Here’s how to make your home watertight so rain doesn’t seep into your interior and cause buckling and cracking in your stucco walls or your home’s foundation.
Rain is always welcome and helps fruit trees, flowers, and lawns from La Canada to Azusa and throughout the San Gabriel Valley. But the place you don’t want rain water is seeping inside your home’s walls and along the foundation.
Moisture causes bubbles to form and cracks in your exterior paint and causes premature aging in your home.
Let’s keep the rain where it belongs: on vegetation but not in our homes.
Where do you begin?

How a roof stops rain
A roof is a system composed of these roofing materials: decking which is typically plywood, underlayment, and the covering which is usually asphalt shingles, tile, metal, or slate.
Garvey Roofing is a local roofing contractor based in Monrovia and working throughout the San Gabriel Valley that approaches every job as a craftsman using the best materials.
That includes the underlayment. Garvey Roofing uses Therma Sheet which reflects the sun’s most harmful UV rays even though you never see it because it’s placed beneath the top roofing layer.
Now, here’s something to note: sun beating on the roof weakens roofing seams and seams around metal flashing. Sun degrades roofs with older asphalt shingles and the rain washes away the protective granules.
This is how summer sun and winter rain create a vicious cycle.
And this is why Garvey Roofing installs new roofs and repairs roofs for all seasons, installing a system that keeps your home’s interior dry in the winter and cool in the summer. A roof that’s properly installed benefits the environment and your budget as a homeowner.
Part of the roofing system includes ventilation to keep air flowing in the attic using low-profile vents and an attic fans, if necessary.
How about gutters?
Gutters are great for channeling water from the roof and carrying it to a drain so water doesn’t pool around the foundation and seep into the walls.
Garvey Roofing can install seamless gutters that are properly tucked under the drip edge so they won’t leak.
Let’s talk paint
Why would a roofing company also paint? The right exterior paint not only looks good but also protects walls from excess moisture and the blazing sun.
Again, Garvey Roofing looks at how you’re impacted all year long in any type of weather.
Capture rainwater
Did you know your roof can harvest rainwater and reduce the amount of water you need to irrigate?
Get the most out of your roof and put it work in creative ways.
Garvey Roofing can install a rain capture system or build a custom solution that looks great and fits in with your yard and home’s design.
