What roofing costs in Alpharetta

Three houses

Most of Alpharetta falls into one of these. Find yours.

The Downtown ranch. A 1,800–2,200 sq ft single-story off Milton Avenue or in the older streets near Wills Park, simple gable, 22–26 squares, walkable pitch. Cheapest roof in the city to replace: $10,000–$15,500 in architectural shingle.

The Windward two-story. The 3,000–3,500 sq ft brick or stucco traditional that fills Windward, Glen Abbey, Medlock Bridge and the Kimball Bridge subdivisions. Hip roof, 10/12 pitch, four valleys, a chimney, a couple of dormers, 35–45 squares. This is the house most local prices cluster around: $16,000–$32,000 in architectural shingle.

The Milton estate. 4,500–6,500 sq ft on Birmingham Highway, in White Columns or in Country Club of the South. 55–80 squares, 12/12 in places, two or three chimneys, copper accents from the original build. $26,000–$56,000 in architectural and considerably more in a designer line.

Typical ranges, not a quote.

The per-square rate behind the table is $450–$800 for architectural shingle with tear-off, synthetic underlayment, membrane, new flashing, ridge vent and cleanup. Alpharetta sits in the upper half of that range more often than not, because the roofs are steeper and more cut-up than the houses they cover suggest. Three-tab is roughly 15% less, and few roofers here install it; the HOA usually will not have it anyway. Set against the metro Atlanta average, the difference is mostly pitch and complexity, not the address.

Repairs

• Pipe boot$250–$450
• Wind-lifted shingles$300–$800
• Ridge cap or ridge vent$350–$900
• Skylight flashing kit$400–$900
• Kick-out or dormer flashing$450–$1,100
• Valley re-lay$500–$1,200
• Chimney flashing$600–$1,500
• Emergency tarp$300–$700

Typical ranges, not a quote.

A single visit is usually $300–$1,500. Once a repair on an 18-plus-year-old roof passes about $2,500, ask for the replacement numbers next to it so you can decide with both in front of you. The post on repair versus replacement works through that call.

What pushes a quote up

• Pitch above 8/12. Staging, harnesses, slower crews. Most of the city qualifies. Add 10–20%.
• Cut-up roofs. Each valley, dormer, skylight and chimney is flashing work. A Country Club of the South hip roof with three chimneys costs more per square than a Downtown gable and should.
• Rotten decking. $90–$150 a sheet. A valley that leaked for five years can hide six or eight sheets. Expect an allowance in the quote, and ask to see every sheet replaced.
• Shingle line. Heavyweight architectural adds $50–$120 per square; luxury profiles $150–$300 plus labor.
• Metal accents. A standing-seam porch or bay during the replacement adds $2,500–$7,000; copper more.
• Access. Pools, tight side yards, gravel drives on Milton acreage, gated communities with delivery windows.
• The calendar. Prices tend to hold year-round, but after a big storm the wait for a non-emergency replacement can stretch to several weeks.

Comparing quotes

When one roof estimate, Alpharetta or anywhere else, undercuts the others by thousands, it has usually left something out — a big gap usually means a different scope. Check that each quote names, in writing: full tear-off; synthetic underlayment; where the ice-and-water membrane goes; the shingle line and its wind class; six nails per shingle; a per-sheet decking price; new flashing including stucco kick-outs; ridge vent; who handles the HOA submittal and any permit; and the manufacturer and workmanship warranties in years. If a line is missing, ask. If the answer is vague, you have your answer. The post on how to read a roofing quote goes line by line.

Costs that aren't on the roofing quote

A roof price covers the roof. A few related costs land on the same month's budget, and it helps to know them up front.

• Drywall and paint inside. If a leak ran for a while, the ceiling below needs patching after the roof is fixed. That's a painter or handyman, not the roofer.
• Gutters and fascia. Rotted fascia board found at tear-off is often priced separately. So is a new gutter run if the old one is bent.
• Tree work. Limbs over the roof should come back before a new roof goes on. An arborist prices that.
• Attic insulation. If the attic is under-insulated or soaked from a leak, topping it up is a separate job, but easiest right after the roof.
• Skylights. Replacing an old unit during the re-roof adds $800–$1,800 per unit to the roof job.

How to budget for a roof you know is coming

If the roof is 15 to 18 years old, you have time to plan. Get a written replacement price now, even if you won't use it for two years; it gives you a real number to save toward. Do the small repairs that keep it dry in the meantime, and keep the invoices. Pick a season: October–November and March–April are the easiest to schedule. And get the HOA approval in hand before the roof becomes urgent, so a committee meeting doesn't hold up a job you need.

Paying

Insurance generally covers sudden wind, hail and tree damage, not age — check your policy. Financing offered by roofers is normally a manufacturer program at 12 to 60 months. A home equity line is often the cheaper way to fund a $25,000 roof. Ask for both sets of numbers and compare them yourself.
