How we work · Dallas-Fort Worth
A roof is three days of noise in your driveway, so here are the rules we run by.
Knox Roofing is a Dallas roofing contractor with its own sheet metal shop. This page is the part most roofing companies leave out: who is on your property, what gets covered before the first shingle comes off, who calls you at six in the evening, and the four jobs we will not take.

Who you are hiring
The name on the contract and the building it comes from
The operator of this site and the business you would be contracting with is Knoxroofingpros, trading as Knox Roofing at knoxroofingpros.org. It is a roofing contracting business: steep-slope and low-slope roofing plus sheet metal fabrication, working for homeowners, property managers, general contractors and building owners across Dallas-Fort Worth.
The office and the shop share one address, written out in full: 9659 Wendell Rd, Dallas, Texas 75243, United States. There is no second location and no franchise arrangement behind the name. When you call the number on this page, you are calling the building where the brake sits.
Some things you will not find on this site, because they are not ours to state: a founding year, a headcount, a license number, a star rating, a review count, an award or a manufacturer certification tier. Plenty of roofing sites in this metroplex publish all of that. We publish the material specifications, the method and the address, and you can judge those directly.

The argument
Most leaks we chase are not the shingles. They are a chimney somebody sealed with a tube of caulk in 2009.
Why the shop matters more than the brochure
The work itself
What this Dallas roofing contractor actually does
Three lines of work, and one of them is unusual for a roofing company this size.
Residential steep-slope. Architectural asphalt shingle, standing seam and exposed-fastener metal, clay and concrete tile, natural slate. Full tear-off to the deck, re-decking where the boards are soft, re-roof, repair, and hail and wind damage inspection. Specifications, weights and lead times for each of those are set out on the residential roofing page rather than summarised here.
Commercial low-slope. TPO at 60 and 80 mil, two-ply modified bitumen, silicone coatings over sound dry substrates, and metal roofs on warehouses, retail and churches. Core cuts before any number gets written. The commercial page carries the systems table and the probe-log routine.
Sheet metal fabrication, in house. We bend our own drip edge, step and counter flashing, chimney crickets, valley metal, gutters, coping caps and standing seam panels on our own brake, in 24-gauge Galvalume, painted steel or 16 oz copper. The piece gets made to fit your roof rather than caulked to fit a stock part. We also take fabrication orders from other trades, by the piece or the linear foot.
Nothing is priced on this website. Every job is quoted after a measured inspection, in writing, with the tear-off layers, the decking allowance per 4x8 sheet, the underlayment brand, the ventilation, the metal, the haul-off and the permit all listed as separate lines. If it is not on the paper, it is not in the price.
Site rules
What happens in your driveway, hour by hour
These are not aspirations. A foreman who skips one of them hears about it.
-
Tarps before tools
Shrubs, AC condensers, pool surfaces and anything on a patio get covered before the first shingle moves. Plywood over a glass table, not a tarp. The condenser coil gets a hard cover, because granules in a coil cost more to fix than the roof section above it.
-
Driveway, not the street
Dump trailer in the driveway with boards under the jack and the tongue so the concrete does not get scarred. If the drive will not take it, we park on the street and carry further. We do not block a neighbor's drive and we do not leave the trailer overnight on a Friday.
-
Start at seven thirty
Compressors do not run before 7:30am, and we stop nailing by dusk. If a neighbor works nights, tell us and we will start the loud end of the roof later.
-
Nothing open overnight
Whatever we tear off, we dry in the same day. Underlayment down and sealed before the crew leaves, every day, including the day the forecast says clear. Dallas forecasts are not a waterproofing system.
-
Magnet twice a day
Rolling magnet over the drive, the walks, the beds and the grass at midday and again before the crew leaves. Then again on the final walk. Nails find bicycle tires and dog paws faster than they find anything else.
-
One foreman, one number
The same foreman is on your roof from tear-off to final walk and his name is on your paperwork. You do not get handed to a different crew halfway through and you do not have to explain your roof to somebody new.
-
Photographs of what gets covered
Bad decking, a rotten fascia board, a vent that was never connected, a bathroom fan dumping into the attic: photographed next to a tape before it is covered, and the cost of fixing it told to you before we fix it. No surprise line items at the end.
-
Harnesses on anything steep
Fall protection on steep-slope work, period. It slows the crew down on a 10/12 and that is already in the price. Nobody free-climbs a tile roof to save forty minutes.
Communication
You should never have to chase us for an update
The complaint we hear most about other roofers is not workmanship. It is silence. Somebody signed a contract in April, the material was back-ordered, and nobody called to say so. So the rules on our side are blunt.
You get told the day before the crew arrives, and you get told again if weather moves it. On a residential tear-off, the foreman calls or texts at the end of each working day with what got done and what is next. On a commercial job, the daily photographs and the seam probe log go to whoever is paying, not just to the property manager who asked nicely.
If we find something that changes the price, the call happens before the work, not on the invoice. That means a phone call first, then the same thing in writing. A change order you learn about from a bill is a billing dispute we would rather not have.
If material slips, we say the new date and why. Clay tile matching and copper coil are the two things most likely to move; metal panels run in our own shop almost never do, which is part of why we run them ourselves.
Your estimate lists the underlayment by brand and the decking by the sheet. If it is not on the paper, it is not in the price.
