Saving money with a better roof
Fall of 2008, Main Terminal Roof Complex: 374,804 sq.ft.
We coated the entire Tucson Airport complex of roofing in Tucson, Arizona.
The roofing is “cap sheet” which is tar paper and this requires SUPER BASE (HS) at 9 sq.m (100 sq.ft.) per gallon and then overcoated with SUPER THERM® at 9 sq.m (100 sq.ft.) per gallon.
Other parts of the roofing is PVC or a plastic type material which is weathered but is in good condition and provides good adhesion to accept SUPER THERM® easily at the 9 sq.m (100 sq.ft.) per gallon.
Preparation was the use of “Simple Green” concentrate cleaner and power wash. The roof was power washed to wet down, the simple green cleaner was sprayed over the roof and large hard bristled push brooms were used to clean the surface and then the power washer was used to rinse this all off before it dried. The power washer was working behind the push brooms to assure nothing dried before it could be washed off. When the roof surface dried, the SUPER BASE (HS) adhered very strongly and tightly to the surface.
With the total utility savings of $22,144 (22%) in August for the total facility and the A/C portion of the total utility being 55%, this relates to a 40% savings in A/C operational cost. The savings are beyond the A/C running cost, the units cycle less giving long life, less maintenance work and less tonnage to take care of the main terminal and wings.
The total roof area of the terminal is 374,804 sq.ft., at a cost of $2.10/sq.ft., for a total job cost of $787,008. With a cost reduction of $22,144 / month, it results in a 36 month return. If the savings is averaged at less at $15,000/month, the result is 52 months return.
No matter whether the return is calculated on 36 months or 52 months, this savings amount is now available to offset budget needs without the need to find new funding.
RENTAL CAR WASH BAYS:
The car wash bays were done first, and we had to remove the existing elastomeric coating which was not adhering, was not water proofing and was not insulating.
