Common issues we see in Hillsboro:
Wind-lifted shingles
Flashing failure at roof penetrations
Valley leaks
Moss growth in shaded subdivisions
Aging builder-grade materials
If you’re noticing lifted shingles, leaks, or signs of wind damage, schedule a professional roof inspection before minor issues turn into costly repairs.

Siding is not just cosmetic, it protects framing from moisture intrusion.
In growing Hillsboro subdivisions, common siding issues include:
Warping or separation
Improperly sealed window trim
Moisture intrusion behind panels
Storm-related impact damage
If your siding shows staining, softness, or swelling, it may be allowing water behind the surface.

Chimney leaks are one of the most overlooked sources of water intrusion.
In Hillsboro homes, we frequently see:
Failing chimney flashing
Cracked masonry
Deteriorated mortar joints
Improper caps
Water staining near fireplaces
Heavy winter rains expose weak chimney intersections quickly.

In Hillsboro’s climate, most asphalt shingle roofs last between 20–30 years depending on installation quality, ventilation, and exposure to moss and wind. Homes in shaded subdivisions or near tree-lined streets may experience accelerated wear due to trapped moisture.
Regular inspections help extend roof lifespan and prevent premature replacement.
Due to prolonged rainfall and seasonal wind, we commonly see:
Flashing failure around roof penetrations
Valley leaks
Wind-lifted shingles
Moss buildup
Builder-grade shingles nearing mid-life
Early repair prevents larger structural damage.
Repair is often appropriate for isolated leaks or localized damage.
Replacement may be recommended when:
Shingles are deteriorating across large areas
Multiple leaks exist
The roof is near the end of its lifespan
Storm damage affects structural integrity
A professional inspection provides clarity.
Because of Washington County’s heavy rainfall and moss conditions, inspections every 1–2 years are recommended. Inspections are also advised after significant wind events.
Yes. Wind can loosen shingles and expose seams without obvious visible damage. Leaks may appear weeks later during heavy rainfall.
Hillsboro’s damp climate and shaded neighborhoods create ideal conditions for moss growth. Moss traps moisture and can lift shingles, leading to premature wear.
Moss management is preventative maintenance, not cosmetic treatment.
Absolutely. The intersection where the chimney meets the roof is one of the most common leak points. Failed flashing allows water intrusion during prolonged rain.
We inspect both the roofing system and chimney structure together.
Look for:
Cracked mortar
Loose bricks
Rusted or missing chimney caps
Water staining near fireplaces
Leaks near the chimney during rain
Freeze-thaw cycles can accelerate masonry deterioration.
Yes. Water can travel downward behind siding panels, leading to rot, mold, and structural damage. Exterior systems work together, which is why we evaluate roofing, chimney, and siding as a connected system.
We frequently see:
Warped vinyl siding
Improperly sealed window trim
Moisture intrusion behind panels
Separation at seams
Storm-related impact damage
Moisture intrusion is one of the most common exterior issues in Washington County.
Most policies cover sudden storm-related damage, such as wind or fallen debris. Gradual wear or neglect is typically not covered. A documented inspection helps support claims when damage is storm-related.
Yes. We serve established neighborhoods and newer subdivisions throughout Hillsboro. Many newer homes are approaching the point where initial roofing systems benefit from inspection and maintenance.
Immediately
Even small leaks can damage insulation, drywall, framing, and create mold conditions if left unresolved. Early action reduces repair cost and protects your home’s structural integrity.
