Sun City 85351 by the numbers

Del Webb opened Sun City on January 1, 1960, and built it out over the next 18 years. The 85351 ZIP code takes in everything south of Bell Road. Census figures for 85351 show about 36 percent of homes were built in the 1960s and 53 percent in the 1970s, with almost nothing built since. The median year built is 1972. About 60 percent of homes are detached single-family houses and about 28 percent are single-family attached, such as duplexes and patio homes, with condo and co-op buildings making up much of the rest.

So a typical 85351 roof sits on a house that's at least 47 years old and has been reroofed at least once, often more. Many homes combine a low-pitched main roof with flat or near-flat sections over carports, patios and Arizona rooms added later. Shingle, built-up, rolled roofing, foam and some tile all show up, sometimes on the same house.

The history behind a Sun City roof matters more than the original plans. Before quoting, we want to know how many layers are up there, what the last reroof covered, and whether the flat sections were redone at the same time as the pitched ones.

What Sun City's deed restrictions say about roofs

Sun City has no city government and no single mandatory HOA. Each single-family lot carries deed restrictions (CC&Rs), restated in 1998, and the Sun City Home Owners Association enforces them. RCSC, the Recreation Centers of Sun City, runs the recreation facilities. It's not the body that reviews roofs.

We read the single-family CC&Rs as SCHOA posts them. They don't specify roof materials or colors. The parts that matter for a roof are about upkeep:

• Every building must be kept in good condition and repair, and adequately painted and finished.
• A damaged building must be repaired or rebuilt promptly, or demolished.
• Construction equipment is allowed during work but must be removed as soon as it's done.
• If an owner doesn't fix a condition after written notice, the association can have it fixed after 30 days and charge the owner.
• Some existing conditions are grandfathered only until the home is sold. Anything out of compliance must be brought into compliance before title transfers.

Condos, townhouses and co-ops have their own documents, and the association often owns the roof. Some areas, such as Viewpoint Lake and Dawn Lake, have separate deed restrictions. If you're unsure which rules apply, call SCHOA at (623) 974-4718 before you plan a visible change.

Rooftop coolers and AC units

Many Sun City homes have an evaporative cooler or a packaged AC unit sitting on the roof, often on a low-slope section. They're a common leak source on older Valley homes. The curb or stand the unit sits on, the roof around it and the duct opening all have to stay sealed, and a cooler adds water and constant vibration.

On a reroof, the unit has to be lifted so the roofing can run properly under and around it. Arizona's roofing license rules let a roofing contractor lift HVAC equipment for that purpose. If the ductwork has to be modified to fit the new roof, that part must be done by a licensed HVAC contractor, so we coordinate with one when needed.

A reroof is also a good time to ask whether you still need the unit on the roof at all. An old cooler you no longer use can be removed and the opening framed and roofed over, which eliminates a leak point for good.

Choosing a roof for flat and low-slope sections

Low-slope areas wear out first on most Sun City homes, because water sits longer and the sun bakes the surface all day. The main choices:

• Foam (SPF): sprayed in one seamless layer, then coated. It adds insulation, sheds water well when sloped to drain, and holds up as long as the coating is renewed every several years. New foam typically runs about $5.00 to $8.00 per square foot; recoating sound foam about $2.00 to $3.75.
• TPO membrane: a white single-ply sheet with heat-welded seams. It reflects heat well and runs about $5.50 to $9.00 per square foot.
• Built-up or rolled roofing: the traditional option on many original Sun City flat sections. It can be a good match where the rest of the roof uses the same system, and it needs regular inspection of seams and edges in our sun.

On any low-slope section, drainage matters as much as material. If water ponds for days after a storm, we rebuild the slope toward the drains or scuppers as part of the job. And if the existing roof has more than one layer, it comes off so we can inspect and repair the deck before anything new goes down.

Maricopa County permits for Sun City

Because Sun City is unincorporated, Maricopa County handles building permits. The County exempts a roof replacement or re-roof with the same type of material from a permit. Shingle back to shingle, foam back to foam, or relaying tile over new underlayment generally fits.

Changing material types, such as replacing a built-up section with foam or shingles with tile, can require a County permit, as can structural repairs to rafters or decking found during the job. Tile is much heavier than shingle, so that switch also needs a check of whether the framing can carry the weight. We confirm the County requirement before work starts.

The County has scheduled adoption of the 2024 International Codes, with an effective date of November 20, 2026, and plans to keep the same-material reroof exemption. We'll confirm the current rule when we quote.

After a storm: protecting yourself from door knockers

Monsoon storms between June 15 and September 30 often bring people knocking on doors in older neighborhoods, offering roof inspections. Some are legitimate; some aren't. A few protections under Arizona law are worth knowing:

• Any roofer working on your home must hold an Arizona Registrar of Contractors license. You can look up any license number on the ROC website. Ours is ROC #358508, class CR-42.
• For a sale made at your home, Arizona law generally gives you until midnight of the third business day after signing to cancel.
• For storm-damage roof contracts in an area an insurer has designated as a catastrophic storm area, the contract must say you can cancel within four business days of signing, and within 72 hours after your insurer denies the claim.
• On an insurance claim, Arizona law bars a contractor from advertising, promising or paying your deductible, or rebating it to you. Treat that offer as a red flag.

If your roof is damaged, document it, cover openings to prevent more damage, read your policy, and talk to your insurer. We can photograph the damage and give you a written report. The insurer alone decides what a policy covers.

For costs, typical ranges are $300 to $5,000 for repairs, about $8,000 to $15,000 for shingle replacement and about $4,000 to $18,000 for foam, depending on size, pitch, access and deck condition.
