Drips at the panel overlaps
Likely Cause
Ice in the side laps pushed the panels apart and the old sealant no longer touches both sides.
What We Do
Open the lap, lay new butyl tape, and stitch it closed with fresh screws.

Laps and Ridge Caps Resealed Before Another Winter Opens Them
As a St. John commercial roof repair contractor, we reseal laps, ridge caps, skylights, and wall flashing on metal shops, offices, and storage buildings.
St. John Commercial Roof Repair After Freeze and Thaw
St. John commercial roof repair on metal buildings runs on the calendar. Winter freeze and thaw pries laps and ridge caps open, and spring is the window to close them.
Water that sneaks into a lap freezes and wedges it a little wider every cold night, so small gaps in March become drips by April.
A spring visit reseals laps, refastens trim, and replaces loose screws before summer heat and fall rain test them again.
- Spring reseal visits
- Side and end laps reopened and sealed
- Skylight panels checked and swapped
- Loose screws replaced
Commercial Roof Repair Signs on St. John Metal Buildings
Metal roofs tell you where they leak. These signs show up most after a hard winter.
Water along the ridge in spring
Likely Cause
Ridge cap closures and fasteners loosened as panels moved through cold nights and warm days.
What We Do
Reset the closures, reseal under the cap, and refasten it along both sides.
Light and water through a skylight
Likely Cause
Old fiberglass skylight panels turn brittle and crack under snow load or hail.
What We Do
Replace the skylight panel and seal its laps to the metal around it.
Stains where the roof meets a wall
Likely Cause
Wall flashing pulled away as the building moved, opening a gap along the top edge.
What We Do
Refasten the trim, seal the top edge, and close the gap behind it.

St. John Commercial Roof Repair Questions
Common questions from St. John shop and office owners.
Is Metal Roof Repair in St. John Part of Your Work?
Yes. Shops, offices, and storage buildings with metal roofs in St. John get worn screws replaced, laps and ridge caps resealed, rusted panels swapped, and wall and skylight flashing fixed. The whole fastener pattern near each leak gets checked, since neighboring screws age together.
What Does Ridge Cap Repair Involve?
The cap gets lifted where needed, the foam or metal closures underneath are reset or replaced, new sealant goes under the cap, and the cap is refastened along both sides. That stops wind from lifting it and rain from running along the ridge.
How Is a Skylight Leak Repair Done on a Metal Roof?
Brittle or cracked fiberglass panels come out and new panels of the same profile go in. Their laps get butyl tape and new fasteners like the steel around them, so the skylight seals to the roof on all sides.
Why Spring for Metal Roof Resealing?
Winter does the damage, and spring shows it. Resealing after the last hard freeze closes gaps before summer rain and heat test them, and sealant cures better once nights stay above freezing.
Do Small Shop Buildings Need a Permit for Repairs?
Whether a permit applies depends on the scope of the work and the town. Ask the local building office before larger panel replacements, since that office decides what counts as maintenance.
