Commercial Roof Replacement in Fort Collins

Tear-Off and Full Replacement for Roofs That Can't Be Saved

The replacement plan explains tear-off or recover assumptions, insulation and drainage needs, occupied-building phasing, system options, and closeout requirements. Some roofs get one more recover cycle. Others need everything stripped to the deck. We make that call based on what a core cut and a walk of the roof actually show us, and when full tear-off is the honest answer, here's how we run that job around Fort Collins buildings near Colorado State University, the Poudre River corridor, and Old Town's older commercial stock.

Why Some Roofs Don't Qualify for a Recover

A recover only works over a dry, single-layer, structurally sound roof. Multiple layers already stacked from past recovers, saturated insulation, or a deck that's soft in more than a spot or two all disqualify a roof from getting another layer on top. Buildings near CSU's main campus and the older commercial blocks close to it often have two prior roof systems already layered, which pushes them straight to tear-off by code.

Weight matters here too. Every layer of old roofing left in place adds dead load to the structure. On older buildings we've measured, stacking a third system on top of two existing ones can push a roof assembly closer to its structural limit than most owners realize until an engineer flags it.

Deck Repair Once the Old Roofing Comes Off

Tear-off is when the deck finally shows itself. Wood decking on older buildings near the river corridor sometimes has moisture damage we couldn't see or core-sample accurately until the membrane and insulation were stripped away. Steel deck buildings show different problems, usually rust at fastener penetrations or at low points where ponding sat for years.

We price deck repair as an allowance built into the bid rather than a surprise change order, because on a tear-off there's almost always some amount of deck work once we see what's underneath. Owners planning a tear-off should expect that conversation, not be blindsided by it.

Disposal and Site Logistics on Tight Urban Lots

Old Town buildings and properties close to campus often sit on small lots with limited staging space and street parking that can't be blocked for long. We plan dumpster placement, crane or conveyor staging, and material delivery timing around those constraints before the job starts, not on the first morning of demo.

Torn-off membrane, insulation, and old flashing all get hauled and disposed of according to local requirements. On buildings with older modified bitumen or built-up roofing, we handle that disposal the same way regardless of age, since guessing at material composition on a tear-off isn't something we do.

• Core cuts confirming layer count and deck condition before bidding
• Structural dead-load check on multi-layer roofs
• Deck repair allowance built into the tear-off price
• Staging and disposal plan for tight urban lots
• Dry-in sequencing to limit open-roof exposure overnight
• New assembly matched to current code and building use

Sequencing Tear-Off Around Weather

We never open more roof than we can dry-in the same day during hail season. That means a full building tear-off gets broken into sections rather than stripped all at once, even though that adds a little time to the schedule. A roof deck exposed to an afternoon hailstorm with no membrane on it is a much bigger loss than a few extra days of labor.

Cold-weather tear-offs run into a different constraint: adhesives and self-adhered membranes need minimum temperatures to bond properly. We schedule winter tear-off work around forecast highs rather than a fixed date, and we'll say so plainly during the bid instead of promising a hard finish date we can't control.

New Assembly Choices After Tear-Off

Once the deck is bare, we're not locked into matching the old system. A building that had built-up roofing for thirty years can move to TPO or a mechanically attached EPDM system if that's the better fit for the current use and rooftop equipment load. We walk owners through those options rather than defaulting to whatever was there before.

Tapered insulation gets added at this stage more often than not, since a full tear-off is the cheapest point in a roof's life to correct drainage problems that have been a nuisance for years.

Tear-Off Questions From Building Owners

How do you know if my roof needs tear-off instead of a recover?

We core cut in several spots to count existing layers and check insulation moisture. Two or more layers already in place, or any wet insulation, generally rules out a recover.

Will you find problems once the old roof is off that weren't in the original bid?

Some deck repair is close to certain on any tear-off, which is why we build an allowance into the price up front rather than treat it as a surprise.

How long does the roof stay open during tear-off?

We section the work so no more area is exposed than we can dry-in before end of day, especially during hail season. A full building can still take two to four weeks depending on size and deck repair needs.

Can you work around a tight downtown lot with no staging space?

Yes. We plan dumpster and material staging around what a lot allows before work starts rather than improvising it on day one, which matters most on Old Town blocks with street parking constraints.

Does a full tear-off let us switch to a different roof system?

Yes. Once the deck is exposed we're not tied to the prior system and can spec whatever assembly fits the building's current use and rooftop equipment.
