Commercial Roof The best way is to do it right. Stamford Westport
We have been installing and making roof repairs in Stamford, Darien, and Westport for over 25 years.
The most common problems on Commercial Roofs are:
- Ponding or standing water.
- Clogged strainers over internal drains.
- Clogged scuppers that protrude through a parapet wall.
- Drains are not located in the right areas.
- Edges are higher than the roof preventing water run-off.
- Air Conditioner curb flashing.
- Vent pipes and scuppers.
Other problems are also common as in flashing, air conditioner curbs, vent pipes and drains that could be causing leaks.
In the olden days, half pipes were used to cover a parapet wall.
Those days are over and the best is to remove them and replace it with aluminum metal edging.
This commercial roof had several problems before we got to it.
An EPDM rubber roof was installed 5 years prior to our roof installation. Again the EPDM roof did not last.
Most EPDM roofs don’t last that long due to the adhesives that were used to glue it down. The EPA have now ruled that the EPDM roofing industry can not any longer use the contact cement adhesives due to environmental and toxic problems. Therefor EPDM roofers have to use new untried methods to adhere the rubber to the sub roof and the seams.
It takes 10- 15 years before any system can show its weaknesses. Unfortunately, homeowners and businesses are the guinea pigs to be used for this trial period.
We removed the half pipes and installed 2 scuppers towards the back of the roof.
You can see a comparison in the images above and below where we removed the half pipes. It is a much better system that will last forever. We also closed the old drains and installed 2 scuppers through the parapet walls. No more drains to clog.
Notice how much better the roof looks after the half pipes were removed. It is also obvious that the scuppers are practical than drains in this case.
This roof was just completed when a rain storm came over. The water was still draining off when the picture was taken. We used a rubber roof membrane with white granular that is reflective to help reduce the heat in the building. The granular surface also protects the material against ultraviolets. This will make the rubber roof last 25 – 40 years. Unlike in EPDM rubber where the material is black and have no protection.
