Safety is the most important factor in DIY roof leak repair. Always wear proper safety gear, such as gloves, non-slip shoes, and a helmet, to protect yourself. Make sure your ladder is securely positioned on stable ground before climbing. Work with caution, especially near electrical systems or weak areas of the roof. Avoid working in bad weather, as wet surfaces can be slippery and dangerous. Simple repairs like resealing flashing or replacing broken shingles can help prevent further water damage. Take your time to inspect the roof properly before making any fixes. If the damage is severe, consider calling a professional for help.
