GREEN Medical Center Home For Sale: The Roof

3703 Drummond, Side Street View

This very GREEN home in Braes Heights near the Texas Medical Center, is for sale for $1,695,000.  It has many certifications, among them, a Fortified Rated Home.  For this designation, it must be able to withstand winds 20 mph higher than the wind speed FEMA gives for this location (110 mph).  The owner wanted a roof engineered to 130+ mph.  Replacing a roof is very expensive and removing an old roof puts a large truckload of composition shingles in the landfill, and it will take centuries to decompose.  This roof is warranted for 50 years.  The cost “makes sense”, because over the life of the roof, someone would have to replace a traditional roof at least 3 times

For an additional nominal cost (pennies/sq. ft.), the shingles became the primary water barrier, rather than roofing felt normally used.  To condense my information to the simplest terms, I will give you the layers from outside to inside the roof/attic assembly:

DECRA Shingle Plus roofing panels which are screwed into the battens, 8 screws/panel.  These are stone-coated horizontal metal roofing panels.  Note how attractive these are on this home.

2×2 treated battens that are screwed into the roof deck and rafters

TCM-4RW radiant barrier/vapor barrier

Grace Ice and Water Shield applied to the entire roof deck.

5/8″ roof decking that is independently screwed into the rafters

Rafters that are hurricane strapped to each other and then anchored to the ICF (insulated concrete form) wall system.

Icynene open-cell foam sprayed under the roof deck and covering all the wood elements of the roof assembly.

Entering this attic on a 104 degree day in August, you will experience a temperature that is within 3 degrees of the conditioned living space and only a fraction more humid.  This allows for very usable storage space, and most certainly, a longer life for the mechanical systems that have to live in the attic.

This next weekend hurricane season begins along the Gulf Coast, and in case of a storm coming, I think I would feel very safe and comfortable in the attic, as well as any room in this home.

Next posting will cover the windows, which also have strict guidelines for that Fortified Rating.
