Frequently Asked Questions

How often should I have my roof inspected? 

It’s recommended that you have your roof professionally inspected at least once every 1-2 years and after any major storm or extreme weather event. Regular inspections can help catch minor issues before they become major problems, potentially saving you money on repairs in the long run. 

These check-ups allow professionals to identify and address small issues like loose shingles or minor leaks before they escalate into more significant and costly damages.

How long does a typical roof last? 

The lifespan of a roof depends on various factors, including the materials used and local climate conditions. On average, asphalt shingles typically last 20-30 years, while metal roofs can endure for 40-70 years. Tile and slate roofs are known for their longevity and can last over 100 years with proper maintenance. 

However, it’s important to note that regular maintenance and prompt repairs can help extend the life of your roof regardless of the material. Factors like extreme weather, poor ventilation, and inadequate maintenance can significantly reduce a roof’s lifespan, so proper care is vital.

Should you always replace your entire roof if you find a leak? 

Many leaks can be effectively repaired without replacing the entire roof, especially if your roof is relatively new and in good overall condition. The key is to have a professional roofer assess the situation. They can determine whether a targeted repair or a full replacement is the most appropriate and cost-effective solution.

Is it true that adding new shingles over old ones is just as effective as a full roof replacement?

This is a common misconception. While re-roofing can save money in the short term, it doesn’t address underlying issues with the roof deck or allow for a thorough inspection of the entire roofing system. 

A complete tear-off and replacement, though more expensive initially, allows for a comprehensive inspection and repair of any hidden damage. This approach typically results in a longer-lasting roof and is recommended by most experts for the best long-term results.
