How’s your roof after the hot weather?
We had sunshine reaching the upper 90s during early October. Prolonged heat can weaken shingles, sealants, flashing and roofing membrane.
That’s why Garvey Roofing installs and repairs roofs for all seasons. Here’s an easy way to prepare for the upcoming winter rains.
Older roofs need a close look
If you have an older home, try to gauge the health of the underlayment. Garvey Roofing has repaired and installed roofing on historic homes so you can maintain the character and have the modern-day protection you need.
Inspect newer roofs
Make sure your roof has adequate drainage and ventilation.
Garvey Roofing ensures all homes have proper ventilation to circulate air and reduce heat in the summer. In the winter, circulating air keeps attics dry.
Commercial low slope roofs need care
The commercial roofs you see along Lake Avenue in Pasadena or along Foothill Boulevard in our local cities need to have proper drainage and the roof shouldn’t have ponding water.
Make sure HVAC systems are properly sealed.
Garvey Roofing also knows how to install commercial roofs with interior drains.
If you had leaks last year
Not every leak means you need a new roof.

When should you plan to replace your roof?
Consider this:
- The age of your roof
- The current condition of your roof
- And how long you plan to own your home or commercial building
If your roof is old, shows signs of wear, and you plan to own your home or commercial building for longer than a decade, then a decision to install a new roof can be a wise financial decision.
A new roof using today’s technology can reduce utility bills, add curb appeal, and protect your roof for many decades.
Materials and labor costs typically increase year after year. Deferred maintenance becomes expensive so it’s best to replace a roof before there’s interior damage and costs continue climbing.
