Tom and Adam and the team not only gave me peace of mind moving forward with drainage, put in gutters, and re-did the entire exterior of my home (stained wood and stucco), but made it beyond beautiful!! They were communicative, timely, so easy to work with, and the end product is gorgeous. I would recommend them to anyone who needs a construction project done and can't wait to use them again on my next project!!"

Our company history provides you with four generations of construction experience. It began in the early 1950’s when Guy La Rocque’s grandfather ran a successful steel and concrete company and, up until his un-timely death, Guy’s father owned and operated one of Southern California’s largest fence companies. Guy La Rocque acquired 100% ownership of La Rocque Bros Co. in 1979 and in 1981, changed the name to La Rocque Roofing. In 1984 the family decided to incorporate the company, hence the name change to La Rocque Better Roofs, Inc. Currently the company employs two generations of the La Rocque family with no intentions of stopping there. The reputation that we have built over the years is something we understand. It takes a great deal of effort and a daily dedication to our employees, clients, distributors, and manufacturers. We are constantly upgrading our company and looking toward the future. One of Guy’s philosophies is the only thing constant with our company is change.

"Green Planet Remodeling just completed our kitchen remodel and we couldn’t be happier with the results. They were upfront about costs, stuck to the schedule, and the quality of their work was excellent. The design process was collaborative — they really took the time to understand how we use our kitchen and gave us suggestions that made a big difference (hello, hidden spice rack!). They handled everything with professionalism and made what I thought would be a chaotic process feel pretty stress-free. No hidden fees, no runarounds, just good people doing great work!"

Structural Engineering questions, answered by experts

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
