EPDM Roofing
EPDM: 20 Years Old
There are a number of flat roofing systems available, some of which include EPDM (Ethylene Propylene Diene Monomer), and Modbit (Modified Bitumen). While each has its advantages and disadvantages, these are two of the more common systems used in residential and commercial applications today.
Modified Bitumen is a common flat roofing system that consists of asphalt with added modifiers to give it a rubber-like quality. Modbit membrane rolls come in 36”-39” widths, and cover an area of approximately 100 square feet. Surfacings can include mineral granules, copper, aluminum, or aggregate. Modbit systems are usually one, two, or three-ply systems and are typically torch-applied. Installation costs are less than most single-ply systems on the market today. Modbit is available in a variety of colors, whereas EPDM is typically limited to black or white.
Since most modbit systems are torch-applied, the roofs may experience leaks when the proper moisture barrier is not installed underneath the coping cap on parapet walls. Other typical problems with this system include inadequate head laps and backwater laps which allow moisture infiltration. Effects of backwater laps are leaks and blisters which can lead to roof failure. Even cold-applied modbit systems can result in moisture infiltration as well as under application of adhesive which can result in poor lamination and roof leaks.
EPDM is a single-ply, flexible rubber roofing membrane that can easily be cut to size to fit any job. This system can either be full-cured prior to installation, or can be left to cure during natural weathering after installation. The most common application procedures include fully-adhered, mechanically-fastened, or loose-laid. The first method uses water-based adhesives to adhere the rubber to the substrate. The second method is attached by using manufacturer-approved mechanical means to the substrate. The third method involves securing the membranes only at the perimeters and any penetrations. EPDM roofing systems are usually sealed using adhesive or splice tape.
EPDM can be installed in a single piece, eliminating problems with parting joints and roof leakage. It also does not crack, peel, or split, and is resistant to atmospheric pollution. Its high percentage of elasticity allows it to stretch to over 300% to accommodate temperature change and building movement. The approximate life expectancy for an EPDM roofing system is around 20 years, with little to no maintenance required.
Both EPDM & Modified Bitumen offer benefits to the flat roofing industry. Modbit tends to be less expensive and offer more aesthetically appealing options, while EPDM is more environmentally friendly, easier to install, and tends to have a longer life cycle when installed correctly.

Sewer Line Belly and Pipe Channeling Explained
What is a Sewer Line Belly?
A sewer line ‘belly’ is defined as a pipe holding water due to inadequate slope percentages at one or more sections of the lateral drain. A belly in a sewer line is often caused by geological events (soil movement/erosion), foundation settlement, inadequate soil compaction during installation, or a combination of various factors. Often, pipe bellies do not cause immediate or complete failure of the sewage system, however, bellies become problematic when/if debris collects and causes system blockage or backup.
What is Sewer Line Channeling?
Sewer line channeling occurs when running water cuts a course into the bottom of a sewer line over time (similar to the formation of a ravine, canyon or gully). In many cases, by the time a sewer line channel has become a problem, the bottom of the pipe may be in a state of failure. Failed or significantly deteriorated pipes (often discovered in dated cast iron drain pipes) provides an access point for tree roots, soil, and insects which typically lead to additional issues and complete drain line blockage.
What Are the Repair Options – Bellies?
Often, pipe bellies do not cause immediate or complete failure of the sewage system, however, bellies become problematic when/if debris collects and causes system blockage or backup. In most cases, it is not possible to determine if pipe settlement has stabilized or is ongoing. Due to this limitation, the possibility of increasing drainage flow disruption and future repair needs at seemingly inconsequential bellies/sags can not be ruled out. Professional opinion and repair/replacement recommendations to address pipe bellying will vary from one specialist to the next and is often decided on a case-by-case basis (primary repair option is pipe excavation and replacement).
Due to the inability of a home owner or maintenance specialist to regularly monitor portions of buried plumbing, a proactive approach to addressing sewage system issues is considered to be a best practice and proper preventative maintenance care.
