rain: December

If you look closely you will notice that the month of June has by far the least rainfall followed by May and April.


How does this information translate into a savings for you? Rain and roof work tends to be correlated. When it rains, Phoenix area roofers’ schedules book right up. And when things get busy, it takes more Benjamins to get someone’s attention.

If you wait until the middle of the Phoenix monsoon season to get a quote, here are the top three problems that will result:

  1. Pay More: If you wait another month to get your roof looked at, you will pay upwards of 30% more to get your roof repaired.
  2. Slower Work: If your roof leaks during the first monsoon storm, it could be a few weeks (and storms) later before a company has the time to fix your roof. This obviously puts your home and all its valuables at risk of water and mold damage.
  3. Less Attention: When roofers are busy, they’re unable to give you the attention you deserve. It’s your roof and a hundred other ones, not your roof and ten others. 

How do you know when it’s time to have your AZ roof inspected? 

The frequency with which you should have your roof inspected various by roofing material.

Metal Roofs

Metal roofs should be checked at least once every ten years. If your Arizona metal roof is approaching 30 years old, you should start getting it inspected every five years.

Shingle Roofs

Shingle roof longevity is affected by the quality of the materials originally installed. Typically shingle roofs last around 15-20 years in Phoenix. If your shingle roof is 12 years or older, it’s time to get it inspected.

Tile Roofs

Tile roofs in Arizona last about 20-25 years. The limiting factor is your underlayment – which can cause leaks a good five years early. If you are nearing this window, an inspection is critical.

Foam Roofs

Foam roofs need to be recoated every 5 years. Recoating your foam roof is cheap but it’s an absolute requirement. With regular maintenance (including recoats), your foam roof can last 10+ years.

If you’re noticing these problems occurring with your roofing material, you might need your roof repaired or replaced within the next year:

  1. Cracked or curling shingles. Cracked shingles are brittle and split in two quite easily. This indicates that the asphalt material is pretty much gone. Curling shingles, are shingles that no longer stay flat against the roofing surface.
  2. Bent, rusting, or missing metal material. If you have metal on your roof that is in bad shape, don’t ignore it. We see hundreds of Phoenix homes each year that leak because of ‘small’ problems like these.
  3. Water pooling. If you notice water collect in an area and not leave for many hours, your roof will likely not last nearly as long as it is rated for.
  4. Popcorn looking foam. If your foam roof looks like popcorn and has hundreds of micro abrasions in it, it most likely needs recoated. Foam roofs in Arizona should be recoated every five years, otherwise they may leak.

The longer you wait to have your roof checked, the greater your repair bill from water damage will likely be. Most roofing companies offer free estimates, so if you’re even just remotely concerned about your roof get one done. Most companies will peel back a layer of your roofing material to check on the health of the underlayment beneath.
