When sunny summer days stretch across the South Puget Sound, cleaning out gutters or inspecting roof flashing is usually the last thing on any homeowner’s mind. It is easy to look up at a clear sky and assume everything overhead is in top shape.
In the Pacific Northwest, dry summer months are the single best window you have to check your home’s exterior. Once the fall rains begin, minor issues like a loose shingle, baked-on moss, or a needle-filled downspout can quickly spiral into interior water damage, rotted fascia, and costly emergency repairs.
Here is a straightforward summer maintenance checklist to protect your home before the rain returns.
1. Inspect Your Shingles for Summer “Sun Bake” Damage
Our wet PNW winters get most of the blame for roof damage, but summer heatwaves take a heavy toll on asphalt shingles. Strong UV exposure bakes older shingles, making them brittle and prone to cracking.
- What to Look For:
- Granule loss – Bare spots or heavy black grit in gutters
- Curling & Buckling – Edges lifting upward due to heat or moisture
- Missing Shingles – High wind damage from late winter storms
-
Pro Tip: Start safely from the ground using a pair of binoculars. Scan the rooflines, paying extra attention to South-facing slopes that get direct sun exposure all day.
2. Check “The Big 3”: Flashing, Vents, and Chimneys
Water rarely penetrates right through the middle of a shingle. It almost always leaks through roof penetrations and seams. Summer is the ideal time to check these critical connection points while the surrounding materials are dry:
-
Flashing Gaps: Check the metal flashing around chimneys, skylights, and dormers. Look for cracked sealant, rust, or metal lifting away from the wall.
-
Vent Pipe Boots: The rubber boots surrounding your plumbing vent pipes dry out, crack, and fail over time. Replacing a dry-rotted boot during a dry spell costs very little, but a failed boot in November leads to water-stained ceiling drywall.
-
Roof Valleys: Leaves and pine needles gather where two roof planes meet. When left to sit, this organic debris traps moisture against the shingles.
3. Clear Out Pine Needles and Evergreen Debris
In neighborhoods across Puyallup, Tacoma, and Pierce County, majestic Douglas firs and Western Red Cedars drop immense amounts of needles and sap during warm, dry summer months.
-
Clear the Gutter System: Scoop out dried needle mats and seed pods before the first fall downpour packs them tightly into the downspout bends.
-
Flush with a Hose: After scooping out heavy debris, run a garden hose through the gutters to check the slope and flow. If water pools instead of draining toward downspouts, your gutter hangers may need tightening or re-pitching.
-
Extend Downspouts: Make sure downspout extensions release water at least 3 to 5 feet away from your home’s foundation.
4. Treat Moss Before the Fall Bloom
Moss thrives in our damp climate, but summer is the best time to stop it in its tracks. Dry summer moss is dormant and far easier to treat effectively.
-
Never High-Pressure Wash Asphalt Shingles: Blasting shingles with a high-pressure washer strips away the protective mineral granules and drastically shortens your roof’s lifespan.
-
Gently Brush and Treat: Use a soft-bristle brush to gently loosen thick moss clumps. Apply an eco-friendly moss control treatment formulated for PNW roofs to kill remaining spores before fall moisture wakes them back up.
5. Trim Back Overhanging Tree Branches
Shaded roofs stay wet longer, providing the ideal breeding ground for moss, lichen, and rot. Furthermore, heavy branches hanging over your home pose a serious storm hazard when winter windstorms hit.
-
Trim branches back so they sit at least 8 to 10 feet away from your roofline.
-
This improves sunlight exposure, accelerates roof drying after rain, and prevents squirrels and raccoons from using branches as a bridge onto your roof.
DIY vs. Calling a Local General Contractor
While checking gutters or clearing light debris from a low-pitch single-story roof can be a safe weekend DIY task, climbing steep slopes or working near tall eaves carries real risks.
A licensed local general contractor can perform a comprehensive roof and gutter check, identifying subtle issues like improper attic ventilation, hidden fascia rot, or failing flashing that an untrained eye might miss.
