Stains In The Main Office
A ceiling stain spreads near an exterior wall in the office or store.
A membrane seam or the wall flashing at the base of the parapet has opened.

As a Granby commercial roofing contractor, we install, replace, and repair TPO, EPDM, and metal roofs on properties with offices, shops, and storage buildings on one lot.
Granby commercial roofing jobs often cover more than one building: an office or store with a flat membrane roof, plus a shop, garage, or storage building with metal panels out back. Each roof ages at its own pace.
We walk every roof on the property in one visit and write one plan that lists what each needs now and what can wait. That lets owners budget roof work across buildings instead of reacting to leaks.

Mixed properties leak in different ways on each building. These pairs show the usual causes.

A membrane seam or the wall flashing at the base of the parapet has opened.
Water drips onto benches or equipment in the shop during rain.
Metal panel fasteners have backed out and their washers have cracked.
Stains show at the wall where an addition joins the original building.
The flashing where the lower roof meets the taller wall has split or was never tied in.
Leaks show in winter where a low roof sits below a taller one.
Snow sliding off the upper roof piles up on the lower one and melts against the wall flashing.
One plan for every roof on the property makes the work easier to schedule and pay for.
A single visit covers the main building, shops, and storage, so nothing is missed between buildings.
The plan ranks each roof by need, so the most urgent work is done first and the rest is budgeted.
Where an addition meets an older wall, new flashing ties the two roofs together.
Each roof gets the system and details that fit it, from welded TPO seams to new panel fasteners.
One property here can use more than one of these systems.

Welded white membrane suits flat office and store roofs and holds tight around rooftop units.

We walk every roof on the lot, take core cuts on the membrane roofs, and check fasteners, laps, and trim on the metal ones.
The written plan lists each roof, what it needs, and the order to do it in, so you can budget across the property.
The roof with the worst problems goes first, sections closed each night, with access kept clear for the other buildings.
Other roofs follow on the schedule you choose, and the record for each building is kept for future repairs.
After the first building is done, we set a check date for the remaining roofs so the plan stays on track.

What Granby owners ask about roofing a property with several buildings.
Yes. We install, replace, and repair TPO and EPDM roofs on commercial buildings in Granby, and metal roofs on shops and storage buildings. Each job starts with a roof walk and core cuts where needed, and permits go through Granby's own building department.
More roofing questionsYes. We walk every roof on the property, rank them by need, and schedule the work so the most urgent roofs go first and the rest fit your budget.
The flashing where the lower roof meets the taller wall often splits or was never tied in. We strip it back and flash the new roof up the wall.
Yes. One scope can cover a membrane roof on the main building and metal panels on shops, with each roof described separately.
Yes. Snow guards on the metal roof hold snow in place so it melts slowly instead of dropping onto the lower roof and piling against the wall.
Yes. The plan lists every roof on the property, and buildings can be moved up or back as budgets and needs change.
Every roof on the lot: membrane roofs get core cuts where needed, metal roofs get fastener and trim checks, and the joints between buildings get a close look. You get one written plan for all of it.
