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.
Dial 407-270-1129 and a roofer comes out to see what is going on up there.
The Chimney Effect – True for the Whole Setup
Nothing leaves through a vent near the peak until outside air is coming in somewhere below, because an attic taking in no outside air gives that high vent nothing to draw on. 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 Overhang – a Thing Insulation Can Erase
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. Loose fill blown all the way out to the edge buries that choke point completely, a step almost any blow-in crew gets wrong.
The Small Baffle – Easy to Overlook
A rigid strip set between rafters keeps fill clear of the narrow gap near the roof 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 Math – Not Just a Guess
Standard practice puts one square foot of net free vent area against every 150 square feet of attic floor, and the benchmark eases to one-in-300 once the ceiling below stays well air-sealed with intake and exhaust close to even. The number stamped on a vent measures smaller than the opening framed for that vent, so a sizing calculation relies on that figure, not on how large the hole looks from underneath.
Summer Above the Ceiling – a Seasonal Toll
An attic sealed against any airflow turns into an oven compared with the air outside, with the difference easy to feel just by stepping into the space. Direct daylight hitting the surface accounts for most of what ages asphalt, and whatever sits below adds very little to the total. 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.
An Ice Dam Overhead – Seen After a Hard Freeze
Where winters turn hardest in our service area, the aim is keeping an attic near the temperature outside, though the reason changes once the warmer months arrive. Heat escaping from the living space below melts the snow against the deck, and that water refreezes at the unheated eave below. The ice built along that edge stops later runoff from draining, and the backup gets forced under the shingle courses.
The Duct – Judged by the Finish Point
What a bathroom fan is meant to do is remove moisture from the house, not only from the room. On a fair share of homes the run for that duct quietly lets out in the attic, often missed during a routine final inspection. The deck above that room turns dark from repeated moisture over time, noticeable to anyone who looks up with a flashlight in hand. Running that duct to a real outdoor outlet clears the trouble, and the repair happens entirely from inside.
The Stain's Origin – Different Sources, Different Fixes
Household air moves upward into the attic through small openings around light fixtures and the hatch, carried on nothing more than the basic pull of rising heat. As the temperature falls after dark, that air forms droplets under the deck, and that condensation drips down onto whatever sits 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
A glazed unit comes sealed from the factory, and hardly ever gives way without some other cause. The real entry point sits at the seam between that fixture and the surrounding covering, a junction that works loose faster than anything else close by. Every unit comes with the manufacturer's flashing kit, which comes assembled from step pieces, a head piece and an apron.
Matching Intake to Exhaust: a Question of Proportion
A job's total vent area is meant to split close to evenly between the low openings and the high openings, so the burden does not settle mostly on one end. When an exact match is not possible, more of the share shifts to whichever set sits lower, since running short on exhaust merely slows the airflow, but running short on intake stops the airflow outright.
Styles of Exhaust – What Fits Here
Ridge venting works along the whole peak in one unbroken run, installed as one uninterrupted slot cut along the deck. One box vent covers just a small area of the surface, so several are placed across a structure shaped with hips rather than one long high edge. A fan wired into the roof draws air from whatever path is easiest, and a blocked soffit turns the rooms below into that supply instead.
The Base Beneath a Skylight: a Detail Worth Getting Right
A curb-mounted unit rests on a raised frame of dimensional lumber, with the covering run up along the sides. A frame-mounted style fits a low-slope section where standing water can reach the opening, because the added lift keeps the opening safely away from the surface below. A unit resting on the deck fastens right to the sheathing and holds up on roofs that clear rain fast, sitting lower than the curb-mounted version.
Choosing a Skylight Type – Not Just One Design
A fixed unit has no moving parts and never opens, installed purely to bring daylight down from above. A venting assembly opens with the help of a crank, a pole or a small motor, letting built-up warm air out of the room below. A tubular unit carries daylight down a reflective tube into a hallway or closet, through a roof opening far narrower than a standard fixture.
