A commercial roof inspection in Allen produces a written, photo-documented report on the membrane, seams, flashings, penetrations, and drainage. That report is the document every repair, restore, or replace decision should start from, and it becomes the baseline your building’s maintenance and insurance files are built on. The inspection and any resulting estimate are free and in writing. If the findings point toward a claim, we stay on the construction side: we are not a public adjuster, and Texas law means no deductible gets waived.
Why Allen Buildings Need a Roof Baseline
A baseline is most useful where hail is frequent, and Allen qualifies. Within 6 miles of the city, 27 days since 2006 have produced hail an inch or larger, 12 of them at golf-ball size or above, with a peak stone of 4.5 inches on March 24, 2019. When a building has a dated inspection on file from before a storm, it is far easier to show an adjuster what changed.
Housing across Allen comes mostly from the 1980 to 2009 building period (66 percent) plus another 27 percent built in 2010 or later, and the commercial properties serving those neighborhoods often follow a similar timeline, so few owners have a roof history going back very far. We run inspections throughout Collin County, including Lucas and Plano.
