5 Common Roofing Mistakes You Need to Avoid



The ideal scenario for investing in a new roof is to consider it a single investment opportunity. Nevertheless, the challenge arises due to the concealed nature of essential elements in roof installation. While only the roof shingles are visible on the surface, depending exclusively on visual examination to evaluate the roof’s quality proves inadequate. This report seeks to shed light on common roofing mistakes and shortcuts frequently found during installations, enabling you to avoid such pitfalls effectively.

Installing a New Roof Over an Existing One

One common error many individuals make is placing a new roof over an existing one. In certain states, overlaying multiple times can be deemed illegal by law. Nonetheless, even if this practice is allowable in your region, refrain from it.

Your deck could be causing the leaks and other roofing issues you are encountering. The sole method to identify its weaknesses is to remove the old roof. Uncovering what lies beneath and rectifying any deck-related problems can ensure a thorough roof repair or replacement. Installing new shingles over old ones might damage your walls and roof further. Typically, this added layer increases weight, potentially straining your walls and roof structure.

Cheap Choices

While investing in new or replacement roofs may not come at a lower cost, there is a rationale behind this decision. Choosing a budget roof often equates to accepting subpar materials and craftsmanship. Some aspects of life demand unwavering quality, and your roof falls squarely into that category.

A less expensive roof is typically more prone to damage and deterioration, suggesting premature replacement is needed. To avoid this common misstep, direct your resources towards a top-notch product and a trustworthy company. However, this doesn’t mean you shouldn’t scout for competitive offers. Yet, if a quote appears exceptionally alluring, it is probably too good to be true. Choose the best roofing contractors, like ACME Roofing, for quality services and products at competitive prices.

Incorrect Use of Nails

Avoid using a few nails. Sufficient fasteners, placed correctly and at the right angles, are essential for securely fastening shingles, slates, or other roofing materials in place.


 Short nails may not effectively penetrate the roof’s underlayment, leading to inadequate security for the shingles or slate. This can result in nails popping up over time, creating openings for water to seep through during rainfall, potentially causing leaks.

Using Diverse Roofing Shingles

An often-seen error involves the utilization of mismatched asphalt shingles, resulting in a visually uneven and inconsistent roof. This issue commonly arises when roofers procure shingles from different suppliers without meticulous consideration of their compatibility during installation.

To avoid this issue, ensure that your roofing professionals use asphalt roofing materials from a consistent supplier for your project. If you have engaged a reputable contractor, this issue should not arise. However, it may pose a risk if you opt for a contractor prioritizing cost-cutting over quality.

Tasks for Maintenance and Repair that Have Experienced Delays

Irrespective of the quality or longevity of the construction materials, it is vital to prioritize roof inspections, continuous maintenance, and repairs. Failure to address roof damages promptly can lead to increased repair expenses as issues worsen. The repercussions also extend beyond just fixing the roof, as leaks can impact other household elements.


Delaying maintenance activities like replacing damaged shingles or rectifying leaks can gradually decline your home’s interior condition and structural stability over time.


Carrying out roof repairs or replacements requires significant skill and expertise. It is not a DIY home improvement project. Although trying to save money might seem appealing, even minor errors can escalate into significant issues.
