GranulesGranule Loss
Bald patches where granules have washed into the gutters expose the asphalt mat. Light loss can be coated; exposed mat needs repair first.

Henderson Shingle Roof Coating
We coat commercial asphalt shingle roofs in Henderson when the shingles are flat, firmly attached, and covered by a coating approved for shingles.
- Shingles Checked Row By Row
- Product Approved For Shingles
- Loose Tabs Fixed First
- Churches, Offices, Strip Centers
Can These Shingles Be Coated?
Shingle coating has a narrow gate. Roofs that land in the right column are usually better off with a re-roof.
Coatable Shingles
- Shingles lie flat and stay firmly attached
- Granule loss is light and the mat is covered
- Decking feels solid underfoot
- The coating maker approves its product over shingles
- The space under the deck shows no trapped moisture
Re-Roof Or Repair Instead
- Curling, cupped, or brittle shingles
- Missing tabs across large areas
- Exposed mat where granules are gone
- Soft decking or sagging between supports
- Shingle terms that coating would affect
Shingle Conditions We Check First
Four conditions decide most shingle coating calls. We look at each one before talking about products.
Granules
TabsCurled And Lifted Tabs
Tabs that curl at the corners or lift in wind break the flat surface a coating needs. Curling across a whole slope usually means a re-roof.
InsideStains Below The Deck
Water marks inside can point to failed flashing or a soft deck. We trace the source and check the decking before any coating plan.
JointsWhere Shingles Meet Metal
Churches and offices often join a shingle roof to a metal addition. That wall or valley joint is a common leak and gets fabric and coating.
Commercial Roof Coating Options for Henderson
A shingle building often has more than one roof type. This is how we handle each part of a typical commercial shingle property.
| Roof Area | First Check | Likely Path |
|---|---|---|
| Shingle main roof | Curling, granule loss, soft decking | Shingle coating or re-roof |
| Metal addition | Screws, end laps, rust | Metal roof coating |
| Joint between them | Flashing at the wall | Fabric and coating detail |
| Low-slope porch or canopy | Ponding and drains | Silicone if the deck is dry |
Benefits of Coating Your Roof
When the shingles pass inspection, a coating buys them more service. These are the gains owners weigh against a re-roof.
More Service From Intact Shingles
A coating approved for shingles seals the surface and holds loose granules in place on a roof that is still flat and attached. The building keeps its current roof instead of going through a tear-off now.
Less Tear-Off Waste
Old shingles stay on the deck, which keeps a full load of asphalt debris out of the dumpster and off the property.
Services Keep Running
Churches, offices, and stores stay open while crews work on the roof above, with entrances and parking planned around ladders and pails.
One Visit For Mixed Roofs
A shingle main roof and its metal addition can be coated in the same mobilization, which keeps the joint detail consistent.
Shingles Losing Granules Into The Gutters?
Granules in the gutters mean the shingles are wearing. Schedule an inspection to find out whether coating or a re-roof makes more sense.
Schedule Free InspectionHow We Coat A Commercial Shingle Roof
Shingle work starts with a strict inspection. The roof moves to the next stage only after it passes.
Step 1
Inspect Your Roof
We check shingle attachment, curling, granule loss, flashing, and the decking underfoot, then review the space under the deck for moisture and ventilation. A failed check ends in a re-roof recommendation instead of a coating plan.
Step 2
Confirm Product And Shingle Terms
The coating maker has to approve its product over asphalt shingles. We also review the shingle manufacturer’s terms with you, since a coating can affect them.
Step 3
Repair Tabs, Flashing, And Joints
Loose tabs get secured, failed flashing is redone, and joints where shingles meet metal or walls get fabric. Debris and loose granules are cleaned off before coating.
Step 4
Coat The Shingles And Metal Together
Approved coating goes on the shingles at the specified rate, and any metal addition is coated in the same visit. A final walk checks coverage at valleys, edges, and the joint.
Other Roofs On Shingle Properties
Shingle buildings in Henderson often carry metal or low-slope sections too.
Metal Roof Coating
Metal fellowship halls, shops, and additions beside a shingle roof take a metal coating over sealed screws and laps.
Commercial metal roof coating
Silicone Roof Coating
Flat porches and canopies that hold water get silicone, kept separate from the shingle coating.
Silicone for porches and canopies
Acrylic Roof Coating
Pitched metal additions that drain well can take a white acrylic that recoats easily.

Answers for owners of commercial shingle roofs deciding between a coating and a re-roof.
Eligibility
Can you coat an asphalt shingle roof on a commercial building?
Sometimes, when the shingles are intact and the coating maker approves its product over shingles. Curling, missing, or brittle shingles rule it out, exposed mat needs repair first, and shingle manufacturer terms can be affected. Many tired shingle roofs are better off re-roofed, while metal additions can still be coated.
How long does a shingle coating job take?
Inspection and repairs take most of the time, and the coating itself goes on quickly once tabs and flashing are fixed. Weather, roof size, and how much flashing needs redoing set the schedule, which we give you after the roof walk.
Before We Visit
What should a building owner have ready before a metal roof inspection?
Roof access details, leak history, and past repair records. Photos of ceiling stains, dates of hail or wind, and plans for new rooftop units or skylight panels help too, along with the building’s hours and loading dock schedule. On a shingle building, mention any re-roof bids already in hand.
Do coated shingles need different upkeep?
Upkeep means a yearly look at the valleys, flashing, and edges, plus clearing gutters so water leaves the roof. Loose tabs found later get secured and spot-coated. Any recoat uses a product the maker approves over its own earlier coat.
Churches And Offices
Can services or office hours continue while the shingles are coated?
Yes. Crews work outside on the roof, and the main disruptions are ladders at the walls and limited parking near the building. We set work hours around services, events, or office schedules and keep entrances clear during those times.
What if part of the building is metal?
Metal additions get a metal roof coating over tightened or replaced screws and sealed laps, often in the same visit as the shingle work. The joint between the two roofs gets fabric and coating so both sides meet without a gap at the wall.
