Why Roofs Matter More in a Sacramento Summer

Most homeowners we speak with say “It’s not raining so why should I worry about my Sacramento Roofing?”. We will explain what the brutally hot and bright Sacramento sun does to your asphalt shingles. What heat can do when it builds up in your attic. Summer roof heat also affect your HVAC efficiency if your attic ventilation is inefficient.

When Is Heat Good For A Roof?

Right after the new roof is applied, the heat helps seal the shingles and bond them together for a tight, leak-free, cohesive unit. However, it an be bad during the installation and we will explain why.

The sealants need to be pliable when first laid down to help them begin to bond. But, during that process, it is not safe to be working on the roof because they can cause the shingles to slip and tear under the workman’s foot steps creating a dangerous condition. Not to mention if the small tears and movement goes unnoticed during the roofing process, it could lead to premature leaks and failure.

This is why during very hot Sacramento roofing days, you’ll see the crews pack it up before noon allowing what progress that has been made, seal up and create that bond over night. A moderately hot day, say around 85 degrees helps the shingle’s thermal bond and helps them lay flat. Asphalt shingles that have bonded overnight are then safe to walk on and progress to continue.

Okay, So Heat Is Good In the Beginning – What About Months and Years Later?

High quality GAF Timberline HDz shingles are designed to last 30 years and longer. The lighter the shingle color, the less susceptible to heat it will be. This is due to the ability to reflect light rather than absorb it. It’s why lighter shingles are called “cool roofs”. Choose a lesser quality 3-tab roof shingle and expect a lifespan of less than 20 years.

Regardless, with all asphalt shingles, here are some the effects of relentless heat from California’s blazing sunshine:

• Distortion and Softening: Walk across the street barefoot in the summer and you’ll quickly learn that asphalt absorbs heat! Since asphalt is a primary component of shingles, heat will soften them over time. In older roofs, the shingles can curl up, lose rigidity and shape. A warped, misshapen roof shingle can introduce water intrusion, introduce molds, and be more susceptible to wind.
• Thermal Expansion and Contraction: Sacramento roofing experiences persistent swings in temperature day after day. This expansion (with heat) and contraction (when cooled) is actually movement which can, over time, lead to small cracks. The process can cause the shingle to break away from the nails and be susceptible to blowing off in strong winds.
• Granule Loss: Asphalt shingles have a protective coating of tiny mineral granules designed to reflect UV rays that would otherwise directly attack the asphalt. Over a period of climate changes, your roof will experience granule loss. You can see evidence of this when you clean your gutters or at the point of your drip line near the foundation. Loss of granules means faster degradation of the asphalt.
• Gutter and Downspout Health: The ability of your roof to shed water is dependent on your gutters and downspouts being clutter-free. If water backs up at the eves, water can begin to penetrate the soffit area. Clogged gutters prevent the roof from efficiently shedding water.

Those are the primary contributors to premature aging and the failure of an otherwise quality Sacramento roofing job.

What Are Some Other Effects Of An Aging Roof?

Besides the roofing shingles, here are some other things to consider on Sacramento roofing:

• Attic Ventilation: Having adequate ridge vents and soffit vents are critical to the life of your roof. When the attic gets hot, hot air rises and escapes through the ridge vent. The rising hot air draws cooler air through your soffit vents creating a ventilation system. If the process is ineffective, heat builds up in the attic and contributes to shingle and other roofing material degradation by heating it from below. The problem is exacerbated by the combination of heat above from the sun and heat below from the hot attic.
• HVAC Strain: While not a direct contributor to roofing shingle degradation, a hot attic without adequate insulation will radiate heat down into your home…it has no other place to go. The result is your HVAC has to now work overtime to keep your home comfortable.

Now that you have determined that the roof on your Sacramento home might need a replacement, here’s what you should look for.
