Researching Roof Coating in Greater Orlando Metro Area?
APC Roofing tracks how air moves through the attic and how surfaces up top are holding up, and records storm damage in a plain written account.
Phone 407-270-1129 and a roofer comes out to see what is going on up there.
Natural Draft – True for the Whole Setup
A vent up top stays idle unless outside air is entering the attic somewhere lower down, since a closed-off attic gives that high vent no source to draw from. Shelf after shelf of venting stock turns out to be outlet equipment, and a device fed by nothing carries very little air through that space.
The Roof Overhang – Easy to Lose Under Fill
Along the wall plate, the rafter framing squeezes down to a narrow few inches, and that slim gap is the whole intake path for the space above. A blower run out to the eave seals that choke point under the fill, a slip almost any blow-in crew makes.
The Small Baffle – Installed by Hand
A rigid guide set between two rafters holds insulation off the narrow gap below the deck, so a path stays clear from the wall plate up to the peak. Placing a baffle is done as attic carpentry, not as work on the shingles above, a detail some crews hurry past on a tight schedule.
The Sizing Approach – Worth Getting Right
Trade guidance calls for one square foot of net free vent area for every 150 square feet of attic floor, and that ratio eases to one-in-300 once the ceiling below stays air-sealed with intake and exhaust in balance. The number a vent's label states falls short of the opening cut to receive that vent, and any sizing calculation should run off that figure instead of the rough width of the hole.
The Summer Stretch – Worse as the Season Wears On
An attic sealed against any airflow turns into an oven compared with the air outside, a difference plain enough for anyone who steps in to notice. Direct daylight hitting the surface accounts for most of what ages asphalt, with little added by whatever is happening in that space below. In the warmest part of our service area, balanced venting spares the deck and framing under the shingles from extra heat and moisture, which limits curling and granules coming loose ahead of time.
What Causes an Ice Dam: Building Up, Not Just Cold
Where winters turn hardest in our service area, the aim is keeping an attic near the temperature outside, though the issue differs once the warmer months arrive. Heat escaping from the living space below melts the snow against the deck, and the water freezes again at the cold eave. A ridge shaped there blocks later runoff, and the backup climbs up under the shingles above.
Where the Duct Terminates – Often Installed Halfway
What a bathroom fan is meant to do is remove moisture from the house, not merely off the ceiling. In quite a few homes the ductwork dead-ends in the attic space rather than outside, a gap between plan and reality that shows up years later. Boards over that particular room stain black from damp air landing there again and again, visible the moment anyone shines a light into that corner of the attic. Correcting the run so the duct reaches open air outside fixes the issue, handled from inside the house.
Reading the Stain – a Distinction That Saves Money
Warm household air slips into the attic through gaps around fixtures and the access hatch, helped along by nothing more than rising air currents. Once nighttime temperatures fall, that air turns to beads of water beneath the deck, and that condensation eventually drips onto the insulation below. A patch that appears during a dry stretch points to humidity rising indoors, whereas darkening that only follows a storm traces back to water entering from outside.
Where the Skylight Meets the Covering – a Question of Flashing
Factory sealing protects a glazed unit right at the plant, and almost never lets water through unaided. Water instead finds a way in at the joint between that fixture and the surrounding covering, a junction that takes more stress than any other part of the assembly. Manufacturers supply each unit's flashing kit, which combines step pieces, a head piece and an apron.
Intake and Exhaust – What Keeps Things Working
A job's vent area is meant to balance out close to evenly between the low openings and the high openings, with the load not landing mostly on one end. If the two cannot be brought to an exact match, the larger share goes to whichever set sits lower, because exhaust running short only slows the airflow, while intake running short brings the airflow to a stop.
Exhaust Choices – Case by Case
A ridge-mounted vent draws air along the peak from end to end, installed as one uninterrupted slot cut along the deck. A single box vent serves only a small patch of shingle, which is why a design built from hips rather than one long high edge often uses a handful. An electric fan pulls air from whatever opening surrenders air most readily, and a blocked soffit leaves the rooms below as the supply instead.
Different Skylight Bases – Matched to What the Space Needs
A curb-style unit rests on a wood frame raised above the deck, with the covering material extended up along the sides. A raised-frame mount suits a section of roof with little pitch, where water can gather near the opening, because the added lift keeps the opening safely away from the surface below. A deck-mount unit fastens directly to the sheathing and holds up on roofs built to shed rain without assistance, and sits lower than the curb-mounted version.
