Why Tacoma homes need serious skylight attention
Skylights light up Pacific Northwest homes in a way regular windows can’t. But in Tacoma, where annual rainfall hovers around 38–40 inches and winter wind-driven storms are common, a skylight is only as good as its flashing and seals. I’ve walked more than a few shingle roofs in Tacoma, WA where a beautiful skylight was undermined by a dollar’s worth of failed caulk or a poorly lapped flashing kit. The lesson? Skylights aren’t passive features. They need proper installation, periodic leak testing, and timely flashing upgrades to withstand our climate.
Whether you’re calling a Skylight contractor Tacoma, WA for an inspection or your trusted Roofing contractor Tacoma, WA for a broader checkup, you want a pro who knows how Tacoma weather stresses roofing components. The best contractors also coordinate with a Gutter cleaning service Tacoma, WA to keep water moving, and an Insulation contractor Tacoma, WA to control condensation from the inside. That systems thinking prevents stains on drywall, swollen trim, and the dreaded musty smell that hints at hidden water damage.
Skylight leaks: symptoms, causes, and what to check first
How do you know if your skylight is leaking? Look for these signs:
- Brown “coffee” stains or soft spots on the ceiling near the skylight well. Drips during wind-driven rain, but not during light showers. Condensation between panes on older, failed-insulated-glass units. Damp insulation or musty odor within the shaft.
Common causes in Tacoma include brittle rubber gaskets from UV exposure, broken shingles around the curb, clogged gutters backing water under the flashing, and incorrect step flashing sequencing. I’ve also seen leaks caused by interior moisture rising into an uninsulated skylight well, then condensing and mimicking an exterior leak. That’s why a reputable Roofing company Tacoma, WA will test from both the exterior and interior before prescribing fixes.
Professional leak testing: how pros isolate the problem
A thorough skylight leak test is methodical. We don’t just spray and pray. Here’s the sequence I use https://www.buildzoom.com/contractor/pierce-roof-pros-llc on a shingle roof Tacoma, WA homeowners would recognize:
Visual survey: check shingles, step flashing, head flashing, sidewall transitions, and sealant at the glass-to-frame interface. Photograph everything. Interior baseline: moisture meter readings in drywall and framing. If numbers exceed 16–18% in wood, we flag it. Controlled hose test: start low on the roof, two feet below the skylight, and work upward. Keep the stream steady for 5–10 minutes per zone. When water appears inside, the last zone tells you where the failure sits. Smoke or tracer dye (when needed): helpful for hidden pathways or complex roof-to-wall junctions.Two quick pro tips: never direct water at the skylight glazing seals during testing until you’ve ruled out roofing and flashing. And always verify gutters are clear; an overflowing gutter can drive water sideways under shingles and make a skylight look guilty. Coordinating with a Gutter cleaning service Tacoma, WA before testing saves time and money.
Flashing upgrades that actually stop leaks
When leak testing points to flashing, upgrading is often the smartest move. Modern skylight flashing kits are engineered to shed water with generous overlaps that respect shingle exposure. On shingle roofing Tacoma, WA homes typically have, I recommend the following:
- Step flashing that interlaces with every shingle course along the skylight sides. A continuous head flashing at the upslope side with at least 4 inches of vertical coverage. A wide sill flashing or apron with a flexible underlayment membrane extending past the curb corners. Ice and water shield membrane wrapping the curb and extending 12–18 inches onto the field shingles.
If your skylight is older than 15–20 years, pair the flashing upgrade with a new unit. Today’s low-E, argon-filled glazing reduces heat loss and lowers condensation risk. When a Skylight contractor Tacoma, WA suggests full replacement rather than a band-aid, it’s usually because the frame and seals have reached the end of their service life. It costs more up front, but it’s cheaper than paying for interior drywall repairs every winter.
Shingle roof considerations in Tacoma’s wet season
For shingle roofing Tacoma, WA weather adds two stresses: wind-driven rain and moss growth. Both can undermine the water-shedding intent of flashing. During any skylight work on a shingle roof Tacoma, WA pros also:
- Replace brittle, cupped, or cracked shingles around the skylight curb. Install a high-quality underlayment that self-seals around nails. Detail the uphill side meticulously, where water loads are highest. Apply zinc or copper control strips above the skylight to discourage moss.
I’ve seen many “leaks” where flashing was fine but moss bridged the shingle laps and wicked water sideways. A short maintenance visit each fall prevents that problem and extends the life of both shingles and skylights.
Condensation versus leaks: how to tell and what to do
Is water on your skylight from a roof leak or interior condensation? Ask three quick questions:
- Does it appear after showers or cooking and clear on dry days? Likely condensation. Is the drywall damp in winter but not in summer? Condensation is a suspect. Do you see moisture between the glass panes? That’s failed glazing, not flashing.
Solutions include tightening the air seal of the skylight shaft, adding insulation around the well, improving bathroom and kitchen ventilation, and upgrading to better glazing. Partnering with an Insulation contractor Tacoma, WA to air-seal and insulate the shaft can drop surface humidity enough to stop “mystery leaks.” If damage has already occurred, a Water damage restoration service Tacoma, WA can dry, sanitize, and restore finishes before mold sets in.

Costs, timelines, and what to expect on site
Ballpark numbers vary by skylight size, roof pitch, and access, but here’s a realistic Tacoma range:
- Leak test and inspection: 150–350 dollars, often credited toward repairs. Flashing-only upgrade on a standard curb-mounted unit: 600–1,200 dollars. Full skylight replacement with new flashing on a shingle roof: 1,200–2,500 dollars per unit, higher for large or custom wells.
Most flashing upgrades wrap in a day. Full replacements take 1–2 days including interior touch-ups. Crews cover the skylight opening during work, protect furnishings below, and haul away debris. If rot is found at the curb or decking, expect an extra few hundred dollars and a couple of additional hours to make it right. A seasoned crew from a reputable Roofing company Tacoma, WA will brief you before they open the roof so there are no surprises.
Maintenance checklist to prevent future leaks
Preventive care beats emergency buckets every time. Add these tasks to your seasonal list:
- Clean gutters and downspouts twice a year to reduce backflow into flashing. Have a pro inspect skylight flashing and shingles annually, especially after severe wind events. Treat roof moss proactively and trim overhanging branches. Verify attic ventilation and air seal the skylight shaft to reduce condensation. Repaint the skylight well with moisture-resistant paint if prior stains occurred.
If you’re already scheduling roof work, ask for a skylight tune-up at the same time. Firms like Pierce Roof Pros bundle these services so you get better pricing and a coordinated plan.
FAQs: quick answers homeowners want
Can a skylight be repaired without replacing it?
Yes, if the glass and frame are sound. Reflashing, resealing, and adding membrane protection often solve leaks. If the glazing seal is failed or the frame is warped, replacement is smarter.
How long does skylight flashing last in Tacoma?
Typically 15–25 years depending on exposure, roof pitch, and maintenance. South- and west-facing slopes weather faster.
Will new flashing void my roof warranty?
Not when installed by a licensed Roofing contractor Tacoma, WA following manufacturer specifications. Make sure permits and documentation are in order.
Is condensation a sign of a roof leak?
Not necessarily. Condensation points to humidity and temperature differences. Improve ventilation, insulate the shaft, and consider upgrading glazing.
Who should handle interior repairs after a leak?
Once the roof is watertight, a Water damage restoration service Tacoma, WA can dry and sanitize. Your roofing or skylight contractor may coordinate drywall and paint touch-ups.