Typically, recommendations to address pipe bellies are based on the degree of drainage disruption, the likelihood of increasing/future issues, and various additional factors relating to plumbing issues/concerns. Professional investigation by a plumbing and/or building science specialist will likely be required to verify issues and determine what courses of action are available and warranted.
What Are the Repair Options – Channeling?
Channeling is often associated with dated pipe material (cast iron). Professional opinion and repair/replacement recommendations to address pipe channeling will vary from one specialist to the next and is often decided on a case-by-case basis. The primary repair option is pipe excavation and replacement, however, in certain cases there may be alternative repair options (see link below). If channeling has occurred due to excess deterioration and failure of dated pipe material at multiple locations, full replacement of sewage piping and updating to PVC is likely the most feasible option.

- Check the filter pressure and backwash if necessary
- Shock the pool at least once every 2 weeks to eliminate contaminants and restore clarity to the water
Monthly Pool Maintenance:
- Test the calcium hardness and adjust accordingly
- Test the total alkalinity
- Clean the filter using chemicals
- Inspect equipment such as pump and filter for proper functioning
- If your pool has a liner, inspect the liner for holes and tears and make any necessary repairs
- If you have a concrete, gunite, or fiberglass pool, inspect for cracks.
- Check all other pool equipment including ladders, handrails, diving boards, etc. to make sure nothing is loose and it is working properly
Annual Pool Maintenance:
Winterize and close your pool by doing the following:
-balance the water levels: pH, total alkalinity, calcium hardness
-lower the water levels to avoid freezing and blow out the lines to remove any excess water
-run the filter continuously for about 24 hours
-drain the pump and filter to remove any water
-Thoroughly clean the pool by vacuuming and removing all debris
-Remove skimmer baskets, ladders, and other exterior pool equipment
-Cover the pool
Whether you complete these tasks yourself or hire a professional, proper maintenance is an essential part of owning a pool. Regular maintenance will help to keep your equipment working properly and it will also help you to achieve a clean pool that is healthy and free of bacteria. This is the best way to extend the life of your pool and get the most enjoyment out of it.
General Pool Maintenance Tips
Check your Filtration System
The filter system removes debris by trapping small particles that get into the pool and do not dissolve. The filter system components are the pump and the filter. The pump is the electrical component that drives the pool water through the filter. Most swimming pool filters use sand, diatomaceous earth (DE) or cartridge elements to filter the water. Be sure to operate and maintain your filter according to manufacturers specifications including procedures to routinely clean and/or backwash it.
Clean your skimmer/pump basket
Your skimmer and pump basket are designed to collect large debris before it reaches the filter. You should empty out and clean these baskets frequently. Failure to remove collected debris often results in poor water circulation, inhibiting maximum filtration efficiency.
Vacuuming
Vacuuming your swimming pool helps to ensure a clean, healthy water environment.
Most manual pool vacuums attach to the skimmer and use the pump pressure to bring debris off of the bottom of the pool through the filter system. *Note: There can be no air in the vacuum hose when using a manual vacuum. Air can be driven out of the vacuum hoses by either submersing the vacuum hose under water or by placing the vacuum hose over one of the return fittings before hooking it up to the skimmer.
Leaf Skimming
Use a Leaf Skimmer attached to your vacuum pole to gather up leaves, insects and other floating debris on the surface of the water. By removing the debris before it reaches your filter system or the bottom of your pool, you can save time, increase filter efficiency, and prevent staining of the pool bottom.
Brushing
Use a wall brush to clean and scrub pool walls and bottom. Brushing the pool will allow debris and dirt to be caught in your pool’s filtration system as well as prevent algae growth and staining due to stagnant dirt. Brush your pool as needed or as part of weekly maintenance.
Keep Surrounding Deck Areas Clean
A good practice in maintaining a clean pool is to keep the deck and surrounding areas free from loose leaves, dirt, and debris. This dirt and debris will either be brought into the pool by the users or blow into the pool where it will have to be cleaned out. A regimen of regularly hosing down the deck or raking the surrounding yard is recommended to prevent needless pool water cleaning.
