Flat Roof Replacement in Van Alstyne from $350. Porches, additions and small commercial -- where the drainage decides everything. Free inspection and a written quote.
New construction flat sections are usually small, well detailed and sound -- so a leak on one is almost always a penetration that was sealed rather than flashed. That is a small fix, and it should not turn into a membrane replacement.
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. Nearly everything here is recent, so the cost driver is what the builder specified rather than what the roof has been through. A tract-standard three-tab and a Class 4 roof on identical houses are $3,000 apart and age identically differently.
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.
New housing means new roofs, which changes the likely answer. A leak on a roof under ten years old is almost always a detail or a workmanship issue -- a flashing, a penetration, a valley -- rather than age. Where hail is involved it is worth establishing whether the builder's shingle was Class 4 or the cheapest option.
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.
Nearly everything here is recent construction, which makes the useful question specific: what shingle did the builder actually fit? A tract-standard three-tab on a hail-exposed roof is a shorter life than the house has, and knowing that early turns a surprise into a plan..
New-build roofs are where this decision is most often made badly, because it was made by the builder rather than by you.
A new roof can absolutely be hail-damaged, and homeowners here frequently assume otherwise because the house is recent.
On a recent build the shingle is whatever the builder specified and the installation is whatever the crew did that week.
Worth checking before you commit: a lot of newer subdivisions have covenants about roofing materials and finishes, and metal is the one most likely to run into them.
The one place here with a City registration rule.
Older stock: board decking, valleys, dormers.
Splits by age. The newer roofs have seen hail already.
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.
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.
Get a second opinion before you sign anything, and ask whether they are registered with the City of Sherman. A hail line damages thousands of roofs in twenty minutes and brings out-of-town crews into the county for the season. Some are perfectly competent; the check costs you nothing and it is the only one available in a state with no license.
One to three days on site for a typical house, three to seven for metal, and one to two for a small simple roof. Weather moves all of it and we will not dry-in a roof we cannot finish. After a storm line the queue is the longer part rather than the work.
City of Sherman registration stated -- Texas issues no license. Standard and Class 4 priced side by side, not one of them.
