Short answer: for a straightforward shingle replacement in unincorporated Paulding County, no. Paulding County’s Building & Permitting FAQ states that if no structural work is performed, roofing and siding work such as replacing shingles may be done without a permit. If structural work is involved — replacing sheathing, rafters, trusses or studs — a permit is required.

That is not the answer everywhere in metro Atlanta, and the variation is larger than most people expect. Cherokee County also exempts shingle replacement. The City of Smyrna explicitly requires a permit for roof replacements, and Marietta and Kennesaw require one for any repair or alteration of a structure. Inside a city, the city is your permitting authority, not the county.

Most homeowners never think about this, because a legitimate roofing contractor pulls the permit for you and you never see the paperwork. But it matters more than people realize, and the homeowners who get burned are usually the ones who hired someone who skipped it.

When a permit is required

The line is generally drawn at the scope of work, not the dollar amount. As a rule of thumb across Georgia jurisdictions:

• Shingle-only tear-off and replacement, unincorporated Paulding. No permit, per the county’s published FAQ.
• Any structural work — sheathing, rafters, trusses, studs. Permit required. This is the one that catches people, because rotten decking is often only discovered after tear-off has started.
• Inside a Georgia city. Ask the city. Smyrna, Marietta and Kennesaw all require a permit for work Paulding County would not.
• Small repairs, a few shingles, a flashing fix. No permit.

Requirements genuinely differ between Paulding, Cobb, Douglas, Cherokee, Bartow and the cities inside them, and they change. We checked each one and published what they say: roofing permits in metro Atlanta, county by county, with fees, formulas, phone numbers and the date each was verified.

Why homeowners should care

It is easy to see the permit as bureaucracy that slows the job down. Here is what it actually buys you.

An inspection you did not pay extra for

A permitted job gets looked at by a county inspector. That is a second set of eyes confirming the decking is sound, the nailing pattern is right, and the flashing was done properly. You get that for the cost of the permit, and it is the cheapest quality control available to you.

It protects the sale of your house

This is where unpermitted work usually surfaces. During a real estate transaction, a buyer’s agent or attorney can pull permit history. An unpermitted roof can delay closing, force a price concession, or require you to open the work back up for retroactive inspection at your expense.

Your insurance may depend on it

If a roof fails and the work was never permitted, an insurer has grounds to question the claim. You do not want to discover that after a storm.

Your warranty may depend on it too

Manufacturer warranties on shingles generally assume the roof was installed to code. Unpermitted, uninspected work gives a manufacturer an easy reason to deny coverage.

Who is supposed to pull it

Your contractor. On a licensed job, the roofing company pulls the permit under its own license and its name goes on it. That matters, because the entity on the permit is the entity on the hook.

Be careful if a contractor asks you to pull the permit yourself as the homeowner. Georgia allows homeowner permits in some situations, but when a contractor requests it, it usually means one of two things: they are not licensed in that jurisdiction, or they want liability sitting with you instead of them. Either is a reason to get another quote.

What it costs and how long it takes

Residential roofing permits in metro Atlanta counties are typically a modest flat fee or a small percentage of job value, normally a minor line item against the cost of a roof. Most are issued within a few business days, and many jurisdictions now handle it online.

It is not the thing that holds up your project. Material availability and weather are.

Storm season is when this gets skipped

After a hailstorm, out-of-state crews arrive in metro Atlanta in numbers. Some are legitimate. Many are not licensed in Paulding County or anywhere in Georgia, and permits are the first thing they skip, because pulling one requires a license they do not have.

The roof gets installed in a day, the crew leaves the state, and two years later you find out the work was never inspected, usually when you try to sell or when it leaks and nobody answers the phone.

Questions worth asking before you sign

• Are you pulling the permit, and is it under your license?
• What is your Georgia license number?
• Are you licensed and insured specifically in this county?
• Who meets the inspector, and what happens if it fails inspection?
• Can I see the permit once it is issued?

A contractor who does this properly will answer all five without hesitating. Hesitation is the answer.

What if my roof was already done without one?

It is fixable, but it is easier to handle now than during a closing. A licensed contractor can usually apply for a retroactive permit and have the work inspected. If it passes, you have clean records. If it does not, you find out what needs correcting while you still have time.

The worst version of this is discovering it three days before you are supposed to sell the house.

