sequence of roofing materials, for flat roof?

By LiamK

I’m a newbie, working on a shoe-string to gut and salvage the small 1950s house I inherited, but with no cash to “do it right.” It is either make-do, or lose the house. It will be torn down whenever it is sold, and a McMansion built.

I have a question on recommended roofing materials for the flat roof, and their sequence. The roof is flat and is 32 squares (including shop and carport), in the rainy Pacific Northwest. Does the following sequence make sense? Or is the sequence wrong? Can I cut anything, to save money? Anything I should add, like Tyvek/Typar — if so, where?? From the top down:

* membrane (probably PVC; or torchdown)
* #30 roofing felt
* peel-stick water-and-ice barrier [GAF or Grace or ??]
* [possibly 1″ XPS rigid foam insulation if I can afford it, to insulate and smooth any rough old deck; R5]
* old tongue-and-groove wood decking (on drip-edge replaced 4′ in, and as needed)
* 2″ airspace
* 5.5″ Roxul rock-wool insulation R22 [more mold-resistant than fiberglass]
* drywall ceiling (probably paperless-drywall, to limit mold; DensArmor or ??)
* latex paint (Kilz II primer)

It’s a very flat roof, a 1:16 slope (too flat) that leaked on and off for years, so there was a very serious mold problem (requiring a complete gut inside of all drywall and trim). I need to tear off layers of old build-up (hot-tar) roofing, and repair parts of the deck, and fix some joists/rafters that are rotted for 3′ on the drip-edge. I’ve read lots of debates about torchdown vs PVC membrane. I’m currently leaning towards PVC, despite the higher cost, as its safer for me to install myself (no flame), and white is better in summer (I’ve no A/C). I worry about condensation if I use PVC, though I’ll add at least two 2-way vents (kitchen and bath) and the soffits have vents.

I really appreciate any sound advice, especially from those who’ve been around long enough to see fads come-and-go. Many thanks in advance!

Upgrades to AER Respond Product Significantly Improve Hail Claim Assessments

LEXINGTON, Mass.–(BUSINESS WIRE)– Atmospheric and Environmental Research (AER), a member of the Verisk Analytics (NAS: VRSK) Family of Companies, today announced upgrades to its near-real-time AER RespondTM and historical AER BenchmarkTM products. The upgraded service provides a 15 percent improvement in the ability to validate hail claims.

“Until now, the fundamental gap in all radar interpretations of hail has been ground truth,” said Nicole Homeier, senior staff scientist at AER. “We’ve confirmed that insurance claims data, when considered carefully to avoid bias, has proven invaluable to validate radar-based hail data. Insurance claims data can also elevate the state-of-the-art of algorithms that predict the occurrence of claims and the resulting repairs.”

“We are thrilled to see continued investment by AER on this important topic for the insurance industry,” said Tim Reinhold, senior vice president of research and chief engineer at IBHS. “Increasing accuracy on where hail has occurred and how severe it was directly relates to IBHS‘ work to improve building standards and building component performance in hail-prone regions.”

AER leverages aggregated claims data provided by hundreds of property/casualty insurance carriers to Verisk Analytics.

“Three years ago, carriers approached AER with the request to improve the state of the art for the industry,” said Kyle Beatty, senior vice president of Business Solutions at AER. “It’s been satisfying to work with industry leaders in the insurance, manufacturing, and professional services sectors to transform the way cause‐of‐loss data is used in the insurance claims and restoration process.”

AER is an extended part of our team, pushing the boundaries of physical and data science approaches to improve the claims experience of our policyholders,” said Renee Beauford, vice president for Claim at Hastings Mutual Insurance Company. “Their commitment to transparency and their investment in long-term transformative solutions for our industry are exactly what we look for in our suppliers.”

“The combination of advanced weather content and insurance claims that AER has brought to market has created substantial value for GAF and our business partners,” said Randy Bargfrede, executive director of logistics and transportation for GAF. “AER‘s unique position in the industry can truly transform how wholesale and retail distributors look at weather’s effect on their businesses.”

AER‘s ability to translate the occurrence of hail to effects on our top line is providing us the opportunity to reduce the volatility of some of our revenue streams,” said Jay Huie, …read more
