The short answer
Replacing the asphalt shingle roof on a typical Gilbert home costs about $9,000–$15,500 in 2026. That’s about 2,200 square feet of roof at $4 to $7 per square foot installed. If your shingles are aging but the roof is still sound, rejuvenation may let you put that bill off for a fraction of the cost.
New roof cost by home size in Gilbert
Prices per square foot are about the same across the Phoenix Valley, so the biggest difference between two Gilbert homes is how much roof each one has. These sizes come from county records for Gilbert’s single-family homes with shingle roofs.
| Home | Roof size | New shingle roof |
|---|---|---|
| Smaller home | 1,900 sq ft | $7,500–$13,500 |
| Typical home | 2,200 sq ft | $9,000–$15,500 |
| Larger home | 2,700 sq ft | $11,000–$19,000 |
Typical = the median home; smaller and larger = the middle half of homes. Roof size is the ground floor plus garage or carport, plus 10% for slope and overhangs. Estimates, not quotes; tear-off of extra layers, decking repairs and permits are extra.
What drives the price in Gilbert
Gilbert’s shingle-roof homes vary more in size than most. The median is about 1,650 sq ft of living space, but one in seven has 2,500 sq ft or more, the highest share of the cities we cover. On a larger home, the cost of a new roof can climb well past the typical range.
Among Gilbert’s single-family homes with shingle roofs:
38%

8%
are two stories, which costs more to re-roof
20%
park under a carport instead of a garage

Do you need a permit to re-roof in Gilbert?
Permit rules for re-roofing differ across the Valley. Mesa, Phoenix and Scottsdale don’t require a permit for a like-for-like shingle replacement, but replacing decking or changing the roof’s structure generally does.
Before work starts, ask the Gilbert building safety office whether your job needs a permit, and ask each roofer whether permit fees are included in the quote.
What else can add to the bill
Tear-off and disposal
Often $1,000 to $3,000 per layer if it isn’t already in the per-square-foot price.
Decking repairs
Commonly $2 to $5 per square foot of plywood replaced. Rot usually isn’t visible until the old shingles come off.
Steep or two-story roofs
A steep pitch can add 25% to 40%, and a second story another 15% to 25%.
Solar panels
Removing and reinstalling panels typically runs $200 to $300 per panel.

Aging roof, still sound? You may not need a new one yet
Rejuvenation is a spray-applied, bio-based treatment that replenishes the oils aging asphalt shingles lose. In Iowa State University testing, the treatment ShingleGuard uses brought shingles from roofs more than 15 years old back to nearly new flexibility. In independent lab testing, untreated shingles shed nearly twice as many granules as treated ones.
For a typical Gilbert roof it runs about $2,200–$2,750 with a roof tune-up included, it’s usually done in a single visit with no tear-off or dumpster, and one treatment supports shingle performance for about 5 to 6 years. It isn’t for every roof: leaks, soft decking or widespread missing shingles mean it’s time to replace, and we’ll tell you so.