If your roof has dark streaks running down from the ridge, you are looking at algae. Not dirt, not soot, not “the shingles wearing out.” A living organism called Gloeocapsa magma, and metro Atlanta is close to ideal habitat for it.

Homeowners in Dallas, Hiram, Powder Springs and across Paulding County ask about this constantly, usually with the same two questions: is it hurting my roof, and do I need a new one? Here are the honest answers.

What the black streaks actually are

Those streaks are colonies of blue-green algae. The spores travel by wind and land on your roof, and where conditions suit them, they multiply and spread. They feed partly on the limestone filler used in asphalt shingles, which is why you see it on shingle roofs and almost never on metal.

The streaking runs downward because gravity carries the spores down the slope with every rain. That is also why the stains usually start near the ridge and work their way toward the gutter.

Why Georgia roofs get it so badly

Algae needs warmth, humidity and shade. Our summers deliver all three for months at a stretch. A roof in metro Atlanta can sit above 70 percent humidity for weeks, and the tree cover most Paulding County neighborhoods enjoy keeps sections of roof damp long after the rain stops.

That is why you often see one side of a roof streaked and the other side clean. North-facing slopes get less direct sun, stay wet longer, and grow algae first. If your north slope is dark and your south slope looks fine, that is the reason, and it is completely normal.

Is it damaging your roof?

Mostly, no. This is the part that surprises people.

Algae itself is a cosmetic problem. It is not eating through your shingles, it is not causing leaks, and a roof covered in streaks can have a decade of life left. We inspect roofs every week that look terrible from the street and are structurally fine.

There are two real costs worth knowing about. Dark streaks absorb more heat than clean shingles, which can nudge your cooling bill up slightly in summer. And algae holds moisture against the roof surface, which over many years can accelerate normal aging. Neither is an emergency.

What algae is often confused with

Moss

Moss is the one to take seriously. Algae lies flat and stains. Moss grows up, holds water like a sponge, and can lift shingle edges, which lets water get underneath. If you can see green fuzzy clumps with visible height, that is moss and it needs attention.

Granule loss

Shingles shed their protective granules as they age, exposing the darker asphalt beneath. That looks like dark patches too, but it is a genuine aging signal rather than a cosmetic one. The tell is location: granule loss shows as irregular bald patches, while algae runs in vertical streaks.

How to get rid of it safely

The single most important thing: never pressure wash an asphalt shingle roof. High pressure strips the granules that protect the shingle from UV, and it will take years off your roof in an afternoon. If a company offers to pressure wash your shingles, that tells you something about the company.

The accepted method is a low-pressure application of a cleaning solution, left to dwell, then rinsed gently. Done correctly, the roof is not scrubbed at all. The chemistry does the work.

Whoever does it should be protecting your landscaping. Solutions that kill algae also kill shrubs, so plants need to be wet down before and rinsed after.

How to keep it from coming back

• Trim back overhanging limbs. More sun on the roof means less time damp, which means slower growth. Highest-value thing you can do.
• Keep gutters clear. Backed-up gutters keep the lower courses of shingle wet.
• Consider zinc or copper strips. Installed near the ridge, they release trace metal ions with each rain that inhibit growth on the slope below.
• Choose algae-resistant shingles at replacement. Most manufacturers now offer shingles with copper granules mixed in, usually with a 10 to 25 year algae warranty.

When streaks do mean you need a roofer

Algae by itself is not a reason to call anyone. But get the roof looked at if you also see any of these:

• Shingles that are curling, cupping or missing
• Granules collecting in your gutters or at the bottom of downspouts
• Green growth with visible height, meaning moss rather than algae
• Any staining on interior ceilings or in the attic
• A roof past roughly 15 years old, where streaks may be masking real wear

That last one matters. Heavy streaking on an older roof can hide the granule loss and cracking underneath. The algae is not the problem, but it can stop you noticing the problem.

The straight answer

If your only complaint is that your roof looks dirty, you probably need a cleaning, not a roofer, and certainly not a replacement. Anyone who looks at black streaks and immediately quotes a full tear-off is selling, not diagnosing.

We will come out and tell you which one you are dealing with. The inspection is free, we photograph every slope, and you keep the written report whether or not you ever hire us. About half the roofs we look at need a repair rather than a replacement, and we would rather tell you that than sell you something you do not need.

Call or text (404) 780-3246 and we will take a look.
