Stopping Black Streaks Before They Start
The dark streaks on many Mississippi roofs are usually a type of algae that feeds in warm, damp conditions. It is mostly cosmetic at first but can hold moisture against the shingle surface. For new roofs we recommend algae-resistant shingles, which contain granules designed to slow growth. On existing roofs, a gentle low-pressure cleaning is safer than pressure washing, which strips granules.
Does Shingle Color Affect Attic Heat?
Lighter shingle colors reflect more sunlight than very dark ones, and some product lines include reflective granules. Color is only part of the picture, though. Attic ventilation and insulation usually matter more for comfort and cooling bills. We look at intake and exhaust venting on every Flora job and can explain options on our roof ventilation page. Pick a color you like, then let ventilation do the heavy lifting.
Installation Details That Prevent Leaks
Most storm leaks we repair trace back to installation shortcuts rather than the shingles themselves. On our roofs, crews focus on:
- Correct nail placement in the manufacturer's nailing zone, with the specified number of nails per shingle
- Ice-and-water barrier in valleys and around penetrations
- New drip edge and step flashing instead of reusing bent metal
- Sealed starter strips along eaves and rakes, where wind uplift begins
Homeowners weighing metal can compare options on our Flora metal and shingle roofing page.
Repair, Maintain or Replace
A roof with a few damaged shingles and good overall condition is usually a repair. Curling, widespread granule loss, repeated leaks in different spots or soft decking suggest replacement is the better investment. After storms, we help homeowners document damage for insurance with photos and a written scope. Between projects, a quick inspection every year or two keeps small issues small, especially around chimneys and vents.
Common Questions
Can algae streaks be removed from my current roof?
Often they can be lightened with a soft-wash cleaning designed for roofs. Avoid high-pressure washing, which damages shingles. Installing zinc or copper strips near the ridge can help slow regrowth on some roofs.
Will a lighter roof lower my electric bill?
It can help a little, especially combined with good attic ventilation and insulation. The size of the benefit varies by house, so we focus on the whole system rather than color alone.
What is the most common cause of storm leaks in Central Mississippi?
In our experience, it is flashing and nailing problems: improperly nailed shingles that lift in wind and old flashing around chimneys, walls and vents. Careful installation addresses both.
Do you serve both homes and businesses in Flora?
Yes. We handle residential shingle and metal roofs as well as low-slope commercial roofs, and we offer free estimates for both.
