Simsbury Commercial Roofing Contractor
Adding Insulation at Reroof Without Overloading the Structure
As a Simsbury commercial roofing contractor, we reroof commercial buildings and add insulation, handling the state's structural snow-load question before anything is ordered.
Simsbury Commercial Roofing and Added Insulation
Simsbury commercial roofing jobs often add insulation, and in Connecticut that can raise a structural question that has to be answered first.
Connecticut's amendment to the existing building code, section 304.1.1, calls for roof members that carry snow to meet current design loads when a reroofing permit adds insulation R-value. Simsbury's ground snow load in the state code is 35 psf.
Exceptions cover buildings designed under the 1978 or later state codes and buildings an engineer confirms can carry the load.
- Building age and design code checked first
- Engineer review arranged when the exception needs it
- Insulation thickness set before ordering
Commercial Roofing Problems on Older Simsbury Buildings
Older buildings in town tend to show these six conditions at reroof time.
Thin Original Insulation
Older roofs carry an inch or two of insulation, so heat escapes and melts snow from below, feeding ice at the edges.
Two Roofs Already in Place
A second roof laid over the first adds weight and rules out another recover, so tear-off comes first.
Drift Weight at Walls
Snow piles against parapets and taller walls, adding load right where older framing has the least to spare.
Low Spots Over Long Spans
Long joists deflect over time, and the low spots between supports hold water after rain and melt.
Short Wall Flashing
Adding insulation raises the roof surface, which leaves old wall flashing too short to reach above it.
Curbs Too Low After the Upgrade
Thicker insulation brings the membrane up the curb, so low curbs must be raised to keep flashing tall enough.
What Insulated Commercial Roofing Gives Simsbury Buildings
An insulation upgrade done with the structure in mind brings four gains.
More Insulation Over the Deck
A thicker layer under the new membrane keeps heat inside and cuts the melt that feeds ice at the eaves.
A Structure Cleared for Snow
The code question is answered before the order, so the upgrade does not leave the roof short on capacity.
Curbs and Walls Raised to Match
Curbs and wall flashing are brought up to the new roof height, keeping every top edge above the water line.
Old Layers Off the Building
Tear-off removes the weight of past roofs, freeing capacity for the new insulation.

The new, thicker insulation and cover board go down, curbs and walls are raised, and the membrane is installed and flashed.

We confirm the building's design code and, where the exception needs it, line up an engineer's review before the permit.

Simsbury Roofing Questions
What Simsbury owners ask before adding insulation at reroof.
Question about your own roof?
Call UsDoes adding insulation during a Simsbury reroof trigger a structural check?
It can. Section 304.1.1 of Connecticut's existing building code amendment calls for snow-carrying members to meet current loads when a reroof permit adds R-value. Buildings designed under 1978 or later codes, or confirmed by an engineer, are exceptions.
What adds to Simsbury commercial roofing cost with an insulation upgrade?
The insulation itself, raising curbs and wall flashing to the new height, tear-off of old layers, and any engineer's review the building needs. Core cuts show how much insulation is there now.
How do I know if our building was designed under the 1978 codes?
Building permits, drawings, or the town's records usually show the construction date and design. We help track that down before the permit.
Can we skip the insulation to avoid the check?
A reroof with no net increase in R-value is one of the exceptions, but the energy code and your heating bills both argue for adding it. We price both ways so you can compare.
Where can I find a commercial roofing contractor near Simsbury who handles the code side?
Ask whether the 304.1.1 question will be answered before the order. We sort it out as part of every Simsbury reroof with added insulation.
Does commercial roofing for Simsbury businesses use the same snow load as Hartford?
No. The state code lists 35 psf for Simsbury against 30 psf for Hartford, which matters for drifts and for any check on added weight.
Does thicker insulation change our drains?
It raises the roof surface, so drain bowls and scuppers are reset to the new level. Tapered insulation is cut to slope water toward them, which is a good moment to fix any ponding.
