ROOF MAINTENANCE
PROGRAM
This
document contains a brief discussion on the ROOF SYSTEM program used by PMS
Roofing to maintain our customers roof inventory. The program has reduced roof maintenance expenditures by 65% at
local institutions similar to yours.
I’m sure the program will perform equally as well for you.
General Information
The
PMS ROOF SYSTEM is an engineered management system (EMS) designed to evaluate
built-up and single-ply roofs. It is a decision support tool that provides
systematic and consistent methods of assessing roof condition, selecting repair
and replacement needs, and prioritizing work based on maximizing benefits and
minimizing costs. The program was developed by the
U.
S. Military for use at their all of their bases worldwide.

The ROOF SYSTEM program.
The
ROOF SYSTEM is comprised of network inventory, condition inspections, and
network and project-level management. The ROOF SYSTEM allows PMS to efficiently
manage its customers database, small or large. The program stores inventory and
inspection data, performs index calculations, analyzes data and generates
customized management reports.
Benefits of Implementing and
Using ROOF SYSTEM program.
·
A
roof inventory that is organized and easily accessible
·
Objective
and consistent condition evaluation of built-up and single-ply roofs
·
Systematic
and documental engineering basis for determining needs and priorities
·
Identification
of budgeting requirements for maintaining roofs
·
Cost
analysis technique for selecting repair/replacement alternatives
·
Rapid
access of stored information
·
Small
roof problems are detected and corrected before they become costly replacement
projects
·
Tremendous
cost savings
Life Cycle Costs
In
addition to the previous benefits, the ROOF SYSTEM enables any business to save
time and money that was previously spent on costly roof replacements. Roof
repairs are much more economical than roof replacements. Roof repairs range
from $.05 to $.15 per square foot per year, whereas roof replacements cost from
$3.50 to $7.00 per square foot. With regular maintenance your built-up roofs
should last 20 years or longer. Without an effective program, they may only
last 5 to 12 years.
Components of the ROOF
SYSTEM program
Network Inventory
The first step in implementing the ROOF SYSTEM program is to develop an
inventory of all the built-up and single-ply roofs that the agency is
responsible for maintaining. The building roofs are divided into smaller units
called "sections". A roof section is the base unit upon which all
repair and replacement decisions are made. PMS collects physical and historical
information about each roof section, including the physical dimensions,
construction characteristics, and material types of each roof component (deck,
insulation, membrane, surface, and flashing).
Condition Inspections
To evaluate the condition of built-up and single-ply roofs, an objective and
repeatable rating system for determining the roof's present condition is used.
This is accomplished by means of a visual inspection were deficiencies are
cataloged into three (3) categories:

Blisters in a seam.
·
Repair of medium-level deficiencies will improve the
performance of the roof system and extend its service life.

Upon completion of the inspection, the quantities of the roof distresses are entered into ROOF SYSTEM database. To ensure objectivity, condition indexes are used and the membrane, flashing, and insulation components are evaluated individually. This system insures an objective assessment of component condition, waterproof integrity, and repair needs. In this way PMS is able to objectively assess the overall condition of a roof section and thereby determine its Roof Condition Index (RCI). The condition of the roof systems insulation is determined by conducting roof moisture surveys using methods such as infrared scanning, and nuclear and capacitance metering to identify areas of wet roof insulation.
Network-Level and
Project-Level Management
Once a database has been established and the condition of the roof network is known,
network management can be utilized. PMS can establish current and future
budgets for repair and replacement of roofs in the network. The ROOF SYSTEM
program generates several reports that greatly reduce the time and effort
necessary to make sound engineering decisions.
These reports can be presented in a conventional format or graphically
using advance special graphic information systems (GIS). The data can even be stored on a secure
Internet site for your convenience. The ROOF SYSTEM program performs cost
analyses on repair and replacement alternatives to determine the optimal
strategy for each network. Thus, The necessary documentation for supporting
work requests for individual projects is generated.
Graphical
representation of inspection data allows for a quick appraisal of the
entire inventory status.

Using
this program PMS Roofing has been able to reduce our customers roof maintenance
budgets by as much as 65% while simultaneously extending the service lives of
their roofs. I would enjoy the
opportunity to review local case studies of our satisfied customers with
you. If you have any questions please feel free to contact me 561/394-8012.
