Exterior Services for Hillsboro's Rolling Terrain
Hillsboro is a growing city north of Beaverton with a strong sense of community identity. The city has experienced suburban expansion while maintaining a town-center character. Neighborhoods are well-established with tree-lined streets and single-family homes. Hillsboro attracts families seeking suburban living with good schools.
Community Overview
Population
106,000
Housing Stock
Predominantly single-family homes in planned neighborhoods. Mix of 1970s-1990s suburban construction and newer 2000s+ development. Many established homes (30-40 years old) are approaching major systems replacement. Lot sizes are moderate suburban. Tree coverage is significant, especially in older neighborhoods.
Weather Challenges in Hillsboro
- • Rolling terrain creates drainage challenges. Properties on slopes experience water runoff issues.
- • Rain exposure similar to Portland: 40+ inches annually. Gutters overflow frequently.
- • Older homes in established neighborhoods have poor drainage systems. Foundation moisture and basement seepage are common.
- • Tree coverage in older areas means shade and moisture. Moss on roofs is endemic.
- • Spring snowmelt in higher elevations can overwhelm drainage systems in some neighborhoods.
- • Wind-driven rain penetrates older siding and windows, causing interior moisture and potential mold.
Our Services for Hillsboro
Slope & Drainage Management
Hillsboro's rolling terrain requires careful grading and downspout placement. We design drainage solutions for sloped properties.
Moss Prevention
Zinc-infused shingles inhibit moss on new roofs. Pressure washing removes existing moss. Branch trimming improves airflow.
Complete Gutter Systems
Seamless gutters with guards handle heavy rainfall and leaf-drop. Proper sizing for drainage capacity is critical.
Roof Replacement
Many Hillsboro homes have 30-40 year old roofs. Replacement with premium moisture-resistant materials is due.
Foundation Drainage
Assess grading, landscape, and foundation systems. Correct water intrusion issues before interior damage worsens.

Frequently Asked Questions
Why does my Hillsboro home have water in the basement after rain?
Sloped terrain, poor grading, or insufficient downspout drainage. We assess your specific drainage system and recommend corrections (grading, downspout extension, french drains).
How do I prevent foundation moisture on a sloped lot?
Proper grading (slope away from house), extended downspouts (at least 6 feet), and potentially french drains. We design complete solutions for sloped properties.
Is moss on my roof a problem?
Eventually, yes. Moss holds moisture against shingles, accelerating deterioration. Pressure washing helps temporarily, but best solution is zinc-infused shingles on replacement.
How often should gutters be cleaned in Hillsboro?
Spring and fall minimum (quarterly in heavy-leaf areas). Gutter guards reduce to 1-2 times yearly. Clogged gutters cause overflow and basement moisture.
Should I worry about mold in my Hillsboro home?
Yes. Poor drainage, roof leaks, and moisture infiltration create mold risk. Proper gutters, grading, and roof maintenance prevent this. We assess mold risk during inspections.
