Low-slope roofs on the Gulf Coast fail at the edges and the equipment curbs. League City writes uplift detailing into its own code — 100 pounds, Inland I, stainless or galvanised.

Single-ply and modified systems specified for the exposure rather than the catalogue. On a 120 mph Inland I building the attachment pattern and perimeter enhancement matter more than the membrane brand does.
Low-slope roofs fail at the edges first, and a coastal wind event finds the corner zones before it finds the field. Fastening density in the perimeter and corner zones is where a commercial spec is won or lost here.
League City writes equipment uplift into its own ordinance — 100 pounds to Inland I standards with galvanised or stainless hardware, and pads at finished floor level or base flood elevation plus 24 inches in flood zones. HVAC curbs are a leak source and a compliance item at the same time.
Gulf Coast rainfall plus a flat roof plus a blocked scupper is how a deck gets overloaded. Drainage is assessed as part of the scope rather than treated as somebody else’s trade.
Commercial remodels in League City require the signature of the owner or the space lessee. On a leased building that means establishing early who is actually authorised to sign, which is not always who called us.
A scheduled inspection and repair programme on a low-slope roof costs a fraction of the replacement it defers. We would rather sell you six years of maintenance than a membrane you did not need yet.
What is actually on the deck, how many layers, whether the insulation is wet, and what the substrate will take. Photographed and written up so you can hand it to a lender, a buyer or a board.
Membrane choice, insulation, attachment pattern and perimeter enhancement specified to the Inland I exposure and to what the building actually does — a warehouse and a medical suite are not the same roof.
Commercial re-roof permit at $150, doubled if work starts first, with the owner or lessee signature the city requires. Windstorm applicability is established before anything is torn off.
Sections sequenced so the business keeps running, with nightly tie-ins that are genuinely watertight rather than optimistic. Gulf Coast afternoons do not forgive an open deck.
The default for new and replacement low-slope work here, and a reflective surface is worth having in this climate. Attachment pattern is specified to the wind zone, not to the brochure.
Where a roof takes foot traffic, equipment service or abuse, a two-ply modified system buys durability that a thin single-ply will not.
On the right building this is the sixty-year answer, and on the coast the fastener metallurgy and coating selection matter as much as the panel.
Written warranty on the installation itself, separate from whatever the membrane manufacturer offers.
NDL and system warranties available on qualifying assemblies installed by an approved applicator to the published specification.
Where the scope triggers it, the TDI process is carried through rather than left for you to discover at renewal.

Frequently yes. The windstorm rules define “construction” to include reroofing, and Galveston County sits inside the designated catastrophe area. Whether your particular scope triggers the certificate depends on the work, and we establish it before the tear-off rather than after.
League City writes it into the ordinance: pads at finished floor level, or base flood elevation plus 24 inches in flood zones, with windstorm uplift requirements of 100 pounds to Inland I standards using galvanised or stainless hardware. The ordinance uses TDI’s own zone terminology, which tells you how seriously the city takes it.
The city requires the signature of the owner or the space lessee on commercial remodels. On a multi-tenant building that is worth establishing on day one, because the person who calls a roofer is often not the person authorised to sign for the work.
$150, with the city’s fee schedule stating that any work done without a permit is subject to double the permit cost. Contractors also register annually at $150 with a $250,000 insurance minimum naming the City of League City as certificate holder.
It depends on what the roof has to survive. TPO is the default for most low-slope work here and the reflective surface earns its keep in this climate. Where a roof takes regular foot traffic or equipment service, a two-ply modified system buys redundancy that a single membrane does not. We will tell you which your building actually needs.
Sometimes, and we take core samples to find out rather than guessing. If the insulation is wet or there are already multiple layers, a re-cover buys you a shorter life and a warranty nobody will honour. The cores tell us, and we show you the results.
Yes, and on a low-slope roof it is usually the better value. Scheduled inspection, flashing and curb maintenance and prompt small repairs will defer a replacement by years at a fraction of the cost. We would rather have that contract than sell you a membrane before you need one.
Less than most owners expect, if it is sequenced properly. We phase the roof in sections so the building keeps operating, and every day ends with a genuine watertight tie-in — which on this coast is not optional, because the afternoon storm does not care about the schedule.
Free inspection, honest scope, real warranty. Most service work scheduled within 24–48 hours.