Skylight Styles: Fit to the Setting Below
A fixed unit has no moving parts of any kind and stays sealed shut, placed there for daylight alone, with no other function. A venting assembly lifts open on a crank, a pole or a small motor, and vents warm air from the room beneath. A tubular skylight moves daylight down a reflective tube and into a hallway or closet, through a roof opening well short of the size a standard fixture needs.
Skylight Installation Work – Accounting for What Already Exists
An opening beyond the width of the rafter spacing requires cutting one rafter and framing a header into the resulting gap, with that new support carrying the load the removed piece used to bear. Wiring, ducting or a plumbing vent occupying that bay must be relocated, before the job can go forward. The space between the roof gap and the ceiling below needs framing, insulation and a finished interior surface, so nothing escapes into the attic through that opening along the way.
Condensation on the Skylight: Explained Indoors, Not on the Roof
Over a bathroom or kitchen, the glazing is the coldest surface in a humid room, colder than any wall or ceiling nearby. Droplets that travel down to the frame and drip from there can look exactly like a leak, with the roof in good condition throughout. The remedy is an indoor one, not a roof repair, either a stronger fan run longer or a shaft with better insulation.
The Rooftop Layer – What Comes Next
A coating is applied as a liquid, which gets rolled or sprayed onto an existing covering and hardens into a single unbroken skin. A coating builds up a surface layer, without replacing whatever lies below. A sound, dry and well-drained covering is what a coating is meant for, not one already in poor shape or holding water.
Chemistry Types – Suited to the Job at Hand
Acrylic coating is water-based and reflects sunlight well, the most frequently chosen option, but warm, dry weather is needed to set properly, and pooling water causes problems. A silicone coating handles standing water fine and cures across a wider span of temperatures, but dirt clings easily, and the surface becomes slick once wet. Urethane holds up under repeated foot traffic near rooftop equipment, often used as a tougher finish coat over a separate base layer.
Surface Prep Work – Worth Doing Properly
Peeling in a coating is almost always the result of a poor bond at application, not a defect in the coating material. Any of dirt, chalk residue, oil film or old sealant prevents adhesion from taking hold, so the new coating never truly grips the surface below. Proper preparation starts with washing the surface and allowing full drying time, followed by primer, per the product's instructions, where called for, with repairs to seams and flashings finished before coating goes on.
A Roof Layer's Limits – Not a Substitute for Repairs
Since a coating seals the surface, trapped moisture in a wet deck or soaked insulation blisters the new skin rather than escaping. A scan or a core cut settles whether the covering is ready before coating goes ahead, because coating before that surface is properly prepared only worsens the problem. A coating cannot create slope where none exists, so a spot that already holds water continues to hold water once the coating is down.
Warning Signs – Things Worth Mentioning
- Rust-colored staining around nail points inside the attic, visible with a quick check using a flashlight.
- Insulation carried all the way to the eave with no baffle installed, a detail often missed on a fast job.
- Curling shingles or early granule shedding on the surface, often a sign of poor attic airflow.
- Ice building along the eave after a snowfall, at the colder end of our territory, sometimes paired with discoloration near the inside edge of the roof.
- A ceiling stain visible on an otherwise dry day, unrelated to conditions beyond the property.
- Water tracking from a skylight's corner after a hard rain, most often linked to the flashing around that opening.
- Peeling, blistering or chalking on a coating along a seam or edge, an indication that adhesion has broken down there.
- A bath fan duct left unconnected in the attic instead of running to an outlet, simple to spot on a walk through the attic.

The Follow-Up After a Storm – Our Part in the Process
The roof gets a full inspection, and any damage is photographed and measured, and every part of the roof is gone over so nothing is overlooked, and a written account is sent to the homeowner afterward. Any loose pieces are saved rather than discarded, until each has been checked, a small step that keeps everything straight.
Order Worth Getting Right – Why Timing Is Everything
Insulation pushed beyond the baffle line closes off the very intake meant to stay clear, undoing the very reason that piece was placed there. Adding vents before ceiling gaps are closed up pulls conditioned air out of the house instead of moist attic air, wasting energy the household already paid for. The correct order runs sealing before insulation, and insulation before sizing the vents, with baffles included as part of that stage.
