New Hampshire weather can be tough on your roof. Between heavy snow, ice dams, wind, and summer storms, even a well-built roofing system can take a beating. When damage happens, one of the most common questions we hear at Ed Cyr Roofing is simple: Can this be repaired, or do I need a full replacement? The answer often depends on what we call the 25% rule.
What Is the 25% Rule?
The 25% rule is a general building code guideline stating that if more than 25% of a roof’s surface is damaged within a 12-month period, a full replacement may be required rather than partial repairs. While specifics can vary by municipality, the purpose of the rule is to maintain the structural integrity and performance of the entire roofing system.
In other words, once damage reaches a certain point, patching sections may no longer be the safest or most cost-effective solution.
Why This Rule Protects Homeowners
At first, replacing an entire roof can feel like a big step. Many homeowners understandably hope that targeted NH roof repair will solve the issue. In many cases, it absolutely can. Minor storm damage, isolated leaks, or a few missing shingles are often repairable.
However, when more than a quarter of the roof is compromised, ongoing repairs can lead to:
- Uneven aging across the roof
- Increased risk of recurring leaks
- Weakened underlayment or decking
- Higher long-term costs
How Roofing Damage Is Assessed
Determining whether your roof has crossed the 25% threshold requires a thorough inspection. Damage is not always obvious from the ground. Curling shingles, granule loss, soft spots, flashing failure, and hidden moisture intrusion all factor into the equation. At Ed Cyr Roofing, we carefully evaluate the entire roofing system, not just the most visible problem areas. Our goal is to provide honest feedback so you understand whether NH roof repair is sufficient or if replacement is the smarter long-term investment.
The Role of Insurance
After a major storm, insurance companies often assess the percentage of roof damage to determine coverage. If more than 25% of the roof has been affected by a covered event, a full replacement may be approved. Working with an experienced roofing professional ensures the damage is properly documented and clearly communicated. Accurate measurements and detailed reporting can significantly improve the claims process.
