Holds Water for Two Days After Rain
That is the case silicone was made for, once drains are cleared.

Silicone Coating That Holds Up Where Water Sits After Rain
As a Hastings silicone roof coating contractor, we spray silicone over primed metal and flat roof sections where ponding water would break down other coatings.
- Made for low spots
- Wet film checked each pass
- Recoats stay silicone

Is Silicone Roof Coating Right for Your Hastings Roof?
Hastings silicone roof coating fits some roofs far better than others. Four common cases and where each one starts.
If Your Roof
Mixes a Flat Addition With Sloped Steel
The flat part takes silicone and the sloped panels can take acrylic.
Start With
Split System
If Your Roof
Gets Walked Every Week for Unit Service
Heavy foot traffic tears silicone, so walkway pads go in with it.
Start With
Silicone Plus Walk Pads
If Your Roof
Already Has an Acrylic Coating
Silicone can go over acrylic with primer, but never the reverse later.

Roof Conditions
Silicone Roof Coating for Hastings Ponding Problems
These are the roof conditions that steer an owner toward silicone, and what has to happen to each before spraying.
Ponding
Birdbaths in the Field
Shallow water rings stay behind after a storm on low-slope panels and flat sections. Silicone tolerates that water, but we still clear drains and scuppers so the ponds shrink.
Drains
Clogged Drains and Scuppers
Leaves and grit block the outlets, which turns a short pond into a long one. Outlets are cleaned and their flashing is sealed before any coating.
Old Coating
Chalky Old Coating
An earlier acrylic or aluminum coating turns powdery. Washing and a bleed-blocking or bonding primer give silicone a surface it can grip.
Seams
Open Seams on Flat Sections
Seams on flat additions split as the deck moves. Reinforcing fabric in a base coat bridges them before the full silicone coat.
Curbs
Cracked Flashing at Units
Rooftop unit curbs and pipe boots leak where flashing has cracked. Each one is cleaned, primed, and wrapped with fabric and silicone.
Hail
Hail Dents and Bruises
Hail leaves dents and torn spots in old coatings. Damaged areas are cut back to firm material and patched so the new film is even.
Commercial Roof Coating Options for Hastings
Silicone is one of four systems we apply. This table compares them on the three things that most often decide a flat or low-slope roof.
| System | Ponding Water | Foot Traffic | Later Recoat |
|---|---|---|---|
| Silicone | Holds up under standing water | Needs walkway pads | Silicone only |
| Acrylic | Softens where water sits | Moderate | Acrylic or silicone |
| Urethane | Fair with a top coat | Handles heavy traffic | Matching system |
| Spray foam | Can be shaped to drain | Fair with granules | Original top coat type |
Benefits
Benefits of Coating Your Roof
Silicone earns its place on roofs that stay wet. Here is what it changes on those sections.
Stands Up to Ponds
Silicone stays intact under water that sits for days, where water-based coatings would soften and wash thin.
Steady in the Sun
Ultraviolet light breaks down many coatings, but silicone resists it, so it keeps its film on exposed flat roofs through hot Nebraska summers.
Fewer Coats
Low-slope roofs often take silicone in one or two passes over primer, which shortens the time crews spend on the roof.
Renewed by Recoating
A cleaned silicone surface takes a fresh silicone coat, so the system can be renewed instead of replaced.
Standing Water Still There Two Days Later?
Take a photo of the pond and the nearest drain before it dries. That shows us whether outlets need work before a silicone coat goes on.
Process
Silicone Roof Coating Steps in Hastings
Silicone goes on in one pass more often than other coatings, so the prep before it carries most of the work.
- 01
Inspect Your Roof
Ponding areas are measured, drains are checked, and an adhesion test patch shows whether the old surface will hold silicone.
- 02
Clean the Surface
Washing removes dirt, chalk, and loose coating from the roof. Silicone sticks only to a clean, dry surface, so cleaning is never cut short.
- 03
Prime Where Needed
Bare steel, rust, and old coatings get the primer the silicone maker lists for that surface.
- 04
Reinforce Details
Seams, curbs, drains, and pipe boots get fabric set in silicone before the field coat.
- 05
Spray and Measure
The field coat goes on at the listed thickness. Wet film gauges confirm coverage, and thin spots are recoated.
Other Silicone Roof Coating Pairings in Hastings
Silicone often works beside another system on the same building. These are the pairings we set up most.
Commercial Metal Roof Coating
Steel roofs with exposed screws get fastener and lap work first, and silicone can then cover the low sections of that steel.
Hastings Commercial Metal Roof Coating
Spray Foam Roofing
Foam can be built thicker at low spots to push water toward drains, and silicone is a common top coat over it.
Hastings Spray Foam Roofing
Shingle Roof Coating
Mansards and sloped shingle sections on the same building can be coated while the flat roof gets silicone.
Hastings Shingle Roof CoatingFAQ
Hastings Silicone Roof Coating FAQ
Answers about silicone on Hastings commercial roofs.
How much does silicone roof coating cost on a Hastings commercial building?
It falls within our coating planning range of about $2.50 to $4.00 per square foot. Silicone costs more per gallon but often needs fewer coats on low-slope roofs. Prep, primer, seam work, film thickness, roof size, and access move a project within that range.
How many coats of silicone roof coating does a Hastings metal roof need?
One or two coats over primer and reinforced seams covers many metal roofs here. The count follows the film thickness the maker specifies, and a pail covers its labeled area only at that thickness. Wet film readings during spraying confirm each coat.
Can silicone roof coating go over an old acrylic coating in Hastings?
Usually, with the right primer. The old acrylic is washed, loose areas are scraped, and an adhesion test patch is run first. If the test holds, silicone goes over it. The reverse fails later on, because acrylic will not bond to silicone.
How long does silicone roof coating last on a Hastings metal roof?
Thickness matters most. Coating makers rate silicone by dry film thickness, so a heavier build carries a longer rating. Ponding, hail, foot traffic, and dirt all wear it down, and a cleaned surface can take a new silicone coat to extend the system.
Silicone vs acrylic roof coating: which suits a Hastings commercial metal roof?
Low spots that hold water point to silicone, and good slope with quick drainage points to acrylic. Silicone resists ponding and sun but gathers dirt and turns slick when wet. Acrylic recoats easily and stays cleaner, though standing water breaks it down.
What are the downsides of silicone roof coating for Hastings buildings?
Dirt pickup, slick footing, and a one-way recoat path. Only silicone bonds well to silicone, so later recoats stay silicone. Wet silicone is slippery for service techs, and heavy traffic can tear it, which is why walkway pads go in on busy roofs.
