Modified bitumen (mod-bit) is asphalt roofing engineered for low slopes: multi-ply redundancy and a puncture toughness single-ply membranes cannot match.
Modified bitumen argues its case with layers. Two or more plies of polymer-modified asphalt give a Frisco building a roof with backup, so a puncture has to beat redundancy instead of a single membrane. It handles rooftop foot traffic well, which suits roofs that double as equipment yards, and modern cold-applied and self-adhered systems have retired most of the old torch-down fire concerns.
We quote free and in writing and back each inspection with photos. We never waive deductibles, in line with Texas law, and we do not serve as a public adjuster.
Multi-Ply Protection for Frisco Commercial Roofs
Redundancy earns its keep under Frisco hail. The area within 8 miles has seen 22 days of golf-ball-size hail or larger since 2006, and a 4.5-inch stone fell on March 24, 2019. When a cap sheet takes a hit, the ply beneath still stands between the storm and the building, which gives an owner time to schedule a proper repair instead of chasing an active leak.
We walk and photograph mod-bit roofs after significant storms so any damage is recorded while it is fresh, with extra attention around equipment where crews walk. Frisco is a young Collin County city by housing measures, with only 2 percent of homes older than 1980. We run the same mod-bit work in Plano and Prosper.

How old Frisco homes are
Frisco is young by roofing standards: the median home was built in 2009, and 47% of its 80,353 housing units date to 2010 or later. Many of those homes still have the roof the builder installed, now working through its first hail seasons.

Common questions about modified bitumen roofing in Frisco
Is torch-down roofing safe?
Modern mod-bit rarely needs torches, since cold-applied adhesives and self-adhered sheets install without open flame. Where torch application is used, certified crews and fire-watch protocols are non-negotiable.
When does mod-bit beat single-ply in Frisco?
Heavy rooftop traffic and equipment service. The multi-ply build tolerates the abuse that punctures single membranes. Buildings whose roofs are working platforms are mod-bit's home field.
Is upgrading from builder-grade shingles worth it in Frisco?
Usually at the first replacement or claim: Class 4 impact-rated systems earn many Texas carriers' premium discounts, and newer communities' HOA standards generally approve them easily. The math works hardest on homes facing decades of DFW hail.
How often does hail hit Frisco?
NOAA's Storm Events Database lists 47 days since 2006 with hail one inch or larger reported within 8 miles of Frisco, including 22 days with golf ball size stones or bigger. Hail that size was reported in 15 of the last 20 years. The most recent report was 2-inch hail on June 2, 2026.
How old are most homes in Frisco?
The median home in Frisco was built in 2009, according to the U.S. Census Bureau's American Community Survey. 2% of the city's housing units predate 1980 and 47% were built in 2010 or later. Many homes here still have their original builder-installed roof.
