    Flat roof repair

    Actually, the one quote I've gotten so far for whole-roof replacement is $9,100. Ouch. Not to mention almost a thousand dollars more than my neighbors paid to replace THEIR roof in the aftermath of Hurricane Wilma, when roofers could charge just about anything the insurance companies would bear...

    Worth insulating?

    97% of the motive for gutting and rebuilding the master bathroom is a major mold problem. Paper-backed drywall = mold food. Florida mold is like cancer... you can fight it aggressively by taking away its food & water and send it into remission, but you'll never be truly rid of it. You can burn...

    Worth insulating?

    I'm remodeling the master bathroom, and at the moment its ceiling has been completely removed, exposing the steel pan deck of the concrete suspended slab that forms the roof and temporarily giving me full access to the void between the ceiling drywall and pan deck for nearly the entire second...

    Flat roof repair

    My roof has more drama going on than Broadway. Out of the 3 roofers who were supposed to come give estimates today, only one showed up (I can't entirely blame the other two, though... we've had torrential downpours & thunderstorms all day, with a tornado watch from ~10am until mid-afternoon)...

    Flat roof repair

    Well, some bad news and awesome news. The bad news: I talked to someone at the building department. He's heard of Ames Super Elasto-Barrier, and thinks it's a wonderful product. Unfortunately, Ames never bothered to get "Dade County" approval for it, so it can't be used to satisfy code...

    Flat roof repair

    Well, I talked to the homeowner association's site manager on Saturday, and his opinion of elastomeric roof coatings was pretty high. He said that you basically need to re-coat them after every hurricane and every few years, but as long as you do that, they'll last indefinitely. The downside is...

    Flat roof repair

    Well, yesterday I spent a couple of hours up on the roof trying to patch the flashing with the obvious hole and two blisters. I came to the conclusion that there are SO MANY blisters up there, it would literally be easier to rip the entire upper layer off and replace it. Basically, every 3' x 3'...

    Flat roof repair

    I talked to someone about the roof at a party last night. He said you're right, but not with respect to South Florida. He wasn't sure whether it was merely a norm, or an outright HVHZ (high-velocity hurricane zone) building code requirement, but down here built up roofs are usually(always?)...

    Flat roof repair

    Well, the first roofer was just here. I haven't gotten a price quote yet, but here's what I found out: * My roof is absolutely, positively a 100% conventional oldschool hot-mopped built up roof. * The roofer didn't want to do a complete tear-off... partly because there's no logistically...

    Flat roof repair

    Hmmm. This is the first I've heard of it, but you might be right. I thought anything that involved a flat roof & asphalt-based products was a "Built Up Roof" (as opposed to SPF -- sprayed polyurethane foam, or single-layer PVC or rubber membranes). It makes sense, though... the neighbors' roofs...

    Flat roof repair

    I have a conventional built-up flat roof on a concrete deck with dozens of blisters, nearly every single seam in bad condition, and water infiltration at at least one (probably more) penetrations including the bathroom exhaust fan duct shown in the last two pics. As badly as I'd love to have it...

    Foam for flat roof - viable for residential use?

    Well, I just got back from Home Depot ~2 hours ago, after picking up a sweet St. Louis brand 24' 300#-capacity fiberglass extension ladder for $110 (closeout special). I went up on the roof again, was happy to see it looking a LOT drier than yesterday, and shot some new pics. The bad news is...

    Foam for flat roof - viable for residential use?

    I have a townhome whose roof is 18x44 feet. The roof deck itself is reinforced concrete, with built-up roof that's approximately 10 years old (according to the guy who sold the house to me last year). I've always had a major humidity problem (with 90pt/day whole-house dehu, I can get the house...
