The answer to 'gutter buildup' is that it is a common problem caused by leaves, twigs, and other debris accumulating in the gutters over time. Symptoms include water overflowing the gutters during rain, gutters sagging or pulling away from the roof, and even pests nesting in the buildup. The solution is to regularly clean out the gutters to prevent this buildup.
Homeowners can often handle gutter cleaning as a DIY task, but it's important to take safety precautions like using a sturdy ladder and avoiding working in wet or icy conditions. For taller homes or extensive gutter buildup, it's best to call in a professional gutter cleaning service to ensure the job is done safely and thoroughly.
