Commercial Roofing Dallas: Repair, Replace or Coat a Roof

Send us the building address and what the roof is doing. If a provider covers your address, your request goes to one independent partner, who contacts you within 24 to 48 hours.

Dallas Roof Works is a referral service, not the roofer. This page is for facilities managers, property owners and business owners. It covers the roof types on a bid. It also covers what to do when a flat roof leaks over an occupied building, and what to put in your request.

If the roof is leaking now

Protect people and stock first, then record what you see.

Keep staff and tenants off the roof and away from a sagging ceiling, and from water near lights or outlets.
Move inventory, files and equipment out from under the drip. Set a bucket, and cone off the wet floor.
Take dated photos of the stain, the ceiling around it and any drains you can see from a safe spot.
Write down when it started and whether it leaks only in rain.
Tell the tenant or site contact, and open a work order so there is one record of the date.

If anyone is in danger, call 911 first.

Water can travel along the roof deck before it drips, so the stain may not sit under the damage. Photograph the whole area, not only the wet spot.

Does the roof carry a maker's guarantee? Read its leak steps today. Johns Manville, a roofing maker, tells owners to report a leak within 30 days of finding it. Have the guarantee number, the location, how to reach the roof and a site contact ready.

Commercial roof types in plain terms

Most commercial roofs are low-slope, which means a slope of 3:12 or less (3 inches of rise over 12 inches of run). People call them flat roofs. The waterproof top layer is the membrane. Flashing is the metal and sheet material that seals the roof at walls, edges, pipes and rooftop units. Rooftop units (RTUs) are the heating and cooling units on the roof.

TPO. A single-ply sheet, typically white, with seams joined by heat welding.
EPDM. A single-ply sheet joined at the seams with tape.
Modified bitumen. Asphalt blended with polymers to stay flexible in cold and stable in heat, installed in sheets.
Built-up roofing (BUR). A layered asphalt system.
Metal. Panels over the structure. Ask what the seams and fasteners are, and how each is checked.
Coatings. A protective layer applied over an existing roof instead of tearing it off. Whether a roof can take one depends on the roof underneath.

Not sure which one you have? Send photos and the address. The provider can name it when they look.

Kitchen exhaust matters on some roofs. Carlisle, a membrane maker, says not to exhaust animal fats or vegetable oils onto EPDM. On TPO and PVC, it says to remove them regularly and clean the surface with soap and water.

Inspections and the roof file

Makers set their own schedules, so read the one for your roof. Two examples from owner's manuals:

Carlisle recommends an inspection every six months, preferably spring and fall, and right after weather with heavy rain, high wind or hail warnings. It also asks for one after any service on a rooftop unit.
Johns Manville recommends servicing twice a year, in spring and fall.

Both makers ask owners to keep records. Carlisle lists the warranty document and serial number, inspection logs, rooftop traffic logs, service logs and invoices. It recommends restricting roof access and keeping a log of who goes up. Johns Manville adds that the file helps a new owner if you sell.

Ask any provider for a written service report with dated photos after each visit. It shows what failed and what was repaired.

Check drains and low spots too. Carlisle says ponded water should evaporate within 48 to 72 hours after rain, and that debris can block drainage.

Johns Manville shows why records matter. It offers a five-year extension of certain guarantees, and it requires an annual maintenance and inspection agreement, with the contractor documenting each inspection. The extension is not open to coating systems. Your maker's rules may differ, so read yours.

Repair, replace or coat: questions that decide it

No single rule tells you when to replace. Put these questions to the provider and ask for answers in writing:

Where is the water getting in, and how was that found? Ask to see photos.
How many times has this area been patched? A repeat leak at the same spot points to a bigger decision than another patch.
Is the material under the membrane wet, and how was that checked?
What is the plan for the building: a sale, a refinance, a lease, or ten more years of ownership?
If a coating is on the table, what does the roof underneath need first, and does the maker's paperwork allow it?
If replacement is on the table, what does the scope include: tear-off or recover over the old roof, insulation, drains, flashing and rooftop-unit curbs?

If your roof is under a maker's warranty, check who may do repairs. Carlisle says its authorized applicators must perform revision work to keep the warranty in place.

Work around tenants and operations

Roof work has to fit the building's schedule. Raise these before work starts:

Roof access: hatch, ladder or stairs, and who holds the key.
Rooftop units: who services them, and whether they stay running.
Work hours, noise and what tenants need to be told.
Parking, staging and delivery space.
Walkways: Carlisle says walkways are needed where regular foot traffic is expected.

Ask for the plan in writing, with a name and phone number for the person on site.

Several buildings

Send each address in one request. Add the roof type, the age if you know it, and any open leak. We confirm coverage address by address. Ask the provider how they handle more than one site and how they report on each building.

What to put in your request

The building address, and the other addresses if there is more than one.
What the roof is doing: leak, stain, ponding, storm damage or an inspection request.
Roof type, if you know it.
Photos, with dates.
Any maker's guarantee, and where the paperwork is.
How to reach the roof, and who to call on site.
Your timing: a lease, a sale, a budget meeting.

How a request works

Send the address and what you see. Add the photos if you have them.
We check coverage for your address. We take requests in Dallas and the surrounding area, and we confirm your address first.
Our independent partner contacts you within 24 to 48 hours. They carry insurance and hold what the work requires. They look at the roof, then give you the scope, price, schedule and terms in writing.

The provider does the work and owns those terms. The roof decides the price, so this site posts none. Read the terms before you say yes, and see our referral disclosure.

Texas has no statewide roofing license, and the Texas Department of Licensing and Regulation (TDLR) lists no roofing program. Ask for a certificate of insurance, the written scope and price, and who issues any warranty.

Questions property teams ask

How much does a commercial roof repair cost?
The provider prices it after looking at the roof and gives you the number in writing.

Is it better to repair or replace a flat roof?
It depends on where the water gets in, how often the area has been patched and the condition of the roof around it. The questions above help you compare bids line by line.

How long does a commercial flat roof last?
It depends on the system, how it was installed and how it has been looked after. Ask the provider and the maker for the written term, and keep the service file current.

Can every commercial roof be coated?
No. The roof underneath decides. Ask the provider what it needs first and whether the maker's paperwork allows a coating.

Will an inspection tell me what my warranty needs?
Your warranty document and the maker set those terms. Keep the document in the roof file and send the provider a copy.

Can you handle one building or several?
Send every address in one request. We confirm coverage for each address, and the provider tells you how they work across sites.

Are you the roofer?
No. Dallas Roof Works refers each request to one independent partner, who does the work.
