Roof Installation Modesto, CA

Every home is made of four primary walls, a strong foundation, and a reliable roof. The roof does not only shelter you, but it completes your home, and while living under it, you are trusting it with your lives. Everyone living under the one roof, you, your parents, your kids, and everyone is counting on the top to shelter you and keep you safe.

When it comes to a roof, you cannot compromise on the quality of the material used or anything else. It would be best if you always had everything perfect so your home can be the best and keep you safe, warm, and in good shape. Faulty material or faulty architecture can lead to some severe disasters and put everyone at risk.

Roofing Permit Process modesto, CA

There are two ways to get a roofing permit in the planning department in Modesto, CA. A permit can be pulled as a homeowner or as a contractor. As a homeowner, you certify that you will perform the work yourself. Suppose the homeowner decides to hire someone to help. California law requires that the person providing employment comply with the employment laws. Workmen’s compensation insurance and payroll taxes are the most significant liabilities.
Contractors take all the liability and usually have all the required insurances to comply with the law.
A roofing permit must be issued on a roof when 50% of the roof needs to be replaced.

Gutter Systems modesto, CA

When replacing a roof or repairing a roof, it is the perfect time to update the gutter systems. Gutters are easier to install when the roof is removed, and it is evident where the attachment location will perform best.
Usually, installing a gutter on an existing roof causes roof damages. We have seen gutters installed lower than the channels need to be, causing water to cause dry rot to the fascia boards.

The following stores provide roofing materials. We recommend buying from these suppliers because they offer rooftop delivery.

Loading a roof using a ladder is not just liability, but it is hazardous.

MODESTO Loves Our Roofing Company

No pressure, friendly and they communicate very well. I have two meters and multiple outbuildings. We needed two systems. I had consultations with 5 solar installation companies and simply solar was the most transparent, friendly, and even during the Covid-19 crisis they kept us up to date on the progress of our installation. We are up and running and feeding the grid. I'd highly recommend them for your solar PV system. Give them a call.

Great experience with Grandmark Energy with planning, installation and follow up so far. We've had the system for close to a year now, and it has produced as promised. Worked with Miguel assisted with the municipality rebate. They reviewed past energy usage, discussed plans for potential electric vehicle in the future, and recommended panel coverage to meet our needs. No electric vehicle, yet, but the extra capacity has helped with increased household use during COVID.

I am very glad that I decided to give them the contract to replace the old roof of my house. Not only did they redid the roof, but they also installed the Newly designed Solar Panels with it. It is seamless and looks wonderful, no worries about birds or pests taking residence underneath but also supposed to prevent common problem of water leaks through. My roof looks beautiful, what a transformation from the old one. I have nothing but praises to the wonderful staff that took care of this project. Neydi was so efficient in coordinating the process, she has a wonderful personality, very easy to deal and kept me well informed. Alfredo, the project manager also was so prompt with keeping me informed & answered my questions any time. He made sure I am aware of the progress of the project. The workers were very experienced & did not waste time at all. They were very prompt and workmanship was superb. I am very happy and proud I choose them. Yes California roofs & Solar thank you so much for the job well done!
