Is there such a thing as “Roof Reserves”?

This question came up in our recent Reserve Studies “under the hood” webinar (see, designed to provide a general introduction to what a Reserve Study is, and what useful and valuable information you’ll find in a Reserve Study.  Unfortunately, it was a specific question that was out of context of what I was addressing in the webinar. Even so, it was a good question, so I’ll answer it here.

The Straight Line (“Component”) method of funding Reserves is based on summing together individual pieces…  summing together the individual contributions required by each component. So the total Reserve contribution, and total Reserve Fund, can then be broken back down into those individual pieces (if one wishes). So one could identify “Roof Reserves” if the Reserve Study was prepared based on the Straight Line method.

On the other hand, in a “Cash Flow” (or “Pooled”) Reserve Funding methodology there is no such thing as contributions made towards an individual component. By extension, there is no such thing as a portion of the total Reserve Fund dedicated towards any particular component. This is because in such a methodology, total income to Reserves is balanced against annual total expenditures from Reserves without concern for if that annual expenditure was one or 50 projects. In such an analysis, Reserve cash flow is blind to individual projects. Unrestricting the cash in this manner is the most efficient use of Reserve Funds, allowing them to “flow” from one component to another as needed, which is one of the advantages of the Cash Flow method. The Cash Flow method is not inherently more or less risky than the Straight Line method. It is just different. Thus in a Reserve Study prepared by the Cash Flow method, there is no such thing as “Roof Reserves” or “Asphalt Reserves”, as the Reserve cash simply goes where it needs to go, it is not designated towards a specific project.

So an answer to the question depends on the methodology used in preparing the analysis. But let me suggest that the answer doesn’t matter. Even when using the straight line method, it is common that the Reserve Study professional, or the software used by the preparer, will re-allocate or re-balance both the existing funds allocated towards a component, and the contributions from that point forward added to that component. Both are essentially insignificant. If it is found that the Roof project will be more expensive than anticipated, it is typical that funds will be re-allocated towards roofing from other components. This is what the “Cash Flow” method does on an ongoing basis.

So the amount in the “Roof Reserves” shouldn’t matter. What matters is if the Funding Plan provides for the timely repair and replacement of scheduled Reserve projects. Focus on the big picture, not on numbers that are somewhat arbitrary from year to year!

    Hi and thanks for taking the time to explain the terminlogy for the newcomers!

    The building is an 8 unit condo building. The steel roof, is warranted for 50 years.Would you setup a reserve to cover estimated replacement at the 50 year mark, using an inflation rate of 2.6% annually?

    • Jack – interesting. We just finished a Reserve Study with a metal roof issue. The boardmember was adamant that it would last “approximately 50 years”, but it is our Reserve Study, and in our professional opinion we felt a good expectation was for a Useful Life of 50 years with a Remaining Useful Life of 25 years (the property was approximately 25 years old). A roof system meets the National Reserve Study Standards four-part test for a Reserve component, so we recommend it be included. Without knowing the particulars, 40 or 50 yrs should be a good estimate for Useful Life. In the absence of any physical evidence of deterioration that would guide your decision-making, subtract the age of the roof to get a Remaining Useful Life figure. An inflation rate of 2.6% is reasonable.

      Make sure all your Reserve Components are included, and revise/update your Reserve Study annually so you never “get behind” on contributions, and so the owners always have an accurate understanding of the size/strength of the Reserve Fund.

      Please contact me directly if you have further questions.
