Since starting full operations, the HAWC gamma-ray observatory has detected and monitored the high-energy TeV emission of the nearby BL Lac objects Markarian 421 and Markarian 501. HAWC performed a follow-up survey of Active Galactic Nuclei selected from the 3FHL Fermi Catalog covering 60% of the sky and up to redshift z<0.3. Using over 4.5 years of HAWC data we found low-significance evidence for persistent TeV emission from the radiogalaxy M87 and the BL Lac objects VER J0521+211 and 1ES 1215+303. We present here an update on the HAWC follow-up survey adding over a year of new HAWC data.
