REPAIRING A ROOF IN COLD WEATHER
Cold weather, snow and ice make it difficult to work on roofs during the winter. High winds can tear shingles and accumulated snow often causes infiltration into roofs. Thanks to technological advances, however, it is possible to repair a roof, even in winter. It just takes a few more planning and preparation steps.
Precautions to take in winter
Although it is possible to carry out repair work during the winter months, a few precautions must be taken to ensure the safety of workers and the site:
- Snow and ice removal from the roof before and during the work;
- Installation of weather protection structures;
- Use of safety harnesses on sloping roofs;
- Maintenance of access roads to the site;
- Appropriate clothing for workers and protection against the cold
An additional charge of up to 20% must also be allowed for work carried out in the spring, summer or fall, due to the additional work required.
The effects of cold on types of roofs
When repairing a roof in winter, workers are not the only ones to suffer the consequences of cold and inclement weather. The materials themselves require different handling when the temperature drops below zero.
Elastomeric membranes can also be laid in winter. However, there is a significant risk of blistering and frost. To counter these risks, workers must:
- Use an elastomeric membrane suitable for winter temperatures (below freezing point);
- Store materials in a warm and dry place and do not remove them until they are ready for use;
- Completely unroll the membrane and heat it with a torch to soften the framework and expand it;
- Choose a sunny time of day to maximize the efficiency of the installation.
Whether made from TPO or PVC, synthetic membranes can generally set up without a problem, even in cold weather. Indeed, the method of laying these membranes involves mechanical processes and heating instruments. All you have to do is prepare the surface properly and follow the manufacturer’s protocols in order to install this type of membrane.
The use of hot air welding tools allows the installation of the membrane even in very cold temperatures (down to -20 ° C). Materials should still be stored in a warm, dry place. The installation does not require any adhesive which risks losing efficiency below zero.
This type of membrane should not be installed in winter. Manufacturers generally recommend not to proceed with work when the temperature drops below freezing. Indeed, this membrane requires adhesives and materials which must be preheated to maximize the installation in cold weather.
Fortunately, repair work is still possible when the temperature is milder to prevent a worsening of a breakage or an infiltration. To do this, the entrepreneur must:
- Prepare the work surface for removing snow and ice;
- Choose a time of day that is sunnier and more lenient;
- Preheat materials and adhesives;
- Ideally, carry out work when the temperature is above the freezing point
When is the best time to have your roof repaired?
The important thing is above all not to constantly postpone the work. A simple breakage sometimes causes significant and costly problems. Carrying out repair work, even in the middle of January, can therefore be more economical than letting the problem persist.
