FAQs
What are the most common reasons flashing starts leaking on homes in Hillsboro?
In Hillsboro’s wet, windy climate, metal flashing can deteriorate faster than in drier areas. The main culprits are (1) corrosion from constant moisture, (2) wind-driven rain that works under poorly seated flashing, (3) thermal expansion and contraction that loosens nails or screws, and (4) improper installation of step or counter-flashing around chimneys, skylights, and wall intersections. Once gaps form, water follows the flashing and seeps into the roof deck and attic.
How can I tell whether I need a simple flashing repair or a full roof replacement?
A quick repair makes sense when the roof is fairly young (under 10–12 years for asphalt shingles) and the damage is confined to one or two flashing locations. However, if you see widespread shingle curling, granule loss, soft or sagging decking, or multiple areas where flashing has failed, a roof replacement is more economical long-term. Our Hillsboro inspectors use moisture meters and attic inspections to gauge hidden water damage before advising on the best option.
Will my homeowner’s insurance cover the cost of replacing a roof that’s leaking because of failed flashing?
Insurers in Oregon typically cover sudden, accidental damage such as wind-blown flashing failure, but they exclude problems caused by age or lack of maintenance. We document the roof condition with photos, a written inspection report, and a repair vs. replacement estimate so you can submit a strong claim. If coverage is denied, we’ll explain financing and rebate options from Energy Trust of Oregon for installing code-compliant, energy-efficient roofing.
How long does a Hillsboro roof replacement take, and will rain delay the project?
A typical single-family roof (2,000–3,000 sq ft) takes 1–2 days for tear-off and 1–2 days for installing new underlayment, flashing, and shingles—about 3–4 working days total. Because Hillsboro weather is unpredictable, we use breathable synthetic underlayment that can be exposed for up to six months and schedule work in phases to minimize open-roof time. If heavy rain moves in unexpectedly, we secure the roof with tarps and return as soon as conditions allow.
Do I need a permit to replace my roof or install new flashing in Hillsboro?
Yes. Washington County requires a residential reroof permit when replacing more than 30 percent of the roof covering or altering structural components, which includes new flashing installations. We handle the paperwork, fees, and mandatory inspections. Once the project passes final inspection, you’ll receive a completion card—useful for future home sale disclosures.
What warranty do you offer on new flashing and roof replacements?
All roof replacements come with a dual warranty: (1) a 50-year manufacturer’s limited lifetime warranty on shingles and factory-made flashing, and (2) our own 10-year workmanship warranty that covers installation-related leaks, fastener issues, and flashing failures. Because we’re an Owens Corning Preferred Contractor, your manufacturer warranty is registered automatically, and it’s transferable if you sell your Hillsboro home within the first 20 years.
