GUIDE / SEASONAL
Monsoon wind
rarely breaks
a sound roof.
It finds the weakness that heat spent the previous nine months creating. Which means most monsoon roof damage is decided before the season starts, not during it.
THE USEFUL FRAMING
“A storm is a test, not usually a cause.”
01 / WHEN IT RUNS
June 15 to
September 30.
Those are the National Weather Service dates, fixed rather than weather-dependent. Storms arrive irregularly within that window, often as short violent events in the late afternoon and evening.
WHAT ACTUALLY REACHES A ROOF
Wind-driven rain,
not the
rain itself.
A roof handles vertical rain by design. What monsoon adds is rain arriving nearly horizontally, driven under tile, into laps, and past flashing that would be adequate in ordinary weather.
Add dust, which precedes the rain and blocks drainage, and short intense bursts that overwhelm scuppers and valleys faster than they can clear.
The roofs that suffer are the ones with something already wrong: brittle underlayment, lifted flashing, a valley full of debris, fasteners that have worked loose through years of thermal cycling. The storm exposes it. The heat caused it.
02 / BEFORE THE SEASON
What is worth
doing in
spring.
None of this requires a contractor. All of it is cheaper than the alternative.
01
Clear the valleys and drains.
Debris in valleys and blocked scuppers are the most common avoidable cause of storm-related water entry. On a low-slope roof, blocked drainage turns a rainstorm into standing water.
02
Look at the roof from the ground.
Slipped or cracked tile, curling shingles, anything visibly out of place. Binoculars work. Getting on a roof you are not equipped for is a worse idea than the problem you are checking for.
03
Check the ceilings you ignore.
Garage, closets, the corners of spare rooms. Old stains you have stopped noticing are worth a second look before the season that will test them.
04
Deal with anything you already know about.
The small repair you have been meaning to book is the thing a storm will find. June 1 is a better deadline for it than the first warning.
03 / AFTER A STORM
Document first.
Decide
second.
The period right after a storm is when the worst roofing decisions get made, because urgency and door-knocking arrive together.
01
Photograph before anything is touched.
Date-stamped photographs from the ground, of the roof and of any interior damage. Photograph the location as well as the defect, so it is clear later where each picture was taken.
02
Write down the date and time.
Which storm, when. Obvious at the time, genuinely hard to reconstruct three weeks later when it matters.
03
Be careful with door-knockers.
Not everyone who arrives after a storm is a problem, but the pattern of pressure, same-day signature and a deductible offer is worth recognizing. In Arizona a contractor may not advertise to pay or absorb your deductible.
04
Nobody can promise a claim outcome.
Anyone who tells you before an inspection that insurance will cover this is telling you something they cannot know. Under A.R.S. 32-1158.02 a contractor doing post-storm repair may not assure you the work will be covered.
04 / COMMON QUESTIONS
Common ones.
I lost tiles in a storm. Is that storm damage?
It may be, and it should be documented properly either way. Displaced tile is sometimes a wind event and sometimes fasteners that had already deteriorated. The distinction matters for how the work is handled and it is settled by looking rather than assuming.
Should I get on the roof after a storm?
We would rather you did not. Wet tile is slippery, storm-damaged roofs have unstable areas that are not visible from above, and what you can see from the ground with binoculars is enough to decide whether someone should come out.
How quickly do I need to act?
Quickly on anything letting water in, because interior damage compounds by the day. Not quickly on the decision about who does the work. Those are different clocks and they get conflated deliberately by people knocking on doors.
Is a tarp worth it?
As a temporary measure on an active leak, yes. As a solution, no. A tarp buys days, and it should be treated as a way to stop the damage getting worse while a proper assessment happens rather than as a repair.
Does my roof need checking every year?
After a significant storm, yes, particularly if the roof is past fifteen years. Every year regardless is more than most roofs need. The useful trigger is age plus events rather than the calendar alone.
Storm damage to look at?
Get it documented in writing and in photographs before any decision is made about the roof.
