How Long Does a Shingle Roof Last in Maryland?

What Can Damage Your Shingle Roof


Under normal conditions, rain damage to a properly installed and well-maintained roof is rare. However, issues can arise if water drainage is hindered, such as when leaves accumulate in roof valleys. It’s essential to clean your roof and gutters during the fall to prevent standing water, which can erode roofing materials over time. Prompt repairs are crucial to address any drainage problems and prevent potential issues.


Large hail can pose a threat to various roofing materials, including wood shakes, slate, and metal. While many shingles can handle normal hail impact, exceptionally large hail from heavy storms can lead to problems. It’s important to assess and address any hail damage promptly to ensure the longevity of your roof.

Snow and Ice

In cold climates, snow and ice can potentially damage roofs. While snow typically melts off without causing harm, underlying leaks may worsen as the snow exposes the roof to moisture. It’s advisable to fix any known issues before winter to prevent water damage during the spring melt. Regular roof inspections are crucial to maintaining its integrity in cold climates.

Moss and Algae

Moss on roof shingles can retain excess moisture, potentially causing damage. Removal using a bleach and water mixture, or careful brushing is recommended. Although moss is often superficial, it should be inspected by a professional if there are concerns about potential roof damage or leaks.


Wildlife, such as squirrels, birds, and raccoons, can create problems for your roof. Nesting in spring and shelter-seeking in fall are common issues. Additionally, animals may leave debris on the roof, contributing to potential damage. Regular roof maintenance and prompt removal of debris can mitigate these issues.

Signs You Need to Replace Your Shingle Roof

Curling Shingles

Curling shingles, either on edges (cupping) or in the middle (clawing), indicate potential roof issues. Warped shingles can lead to leaks and other property damage. Timely replacement is crucial once curling is observed. Consulting a roofing professional ensures an accurate assessment and necessary repairs or replacements.

Sagging Roof

Sagging spots on the roof signal weakened decking, the support structure for the roof. This can result from moisture, particularly in northern climates with harsh winters. Ice dams forming at the roof’s edge can hinder proper snow drainage, compromising the roof’s structural integrity. Immediate replacement is necessary for sagging roofs to avoid further damage.

Visible Leaks

Leaks are a clear indication that your roof may need replacement. Whether caused by worn-out materials or storm damage, leaks can lead to water intrusion and visible damage in the attic or interior walls. Small leaks can be repaired, but larger ones may necessitate a complete roof replacement.

Cracked or Missing Shingles

Inspect your roof for cracked, missing, or damaged shingles, especially after extreme weather events. Ice dams, in particular, can cause damage to shingles. While a few damaged shingles can often be repaired, widespread damage may require a full roof replacement.

Missing Granules

Weather and time can cause shingles to lose granules, leading to patchy or bare spots. Granules provide protection for the roof, and their loss accelerates roof decay. If granules are missing, a roof replacement may be necessary to ensure the roof’s longevity.

How Often Should a Roof Be Replaced?

The lifespan of a shingle roof depends on factors such as materials and installation quality. Most roofs are designed to last between 15 and 25 years. As a roof approaches the end of its lifespan, it becomes more susceptible to damage, necessitating more frequent repairs. If your roof is nearing the end of its expected lifespan, consider planning for a replacement to avoid costly and potentially dangerous issues.
