At BC Exteriors, we know how important a well-maintained roof is to your home or business. A roof leak can quickly escalate from a minor annoyance to a major problem, leading to structural damage, mold growth, and costly repairs. As Michigan’s trusted roofing experts, we’re here to help you understand the most common causes of roof leaks so you can keep your property safe and dry.
If you’re dealing with a roof leak, or simply want to take preventative action, this guide will explain the main culprits behind roof leaks and why regular inspections and maintenance are essential.
- Damaged or Missing Shingles
Shingles are your roof’s first line of defense against rain, snow, and wind. Over time, weather conditions, falling debris, or even simple wear and tear can cause shingles to crack, curl, or go missing entirely. Damaged or missing shingles leave your roof vulnerable to leaks, allowing water to penetrate the underlying layers and make its way inside.
As roofing specialists, BC Exteriors recommends regular inspections, especially after storms. Catching damaged shingles early can prevent water from entering your home or business and save you from a larger repair bill down the line.
- Clogged Gutters
Clogged gutters may seem like a minor issue, but they can lead to major roof leaks if left unaddressed. When gutters are filled with leaves, dirt, and debris, water can’t flow properly. Instead, it may pool on your roof or overflow, seeping into areas it shouldn’t—like under shingles or around flashing. This can lead to leaks, rotting wood, and damage to your home’s foundation.
Regular gutter cleaning and maintenance can prevent clogs and allow water to flow away from your property. At BC Exteriors, we also recommend installing gutter guards to help keep your gutters clear, reducing the risk of water damage.
- Improperly Installed or Damaged Flashing
Flashing is the thin metal or sealant placed around joints, vents, chimneys, and skylights on your roof. It acts as a sealant, directing water away from these vulnerable areas. If flashing is damaged, missing, or improperly installed, water can seep into your roof’s structure and cause leaks.
Over time, flashing can deteriorate due to exposure to extreme weather, or it can become loose from wind or ice. At BC Exteriors, we ensure that flashing is installed correctly and remains secure. During our inspections, we pay special attention to flashing around all roof penetrations to prevent water from entering your home or business.
- Poor Roof Ventilation
Ventilation plays a critical role in extending the life of your roof and preventing leaks. When a roof is poorly ventilated, moisture can build up in the attic, creating a humid environment that damages roofing materials from the inside out. This can lead to mold growth, wood rot, and even shingle damage, eventually causing leaks.
Our team at BC Exteriors assesses your attic’s ventilation system to ensure it’s allowing air to circulate properly, reducing the risk of moisture buildup. Proper ventilation not only prevents leaks but also keeps your home or business more energy-efficient.
- Ice Dams
Michigan winters bring freezing temperatures, heavy snowfall, and ice, which can wreak havoc on roofs. One of the most common winter issues we see at BC Exteriors is ice dams. Ice dams form when snow on your roof melts, runs down to the colder eaves, and refreezes. This ice buildup prevents additional snowmelt from draining properly, forcing water under your shingles and into your roof’s structure.
Ice dams can cause significant damage, leading to leaks and even structural problems. Preventing ice dams involves proper insulation, ventilation, and sometimes the installation of heat cables along the roof’s edge. We can help you take proactive steps to protect your roof from ice dams, reducing the risk of winter leaks.
- Aging Roof Materials
Roofs don’t last forever. Over time, materials naturally degrade, losing their ability to protect your property from the elements. As shingles, flashing, and other components age, they become more susceptible to cracking, curling, and leaking.
If your roof is 20 years or older, it may be time to consider a replacement or at least a thorough inspection. At BC Exteriors, we specialize in assessing the condition of aging roofs and can provide expert advice on whether a repair or replacement is the best option to keep your home or business leak-free.
- Cracked or Improperly Sealed Skylights
Skylights are a beautiful way to bring natural light into your home, but they can be a common source of roof leaks if they’re not sealed properly. Over time, the sealant around skylights can crack, allowing water to seep in. Additionally, debris buildup around skylights can cause water to pool, leading to leaks.
Our team at BC Exteriors inspects skylights carefully to ensure they’re properly sealed and installed. If you notice condensation or water stains around a skylight, it’s a good idea to have it checked to prevent further damage.
- Chimney Leaks
Chimneys are another vulnerable spot for leaks. Over time, the flashing around a chimney can wear down or become loose, creating a pathway for water to enter. Additionally, cracks in the chimney’s bricks or mortar can allow water to seep in, especially during heavy rain or snow.
At BC Exteriors, we provide thorough inspections around chimneys to ensure that flashing is intact and bricks are sealed against moisture. By taking care of any issues early, we help prevent leaks and protect your roof from further damage.
- Neglecting Regular Roof Maintenance
One of the most common causes of roof leaks is simply a lack of regular maintenance. Small issues like loose shingles, minor flashing damage, or clogged gutters can go unnoticed until they become major problems. Regular inspections and maintenance can catch these issues early, allowing for quick, affordable repairs before they turn into costly leaks.
At BC Exteriors, we offer routine maintenance and inspections to keep your roof in top shape year-round. With Michigan’s unpredictable weather, proactive maintenance is the best way to avoid unexpected leaks and extend the life of your roof.
