Call (562) 414-1770Garden Grove is in central Orange County, east of Westminster and south of Anaheim, about 30 minutes from our Long Beach office by the 22 or the 405.

We work on homes across Garden Grove, from small ranch houses to larger tile-roofed homes, plus apartment buildings and commercial roofs. Most calls come from owners who want to know if their roof can make it another few years or if it is time to replace. We give you an honest read either way. Sometimes a few hundred dollars of flashing and pipe boot work buys real time. Other times the shingles are so brittle that repairs would only move the leak a few feet.
1950s and 1960s neighborhoods with a mix of roofs
Garden Grove was mostly agricultural land before it filled with homes in the post-war years. Most houses are one-story stucco ranch homes with gable or hip roofs, re-roofed with asphalt shingle or concrete tile over the years. Some older homes from the 1920s through 1940s remain near the city's original center. Original roofs from the building boom were often wood shake or light composition, and most have since been stripped. A few homes still carry an overlay that hides the old layer beneath.
Apartment buildings, condos and townhomes are common in parts of the city, often with flat or low-slope roof sections. Commercial strips along the main boulevards add many flat roofs. Many homes have additions, covered patios and converted garages with roofs of their own.

Roof problems we see most in Garden Grove
Second-generation roofs wearing out
Many homes are on their second or third roof, and those are now aging. Curling shingles and cracked tiles signal it is time to plan.
Leaks at converted garages
Garage conversions often kept their original roofs. Those roofs were never meant to cover living space and leak at the walls.
Flat roofs on apartments
Low-slope apartment roofs collect debris and pond water. Clogged drains lead to leaks into units.
Decking damage from old leaks
Years of small leaks soften the roof deck. We often replace sheathing sections during a re-roof.
Garden Grove permits and getting the work done
Garden Grove has its own building department, and re-roofs require a city permit and inspection. We handle the permit and meet the inspector on site. For apartment buildings, we coordinate with owners and managers on tenant notices and access.
Garden Grove is inland, so sun and heat are the main stresses on roofs. We focus on UV-resistant materials and attic ventilation. Our crews travel from Long Beach and La Mirada, and we answer the phone 24/7 for storm calls. Most single-story shingle re-roofs here take two to three working days, and tile relays take about a week. We stage material in the driveway and keep the street clear for neighbors.

Questions from Garden Grove
How do I know if my Garden Grove roof needs replacing?
Look for curling or cracked shingles, granules in the gutters, cracked tiles and stains on the ceiling. If several of these show up across the roof, replacement is usually more sensible than repairs. We inspect your Garden Grove roof and show you photos.
Can you re-roof a Garden Grove apartment building with tenants inside?
Yes. We give notice of work days, keep the roof dried in each night and protect walkways and parking areas. Most low-slope apartment roofs in Garden Grove can be done in phases to limit disruption.
Do Garden Grove roofs often need new decking?
Many older Garden Grove homes have some soft or damaged decking from past leaks. We check during tear-off and replace only what is needed. We tell you the per square foot price for decking up front.
