What a roof condition score tells you, and what it doesn't

If you manage 50 roofs, you can't hold 50 inspection reports in your head. You need a way to sort them. That is what a Roof Condition Index (RCI) score is for.

TEMA grades every roof on a 1 to 5 scale. The score gets you to the right conversation fast. It doesn't finish the conversation.

What the 1 to 5 scale means in practice

Each score pairs a risk level with an estimated remaining life and a typical response:

• 5, Excellent. Very low risk. Estimated life of 15+ years. Routine preventive maintenance (PM) only.
• 4, Good. Low risk. Roughly 8 to 15 years. Targeted repairs plus structured PM.
• 3, Fair. Moderate risk. Roughly 3 to 8 years. Immediate repairs, PM, and 3 to 5 year capital planning.
• 2, Poor. Elevated risk. Roughly 1 to 3 years. A major repair campaign plus replacement planning.
• 1, Very Poor. High risk. Under 1 year. Immediate replacement.

Read the table as a decision guide, not a forecast. A 2 doesn't mean the roof fails in 18 months. It means you should be planning the replacement now instead of discovering the need during a leak call.

The middle of the scale is where most of the budget conversations happen. A 3 is the hardest score to manage because nothing is on fire, but the clock is running. That is where a 3 to 5 year capital plan earns its keep.

Why the worst section matters

Most commercial buildings don't have one roof. They have several sections, often installed in different years, with different membranes and different exposure. A building can have a 4 over the main block and a 2 over the addition.

If you average those, you get a 3 and a number that describes no actual roof. The section in worst shape is the one that leaks, drives the work orders, and eventually forces the project.

That's why a TEMA assessment scores every roof section on its own. You see the 4 and the 2 side by side, not one blended number that hides the problem.

When you review a score, ask whether it is a building number or a section number. A building scored 4 with one section at 2 needs a different budget line than a building that is a clean 4 throughout.

How RCI connects to your budget horizon

The estimated remaining life is what turns a score into a capital plan. A building at 2 belongs in your next one to three years. A building at 3 belongs in a 3 to 5 year window. A building at 4 or 5 is mostly an operating expense, handled through PM.

This is the practical value of the scale. It lets you sort the portfolio by when the money is likely needed, not by building age or by whichever property called last. You can see which replacements are coming and spread them out instead of absorbing three in one budget year.

The goal isn't a perfect forecast. It's an order of operations you can defend.

What an RCI score can't tell you on its own

A condition score is a starting point. A few things sit outside it, and each can change the decision.

Moisture under the membrane. A roof can look serviceable on the surface and hold wet insulation underneath. Finding that takes a different method, such as infrared scanning or core sampling. A good score doesn't rule it out.

Warranty status. The score says nothing about whether a warranty is still in force, what it covers, or whether past repairs or missing maintenance have put it at risk. That matters when you're deciding between repair and replacement. It needs its own record.

Deck condition. The structure beneath the roof system is often hidden until work starts. A replacement scoped as a re-cover can change when the deck turns out to be a problem. That is an engineering question, and it belongs with a qualified professional.

Why a roof got its score. Two roofs can both be a 3 for very different reasons. One is aging evenly. The other has a drainage problem that will keep damaging whatever you put on it. The same number can call for different actions.

How scores roll up into a portfolio view

This is where the scale pays off. Once every roof has a score, an estimated life, and a recommended response, you can answer questions that used to take a month of calls.

How many buildings sit at 1 or 2? How many are at 3 and heading toward replacement? What does the next three years look like if you do nothing, and what does it look like if you start now?

That view also gives you something to bring to finance. A ranked list with reasoning is easier to defend than a request for money because "the roofs are old." It shows which buildings come first and why, and it lets you set an order before the leaks set it for you.

One caution. A portfolio rollup is only as good as the detail underneath it. If the scores are old, or built from photos instead of a documented walk of each section, the totals will look tidy and mislead you.

Use the score to sort. Then go one level deeper on the buildings that matter most.
