Did you know that the average house produces 5 gallons of water vapor EACH day? So your roofing underlayment not only needs to shed water, but also needs to be permeable. At Cenco Building Services, we use only the highest grade synthetic underlayment to both protect your roof and allow it to breath. And look! It doesn’t wrinkle under your shingles either!If you need a quality roof installed by trained, safe professionals, call Cenco Building Services today at (720)-582-1690 for a free replacement estimate.
