Silver Spring Roofing: Article About Extreme Temperatures and Roofing Materials
When homeowners schedule a roofing project, they usually select seasons with calm weather conditions, such as spring or fall. Sometimes, it's not possible to wait until these seasons, leaving the extreme heat and cold to affect the project's materials. Although shingles, underlayment and other materials are resilient against weathering when properly installed, adding them to a roof under difficult conditions compromises their durability. A Silver Spring roofing professional must alter certain installation procedures when it's hot or cold outside. Homeowners will notice a marked difference with professionals' rooftop strategies as well.
Extremely cold conditions can occur during almost any season except summer. Snow, icy rain and temperatures below 26 degrees make any installation nearly impossible. If the roof is clear of snow or other debris, however, an extremely cold installation can occur. Experienced contractors can be seen walking carefully around underlayment and shingles. Temperatures in the 20s and 30s make roofing materials brittle. If a roofer's footing is too heavy on the materials, they can literally crack from their brittle texture. Even nailing the shingles to the deck could result in cracked materials from the shock of hammering. Roofers must be extremely careful in these cases.
In contrast, hot conditions pose issues for the shingles' adhesive strips. As roofers lay the shingles out, they slightly adjust the materials' orientation as a row is installed.

With hot conditions, however, the adhesive backing can stick too quickly to the roof deck. Shingle orientations could be compromised, requiring a complete rework of the area by professionals.
Metal flashing must be used around roof penetrations, including chimneys, to maintain a leak-free surface. When metal is installed in hot or cold conditions, it expands and contracts with the prevailing temperatures. Although contractors could have installed the metal properly, the normal temperatures setting in after the installation could cause the materials to shrink or enlarge. Leaks could easily occur in these instances.
Homeowners should also note that extreme temperatures create poor conditions for workers' bodies. They'll need to take more breaks throughout the day to remain healthy. Heat exhaustion and hypothermia are possibilities in extreme heat or cold, respectively.
From checking the rafters to measuring flashing contraction changes, working with extreme temperatures on the rooftop will slow some installation times down. Contractors should communicate any timing issues with the homeowners so they're aware of any changes. Ideally, it is best to wait until outside temperatures are comfortable to ensure a rapid roofing installation. Roofers who are comfortable can work more intensely and for longer periods with calm weather conditions.