Skylight Rough-In Work – More Involved Than the Outside Suggests
An opening that runs past the space between rafters means cutting one rafter and framing a header into the gap, with the new support now bearing the load the removed piece used to bear. Electrical wiring, ductwork or a plumbing vent passing through that bay has to move, before the surrounding carpentry can be completed. A channel running from the roof gap down to the ceiling requires framing, insulation and a finished surface inside, so light and air do not travel into the attic along the way.
Skylight Sweating – a Problem Born Indoors
In a bathroom or kitchen, the glazing is usually the coldest surface once the air turns humid, colder than the walls and ceiling around that space. Condensation that gathers and moves to the frame before dripping can look just like a leak, though the roof is in fine condition. The fix belongs indoors, not on the roof, either a stronger fan run longer or a shaft with better insulation.
The Rooftop Layer: Not a New Roof, Just a New Surface
A coating is a liquid material, which gets rolled or sprayed over an existing covering and hardens into one continuous skin. A coating adds a layer on the surface, without replacing whatever sits beneath. A covering that is sound, dry and well-drained is exactly what a coating is meant for, not one already in poor shape or holding water.
Chemistry Types – Not a Random Selection
An acrylic coating is water-based and does well reflecting sunlight, the option chosen most often, but warm, dry weather is needed to set properly, and pooling water causes problems. Silicone tolerates standing water well and cures across a broader range of temperatures, though dirt sticks to the surface, and the surface gets slick when wet. A urethane coating fares well against foot traffic near rooftop equipment, and is frequently laid down as a tougher top coat over another base layer.
Prepping the Surface – the Part Nobody Sees Later
A peeling coating nearly always points back to a poor bond made at application, not any shortcoming in the material. Dirt, chalk residue, an oil film or old sealant will each keep adhesion from taking hold, leaving the coating adhered to almost nothing underneath. Proper preparation starts with washing the surface and allowing full drying time, followed by a primer coat where called for, and any needed repairs to seams and flashings beforehand.
What a Layer Leaves Undone – Where Judgment Still Matters
Because sealing the surface is what a coating does, trapped moisture in a wet deck or soaked insulation blisters the new skin rather than escaping. A scan or a core sample confirms whether the covering is ready before any coating is applied, because coating over a surface that needs more time only locks the problem in. A coating does not create any slope, so a low spot that already holds water keeps holding water afterward.
Warning Signs – Noticed During a Walk-Through
- Rust-colored marks around nail tips inside the attic, easy to spot with a flashlight.
- Insulation blown out to the eave with no baffle set in, a detail easy to miss once work wraps up.
- Shingles that curl or shed granules earlier than expected, often linked to conditions in the attic below.
- Ice collecting along the eave after snow, at the colder end of our territory, often paired with discoloration just inside the roofline.
- A ceiling stain visible on an otherwise dry day, unrelated to anything outside the house.
- A skylight corner with water tracks after heavy rain, most often linked to the flashing around that opening.
- A coating peeling, blistering or chalking along a seam or edge, a signal that the material beneath has let go.
- A bath fan duct sitting disconnected in the attic rather than reaching an outlet, easy to find with a flashlight and a look around.

The Follow-Up After a Storm – What We Take Care Of
A full inspection covers the roof, and any damage gets photographed and measured, and each area is worked through so nothing is skipped, and the homeowner is given that written account afterward. Any loose pieces are saved rather than discarded, until each has been checked, a plain step that keeps nothing lost along the way.
Sequence Matters – Each Step Builds on the Last
Insulation carried past the baffle line buries the very intake meant to stay open, undoing the very reason that piece was placed there. Putting in vents before the ceiling is closed up draws conditioned air from the house rather than moist attic air, doing the opposite of what the attic actually needs. Sealing happens before insulation, and insulation happens before the vents are sized, with baffles put in during that step.
