During January, Portland roof repair calls spike, not because of dramatic weather events, but due to days or even weeks of steady rain. This saturation exposes hidden vulnerabilities that weren’t a problem during the dry season. We’ve compiled a short list of the most common issues we fix this time of year and what homeowners should know before scheduling repairs.
1. Flashing Failure Around Skylights and Dormers
Older Portland homes, especially Craftsman and mid-century designs, often feature decorative dormers and multiple skylights. These beautiful architectural features are common leak points in winter. As flashing lifts or deteriorates, water creeps behind the trim and into attic spaces.
Temporary Fix: Reseal or add a flashing patch
Permanent Fix: Replace surrounding flashing or components, and assess slope design
2. Wall-to-Roof Transitions
Many homes in Portland’s Eastside neighborhoods have complex roof lines with wall transitions. These areas collect water and debris. Over time, the caulking and step flashing degrade, allowing slow, persistent leaks behind the siding.
Temporary Fix: Clear debris and reseal edges
Permanent Fix: Replace flashing and ensure proper overlap
3. Leaks Near Plumbing Vents and Furnace Exhausts
It’s not unusual for homeowners to find leaks near vent pipes. The rubber or plastic boots used around these penetrations degrade from sun exposure and eventually crack.
Temporary Fix: Apply a rubber seal or flashing tape
Permanent Fix: Replace the boot and inspect all similar penetrations
4. Worn-Out Composition Shingles
In neighborhoods with 15–25-year-old roofs, we frequently find shingles that have started curling, cracking, or losing granules. These shingles don’t shed water efficiently and can allow leaks to form during heavy rain.
If your roof is nearing the end of its lifespan, short-term repairs may help, but a full replacement could be more cost-effective over time.

At Pacific West Roofing, we take a calm, inspection-first approach. Not every leak means disaster. Sometimes, a simple repair can restore your roof’s performance and buy you years of additional service. But if your system is showing widespread wear, we’ll give you honest advice about your long-term options.
