Commercial roofs in Sherman do not get replaced because they wore out. They get replaced because nobody was tracking them. Banner Roofing & Construction provides commercial roofing for residential, commercial and multifamily property in Sherman, Texas — the Grayson County seat, north on US-75 in Grayson County. We are a veteran-owned, GAF Master Elite contractor working the historic downtown square and the older residential streets around it and the surrounding area. Free inspection, written scope, no obligation.
What Commercial Roofing in Sherman includes
A low-slope roof on a Sherman building rarely fails all at once. It fails at details, and it tells you well in advance if anyone is looking.
- Parapet, curb and penetration flashing
- Phased scope built around occupancy
- Low-slope and modified-bitumen systems
- TPO and single-ply membrane
- Metal roof systems and retrofit
- Steep-slope commercial and mixed-use
What to watch for
These are the conditions that most often bring Sherman property owners to us for Commercial Roofing. Any one of them is worth a look before it becomes the expensive version of itself.
- No documented roof condition report on file
- A roof approaching or past its warranty term
- Recurring leaks in the same tenant area
- Ponding water still standing more than two days after rain
- Seam separation, blistering or membrane shrinkage
Local conditions in Sherman
Older Sherman commercial buildings often carry layered roof systems and original parapet detail, so we core-test before recommending an approach.
Established Sherman commercial property tends to be on its second or third roof system, and knowing what is underneath changes the recommendation entirely.
Open Sherman exposure puts real uplift load on membrane edges and perimeter flashing — that is where low-slope systems in this market fail first.
Our order of operations
Three words govern how we assess a Sherman roof: repair, maintain, replace. In that order, every time. If the smallest fix will hold, that is what we scope. If maintenance gets you another six years, we will tell you how many. Replacement is the last answer, not the first pitch.
Credentials that actually matter
We are a veteran-owned team serving North Texas, holding GAF Master Elite certification, RCAT License 03-0562, NRCA and NTRCA membership, HUB certification and BBB accreditation. For Sherman property owners the practical difference is warranty coverage a non-certified contractor cannot register, and a company that is still here when you need that warranty.
How a Sherman project runs
We start with an assessment — a full walk of the property, photographs of every condition that matters and a written scope you keep whether or not you hire us. If you move forward, you get a firm schedule, a named point of contact and daily site protection. When the work is finished we walk it with you, clean the site completely and hand over the documentation and warranty paperwork.
Serving Grayson County and beyond
We are not a Sherman-only outfit — Banner covers Grayson County and the wider North Texas market, so the same crew and the same documentation follow you across the metroplex.

Yes. Our asset-management program covers scheduled inspection, documentation and prioritized repair across tiers.
What systems do you install?
Modified bitumen, TPO and single-ply, metal, and steep-slope architectural systems on mixed-use buildings.
