Brittle Daylight Panels
- You See
- Panels gone yellow or chalky that crack when pressed near the screws.
- What It Means
- Sunlight has broken down the plastic. Brittle panels get replaced, since coating over them leaves a weak spot that splits again.
Redding, CT Skylight And Panel Roofs
As a Redding metal roof coating contractor, we reseal or replace aging skylights and daylight panels, reflash their curbs, and coat the commercial metal roof around them.


Daylight Panels
On a Redding metal roof coating job, the skylights get our attention before the steel does. Translucent panels yellow and turn brittle with sun, and their fasteners crack the plastic as it ages.
We decide panel by panel whether to seal, cover, or replace, then reflash every curb. Only after the daylight openings are watertight does the coating go on the surrounding steel.
Skylights and translucent panels fail in their own ways. These are the conditions that set our repair list on roofs with daylight openings.
Fixing the skylights first and then coating the field gives a Redding metal building a roof that sheds water at its weakest openings.
New or resealed panels keep natural light coming into the work area.
Coating laps up onto reflashed curbs for a continuous edge.
Seams between clear and steel panels are taped and coated.
All steel fasteners across the field sit under the cured coat.
Reflective finishes reduce heat build-up on panels around the skylights.
Marked and guarded skylights lower the risk for anyone servicing the roof.
Existing metal panels remain on the building, so only failed skylights come out.
Closing curb and lap leaks ends the puddles under skylights.
Five systems cover the metal buildings we coat in Redding. Slope, skylight layout, and insulation needs decide which one we recommend.

Elastomeric coating over the steel field after skylights are replaced or sealed and curbs are reflashed. We keep coating off the clear panels so they still pass light.
Commercial metal roof coatingHandles water that collects on the upslope side of curbs on low-slope roofs. Silicone sticks well around flashing, and any recoat later has to be silicone as well.
Silicone roof coating
Bright, water-based, and fast to clean up, for pitched metal roofs with skylights spaced along the slope. Application waits for warm, dry stretches with mild nights.
Acrylic roof coating
Insulates the field and builds up neatly to skylight curbs on low-slope buildings. Clear panels are masked, and curbs get raised if foam would sit too close to their tops.
Spray foam roofing
Covers shingled office sections or entry roofs attached to a skylit metal building. Shingles have to be flat and hold their granules, and any loose ones are fixed first.

Skylights get fixed first, then the field. These five steps keep that order.
We check each skylight and daylight panel for cracks and brittleness, test curb flashing, look at laps between clear and steel panels, and walk the field for loose screws and rust.
Brittle or cracked panels come out and new ones go in with gasketed fasteners. Panels still flexible and clear get their laps retaped and their screws resealed.
Curb flashing is reset or replaced and sealed to the steel. Where debris builds up above a curb, a diverter goes in so water runs around it.
With clear panels masked, the steel is washed, rust is primed, and base and finish coats go on, built thicker at curbs and the laps beside skylights.
Thickness readings are taken across the field and at each curb. Masking comes off the daylight panels, and any coating overspray on them is cleaned away.
We also coat commercial metal roofs with and without skylights in these towns near Redding.
What owners of skylit commercial metal buildings in Redding ask us most.

Most Asked
We keep coating off clear panels so they still let light through. Brittle or cracked panels get replaced, and flexible ones get resealed at their laps and screws. Owners who no longer want a skylight can have it swapped for a steel panel, which is then coated with the rest of the field.
Coating runs about $2.50 to $4.00 per square foot of roof area as a ballpark, and full replacement about $5 to $8 per square foot. Skylight work adds to the coating figure based on how many panels need replacing and how many curbs need new flashing. The final price follows a site visit.
Yes. Shops and warehouses that use skylights for daylight keep that light, since we mask the clear panels during coating and replace any that have yellowed or cracked. Work runs in sections so the space below stays in use while we coat around the openings.
Ask how the skylights are handled before the coating is priced. Our estimate lists each daylight panel as replace, reseal, or leave, plus every curb that needs new flashing. That list comes first, and the coating price is built on top of it.
Plastic panels expand and shrink more than steel, and a screw driven tight leaves no room for that movement. Sunlight also makes the plastic brittle over time. Replacement panels go in with oversized holes and gasketed fasteners so they can move without splitting.
Yes. Translucent panels blend into the roof and break underfoot, so we mark every one and keep foot traffic off them throughout the job. Owners can add screens or guard rails over skylights near units and ladders so service techs stay protected after we leave.
Before. Replacing a skylight after coating means cutting into finished work and patching it. We swap or reseal daylight panels and reflash the curbs first, then coat the steel field so the coating laps cleanly onto the new curb flashing and the fresh panel seams.
