A commercial roof replacement is a big job, especially if you have a large building. Even if your building is small, putting on a new roof can be disruptive. Your roofing company will try to keep your old roof going as long as possible, but at some point, the old materials need to come off so new roofing can go on to prevent water damage to your building. Here's a look at what's involved with a commercial roof replacement.
Detailed Planning Is Necessary
A lot goes into a commercial roof replacement. First, you'll need to decide on the type of new roofing to put on. If you are happy with the way your old roofing held up, you may want the same for your new roof. However, if you want a roof that's more durable, talk to your roofer about options.
You and the roofer will also plan how to go about the process of tearing off the current roofing and putting on a new roof with the least amount of disruption to your operations. If the old roofing has to come off, there will be debris being tossed around, so you'll need to keep the area clear of employees while the work is going on.
The roofer might agree to work on days you're closed or at slow times, even if it takes longer to get the roof replaced. The roofer might work on a section of the roof at a time so no part of the roof is unprotected during the process.
Tear Off Old Roofing Down To The Deck
Part of the reason a commercial roof has to be replaced rather than repaired is when the insulation boards under membrane roofing are saturated with moisture. When that happens, the roofing and insulation boards have to be torn off and thrown in a construction dumpster.
Your roof might even have two layers of roofing on it, so if there is another membrane under the insulation boards, all of that roofing has to come off too, down to the roof deck. Then, the deck can be inspected and replaced where necessary so the deck is dry, strong, and stable.
Apply The New Roofing
A commercial roof replacement could take several days to complete, even though membrane roofing is fairly easy to install. However, once all the old roofing is torn off and out of the way, the process may not be as loud and disruptive when it's time to install the new roofing.
One decision you make during the planning process is how the membrane will be attached to the roof. Sometimes, screws are used. The membranes can also be glued to the roof. Membrane roofing can even be held down with gravel if you prefer.
The membranes are placed on the roof and the seams are bonded together, and then they are attached according to the method you choose. Installing a new roof membrane goes fairly fast when compared to pulling off all the old roofing, so you should get back to your normal operations as quickly as possible once work starts on the new roofing.
