First off let’s remember safety. The whole family, including pets, should be kept indoors. The job is very noisy and if you work from home you may consider working elsewhere for the duration of the job. Remember, everything used to reroof your house needs to be as close to the house as possible, this requires access to your yard and driveway. Please move anything of value away from the house, things such as furniture, grills, statues, glass globes, flower pots, or any other fragile item that can be broken. All vehicles should be removed from the driveway and out of your garage. They should be parked on the street or in a neighbor’s driveway.
Trash will be thrown off of the roof and be present in the lawn prior to clean up. All debris will be removed from the premises before the job is done. It’s a good idea to cover all valuables in the attic and garage, debris and dust will most likely enter these areas. Remember to turn off any roof or attic fans. Any satellite dish mounted on the roof will need to be removed and reset. Your satellite provider will need to re-calibrate the signal.
Remember to use a company that inspects the job before, during, and upon completion!
As a general rule we like to wait until the high will be in the forties, but in some circumstances we will roof in cooler weather. A roofer working in forty degree weather is a happy roofer. They are not rushing to get the south side done before the sun turns it into an incinerator at 1 p.m. like they are in July, and the work day is shorter so there is less fatigue.
One advantage to cool weather roofing is the avoidance of foot fall. Foot fall is the scuffing and granular loss caused by a roofers foot sliding across a shingle that is very hot and thusly more pliable. This footfall significantly shortens the life of a shingle. This is also why roofing in extremely hot weather is also unadvisable.
In summary, the positives of cool weather application are a happy roofer, who isn’t damaging the shingles, who is not in a hurry, and doesn’t work from 6am to 9 pm (because it’s dark!).
