Modified bitumen systems are generally used on flat roofing and provide UV protection for long term performance. A modified APP system utilizes a top ply of modified membrane with one layer or two layers of base sheet. This system is usually torch applied granular surface matching to shingles or white for high reflectivity but self-adhered available when appropriate.
To Whom it May Concern:
I have been asked by Matteo Gutters to provide a recommendation.
Matteo Gutters provided extensive work at my home. They were thorough and timely, and I found their price to be very competitive. Of equal importance, they were sensitive to various design elements and were willing to make changes throughout the job to accommodate these revisions. They were cautious of the landscaping and surrounding areas and careful, each day to pick up their tools and debris.
Matteo Gutters did a terrific job. I couldn't recommend anyone more highly.
