The International Residential Code (IRC) updates for roofing this year include changes focused on improving safety, durability, and energy efficiency. One of the key updates is the increased emphasis on wind resistance, especially for homes in hurricane- or storm-prone areas. This includes stricter nailing patterns and requirements for underlayment materials designed to prevent wind-driven rain from entering the roof system. Another important update addresses ventilation standards, ensuring that attics and roof assemblies have proper airflow to reduce moisture buildup and prevent premature deterioration of roofing materials. Additionally, new provisions affect flashing around roof projections such as chimneys and skylights, requiring more robust installation techniques to keep water out. These changes are made to improve the long-term performance of roofs and reduce costly repairs due to water infiltration or wind damage.
For homeowners doing safe DIY checks, it’s wise to inspect your roof for signs of proper flashing, intact shingles, and clear attic ventilation without stepping onto the roof if you're unsure. Inside, check for any signs of water stains, mold, or visible daylight through the roof deck in the attic—these can signal improper installation or failing components. When it comes to calling a roofer, reach out if you notice loose shingles, damaged flashing, or water intrusion problems, especially after strong winds or storms. When consulting a contractor, ask if their work complies with the latest IRC standards and how they ensure proper ventilation and wind resistance. Also, inquire about any warranties they offer and how they handle failures related to these new code requirements to protect your investment effectively.
