If your roof is leaking, you're probably anxious to get it replaced as soon as possible. If a big storm is on the way, you may wonder if the roofer can get the work done in time. Each job is different, so it's difficult to estimate how long it will take to put on a new roof, since several factors affect how the work progresses. If all goes well, the roofer may be able to get finished in a day or two, but sometimes it takes much longer. Here are some things that affect how long it takes to put on a new roof.
Tear Offs Take Extra Time
Sometimes roofers put a new roof over an old one. This eliminates the need to spend time ripping off old shingles. If you're having a total roof replacement, expect the work to take longer. The original roof has to be torn off first. Then the contractor has to build the new roof up from the deck. If the deck has rotted, it may need to be replaced too. These are all very important steps that you wouldn't want bypassed, so the extra time prepping for the new shingles is worth the delay.
Steep Slopes Slow Down Work
If the slope of your roof is very steep or if your house has multiple levels, the crew will need to use extra safety equipment. Wearing a safety harness prevents injury from sliding off the roof, but it does require a little extra time to set up and move around. Plus, on a steep slope the crew has to move much more carefully so no mistakes are made that cause slipping and falling. If you have a typical ranch-style home with a low-sloped roof, the crew can easily balance themselves on the roof and work at a quicker pace.
The Weather Controls The Pace
The single-most controlling factor of how fast your roof gets finished is the weather. The crew can't work on the roof when it is raining, even if it is light rain. They can't go back on the roof until it is dry because a wet roof is slick. Lightning is another concern. Lightning often strikes miles ahead of a storm, so if bad weather is approaching, the crew may wrap up work so no one is at risk of getting struck by lightning when standing on the roof. Roofers don't wait until the last minute to knock off work because they need to make sure everything is covered and protected by the time rain comes. Therefore, even a short period of rain can stop work for several hours. If you are unlucky enough that the roofing work starts during a rainy spell of several days, it could take days to complete your roof.
Besides all that, other factors such as the square footage of your roof and the number of workers in the crew come into play. When you get an estimate for your replacement roof, the contractor will give you a general idea of how fast the roof can go on under ideal conditions taking all the factors into consideration. Just be aware that a turn in the weather could bring an unavoidable delay.
