I have a 14 year old house in Tucson Arizona with a flat roof, and it needs significant work done. It has a built up roof right now, and there is significant buckling visible. I have been having repeated problems with leaking along the inside edges of the exterior walls especially near Downspout areas for the life of the roof… Some of this may be related to the fact that the original roof was not installed properly (they ran the sheeting up the inside of the parapet, but did not bring it over the top before capping :roll: Great huh?) At first it leaked along the entire permitter of the house, but another company came out and did some sort of seal on it that took care of most of the problems… except at some of the downspouts which seem to need work about every year or 2.
I just got 2 quotes from the same company on repairing it. One for stripping it and redoing the built up roof, and the other for Duro-last. The difference in price is significant ($11,000 for built-up, and $26,000+ for Duro-last). At the time that the inspection was being done the person pushed pretty strong for the duro-last, basically saying that it would be pretty much maintenance free, cut down on my heating and cooling bills, and would solve all of my leaky roof woes.
I have nothing against a really great roof that has a warrantee, low maintenance, and better R factor, but Does Duro-last really deliver on that promise to the tune of an additional 16 grand?
Would a properly done Built up roof give me similar performance ? (I know that I would have to have the white coating redone every 2 years or so). All of the leaks in the past have been at the edges near the down spouts, we have never had a leak near the interior of the house, so I think that it is a pretty good roof as far as pooling and stuff like that.
What do you think?
Also, are there other roofing options that I should consider?
BTY, the exterior walls are Stabilized Adobe construction if that makes a difference.
