How to Choose a Shingle Roofing Company Near You That Knows Its Shingles
Choosing a shingle roofing company near you means finding someone who can explain the difference between shingle lines, not just quote a color. Charleston Roofs and Windows walks you through types, wind ratings and colors before you sign anything.
"Our sales person Michael was incredible. He helped me tremendously in picking out the right shingles, windows and doors. And Adam the Project Manager was awesome. He supervised his team from start to finish"
Three Questions to Ask a Shingle Roofer
Which Shingle Brand Are You Certified to Install?
Manufacturers only stand behind their best warranties when a trained contractor installs the full system. A roofer who can't name a certification can't register those warranties.
How Charleston Roofs and Windows Answers
Charleston Roofs and Windows holds Atlas Pro+ Diamond Level status, the top reward tier in the Atlas PRO+ program.
● Earned by Installing, Not Paying
Atlas moves contractors up through Gold, Platinum and Diamond as they install Signature Select systems and shingles with Scotchgard Protector. We're the only Diamond contractor in our service area.
How Do You Keep Algae Streaks Off My Roof?
Plain shingles in a humid coastal climate can streak within a few years. Ask what the shingle has built in to fight it, and how long that protection is designed to last.
How Charleston Roofs and Windows Answers
We install Atlas shingles with Scotchgard Protector, which uses slow-release copper granules to keep the black algae from taking hold.
● Scotchgard Protector
A 3M technology built into the shingle's granules, not a spray-on coating that wears off.
What Wind Rating Will My Shingles Carry?
Wind ratings vary a lot between shingle lines. Three-tab shingles often carry a 60 mph rating, while premium architectural lines can reach 130 to 160 mph when installed to spec.
How Charleston Roofs and Windows Answers
Your estimate names the shingle line and its wind rating. Charleston Roofs and Windows installs the Atlas starter, sealant and nailing pattern each rating depends on.
Architectural vs. 3-Tab vs. Designer Shingles
Asphalt shingles come in three main types: 3-tab (strip) shingles, architectural (laminated) shingles and designer (premium) shingles. Charleston Roofs and Windows installs architectural and designer shingles on almost every Lowcountry home, and here is why.
- Construction One flat layer
- Weight per square About 200 to 240 lbs
- Look Flat, uniform rows
- Typical wind rating 60 to 70 mph
- Lifespan in coastal SC About 12 to 17 years
- Installed cost (2026) About $3.80 to $6.50 per sq ft
- Best for Sheds, outbuildings, matching an old roof
- Construction Two layers laminated together
- Weight per square About 240 to 300 lbs
- Look Dimensional, shadowed
- Typical wind rating 110 to 130 mph
- Lifespan in coastal SC About 20 to 25 years
- Installed cost (2026) About $4.85 to $8.65 per sq ft
- Best for Most homes, best value
- Construction Two or three thick layers
- Weight per square About 350 to 480 lbs
- Look Mimics slate or cedar shake
- Typical wind rating 110 to 130 mph, some Atlas lines higher
- Lifespan in coastal SC About 25 to 40 years
- Installed cost (2026) About $8.00 to $14.00 per sq ft
- Best for High-end homes, curb appeal, top wind and impact ratings
3-Tab Strip Shingles
Strip shingles are a single flat layer with three tabs per piece. They cost the least, but their low wind rating and shorter life make them a poor fit for a full Lowcountry home roof today.
Architectural Shingles
Architectural shingles bond two layers together, giving the roof depth and shadow lines. They're heavier, hold better in wind and last longer than strip shingles for a modest bump in price. Charleston Roofs and Windows installs more of these than anything else.

Designer Shingles
Designer shingles stack thicker layers to mimic slate or hand-split shake. Atlas lines like StormMaster Shake add a UL 2218 Class 4 impact rating, the highest rating given to asphalt shingles.
Atlas Shingles With Scotchgard Protector vs. Black Algae Streaks
Black streaks on a shingle roof are colonies of Gloeocapsa magma, a blue-green algae that thrives in humid air and spreads across damp shingles. Charleston Roofs and Windows installs Atlas shingles with Scotchgard Protector to keep it from taking hold.
Why Lowcountry Roofs Streak
Coastal South Carolina gets around 50 inches of rain a year and stays humid much of the year. That's ideal for algae, and Charleston Roofs and Windows sees it most on these roofs:
- North-facing slopes that stay damp longest after rain or dew.
- Roofs under live oaks and pines where shade keeps the shingles cool and wet.
- Low-slope sections where water and debris sit longer.
- Roofs with clogged gutters that hold moisture at the eaves.
How Scotchgard Protector Works
Scotchgard Protector uses copper-containing granules with a porous 3M ceramic coating. The coating lets copper ions release slowly over time as rain washes across the roof, and the copper keeps algae from establishing on the shingle.
Protection That Works Every Time It Rains
Because the protection lives in the granules, every rain releases a little more copper across the roof. Your Charleston Roofs and Windows inspection manager can also spot early streaking on an older roof during a free inspection.

