Another winter storm is on the way into Los Angeles County and Southern California but now’s a good time to ask, “How do you keep your roof as cool as possible?”
If you need a new roof or want to repair portions of an existing roof, it’s important to know how to keep your roof’s surface as cool as possible.
Do you need a new roof or can you get by with a roof repair?
If the rain washes protective granules off your existing shingle roof and into the gutter or onto the ground, then you may need a new roof. That’s not the only symptom, of course, but here’s why that’s important.
UV granules coat shingles and tile roofs. When the rain washes granules off of older roofs, then that leaves the surface with more exposure to the sun’s most destructive rays and the roof loses its ability to reduce heat transference in and out of the structure.
This is why Garvey Roofing installs and repairs roofs for all seasons.
Heat always seeks the coolest places. In the winter, heat from inside your home is trying to find its way out and the opposite occurs in the summer.
Roofs in the San Gabriel Valley that are older than 20 years can have the seams loosened in the heat which increases the chance of leaking during winter rains.
Shingles and tile aren’t the only components you should be concerned about.
Underlayment
You don’t see it, but it’s an important part of a healthy roof.
Garvey Roofing uses underlayment that repels the sun’s rays and plays a major role in decreasing your roof’s surface temperature on hot days.
Therma Sheet may reflect up to 97% of radiant energy. It’s one of the best ways to reduce heat energy and save on utility bills.
Air flow
Air circulation in the attic helps reduce the roof’s surface temperature. Thomas Garvey will install an attic fan, low profile vents, or both depending on the size of the roof and its exposure to direct sunlight.
Trees provide some shade in certain areas but many homes in cities like Alhambra, Temple City, and Hacienda Heights are directly exposed to the sun from about 9 am until 3pm or later.
Attic Insulation

We use the best R-value for your attic insulation.
Garvey Roofing will insulate attics, too, to reduce heat moving out during the winter or flowing in during the summer.
On other notes, quality windows reduce noise and heat and Garvey Roofing also paints exteriors to protect against the sun’s rays and moisture seeping into exterior walls.
