Straight answers

The questions we get every single week.

Arizona roofing has its own physics, and most of the confusion comes from advice written for climates that have a winter. Here is how it actually works here.

General roofing questions

How much does a new roof cost in Phoenix?

It depends on the roof system, the size and pitch, how much decking has to be replaced, and how many penetrations and transitions are involved — which is why nobody can give you a real number over the phone. We walk the roof, photograph it, and put a written estimate in front of you.

My tile looks fine. Why would I need a new roof?

Because tile is a rain shield, not the waterproofing layer. The underlayment beneath it is what keeps water out, and Arizona heat and UV age that layer far faster than the tile above it. Perfect-looking tile over failed underlayment is the most common roof condition in the Valley.

How long does a roof last in Arizona?

Shorter than the number on the packaging, because those ratings assume a milder climate. Tile itself lasts decades, but the underlayment under it typically runs roughly 15–25 years depending on the system. Asphalt shingle life is shortened by deck heat and UV. Standing seam metal is the longest-lived residential option here.

Should I repair or replace?

If the failure is local — one valley, a few tiles, a bad pipe boot — repair it. If the underlayment is brittle across every slope, repairs are money spent twice. We show you photos of your own roof so you can see which situation you are in rather than take our word for it.

Can you re-use my existing tile?

Usually, yes. Concrete and clay tile routinely outlast two or three underlayments. On a lift-and-re-lay we stack your tile, replace everything underneath, and re-set the same tile — so you keep the roofline and the colour you already have approved.

What causes most roof leaks in Phoenix?

Penetrations, not the field of the roof. UV-cracked rubber pipe-jack boots are the single most common culprit, followed by failed valley metal, parapet and wall flashing, ridge and hip mortar that has opened up, and anything a later trade bolted to the roof.

When is monsoon season and what does it do to roofs?

Officially June 15 through September 30. The damage comes from microburst outflow winds — fifty or sixty miles an hour with almost no warning — driving heavy rain sideways under tile and under lifted shingle edges. It is why a roof can be fine in June and open in July.

Do you do flat roofs and foam?

Yes. Modified bitumen, cap sheet and sprayed polyurethane foam, plus re-coats. A lot of Valley homes have a low-slope section behind the tile — over a patio, an addition, or a whole mid-century house — and that is where a good number of leaks start.

Is a metal roof a good idea in Arizona?

It is one of the best. Standing seam sheds monsoon rain fast, handles wind-driven debris without cracking, reflects a serious share of the solar load off the deck, and has no exposed fasteners to back out under UV. It costs more up front and it is often the last roof the house needs.

Do you offer free estimates?

Yes. Call or text (602) 794-5224 and we will come out, walk the roof, and give you photos and a written estimate.

How soon can you get out here?

Call and ask — it depends on the week and on whether you have active water coming in. Storm damage and active leaks get prioritized over planned work.

Do you work on commercial buildings?

Yes. Low-slope membrane, coatings and standing seam metal on commercial and light-industrial roofs, alongside our residential work.

What areas do you serve?

We are based at 3336 W Missouri Ave, Phoenix, AZ 85017 and work the Phoenix metro — Phoenix, Glendale, Scottsdale, Mesa, Tempe, Chandler, Gilbert, Peoria, Surprise, Avondale, Goodyear, Buckeye.

Can I send you photos instead of scheduling a visit?

Send them over WhatsApp to (602) 794-5224. Photos are a good way to start, but anything that matters still needs someone on the roof — you cannot assess underlayment from the ground.

Question not answered here?

Call or text (602) 794-5224. If it is a question worth asking, it is worth a straight answer, and we would rather give you one than have you guess.

Still not sure what your roof needs?

That is normal, and it is not your job to know. Call or text (602) 794-5224 and describe what you are seeing — we will tell you which of these it actually is.
