Navigating the myriad of myths surrounding roofing can be overwhelming for homeowners. This article aims to clarify common misconceptions and provide reliable, factual advice to help maintain the integrity and longevity of your roof.

Myth 1: Asphalt Shingles Are Low Quality

– Truth: Asphalt shingles are highly versatile and offer significant benefits in terms of cost-effectiveness and durability. Modern high-quality versions are designed to last 20-30 years and come in various styles to enhance aesthetic appeal, making them a practical choice for many homeowners.

Myth 2: More Insulation is Always Better

– Truth: While adequate insulation is crucial for energy efficiency, too much can trap moisture and lead to deterioration and mold. Proper ventilation should also be considered to balance the roof’s temperature and moisture levels.

Myth 3: A Leaky Roof Needs Complete Replacement

– Truth: Many leaks can be resolved with minor repairs, especially if the damage is localized and the roof structure remains sound. A professional evaluation can determine whether a repair or replacement is more appropriate.

Myth 4: It’s Okay to Layer New Shingles Over Old Ones

– Truth: While layering may seem like a cost-effective solution, it can conceal underlying damage and add undue stress to the roofing structure. Removing old shingles allows for a thorough inspection, ensuring a longer-lasting and safer roof.

Myth 5: You Can DIY Roof Installations

– Truth: Roof installation requires specific skills and adherence to building codes. DIY projects can lead to improper installation, increased risks, and voided warranties. Hiring a professional ensures the job is done safely and correctly.

Myth 6: All Roofing Contractors Are the Same

– Truth: The expertise and reliability of roofing contractors vary widely. Certified contractors, especially those recognized by reputable industry bodies, typically provide higher quality services and warranties, offering better overall value.


Dispelling these roofing myths is crucial for homeowners to make informed, effective decisions regarding their roof’s care and maintenance. By understanding the facts and seeking guidance from professionals like Three Mountain Roofing, homeowners can ensure their roof remains in optimal condition for years to come.
