Cat on a Hot Tin Roof — Well, Shingles
It seemed fitting to refer to this famous Tennessee Williams play from 1955. Shingle and tile roofs get hot, too.

If you have an older roof, then summer heat is bearing down and degrading the materials.
Adhesives on shingles will loosen and let the rain seep in during winter.
Summer’s heat on a roof = less protection against rain in winter. When leaks occur, wood breaks down and you the risk of leaks inside your home or commercial building.
Installing a new roof in summer will mean your air conditioning works more efficiently in the summer and your heater doesn’t have to work as hard in the winter.
In the summer, doing basic repairs and reducing heat transference into the house reduces the chances of leaks in winter.
Here’s what to look for. Make sure vent protrusions and rooftop HVAC units are properly sealed. Secure any missing shingles, especially ridge caps.
Keep the Air Flowing
Thomas Garvey knows how to keep the roof’s surface temperature as low as possible. The underlayment plays a key role in how a roof handles the sun’s heat.

Protect against the sun’s most damaging rays
Garvey Roofing can install Therma Sheet which reflects most of the sun’s harmful UV rays back into the atmosphere. This lessens the amount of heat transferring into the attic.
Attic fans and low-profile vents are excellent tools for keeping attic temperatures as low as possible. A long-lasting attic fan that services a house of 2,000 square feet may cost less than $150. It can be programmed to kick on when the attic temperature hits a specific mark like 100 degrees.
The attic fans draws out hot air from inside.
Low-profile vents do the same but they rely on heat rising up and out of the attic.
Homes in northeastern Los Angeles County don’t get the same amount of summer sun because of the micro-climates that impact heat.
Neighborhoods in Arcadia and Sierra Madre above Foothill Boulevard could have a much different reading than homes in Alhambra on in the western parts of Pasadena and Altadena.
Trees make a big impact.
How exposed is your building to either the morning sun or late afternoon sun when the temperatures peak? The more exposure then the more you need to watch for damage from the sun and have a plan to keep heat from transferring in.
