What to Do When a Skylight Is Leaking

Chelsey Smith • August 28, 2024

A leaking skylight can quickly turn from a minor annoyance into a significant problem for homeowners. Left unchecked, it can lead to water damage, mold growth, and even structural issues. Understanding the importance of skylight maintenance and knowing how to address leaks promptly is crucial for protecting your home. In this blog, we’ll walk you through everything you need to know, from identifying a leak to preventing future occurrences.

1. Identifying a Skylight Leak

Before you can address a leaking skylight, you need to identify the source of the problem. Common signs of a skylight leak include:

  • Water stains on the ceiling or walls near the skylight
  • Dripping water during or after a rainstorm
  • Condensation on the skylight glass

Check both the interior and exterior of your skylight. Look for cracks in the glass, gaps in the sealant, or damaged flashing. A thorough inspection will help you pinpoint the exact cause of the leak.


2. Immediate Actions to Prevent Further Damage

Once you've identified a skylight leak, take immediate action to prevent further damage to your home. Here are some steps you can follow:

  • Place a bucket or container under the leak to catch dripping water.
  • Use towels or rags to absorb any water that has accumulated.
  • If possible, cover the skylight with a tarp to stop additional water from entering your home.

These temporary measures can help you manage the situation while you determine the best course of action for repair.


3. DIY Solutions for Minor Skylight Leaks

For minor leaks, there are some DIY solutions you can try before calling in a professional:

  • Resealing the Skylight: Apply a high-quality silicone caulk around the edges of the skylight where the leak is occurring. Ensure the area is clean and dry before applying the caulk.
  • Replacing Damaged Flashing: If the flashing around the skylight is damaged, you can replace it yourself. Carefully remove the old flashing and install new flashing, making sure it fits snugly against the roof and skylight.

These fixes can often resolve minor leaks and save you the cost of professional repairs.


4. When to Call a Professional Roofer

In some cases, the leak may be too severe for a DIY fix, or you might feel uncomfortable attempting the repair yourself. Here’s when it’s best to call a professional roofer:

  • If you notice significant water damage to your ceiling or walls.
  • If the skylight glass is cracked or broken.
  • If you’ve attempted DIY repairs without success.

Professional Hamitlon roofers, at The Roofing Crew, have the expertise and equipment to handle more complex skylight issues. They can provide a thorough inspection, identify underlying problems, and ensure a long-lasting repair.


5. Preventing Future Skylight Leaks Through Regular Maintenance

Regular maintenance is key to preventing future skylight leaks. Here are some tips to keep your skylights in good condition:

  • Regular Inspections: Check your skylights at least twice a year for any signs of wear and tear. Pay special attention to the seals and flashing.
  • Clean the Skylight: Remove debris such as leaves, dirt, and twigs from around the skylight. This helps prevent blockages and water buildup.
  • Check for Condensation: If you notice condensation inside the skylight, it may indicate poor ventilation or insulation. Address these issues to prevent moisture buildup.

By staying on top of maintenance, you can extend the life of your skylights and avoid costly repairs.


A leaking skylight can be a homeowner’s nightmare, but with prompt action and regular maintenance, you can protect your home from damage. Start by identifying the source of the leak, take immediate steps to prevent further damage, and try DIY repairs if possible. If the leak persists, don’t hesitate to call a professional Hamilton roofer at  The Roofing Crew. Remember, consistent maintenance is your best defense against future leaks. Keep your skylights in top shape and enjoy the natural light they bring to your home without worry.

By Dawn Sherwin • December 9, 2024
Choosing the right roofing shingles for a row of townhomes can be a challenging task. Homeowners, property managers, and real estate investors must consider durability, energy efficiency, aesthetics, and cost-effectiveness. In this guide, we'll explore some of the best options available and how they can meet your needs. Why Choosing the Right Shingles Matters Roofing is not just about aesthetics; it's a vital component of your home's protection against environmental elements. With the right shingles, you can ensure longevity, reduce maintenance costs, and even improve the energy efficiency of your townhomes. Durability is Key For long-lasting protection, durable shingles are crucial. The Roofing Crew in Hamilton offers a variety of options that are known for their sturdiness. Asphalt shingles, particularly architectural ones, provide excellent protection against wind and weather while offering a classic look. Metal shingles are another durable option, with the added benefit of being fire-resistant and lightweight. Energy-Efficient Shingle Choices Energy-efficient shingles can help reduce heating and cooling costs, making them ideal for townhomes. Cool roofing shingles, which are designed to reflect more sunlight and absorb less heat, are an excellent choice. Products like Owens Corning’s Duration COOL Shingles can enhance your property's energy efficiency and potentially qualify for local rebates or tax credits. Aesthetic Appeal Matters When it comes to a row of townhomes, the visual harmony of the roofline is important. Architectural shingles offer a variety of colors and textures, allowing for personalization without compromising on quality. Consider choosing shingles that complement the exterior color palette of your townhomes for a cohesive look. Cost-Effective Solutions While you want durability and aesthetics, cost is always a consideration. Asphalt shingles are typically the most cost-effective option, providing a balance between price and performance. Fiber cement shingles, while slightly more expensive, offer longevity and require less maintenance over time. Making the Right Decision When selecting the best shingles for your townhomes, consider the local climate, your budget, and the architectural style of the buildings. It may also be beneficial to consult with professionals like The Roofing Crew in Hamilton, who can provide insights tailored to your specific needs.
