Seasonal Weather Patterns in Granada Hills

Granada Hills, California experiences a warm Mediterranean climate with dry, sunny summers and mild, rainy winters — a combination that can gradually wear on gutters and exterior systems if not maintained year-round. In winter (December–February), most of the area’s annual rainfall arrives, often through strong storms that can quickly expose gutter blockages or weak seams. Overflowing gutters during these downpours can lead to fascia rot, roofline leaks, or foundation pooling if water isn’t properly redirected. Spring (March–May) brings lighter rain, steady breezes, and pollen-heavy air from surrounding oak and citrus trees. This combination causes fine debris and leaves to collect in gutters, forming blockages that restrict drainage and trap moisture. During summer (June–August), Granada Hills turns hot and arid, with temperatures regularly climbing into the 90s. Though rain is rare, UV exposure and expansion from heat can weaken gutter joints and seals, while dust and ash from nearby canyons settle inside gutters, setting up future clogging issues. By fall (September–November), Santa Ana winds sweep through the San Fernando Valley, scattering leaves, branches, and dirt across rooftops and gutters. This buildup can quickly block downspouts just before winter rains return. While Granada Hills avoids snow and ice, the area’s cycle of heat, wind, debris, and sudden rainstorms makes consistent gutter cleaning, inspection, and sealing critical to prevent leaks, sagging, and costly home repairs.

Best Granada HIlls Gutter Company Services

John and his beautiful and well trained dog came for estimate and he had some great suggestions on where to add and subtract the downspouts. We have never done seamless gutters and they really are very beautiful. We went with a beautiful dark bronze which matches the house and our fascia boards perfectly. The crew did a great job. We will see how they work after some rain but John let me know that they could come back if there is an issue and modify if necessary. Great warranty by the company. Honestly, the dog was the best part. She really should be on your business card not gutters!

Over the years, my team and I have helped many homeowners and property managers in Granada Hills protect their homes from the toll our local weather takes on gutters. The area gets around 15 inches of rain per year, mostly between November and April, with the heaviest storms often hitting in February and March. Long, dry summers bake leaves, dirt, and debris into gutters, while the strong Santa Ana winds common in the foothills can clog systems overnight with oak and eucalyptus leaves. That combination of wind, heat, and seasonal rain makes seamless gutter installation and regular maintenance essential for keeping Granada Hills homes safe and water-damage free year-round.
