A Season-by-Season Roof Check for East County Homes

Why do the sunny faces wear first?

A covering heats through the afternoon on its sunny faces and cools each night. Over time that daily movement loosens granules, dries the asphalt and cracks the tabs at the nail line.

The face that takes the most afternoon sun is usually the first to show granule loss. It may look only a little faded from the street while the mat is already bare in patches. A close look from a ladder at the eave, done safely, shows what the street view does not.

The shaded face often lasts longer, which is why a replacement can sometimes be done one slope at a time. The technician records the condition of each face, so the decision rests on the wear that is there.

What does the year look like on the roof?

The calendar below divides the year into four checks. Each one names what to look for and what to do about it, so the owner has a routine rather than an occasional scramble.

The check is short, and it is done from the ground and from a stable ladder where that is safe. A photograph from the same spot each time is the most useful record, because it shows change that is easy to miss by memory.

The table does not give dates for the seasons, since the timing of the sun and the heat varies from year to year. The sequence of checks is what matters.

What does the attic need on a hot day?

The attic needs a path for the air. The intake at the eave and the exhaust at the ridge work as a pair, and a blocked intake defeats any exhaust fitted above it.

Insulation pushed against the soffit is the most common block, and it is cleared with baffles that keep a channel open at each rafter bay. The technician measures the openings before deciding what to add.

A powered fan can move air, but it draws replacement air from wherever it can reach. An attic with no intake can pull air from the house below, so the intake is checked first and any fan is considered only after that.

• Look for insulation pressed against the soffit
• Look for a ridge with no vent line, or a vent that has been covered over
• Look for darkened sheathing near the ridge on a hot summer afternoon
• Note the attic temperature in the afternoon, before and after any change

When should a homeowner call a technician?

Call when a sunny face shows bare mat, when a stain appears on a ceiling or when the attic is hot enough to feel wrong. The earlier the check, the smaller the repair is likely to be.

A technician reads the roof from the ladder and the ridge, and walks only the sections where weight can safely go. The attic is read from the access hatch, following the framing up the slope.

The visit ends with a written note of the condition and the repair it appears to need. The note becomes the first line of the file, and the next seasonal check is compared against it.

How is a sunny face checked without climbing?

A sunny face is checked from the ground with binoculars or a camera, and from a stable ladder at the eave where that is safe. The aim is to see granule loss, curling and cracks along the nail line before they become leaks.

From the ground, the color of the covering shows the wear. Bare black patches and a faded, uneven surface are the signs of granule loss, and a photograph taken from the same spot each season makes the change visible.

From a stable ladder at the eave, the lower courses and the nail line can be seen more closely. A ladder must be set on firm footing, tied off at the top and kept inside the rails, and no one should lean out to reach a further section.

How are attic readings recorded and compared?

An attic reading is a simple temperature taken in the afternoon, in the same place, with a note of the outside air. The readings before and after a change show whether the change helped.

A thermometer hung at the ridge line in the afternoon is a useful, low-cost record. Note the time, the outside temperature and whether the vents were open. A set of readings across a summer shows the pattern more clearly than one reading does.

A technician can add a more detailed reading when a fault is suspected, but the homeowner's simple record is often enough to show whether the attic is running hot and whether the change helped after the work.

What changes after a seasonal check?

A seasonal check changes the plan when it shows a new fault, a worsening one or a sign that a repair has worked. The owner then decides whether to act now, plan a repair or keep watching.

A new stain, a new crack or a new gap at a joint is a reason to call a technician. A worsening fault that was already noted is a reason to move the repair up the list, and a fault that has been repaired and has not reappeared is a sign that the work held.

The check is kept in the same file as the scope, so the owner has a single record of the roof's condition over time. A technician reading that file can see the pattern and the repair history at once.

Why is ventilation part of a sun check?

Ventilation is part of the sun check because the attic carries the heat of the covering into the house. A roof whose attic cannot move air is hotter from below and wears sooner from the inside.

The attic is the part of the roof that a homeowner can check most easily from the hatch, on a cool morning and again in the afternoon. The difference between the two readings shows how hot the attic runs.

Where the intake is blocked, the technician clears it. Where the exhaust is missing, a ridge vent or a set of roof vents is added. Both changes are recorded on the scope, with the reasons.

What does a homeowner do if a fault shows between seasons?

A fault that shows between seasons is worth a call rather than a wait. A new stain, a lifted tab or a crack that is growing is the sign that the covering is working against the weather, and the sooner it is looked at the smaller the repair is likely to be.

A homeowner can note the fault, photograph it and call (833) 751-2102. The technician sets a time for the visit, and the first step is to read the roof and the attic, not to quote a repair from the phone.

The fault is recorded on the seasonal file with the date it was found. The repair is then planned against the record, so the owner can see how the fault developed and whether the same spot shows wear again later.

Does the sun affect the flashing as well as the covering?

Yes. Sealant and metal flashing both respond to heat, and the sealant at a joint can crack and pull away from the metal. A flashing that was sealed well can open at its joint after a few seasons of strong sun.

The joints at the chimney, the vents and the skylight curb are the most exposed. A crack in the sealant lets water in behind the metal, and the stain often appears on the ceiling some distance from the joint.

A technician re-seals or re-flashes the joint, and the covering is lapped over the flashing so water runs over the joint rather than into it. The work is recorded on the scope with the reason for it.

Who should be told about the seasonal checks?

The seasonal checks are for the owner, and they are shared with a technician when a visit is booked. A tenant or a neighbor is told only what affects them, such as a tarp or a day of noisy work.

A homeowner who rents the property keeps the same file and shares the relevant parts with the tenant, such as the list of what to report and the number to call. A tenant who sees a stain should report it at once, with a photograph and the date.

A neighbor whose boundary is close to the roof may need notice of work overhead. The owner tells the neighbor the days, and the crew keeps its materials and ladders on the owner's side of the line.
