Hello, I hope to gain some insight as well on roofing. We are looking at replacing a 3 tab roof(leaking ceiling) with either the Malarkey Highlander or Pabco Premier 30. I have seen both and the noticeable differences are in 1. the thickness(Pabco is thicker) and 2. the pattern of the shingles; malarkeys pattern flares out(I'm told by the other guy this can cause needles to lodge in the crevises down the road) whereas Pabcos shingles wedge in,. Both have algae blocker. Pabco uses felt underlayment, Malarkey uses Nova Seal II /WaterBlock Ru 200. Now I understand that the Highlander does not contain the rubber like the Malarkey Legend shingle so I'm not sure what I'm comparing. All that I have read about Malarkey seems good,although there is alot of Malarkey marketing out there. ...no pun there. Any insight greatly appreciated.
