I live in the mountains and my house is surrounded by huge Ponderosa Pines. The long pine needles that shed onto my roof are creating a problem with clogging up my gutter system and the resultant rainfall pouring off of my roof onto areas where it causes other problems. Can someone suggest a good brand of guards that can repel pine needles ? I don't have any deciduous trees close enough to the roof to have problems with regular leaves. My gutters look like the standard aluminum type and my roofer said If I can source the guards that I want and get them delivered he will come by and do the installation.
