Shingle Tabs
Tabs need to be flat and sealed to the course below. Lifted tabs are hand-sealed, and missing ones are replaced to match. Matching tabs keep the coated roof even in color.

As a Plainfield shingle roof coating contractor, we coat asphalt shingle roofs on commercial buildings and churches while the shingles still lie flat and the deck is firm.
Plainfield shingle roof coating works on a narrow set of roofs. These rows show where it fits.
| What You See On The Roof | Coat The Shingles | Repair, Then Coat | Reshingle |
|---|---|---|---|
| Flat shingles losing granules | Usually Fits | Sometimes | Rarely |
| A few missing tabs, rest sealed down | Sometimes | Usually Fits | Rarely |
| Curling or cupped shingles | Rarely | Rarely | Usually Fits |
| Soft spots in the deck | Rarely | Sometimes | Usually Fits |
| Worn flashing at vents and valleys | Sometimes | Usually Fits | Rarely |
Half dots mean the shingles can take coating once tabs, boots, and flashing are repaired; curled shingles call for a new roof.
Shingle coating depends on five details, checked one at a time before anything is sprayed.
Tabs need to be flat and sealed to the course below. Lifted tabs are hand-sealed, and missing ones are replaced to match. Matching tabs keep the coated roof even in color.
Pipe boots crack and vent flashing loosens with age. These are replaced or resealed before coating so the film is not bridging a gap. New boots last far longer than caulk over old ones.
Valleys carry the most water and wear the fastest. Worn valley shingles or metal are repaired, then reinforced with fabric. Valleys get the heaviest coat on the roof.
Water running off a coated roof needs a clean edge into the gutter. Loose drip edge is refastened and gutters cleared. Clear gutters keep coated edges from staying wet.
Trapped moisture under a coating causes trouble. We check the ventilation and look for damp decking from inside where we can. Poor ventilation is fixed before any coating goes on.
Many properties with shingle roofs also have steel or flat sections nearby.
Steel shops or warehouses on the same lot.
Flat entry canopies that hold water.
Sloped steel additions that drain.
Low sections that need insulation.
Our coating made for asphalt shingles.
Coating aging shingles postpones a tear-off and keeps the building in use during the work, including Sunday services and weekday office hours.
| Factor | Coating The Roof | Tearing Off And Replacing |
|---|---|---|
| Shingles | Stay in place, sealed and coated. | Torn off and hauled to a landfill. |
| Price Range | About $2.50 to $4.00 per square foot. | About $5 to $8 per square foot. |
| Granule Loss | Coating locks loose granules down. | New shingles with full granules. |
| Inside During Work | Services and offices keep running. | Deck exposed during the swap. |
| Color | Matched to the building. | Chosen from the shingle maker's line. |
| Ventilation | Checked before coating starts. | Updated with the new roof. |
Granule loss is often the first sign a shingle roof is aging. Call us and we will check whether it can still be coated.
Shingle coating has a narrow window, so the walk decides whether we go ahead at all.

We check that shingles lie flat, test adhesion on a small area, and look for soft decking. If the roof needs reshingling, we say so on the spot.
Cracked boots, loose vent flashing, and missing tabs are fixed first, so the coating covers a closed roof.
A low-pressure wash removes dirt and moss without stripping granules. The roof dries fully before coating.
A coating made for asphalt shingles goes on in even passes, with extra care at valleys, steeples, and edges.
Together we walk the coated roof, check valleys and flashing again, and confirm gutters and downspouts flow freely before the crew leaves.
Shingled offices and churches often sit next to steel or flat sections.

A metal maintenance building or garage behind the main building gets the full steel coating system. Both systems go in one written scope with their own line items.

Sloped steel additions that shed rain quickly take acrylic coats in a matching color.

A flat section between shingled roofs can be foamed and coated to drain toward the gutters.
Answers about coating asphalt shingles on commercial buildings and churches.

Question about your own roof?
Call UsCoat when shingles still lie flat, stay attached, and are only losing granules and drying out. Reshingle when they curl, go missing, or the deck feels soft. Coating skips the tear-off and disposal, and our published range runs about $2.50 to $4.00 per square foot for coating against about $5 to $8 for replacement.
Use a coating made for asphalt shingles, usually a breathable acrylic or silicone that bonds to granules without trapping moisture. Metal roof coatings are not swapped in. We test adhesion on a small patch first and confirm attic or plenum ventilation, since moisture trapped under a coating causes problems.
On aging but intact shingle roofs it does: shingles flat, sealed down, and the deck solid. The coating seals the surface, holds loose granules, and reflects sunlight. Over curled or lifted shingles or a wet deck it fails, so we walk the roof first and tell you plainly if it is a poor candidate.
Church roofs can be coated when the shingles are flat and well attached. Steep sections need planned access and anchor points before work starts. Coating around steeples, valleys, and flashing gets extra care, colors are matched to the building, and damaged shingles and flashing are repaired first.
Most of the time goes into the walk, repairs, and washing, with the coating itself taking a few dry days. Steep church roofs take longer because of access. We schedule around services and office hours and give you the plan before work starts.
Coating gives the roof one even color and covers stains and patchy granule loss. We match the color to the building, and church roofs often keep a traditional dark tone.