The shop
Wendell Road: coil stock, a brake and a set of scribed measurements
Walk in the roll-up door and the first thing you see is coil on reels: 24-gauge Galvalume, painted steel in the standard color range, 16 oz copper. Behind that, the box-and-pan brake, a shear, a roll former for panel profiles, and a rack of finished work waiting to go on a truck. Drip edge in ten-foot lengths. Coping caps with their splice plates taped to them. A copper cricket for a chimney in Lakewood with its seams soldered rather than riveted and sealed.
This is the difference between a flashing detail that works and one that leaks in four years. A supply-house counter flashing comes in one size with one bend. A chimney is never that size. So the fabricator takes the field measure, draws the girth and the bends, cuts the coil and makes the piece, and the crew sets it into a ground-out mortar joint the same week. Where the wall leans, the metal leans with it.
Having the shop also means we are not waiting on a supplier mid-job. A valley metal piece cut two inches short at 10am is remade by 2pm. On a standing seam roof, panels are run to length, so a 38-foot slope goes on with no end lap anywhere in it, which is the joint that fails first on panel roofs installed from stock lengths.
Material gauges, lengths and shop turnaround times are listed on the commercial page.
On overlays
No overlays. Two layers of shingle in a Texas August is a griddle, and it hides the decking we need to see.
The first of four refusals
The refusals, at length
Four jobs we turn down, and the reason each one is a no
Three of these will be offered to you by somebody else this storm season. Knowing why they are a bad idea is worth more than a discount.
-
We will not lay a new roof over an old one
An overlay saves the tear-off line on the estimate and costs you the roof. Two layers of asphalt hold heat against the deck through a Dallas summer, so the new shingles age faster than the warranty assumes. The second layer never lies flat over the first, so the nail pattern is compromised and hail bruising is harder to read later. Worst of all, nobody can see the decking. Soft sheathing, a cracked rafter, a bathroom fan venting into the attic: all of it stays hidden under new shingles, and the first person to find it is whoever tears the roof off next. If an overlay is what you want priced, we are not the right contractor and we will say so on the phone rather than waste your afternoon.
-
We will not re-use old flashing on a full replacement
This is the single most common corner cut in this market, and it is the reason the leak comes back. The shingles are new, the step flashing at the wall is the same rusted pieces from 1998, bedded in fresh caulk. Caulk is a maintenance item, not a flashing. On a Knox tear-off every wall gets new step flashing with a kick-out at the bottom of the run, every chimney gets new counter flashing let into a ground-out mortar joint, every valley gets new metal, and all of it comes off our brake. If the estimate you are comparing does not list new metal by the linear foot, ask what happens to the old pieces.
-
We will not waive or absorb your deductible
In Texas, a contractor offering to cover, rebate or build your insurance deductible into the invoice is committing fraud and pulling you into it. It also means the number on the paper is inflated by exactly the amount being pretended away, so your carrier is being billed for work you did not pay for. We write the real price, you pay your deductible to us, and the claim paperwork says what actually happened. Anybody at your door offering otherwise is telling you how they handle paperwork in general.
-
We will not take a contingency agreement at your door after a storm
The day after hail, a line of trucks works the neighborhood with a clipboard and a one-page form that assigns your claim to whoever knocked first. We do not do that. We inspect the roof, write what we find, and you decide with the report in your hand and no signature attached to the inspection. If a company needs you to sign before it climbs the ladder, the signature is the product.
Fit
Who we are not the right call for
01
Lowest number wins
Our estimate carries lines that cheap bids leave off: new metal at every wall, decking by the sheet, ventilation, haul-off, permit. We will not strip them out to match a thinner bid. If price is the only axis, somebody else will win and you will probably see us in six years.
02
Patch it and sell it
If the goal is to get a roof past an inspection on a property you are offloading, we are a poor fit. We will repair honestly and we will document what is still wrong, and that document goes to you in writing.
03
Outside the metroplex
We work Dallas-Fort Worth. Call us about a roof in Houston and we will tell you to find somebody local rather than bill you for windshield time.
04
Tile with no structural check
Clay tile weighs 900 to 1,100 pounds a square. If you want tile on framing that was built for composition and you do not want anyone looking at the rafters first, that is a no.
Reaching a person
How to get hold of somebody who can answer
Call 214-646-6625. The phone rings at the office at 9659 Wendell Rd, Dallas, Texas 75243, and somebody there books inspections, chases material and knows which crew is where. Email [email protected] for anything you would rather put in writing, including fabrication drawings, insurance documents and privacy or data requests.
Someone answers during normal business hours, Monday to Friday, Central Time. Outside those hours, calls and emails are picked up the next working day. We do not publish an answer-within-X promise, because during a hail week it would be a lie. What we will say: a data request sent to that email is answered within 14 days, and enquiries are kept for 18 months.
The support chat at the bottom right of this page goes to the same office. It keeps your conversation in your own browser so you can come back to it. If nobody is at a keyboard, leave your number in it and the office will call.

No charge, no obligation
Measured roof inspection and a written estimate
Somebody gets on the roof, photographs what is wrong, and writes the price line by line. You keep the report whether or not you hire us.
An estimate is not a binding quote. Price and scope are fixed by a signed contract, and any change is written and priced before the work happens.
