Why Marathon Plus AR Fits DFW Roofs

We only spec three-tab in DFW for rental turns, detached structures and matching repairs on an existing three-tab roof. On a hail-exposed primary residence the 60 mph wind warranty and thinner mat make it a poor value against an architectural shingle — most carriers now scope architectural anyway.

How ADC Installs Marathon Plus AR

Standard four-nail pattern. Keep courses tight — three-tab is unforgiving of crooked lines. Match existing exposure exactly when doing a repair tie-in.

Marathon Plus AR — Frequently Asked Questions

Q.Should I put three-tab shingles on my Texas home?

Rarely. For a primary residence the architectural upgrade costs modestly more and doubles the wind warranty and expected life. Three-tab makes sense on rentals, garages and repair matches.

Q.Will insurance pay for an upgrade from three-tab?

Carriers pay to replace like for like. If your existing roof is three-tab, the upgrade difference to architectural or Class 4 is typically the homeowner's cost — we show it as a clear line item.
