Weather Restrictions: Asphalt Shingles

. WEATHER & RENOVATION is a joint project of: CTV.ca and JonEakes.com designed to help you plan home improvement projects around weather restrictions. If you have just been checking the weather for your project on the CTV web site -- welcome to JonEakes.com where you will find all the details for your home improvements. If you started here and are looking for weather restrictions related to home improvements, follow this link to CTV.ca where you can get your local weather forecast together with weather restrictions for specific products  on the bottom of the page.

********************************

Organic base and fibreglass base asphalt shingles have the same weather restrictions. When it is cold you have to be careful not to fracture shingles and pneumatic nailers need to be adjusted to not punch through the shingle. When it is hot you have to be careful to not tear a shingle and minimize walking so as to not scrape off the protective granules. Click here for details on WALKING ON SHINGLES. If there is any possibility of rain during the roofing job, plan for the quick ability to cover any exposed part of the roof with a large tarpaulin -- you don't want to replace the ceiling below as well as the shingles. However the minute the last shingle is placed to protect the roof, rain will do no harm. If you must work in threatening weather, many people will place that tarpaulin on the ridge ready to roll out and only remove it when it gets in the way of placing the last shingles. An important detail that many people miss is that every shingle has a little application of adhesive already on the shingle, designed to end up right under the bottom edge of the next shingle tab. When the sun shines on a newly shingled roof, the shingles relax and lay flat onto that bit of adhesive and the sun activates it. Once that is done those tabs will no longer have a tendency to lift with wind. If you shingle very late in the fall, the tabs may not be adhered down until spring, and a very windy storm that blows off all the snow could lift the shingles. The stronger the wind gusts in your area, the more important it is to complete a roof earlier in the fall while there is some heat left in the sun. Just about the only adhesive we might use with shingles and flashings is PLASTIC CEMENT. As for the question of the difference between organic base and fiberglass base asphalt shingles, as well as a warning about shingle standards in a cold climate, check out WHAT IS CSA CERTIFICATION?