Shingle Wind Ratings and Hurricane Season
A shingle wind rating is the wind speed a shingle is warranted to resist when it's installed to the manufacturer's instructions. Charleston Roofs and Windows treats the rating as a system, because the starter course, sealant strip and nails do the holding.
What Keeps a Shingle on the Roof
Starter shingles at the edges. Atlas Pro-Cut HP42 starter seals the eaves and rakes where wind uplift starts.
The right nail placement. Atlas HP42 shingles use a wide Sweet Spot nailing area so nails land where they hold.
A double sealant line. Atlas FASTAC sealant bonds each course to the one below once the sun warms the roof.
Sealed hips and ridges. Matching Atlas hip and ridge caps finish the peaks where wind hits hardest.
Upgrading Beyond the Shingle
For homes that want more than a higher wind rating, Charleston Roofs and Windows can build your shingle roof to the FORTIFIED standard, with a sealed deck and reinforced edges. A metal roof is another option for exposed island lots.
"We had some missing shingle damage after hurricane Ian came through and Kim was able to schedule an appointment with Eric Chessnut rather quickly. Eric came out to assess the damage. He was very knowledgeable, honest and pleasant to work with."
Choosing a Shingle Color That Works in Lowcountry Sun
Shingle color changes your home's curb appeal more than any other roof choice, and it also affects how hot the roof gets. Your Charleston Roofs and Windows inspection manager helps you narrow the choices so you see colors against your home, not just on a phone screen.
Tips for Picking Your Color
-
Look at samples outside, at different times of day. Granule colors shift between morning and afternoon light.
-
Match the fixed colors. Brick, stone and window trim aren't changing, so pick a shingle that works with them.
-
Lighter shades reflect more heat. Atlas Pinnacle Sun uses 3M cooling granules made to reflect the sun.
-
Check HOA rules first. Many neighborhoods limit roof colors.
-
Step back to the street. Judge the color the way neighbors will see it, across the whole roof, not from one shingle in your hand.
Pinnacle Pristine Colors
Atlas offers Pinnacle Pristine in colors including Weathered Wood, Black Shadow, Coastal Granite, Pewter, Oyster Shell, Tan Mist, Hearthstone, Summer Storm, Copper Canyon and Woodland Green.

How Long Shingles Last in the Lowcountry and When to Repair or Replace
A shingle roof's lifespan in coastal South Carolina is shorter than the warranty on the wrapper, because heat, UV, humidity and storms age asphalt faster here. Charleston Roofs and Windows uses the roof's age and condition together to decide between repair and replacement.
What Ages a Shingle Roof Here
- Summer heat and UV. Asphalt dries out and shingles curl.
- Heat cycling. Hot days and cooler nights expand and contract the roof, loosening seals.
- Humidity and algae. Moisture feeds streaks and holds water against the shingle.
- Tropical storms. Wind lifts and creases tabs, breaking the seal even when nothing blows off.
- Poor attic ventilation. Trapped heat bakes shingles from below.
Shingle Repair vs. a New Shingle Roof
Usually a repair Well inside its expected lifespan
Usually a new roof 20 years or older
Usually a repair A handful after one storm
Usually a new roof Shingles lifting on several slopes
Usually a repair Only in one worn spot
Usually a new roof Bare spots across the roof, granules in every gutter
Usually a repair One leak at a vent, valley or flashing
Usually a new roof Leaks in more than one place
Usually a repair Solid under the damage
Usually a new roof Soft or sagging in several areas
Usually a repair Close match still available
Usually a new roof Old color discontinued or badly faded
The Color Match Problem
New shingles never match a faded roof perfectly. On a younger roof that's a small trade-off. On an older roof with patches already on it, Charleston Roofs and Windows will tell you when a full replacement makes more sense.
"Grady did a great job replacing damaged shingles from the Jun downburst. He had everything he needed to do the repair and was here and finished in less than an hour."
