After a long West Michigan winter, May is the month to give your roof a clean bill of health before summer storms. Here’s a practical checklist our team uses across Holland, Zeeland, and the Lakeshore.

Shingles & Flashing

Look for lifted tabs, missing granules, cracked sealant, and gaps around chimneys, skylights, and step flashing. If you see multiple “bald” shingles or widespread lift, it may be time for a roof replacement; isolated issues often qualify for roof repair.

Attic & Ventilation

From inside the attic, check for daylight at the ridge/eaves, damp insulation, or musty odors. Proper intake/exhaust ventilation helps shingles last longer and reduces cooling costs. If your attic runs hot in July, ask about ridge vents and baffles during a free assessment.

Algae, Moss, and Tree Debris

Gloeocapsa (black streaks) and moss hold moisture against shingles. Gentle cleaning and zinc strips can help; never pressure-wash asphalt shingles.

Hail & Wind from Spring Fronts

Dings in soft metals (vents, gutters) often signal shingle bruising. Photograph what you see and call a pro before filing insurance.

Gutters & Downspouts

Clear winter grit and spring blossoms. If water overshoots 5″ K-style gutters, consider upsizing to 6″ or adding an extra downspout—our gutter repair team can evaluate.
