Short Answer
A periodic inspection is prudent, particularly after severe weather and as the roof ages.
Detailed Explanation
Roof inspections should be performed periodically — typically annually for roofs in good condition, and more frequently as the roof ages or after severe weather events. A good schedule is: annual professional inspection, inspection after any significant storm (wind, hail, heavy snow), and more frequent inspections (every 6 months) for roofs over 15 years old. Spring and fall are good times for routine inspections — spring to check for winter damage, fall to prepare for winter. Homeowners can do visual checks from the ground (looking for missing or damaged shingles, sagging, debris), but a professional inspection includes attic examination, close-up roof assessment, flashing evaluation, and ventilation check. Regular inspections catch small problems before they become major leaks.
Why It Matters
Regular inspections catch problems early when they're inexpensive to repair. Neglecting inspections allows small problems to become major leaks.
