What Is The 25% Rule For Roofing?

When it comes to roofing, many homeowners and business owners find themselves overwhelmed by the myriad of rules, regulations, and jargon that accompany such a significant investment.

The 25% rule for roofing essentially states that if you need to replace more than 25% of your roof's surface area due to damage or wear and tear, it's generally advisable to replace the entire roof rather than just patching up the affected sections.

  • Structural Integrity: A roof's ability to withstand weather conditions relies heavily on its uniformity. If only part of it is replaced, you may inadvertently weaken the structure.
