8 Signs You Should Call Kornerstone

Just like any part of your house, your roof isn’t immune to wear and tear. Over time, it can develop issues that may require the expertise of a professional roofing contractor. Ignoring these problems can lead to more significant and costly damage down the road. In this blog post, we’ll discuss some telltale signs that it may be time to call a professional roofing contractor.

1. Leaks and Water Stains

If you notice water stains on your ceiling or walls or if you experience leaks during heavy rainfall, it’s a clear indication that your roof is compromised. Leaks can result from damaged shingles, worn-out flashing, or even structural issues. Immediate attention is necessary to prevent further water damage, mold growth, and structural deterioration.

2. Missing, Damaged, or Curling Shingles

Shingles play a crucial role in protecting your roof from moisture and debris. If you see missing or damaged shingles, it’s a sign that your roof’s protective barrier is compromised. Additionally, shingles that are curling or buckling indicate aging and wear. A professional roofing contractor can inspect your roof, replace damaged shingles, and ensure your roof remains watertight.

3. Granules in Gutters

Asphalt shingles contain granules that protect them from the sun’s harmful UV rays. If you find an excessive amount of granules in your gutters or scattered on your property, it’s a sign that your shingles are deteriorating. This can lead to reduced roof lifespan and decreased protection. A roofing professional can assess the extent of the damage and advise on necessary repairs or replacement.

4. Sagging Roof

A sagging roof is a severe structural issue that requires immediate attention. It can be caused by various factors, including water damage, rotting wood, or improper construction. A professional roofing contractor will assess the situation, identify the root cause, and provide a solution to restore your roof’s integrity.

5. Mold and Moss Growth

The presence of mold or moss on your roof can be indicative of moisture problems. Mold and moss can weaken your roofing materials and lead to rotting and decay. A roofing professional can safely remove these growths and address the underlying moisture issues to prevent further damage.

6. Energy Bill Increase

If you’ve noticed a significant increase in your energy bills, it could be related to your roof’s insulation. Damaged or deteriorating roofing materials can allow air to escape, forcing your heating or cooling system to work harder. A professional roofing contractor can evaluate your roof’s insulation and recommend improvements to make your home more energy-efficient.

7. Age of Your Roof

Even if you don’t notice any visible problems, the age of your roof is a critical factor. Most roofing materials have a limited lifespan, typically between 20 to 30 years. If your roof is approaching or has exceeded its expected lifespan, it’s wise to have a professional inspection. They can advise on whether it’s time for a roof replacement to avoid unexpected issues and potential damage.

8. Pests and Critters

Roofs with cracks or holes can become an entry point for pests and critters. Squirrels, birds, and rodents may take advantage of these openings to nest in your attic or create further damage. A roofing contractor can identify and repair these openings to keep unwanted guests out.

Changing Customer Service

The roofing industry isn’t exactly known for being warm and fuzzy. This can result in homeowners feeling hesitant to ask the questions they need to know. At Kornerstone, we believe that you are entitled to feel informed and empowered when it comes to your roof. That’s why you can count on us to deliver exceptional service. In addition to clear communication, we offer flexible financing packages that allow you to care for your roof with ease. .

Frequently Asked Questions

Do I need a roof repair or full replacement?
