Hello! We have done quite a few re-roofs for TexAgs users. We can typically tear off the old roof and install new in one day (highly advisable with the unpredictable weather). We have never been called back about one of our roofs leaking. Would be happy to come out and meet you to give a free estimate. Please give us, Envision Renovations, a call at 713-425-3799. Also feel free to check out some of our recent work on Facebook or EnvisionYourHome.com. Thanks, Vince Grainger, Class of '08.
