Roof life in the desert is set by the sun. Tile itself can last for generations, but the underlayment beneath it does not. Shingles age faster here than in mild climates.
How long does a roof last?
It depends on the material. These are the national lifespans HomeGuide publishes.
| Material | Published lifespan |
|---|---|
| 3-tab asphalt shingles | 15 to 20 years |
| Architectural shingles | 20 to 30 years |
| Concrete tile | 30 to 50+ years |
| Clay tile | 50 to 100+ years |
| Underlayment under tile | 20 to 30 years |
| Metal | 30 to 80+ years |
| TPO | 10 to 25 years |
| Built-up | 20 to 30 years |
These are not promises for Scottsdale. Heat and ultraviolet light are harder on asphalt and underlayment than a mild climate is, so do not count on the top of a range without regular inspections.
How long does a tile roof last in Arizona?
The tile lasts far longer than what is under it. Concrete tile is published at 30 to 50 years or more and clay at 50 to 100 or more, while the underlayment below is published at 20 to 30 years. So a tile roof usually needs its underlayment replaced at least once in its life, with the same tile relaid on top. That is the most common large roofing job in Scottsdale.
How long does the underlayment last under tile, and can I reuse my tiles?
Underlayment under tile is published at 20 to 30 years, a national HomeGuide figure, and desert heat can shorten that. Yes, the tiles can usually be reused. The crew lifts and stacks them, replaces the underlayment, flashing and any bad wood, then relays the same tile. Some always break in handling, so the quote should include an allowance for replacements. Reuse is harder when the tile is a discontinued profile, is already cracking widely, or is a lightweight type that does not survive being walked on.
How long does a roof replacement take?
A full roof replacement usually takes 1 to 3 days, depending on size and weather. Large tile roofs, where every tile is lifted, stacked and relaid, and big flat commercial roofs take longer. Many repairs are completed in one visit. We give you the expected length in the written quote.
Can a roof be finished in one day?
Sometimes. A small, simple shingle roof with one layer to remove and sound decking can be finished in one day by a full crew. A foam re-coat on a modest roof can be too. Tile lift and relay jobs are not one day jobs, because of the handling. Speed matters less than leaving the roof watertight each evening. Ask what gets done on day one and how the roof is left overnight.
What is the best time of year to replace a roof?
The best time of year in Scottsdale is autumn through spring, roughly October to May. The weather is dry and mild, crews can work full days, and materials are easier to handle. Those months are also the busiest. Summer work is possible but slower. If your roof needs to be sound before the monsoon, book in spring.
Can a roof be replaced in winter or in extreme heat?
Yes to both. Winter here is mild, with no snow to work around, and it is prime roofing season. In summer heat, crews start at first light and stop by early afternoon, so a job takes more days. Shingles get soft and scuff easily when hot, and coatings and adhesives have temperature limits set by their makers. We schedule around those limits.
What happens if it rains during the job?
If it rains during the job, the roof is covered and work stops until it dries. We watch the forecast and open only as much roof as can be made watertight the same day. That matters most from mid June through September, when a monsoon storm can build in an afternoon. Weather can move the schedule.
Do I need to be home, and how loud is it?
You do not need to be home for the whole job, but we need a way to reach you and access to the yard and power. It is loud. Tear-off, tile handling and nail guns make noise and vibration through the house. Take pictures off walls under the work area, and plan for pets, small children and anyone working from home. We walk the finished roof with you at the end.
How do I get my house and yard ready?
- Move cars out of the garage and driveway before the crew arrives
- Clear patio furniture, grills and pots from around the house
- Tell us about pool equipment, irrigation lines and landscape lighting near the walls
- Cover or move items in the attic or garage below the work
- Unlock gates and tell us about any alarm or gate codes
- Let the neighbours and your HOA know the dates
How long do I wait for a start date?
It depends on the season and the material. We give you a start date with the written quote. Waits are longer in the cool months and after a big storm, when many roofs need work at once. Special-order tile or a colour your HOA must approve can add time. A leaking roof is made watertight first while the full job waits its turn.
Should I replace the roof before winter or before the monsoon?
In Scottsdale the deadline that matters is before the monsoon, not before winter. Winter here is mild and dry and does a roof no harm. The storms that find weak roofs arrive from mid June through September, with wind, hard rain and the odd hailstorm. If an inspection shows the roof will not get through another summer, have it replaced or made sound by late spring. If the report says it has years left, there is no reason to rush before either season.
How long can the roof be left exposed, and what if the job drags on under tarps?
A roof should be left exposed for as short a time as possible, and each day should end with it watertight. Underlayment makers set a limit on how long their product may sit uncovered in the sun, and Scottsdale's ultraviolet light is hard on it, so ask which product is used and its limit. Tarps are short-term cover. Their published life is 60 to 90 days, and wind works them loose well before that. If a job stalls, ask in writing for the reason, a new finish date and who checks the tarps after each storm. Your contract should state an estimated completion date.
How long before new shingles settle and lie flat?
New shingles settle and lie flat once the sun has warmed them enough for the seal strips to bond. In Scottsdale that usually takes only days for most of the year. Shingles come out of the bundle slightly bowed, so small ripples on day one are normal. In cooler winter weeks it can take longer. Lumps that remain after a few warm weeks are something else, such as a raised nail, a buckled underlayment or an uneven deck, and the roofer should look at them.
