🍂 November in St. Martinville: grinding season is under way in the fields around town, and harvest dust hangs over the parish through the season. In town, the live oaks over the Teche keep whole streets in shade, and roofs under them start the day damp. Fall is when a summer of black growth shows up worst, and a wash now clears it before winter.
⚡ Quick Answer, Roof Cleaning in St. Martinville
Most St. Martinville roofs with life left in them need a soft wash every 2–3 years. St. Martinville is a city of about 5,400 people on Bayou Teche, the seat of St. Martin Parish, with some of the oldest houses in Louisiana. Bayou air, live oak shade and roughly 60 inches of rain a year keep roofs here growing algae and moss steadily, and the town's older roofs need a gentle hand. On any roof we inspect first: if granule loss, curling or soft spots say the roof is worn out, we tell you to call a roofer instead. Lafayette Roof Cleaning serves St. Martinville (70582) with a written price and a free estimate returned within 2 hours.
———-The St. Martinville Roof Problem
Why Do Roofs in the Petit Paris of Louisiana Grow Black?
St. Martinville began in the mid-1700s as Poste des Attakapas, a French post on Bayou Teche, and in 1765 Acadian exiles made it the heart of what became Cajun country. St. Martin de Tours Church, founded by those settlers in 1765 and known as the Mother Church of the Acadians, still anchors the town square; the present church dates to 1840. French Royalist refugees gave the town its nickname, Le Petit Paris, and in 1847 Longfellow published Evangeline, making the oak on the Teche one of the most photographed trees in the world.
A town that old has roofs of every age, but the weather over them is one weather: about 60 inches of rain a year, bayou humidity that never fully leaves, harvest dust off the cane fields, and deep shade under live oaks that were old when the church was new. That is the recipe GAF describes for black-streak algae (Gloeocapsa magma), with moss layered in wherever the oak canopy is thickest.
1847
the year Longfellow published Evangeline
The poem made this town's story famous around the world. The live oaks that shade Bayou Teche shaded the lovers in that story; they shade St. Martinville's roofs too, and a shaded roof in this climate grows moss and algae faster than any other.
What We Actually Find on St. Martinville Roofs
Every town in Acadiana has its own roof problems. These are the four we see again and again in St. Martinville.
1
The Old Houses Around the Square
Most buildings around the historic square date to the 19th century, and the streets behind it hold the oldest housing stock of any town we serve. Steep pitches, thin older shingles and metal roofs of real age are common here. These roofs get our gentlest treatment and our most honest verdicts: some need washing, some need a roofer first.
2
Live Oak Shade Along the Teche
The Evangeline Oak is the famous one, but the canopy is everywhere. A roof under oaks stays damp hours after the street dries, gets fed leaves and debris in its valleys, and grows moss on the shaded slopes the way open roofs never do. Shade is the single biggest reason one roof here greens up years before its neighbor’s.
3
Cane Country Dust on the Town's Edges
St. Martinville sits in working cane country. In the fall the harvest runs for months, and cane dust and field dirt ride the wind onto roofs at the edges of town; spring pollen is just as heavy. The film is food for algae: rain wets it instead of washing it off, and the streaks follow.
4
Metal Roofs on Shops and Farm Buildings
Metal covers a lot of St. Martinville beyond the houses: shops and sheds in town, barns and equipment buildings on the farm roads out, and a good share of homes. Mildew and dark film build up near seams and under oaks, and rust starts at the fasteners. Washing removes growth, not rust damage or holes.
Which Option Fits Your St. Martinville Roof?
Ask any roof cleaner two questions before you hire them: How do you clean? What pressure do you use? Our answer: low pressure only.
Wait and Watch
a newer roof in full sun with no visible growth may not need anything yet. We’d rather tell you to wait.
Soft Wash
visible algae or moss on a roof with life left, including most of the older in-town roofs. Most St. Martinville roofs we clean.
Pressure Washing
Fine for concrete. Not for shingles, ever, ARMA says it’s likely to damage asphalt roofing.
Roofer
Missing shingles, heavy granule loss, or leaks need repair, not cleaning.
The Honest Picture
Is Algae Staining Actually Hurting Your Roof?
St. Martinville sells a look: the historic square, the old church, the Evangeline Oak. So the quiet part first: cleaning a roof for how it looks is a legitimate reason, and scientifically it is the main reason there is. The Canadian Asphalt Shingle Manufacturers’ Association (CASMA) says algae staining is not a defect and has not been shown to shorten shingle life; a blackened roof on a 19th-century house is an appearance problem, not a structural one, and growth also shows in the aerial photos insurers review (Louisiana law R.S. 22:1339 limits decisions based only on images older than 24 months). The physical threat under the live oaks is moss, holding moisture and lifting shingle edges, and the other threat arrives on a truck: a pressure washer, which ARMA says is likely to damage asphalt roofing and GAF says can dislodge protective granules.
—————The Honest Comparison
Why Does Pressure Washing Fail on Older Roofs Most of All?
The complaint we hear most from St. Martinville homeowners who already paid someone once: “It looked clean that week, and worse by the next summer.” Pressure washing strips the surface while the algae roots survive inside the shingle, and it tears away the protective granules. On an older roof in the historic part of town, with granules already thin, one hard washing can be the difference between a roof with years left and a roof that needs replacing.
✕ What Fails
Pressure washing any shingle roof, worst of all an older one with thin granules
Scraping moss off by hand and tearing the shingle surface with it
Store-bought spray treatments that bleach the surface and leave the roots alive
Selling a wash for a roof that’s actually worn out
✓ What Works
An honest look first, wait, wash, or roofer, in that order
Treatment matched to the roof, killing growth at the root
A gentler mix and careful rinse for metal roofs
Written price agreed before we start, from a crew 25 minutes away
Results that last 2–3 years, not 2–3 months

St. Martinville roof cleaning FAQS
Do you serve the whole 70582 area, including Parks and the roads along the Teche?
Yes. The 70582 ZIP covers St. Martinville and Parks, and we work the whole of it: the historic streets in town, the bayou roads north and south, and the farm roads running out toward the cane fields.
My house is one of the old ones near the square. Is a soft wash safe on an older roof?
It is the safest cleaning an older roof can get, because nothing is blasted or scrubbed: the treatment does the work at garden-hose pressure. But age cuts both ways, so we inspect first. If the shingles are too far gone to clean honestly, we will tell you a roofer is the right call before you spend anything on a wash.
Can you wash the metal roof on my shop or barn?
Yes. Metal grows less than shingles but still gathers mildew and dark film near seams and under trees. We use a gentler mix and rinse carefully around fasteners. One limit, stated plainly: washing removes growth, it doesn’t repair rust or holes.
How often does a St. Martinville roof need cleaning?
Every 2–3 years suits most roofs here. Homes under the live oaks and along the bayou tend to need it closer to every 2 years. Keeping valleys clear of oak leaves and trimming limbs back from the roofline stretches the time between cleanings.
Will soft washing void my shingle warranty?
No. Soft washing is the low-pressure cleaning method shingle makers point to. High-pressure washing is the one they warn against, because it strips the granules that protect the shingle.
We also serve nearby Breaux Bridge and Cecilia. If the roof is the worry, start with roof cleaning vs roof replacement.
