FAQ
Most of the roofing questions we field from owners and asset managers are not technical, they are decisions about money and risk dressed up in technical language. Below are the questions we hear most often, answered the way we answer them for clients: directly, without a sales angle, and with an eye on your reserves and your liability. We advise on the owner's side of the table, so none of these answers are pointing you toward a roof we want to sell you.
How do I know whether to repair or replace my roof?
The deciding factor is rarely the leak in front of you. It is the percentage of the assembly that is wet and the amount of service life remaining. A roof with isolated, repairable damage over dry insulation is usually worth repairing for years. A roof with widespread saturation, failing seams across the field, and shrinking membrane is throwing good money after bad with each patch.
We use a moisture survey and a remaining-service-life estimate to make this call objectively. As a rule of thumb, once roughly a quarter of the insulation is wet, repairs stop being economical and replacement planning should begin.
What does my roof warranty actually cover?
Far less than most owners assume. A manufacturer warranty typically covers defects in the membrane material, and sometimes installation, but it almost always excludes damage from foot traffic, equipment work, storms, ponding, and lack of maintenance. A material-only warranty pays for the product but not the labor to install it, which is the larger cost.
The strongest form is an NDL (no dollar limit) warranty, which caps nothing for covered defects. Whatever you hold, read the maintenance requirements closely, because failing to document inspections is the most common reason valid claims get denied.
How often should a commercial roof be inspected?
We recommend a documented professional inspection twice a year, in spring and fall, plus an additional inspection after any major storm or after any trade works on the roof. Twice-yearly is also the cadence most warranties quietly require to stay valid.
Between professional visits, a quick walk after heavy weather to check drains and obvious debris costs nothing and catches problems early.
Are roof coatings a real solution or a band-aid?
Coatings are a legitimate tool when applied to a roof that is structurally sound and dry. On the right candidate, a fluid-applied restoration can add years of service life, improve reflectivity, and renew certain warranties at a fraction of replacement cost.
They are not a fix for a failing roof. Coating over wet insulation or open seams seals the problem in and wastes the spend. The honest test is whether the assembly underneath is sound, which a moisture survey answers before you commit.
How long should a commercial roof last?
Service life depends on the system, the install quality, and the maintenance it receives. As typical ranges, single-ply membranes such as TPO and PVC commonly run 20 to 30 years, EPDM 20 to 30 years, modified bitumen 20 years or more, built-up roofing 20 to 30 years, and metal systems often 40 years or longer.
The number that matters is not the published lifespan but the remaining service life of your specific roof, which only inspection can establish.
How much should I budget in reserves for the roof?
Reserve planning starts with a remaining-service-life estimate and a current replacement cost, then spreads that cost across the years until replacement is due. A roof with eight years left and a known replacement number gives you a clear annual set-aside.
We encourage owners to fund a reserve rather than treat replacement as a surprise capital event, and to revisit the figure each year as the roof ages and pricing moves.
What should I do the moment I find a leak?
Protect the interior first by moving inventory and equipment and containing water, then document everything with photos and dates. Do not let an unvetted contractor open up the roof before the cause is understood, because a leak that shows up in one spot often originates somewhere else entirely.
Water travels along the deck and through the insulation before it appears below, so leak triage is about tracing the path, not patching the stain.
What is the difference between a roofing contractor and a roofing advisor?
A contractor sells and installs roofs, and their recommendation is shaped by what they install. An advisor works for the owner, specifies what the building actually needs, writes the bid documents, manages the competitive process, and inspects the finished work without a financial stake in the installation.
The two roles are not in conflict, but they are not the same. We sit on your side so that the contractor's work is measured against an independent standard.
Why are roofing bids so hard to compare?
Because contractors bid to their own scopes. One bid may include tear-off, new cover board, and tapered insulation while another quotes a thin overlay, and the prices look comparable only because the scopes are hidden. The gap shows up as change orders later.
We level the field by writing a single detailed scope of work that every bidder prices, so you are comparing identical projects rather than marketing.
What happens to my roof after a major storm?
Storm damage is often invisible from the ground and even from a casual walk. Wind can loosen flashings and seams, hail can bruise a membrane without puncturing it, and the failure surfaces months later. Document the storm date, get a professional inspection promptly, and preserve evidence before any repairs.
Insurance and warranty claims both hinge on timely documentation, so the inspection after a storm is as much about the paper trail as the repair.
Should I get my roof inspected before buying a building?
Always. The roof is one of the largest deferred liabilities in commercial real estate, and a standard property condition assessment often gives it only a cursory look. An independent roof assessment during due diligence tells you the remaining service life, the moisture condition, and whether the warranty is transferable.
That information either protects your offer or becomes a negotiating lever worth far more than the cost of the survey.
Can I transfer the roof warranty when I sell the building?
Sometimes, and the details matter. Many manufacturer warranties allow a one-time transfer to a new owner, usually within a set window after closing and often for a fee, contingent on an inspection that confirms the roof is in good standing.
Missing the window or skipping the inspection can forfeit years of coverage, so warranty transfer belongs on the closing checklist, not an afterthought.
Is ponding water a serious problem?
Water that remains more than 48 hours after rain is a problem worth addressing. Ponding accelerates membrane aging, can void warranty coverage, adds structural load, and signals either inadequate slope or blocked drains.
The fix ranges from clearing drains to adding tapered insulation or crickets, but ponding should never be dismissed as cosmetic.
What maintenance keeps a roof from failing early?
Most premature roof failures trace back to neglect rather than product defect. A basic program prevents the majority of avoidable damage:
- Keep drains, scuppers, and gutters clear so water leaves the roof.
- Inspect and reseal flashings, pitch pockets, and penetrations on a schedule.
- Install walkway pads on service routes to protect the membrane from traffic.
- Coordinate with HVAC and other trades so equipment work does not damage the roof.
- Keep dated photo records of every inspection and repair for warranty purposes.
When does it make sense to bring in an owner-side advisor?
The highest-value moments are before a replacement, during an acquisition, and whenever you hold a portfolio large enough that roofs are a recurring line item rather than an occasional surprise. An advisor pays for itself by right-sizing the scope, leveling the bids, and catching defects before final payment releases your leverage.
If you are weighing a six-figure project on a single contractor's word, that is the moment an independent read is worth the most.
