Common Roofing Issues That Arise During Lansing's Hot and Humid Summers

Lansing summers bring plenty of sunshine, but they also usher in high humidity, intense heat, and sudden storms. This combination can be tough on your roof, especially if it's already aging or has existing vulnerabilities. Homeowners throughout the region often face a spike in roofing problems during the summer months, many of which can go unnoticed until they lead to serious damage.

Here are the most common roofing issues to watch out for during our hot and humid summers—and how you can protect your home with the help of Lansing's preferred roofing company.

1. Shingle Deterioration and Curling

Prolonged exposure to intense UV rays can bake asphalt shingles, causing them to dry out, become brittle, and eventually curl or crack. Once shingles are compromised, water can seep underneath, leading to leaks and interior damage. Lansing’s humidity doesn’t help either—moisture can get trapped under curled shingles, creating ideal conditions for rot and mold.

2. Heat-Related Expansion and Contraction

The summer heat can cause roofing materials to expand during the day and contract as temperatures cool at night. Over time, this cycle of movement can loosen flashing, fasteners, and seams, increasing the risk of leaks. Metal components, in particular, are vulnerable to warping and separation in extreme heat.

3. Algae and Mold Growth

High humidity levels in Lansing can create a perfect breeding ground for algae, moss, and mold—especially on north-facing or shaded sections of your roof. These growths are more than just an eyesore. They can retain moisture, degrade shingles, and shorten the lifespan of your roof. Regular inspections and cleanings are key to preventing long-term damage.

4. Ventilation Problems

A properly ventilated roof allows hot, moist air to escape from your attic, helping regulate indoor temperatures and protecting your roof from premature aging. When ventilation is poor, trapped heat can cause shingles to overheat and increase the risk of warping. Additionally, moisture buildup in the attic can lead to mold, wood rot, and higher energy bills.

5. Sudden Storm Damage

While summer in Lansing is known for heat and humidity, it’s also storm season. Heavy rain, hail, and high winds can tear off shingles, damage flashing, or knock debris onto your roof. What may start as a minor puncture or loosened material can quickly escalate if left unchecked.

6. Hidden Leaks and Water Damage

Hot weather doesn’t always dry things out. In fact, summer humidity can mask leaks as slow, hidden moisture buildup behind walls and ceilings. By the time you notice water spots or mold, the damage may already be extensive. That’s why it’s important to schedule regular roof inspections and prioritize roof repair before problems grow.
