Flat Roof Replacement in Sherman from $350. Porches, additions and small commercial -- where the drainage decides everything. Free inspection and a written quote.
Low slope here is porches, rear additions, carport roofs and small commercial buildings. What fails is the outlet, the scupper, the parapet and the upstand rather than the middle of the membrane -- and Texas heat works every lap through a daily expansion cycle on top of that.
Low slope around here is porches, rear additions, carport roofs and small commercial buildings rather than whole houses. What fails on them is almost never the middle of the membrane: it is the outlet, the scupper, the parapet and the upstand where the covering turns up a wall.



Low slope here is porches, rear additions, carport roofs and small commercial rather than whole houses, so it is priced on the area and the number of details rather than from a table. What decides whether it lasts is almost never the membrane -- it is whether the water can leave. Locally the first question is not price at all, it is registration: Texas issues no roofing license, so a contractor's City of Sherman registration and the $300,000 liability cover behind it are the only formal credential there is. The permit is $75.
Standing water 48 hours after rain means the fall is wrong or the outlet is blocked. Texas heat then cooks a ponded membrane through a daily expansion cycle. Re-covering over it buys a couple of seasons.
A membrane can be holed by hail that would only bruise a shingle, and the puncture is small enough to go unnoticed until the insulation below is saturated. It is checked for specifically, not just looked over.
Because the ratio of perimeter detail to field is worse. A tiny porch roof is almost entirely edge, and edge is where the labor is.
Sherman is the one place on this list where the contractor question has a local answer. Roofing contractors must register with the City and carry $300,000 of liability cover naming it as certificate holder -- which is the checkable credential in a state that issues no roofing license at all. The permit is $75.
Texas licenses electricians and HVAC technicians and does not license roofers, so City of Sherman registration is the only formal credential this trade has here.
Texas heat is the local aggravator. A dark membrane in full sun runs hot enough to work every lap and every seam through a daily expansion cycle, and standing water accelerates it. So the drainage gets measured before a system is chosen, and where the fall was set wrong the honest answer is to correct it rather than re-cover over it.
It is the most common reassurance offered in this market and it is hollow by construction. Here is what to ask instead.
A roofing contractor working here must be registered with the City as a Roofing Contractor and must carry a $300,000 certificate of liability cover naming the City of Sherman as certificate holder. That is specific, local and checkable, and almost nobody asks about it.
It is what gets the work inspected, which is the only independent confirmation you will ever get that the specification you paid for is the one that went on. A contractor who would rather skip it is telling you something.
The Roofing Contractors Association of Texas runs a voluntary program. It is not a license and we will not pretend it is one -- but in a state that requires nothing, what somebody has volunteered for is more informative than what they were made to do.
Ask one question before you compare quotes here: are they registered with the City of Sherman as a Roofing Contractor, with the $300,000 liability cover naming the City as certificate holder? Texas issues no roofing license at all, so that registration is the only formal credential this trade has in this city.
Class 4 is the top UL 2218 impact rating -- a two-inch steel ball dropped twice on the same spot without cracking the mat -- and it installs at $500 to $750 per square in North Texas against $350 to $500 for three-tab.
Hail damage on asphalt is bruising rather than holes: the impact fractures the mat under the surface and knocks granules loose, leaving soft spots that age far faster than the rest of the slope.
Three-tab at $350 to $500 per square is the cheapest covering available and, on a hail-exposed Sherman roof, the shortest-lived.
Metal is priced on geometry rather than area: every valley, dormer and penetration is a detail formed by hand and the labor is most of the cost.
Older stock: board decking, valleys, dormers.
Splits by age. The newer roofs have seen hail already.
Almost all new build. What did the builder fit?
Metal country, and the two systems are not the same.
Lake exposure, and houses nobody is in to notice.
Small simple roofs. Price should track area here.
Acreage. The barn is usually the worse roof.
What is worth knowing before you book this.
Water still sitting 48 hours after rain means the fall is wrong or the outlet is blocked, and Texas heat then cooks a ponded membrane through a daily expansion cycle. It is not an emergency this week and it is what turns a membrane job into a deck replacement.
Yes, and that is the specific risk single-ply carries that a shingle does not. Hail that would only bruise asphalt can hole a membrane, and the hole is small enough to go unnoticed until the insulation below is saturated. It gets checked for specifically.
No. The Texas Department of Licensing and Regulation licenses electricians and HVAC technicians and does not license roofers, and no other state body does either. So a contractor telling you they are 'licensed in Texas' is describing something that does not exist. What does exist in Sherman is City registration as a Roofing Contractor, with a $300,000 certificate of liability cover naming the City.
Texas prices asphalt by the square -- a hundred square feet. Three-tab installs at $350 to $500 per square and Class 4 impact-resistant at $500 to $800, with North Texas typically $500 to $750 for Class 4. A 2,000 square foot roof is twenty squares. The Sherman permit is $75.
Not from the ground. Hail damage on asphalt is bruising -- the impact fractures the mat under the surface and knocks granules loose -- so it is felt rather than seen. Three pieces of evidence settle it: the slopes checked by hand, the soft metal (vents and flashings dent before shingles bruise), and granule loss in the gutters.
City of Sherman registration stated -- Texas issues no license. Standard and Class 4 priced side by side, not one of them.
