Take the basic steps to prep your commercial roof for winter rains and summer heat
Thomas Garvey says they repair and install new roofs for all seasons because summer heat and winter rains act like partners. Here’s how:
Summer heat damage
A roof’s surface can dry and crack due to the intense heat.
Roofing membrane’s can shrink or pull at the seams.
Are you familiar with older RVs that needed protection from the sun? The heat and UV rays damages the seams and leads to leaks inside during rainy weather.
Older cool roof coatings can deteriorate.
Exposure to the sun can lead to a series of problems that need attention.
Potential roofing problems
These conditions can lead to leaking roofs:
Ponding water on flat (low slope) commercial roofs
Cracked membranes
Loose flashing
Thomas Garvey or one of his team members will let you know the condition and if repairs are possible.
Check drainage systems
Clear all drains and gutters.
Check that downspouts are directing rain flow away from the building’s foundation.
Inspect HVAC systems on roofs to make sure they’re not creating overflow problems.
Also inspect interior drains to ensure that they’re properly sealed.
If your roof is in good shape for this winter, then that’s good.
Use November and early December to plan ahead for capital projects in 2026 or 2027.

Why Garvey Roofing?
Thomas Garvey is honest. He’ll never stick customers with unnecessary expenses.
I learned this first hand when I asked him to remove and replace my attic insulation after the Eaton Fire in Altadena.
We had a vendor for our home insurance say that the insulation needed replacing. Companies were going to charge from $ 8,900 to $ 10,000.
Thomas sent his crew with their machine to do blown-in insulation, but they looked inside my attic and said I had the best insulation on the market and that it was clean overall.
They recommended that I leave the insulation alone and Thomas explained why my indoor air quality would remain fine.
He saved me several thousand dollars by being honest.
Thomas Garvey has operated Garvey Roofing for over 35 years. He started roofing around Monrovia as a teenager and launched his roofing company after serving in the military.
