The roofs of Havana, from the tobacco-era downtown to the red-clay hills
Havana's roofs are not one story. Twenty minutes north of Tallahassee on US 27, just shy of the Georgia line, the town is a mix that no suburb builder ever planned: a surviving row of century-old brick storefronts around the old tobacco downtown, frames and double-wides on the red-clay hills outside town, and the tall sheds and barns of the old shade-tobacco country tucked back off the county roads. Each of those roofs asks for a different hand, and the one thing they have in common is that high pressure is wrong for all of them. The brick buildings' composite shingles and the steep standing-seam metal on the old tobacco sheds and rural outbuildings both carry growth that a blast would only damage - stripping granules off the shingles the way the North Florida sun is already working to do, or driving water up under the metal panels and along the fastener lines where rust starts. We read the roof before the pump runs and match the chemistry and the pressure to what is actually underfoot, because getting the method right is what stops a clean from turning into a repair list.
The shade-tobacco sheds and the rural metal roofs out on the county roads
Drive out of the downtown grid toward Scotland, Yonkers, or the tobacco country along the county roads and the roof you see most is metal. The old shade-tobacco sheds that put Gadsden County on the map - tall, vented barns built to hang tobacco until it cured - carry standing-seam and corrugated panels that have watched a lot of North Florida summers. Those roofs have a specific problem that no suburb shingle has: the shallow valleys between panels and the rows of fasteners hold moisture and pine litter, and on the Gulf side of a hard Georgia-line freeze they stay wet long enough to grow a streaky grey oxidation and, around the fasteners, the start of rust. Walking one of these roofs to clean it is out of the question - the panels dent and the seams pop - so we work the metal from a ladder and the ground, low pressure the whole way, treating the valleys and the fastener lines by hand and never pushing water up under the laps. On the panels that have already greyed, a soft clean brightens the finish and slows the oxidation without stripping what little coating is left, which matters on a shed roof that is staying up and in service.
What the old brick downtown actually needs off its rooflines
The historic block around the antique shops and cafes is the part of Havana people drive twenty minutes to see, and its roofs deserve the same care as its facades. These are mostly modern composite shingle on the brick buildings - replaced at some point over the last thirty years - sitting on parapet walls low enough that growth transfers easily from the shaded brick to the shingle edge. The red-clay-dusted morning air and the constant shade of the street trees keep the north roof slopes damp, and that is exactly the recipe for the black algae streaking that hits North Florida shingle roofs: it thrives wherever moisture sits through the deep Florida humidity. We clean down the pitch from the parapet, work the transition where the shingle meets the old mortar, and hand-clean the vents and the flashing where the roofline steps, because on a historic building the detail is the point. A clean roofline on the old storefronts reads as care from the street - it is one of the first things a visitor clocking the block for the first time notices - and it protects the roof underneath from the constant wet-dry cycling that ages shingles years ahead of their time.
The Georgia-line mornings that keep a Havana roof damp
Havana sits on the rolling red clay of northern Gadsden County, and its position near the Georgia border changes the rhythm of a roof clean in a small but real way. The town's mornings run foggy and damp for more of the year than Tallahassee's do - the low ground and the Gadsden clay hold the moisture that rolls up off the Gulf, and a roof that faces north can stay wet well past midmorning. That long damp window is why the north slope and the oak-shaded slopes darken first and show algae again soonest, and it is why the maintenance interval on a Havana roof is set by the shaded side, not the sunny front you see from the road. It also means a clean done in the wrong season wastes itself: we steer the timing toward the drier stretch after the heaviest spring pollen drop and away from the summer afternoon-thunderstorm months, so the roof holds its freshly cleaned look instead of the growth recolonizing within days. Kill the growth at the root, clear the valleys and the gutters, and let the roof dry properly, and a Havana roof typically holds two to three years even under that fog and shade.
On the red-clay hills and the honest boundary of what we fix
On the clay hills the roof most often needs, more than cleaning, is for the growth to be treated rather than blasted. The moss that roots into the valleys and the lichen that grips the shaded slopes hold water against the shingles through the long damp stretches, and that constant wet-dry seesaw is what wears granules loose and curls the shingle edges well before a roof of its age should be failing - shingle damage that reads as age but is really decades of water sitting in place. Cleaning that growth off protects a roof that is still sound, and being honest about the boundary is part of the job: when shingles are already shedding granules on their own, curled, cracked, or lifting, no wash undoes that - that is the roof reaching the end of its life, and the right move there is a roofing contractor, not a cleaning crew. For the roofs where a clean is the right call, we soft wash, hand-work the valleys and the penetrations, flush the gutters so water actually moves, and protect the beds and plants around the perimeter from the runoff. Most homes are done in a few hours with a flat price up front, and the job pairs naturally with a house wash while we are set up on site. See our roof cleaning cost guide for what the work runs. And whether your roof is old brick downtown or metal out in the tobacco country, a couple of photos of the worst streaks and the roof's material will get you a straight answer on whether it is a cleaning or a repair.
