Did you know that most caulking should not be applied below 5 degrees Celsius? One of the most common construction adhesives, LePage, PL 9000 should only be applied above 10 degrees Celsius.
Caulking is used for eaves troughs/gutters, window and door sealing and chimney flashing. Construction adhesive is used everywhere.
There are certain measures that can be taken to help the curing process, but you can see that there are optimal seasons for the best end result.
Like caulking and adhesives, mortar which is used for masonry and brick work needs to be above 5 degrees Celsius or special precautions such as hoarding with heaters is required for protection to properly set. Now you know when a good time for that chimney repair is. Any time is good, but hoarding and heating is not cheap.
Concrete needs the same precautions as mortar. Some hoarding or boundary layer with heating is required to protect your curing concrete. If you are using heaters with a flame then a fire watch is required. That's a large expense for a 3 day cure time.
I am often amused and upset when I see contractors performing paver / interlock installations in the winter. Since the longevity of these installations is all about base preparation there is no reasonable way a proper base can be acheived in a winter climate. I've seen installation below -10 degrees Celsius happening. I don’t see how a base preparation can be achieved with frozen ground and with fill material that contains ice and snow from the storage yard. Once the ground thaws the "compacted" base layers will have the ice and snow thaw out compromising the integrity of the base.
Unless you are in need of an emergency roof repair, it is advised to hold off roof work until the weather warms up. Underlayments do not stick to roof decks as well, sealing strips don’t seal as well and roofing cement is not that mallable. Roofing nails shooting through a cold shingle may not form a proper seal. Cold shingles may crack and tear while handling. When sealing flashing around roof penetrations such as chimneys the caulking will not cure properly.
Just know that there are optimal times for these types of work. Contractors are slower in the off season and are looking for filler work. Make sure that you are getting the best shot at longevity for your project by being informed about its limitations. Ask your contractor a lot of questions about your concerns and demand an intelligent answer. Answers like "we do it all the time" should not instill confidence.
