DON’T EXPOSE YOUR BUILDING INTERIOR TO THE ELEMENTS; AVOID TEAR OFF
As many building owners have found, to their dismay, over the years, most roofing systems require tearing off the old roof before the new system can be installed. This means that the inside of your building will be exposed to the elements during the course of the project. There have been times where rain snuck up on a roofing contractor while they had the inside of a building exposed, and before you know it there is ponding water of the inside of the building. This is obviously not a good situation. So, how can you replace your roof without tearing off the old one and exposing the inside of your building to the hot, cold, rain, or snow? There are 3 ways to avoid tearing off your roof; which means you save time, money, and avoid exposing the inside of your building and it’s occupants to the weather:
Add a Second Roof
This method can only work one time before a complete tear-off is required, but it works well for that one time. It is really just a way to temporarily avoid tear off, not a way to permanently avoid it. This is where you go in over top of the existing roof and install a new system directly over top of the old system. You don’t have to tear off the old roof, you simply install the new roof right over top of it. You will probably have to make some structural changes to make sure the new roof is properly installed and adhered, but you won’t have a huge gaping hole in your roof for any period of time.
However, once you’ve installed two roofs on your building, you are no longer permitted by law to install another roof over top of the existing system. You cannot have three roofs on your building. But, you also can’t just tear off one; you have to go back and tear off both roofs – exposing the inside of your building to the elements – before you can install a new roof. So, this is really just a temporary avoidance of exposing the inside of your building to the elements rather than a solution to the problem.
Install a Spray Foam Roof
Another good alternative to tearing off your roof is to install a spray foam roof over top of your existing roof. In most cases, a spray foam roof can be installed directly over top of your existing roof, as long as it is clean and dry. The foam fully adheres to your existing roof and provides better insulation, waterproofing, protection from wind uplift, and reflectivity than most roofs do. So, not only do you avoid tear off, you also get a roof that is superior to your old roof in most cases.
On top of it’s quick and painless installation and performance once installed, spray foam offers you the ability to recoat your roof every 15-20 years and receive a brand new warranty. This recoat once again prevents the need for tear off, so your building will still not be exposed to the elements.
Restoration coatings are installed in a manner similar to spray foam. though their performance is quite different, both systems help the owner to avoid tear off. Almost any existing flat roof that is clean and dry is a candidate to receive a new coating over the roof. Once a roof is ready, simply spray or roll-apply the coating directly onto the existing roof. This will create a seamless, waterproof membrane over the existing roof and you were able to avoid tear off during installation.
Restoration coatings aren’t a great option for roofs that aren’t structurally sound or for someone looking to greatly increase their R-value, but if you’re looking for leak protection and a warranty, a restoration coating is a fantastic option that can save you money and keep your building safe and covered. The owner of a roof that isn’t structurally sound probably can’t avoid tear off; that roof needs to come off for the safety of everyone in the building.
