What it does

Commercial roof coatings in Lewisville, TX buy years, not a new roof

Commercial roof coatings in Lewisville, TX are a life-extension for a roof that is fundamentally sound. A coating seals the surface, bridges small imperfections and reflects heat, and on the right roof it adds real years at a fraction of a replacement.

On the wrong roof it does harm. Coating over wet insulation seals the water underneath and takes away the evaporation path, so the assembly degrades faster with the coating than without it. Establishing which roof you have is the first step and it is not optional.

  • Right roof: membrane intact, insulation dry, seams and details sound
  • Wrong roof: wet insulation, failed seams, or an assembly at the end of its life
  • The test: a moisture scan, before anyone quotes a coating

Scope

Cleaning, seam reinforcement, primer and the coat itself

Most of the labor and most of the failures are in the preparation, so a bid that goes light on the first three steps is a bid worth questioning. A coating only suits a sound roof; where it is not, a recover or a full tear-off is the answer.

01Moisture survey
Infrared or capacitance scanning to find wet insulation. This decides whether the job proceeds at all.
02Cleaning
Power washing to remove dirt, chalk and biological growth. A coating over a dirty roof fails at the bond.
03Repairs and seam reinforcement
Open seams, splits and failed terminations repaired and reinforced with fabric before anything is coated.
04Primer
Where the substrate requires it. Some membranes need it and some do not, and the manufacturer specification decides.
05The coating
Applied at the specified thickness in one or two passes, which is what the warranty term depends on.
06Details
Curbs, drains, penetrations and parapets coated and reinforced individually.

Application and its workmanship warranty belong to the roofer; the coating warranty comes from the manufacturer.

How it runs

The roof gets tested for moisture before anything is coated

Sequence, with a genuine stop condition at step one.

Step one

Moisture scan and survey

Wet areas mapped. If there are many, a coating stops being the answer and the conversation turns to recover or tear-off.

Step two

Wash and dry

The roof is cleaned and left to dry completely. Coating over trapped moisture at the surface fails as surely as coating over wet insulation.

Step three

Repairs and reinforcement

Seams, splits and terminations addressed with fabric reinforcement where the specification calls for it.

Step four

Coat, at thickness, and inspect

Applied to the specified mil thickness and checked, because the warranty depends on the thickness achieved.

Good to know

Silicone against elastomeric, and when a coating is the wrong call

Including the answer to when you should be told no.

Silicone or elastomeric acrylic?
Silicone handles ponding water well and stays flexible, which suits roofs that hold water after rain. Acrylic elastomerics cost less and are easier to recoat, and they do not tolerate standing water as well. Ponding on your roof is usually what settles the choice.
When is a coating the wrong call?
When the insulation is wet, when seams have failed across the whole roof, or when the membrane is at the end of its life. In those cases a coating spends money to postpone a replacement by a short time and can make the eventual tear-off more expensive.
How long does a coating last?
Coating life depends on the system, the thickness applied and the roof underneath. Most systems are designed to be recoated at intervals. The manufacturer warranty term is the number to ask about, along with what it requires of you.
Will a coating stop an active leak?
Only if the leak is a surface issue that the coating and its reinforcement actually address. A leak coming through a failed termination or up from wet insulation will keep going, and coating over it hides the evidence without fixing the cause.
Does a coating count as a new roof for insurance?
Your carrier answers that one. Carriers treat coatings differently from replacements, so the carrier confirms the treatment before the work rather than after.

The next step

A moisture scan decides whether coating is even possible

The scan is the honest first step, and it is the one that can rule the whole service out. A roofer who scans first and then tells you a coating is the wrong answer has saved you the cost of finding out slowly.

A survey first means nothing to decide on the spot.

Coating inquiry

Address, roof age, and system, and a roofer books the scan.
