Gutter & Valley Cleanout
Leaves and pine needles collect in valleys and behind chimneys, hold water, and wear out the shingles underneath. The contractor clears valleys and the roof surface by hand or with a blower, scoops the gutters, flushes the downspouts, and checks that water drains away from the foundation. Packed gutters can also back water up under the drip edge and rot the fascia.

Moss & Algae Soft Wash
A soft wash uses a diluted cleaning solution applied at garden-hose pressure, then lets it work instead of blasting the surface. Heavy moss is brushed off gently once it dies back. Shrubs below the eaves get rinsed and protected from runoff. Results on algae streaks often show over a few weeks of rain, not the same day.

Zinc or Copper Strips
After a cleaning, many owners add a strip of zinc or copper just below the ridge. Rain washes a small amount of metal ions down the roof, which discourages algae and moss. The effect weakens on long slopes, and they work better at prevention than at killing established moss. Algae-resistant shingles use a similar idea with copper-coated granules.

Flashing & Fastener Resealing
The factory-fresh sealant over exposed nails, vent flanges and counterflashing usually fails years before the shingles around it. The contractor scrapes off cracked old caulk, reseals with a roofing-grade sealant, resets backed-out nails, and replaces neoprene pipe boots that have split. Cracked boots are one of the most common sources of slow attic leaks.

Limb Trimming & Attic Checks
Overhanging limbs scuff the shingles, shed debris, shade the roof so moss grows, and give critters an easy way up. Many roofers trim small limbs back from the roofline and recommend an arborist for larger ones. Inside, they check that soffit vents are not blocked by insulation and that bath fans actually vent outdoors.

Maintenance Plans & Commercial Drains
Many independent roofers set up recurring visits, typically spring and fall, with a written condition report after each one. On low-slope commercial roofs, plans focus on clearing drains, scuppers and gutters so water does not pond, and on checking seams around rooftop units. Terms and pricing are set by the contractor, so read the plan agreement before signing.
