Roof Installation

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.

Re-Roofing

When repairs aren’t sufficient to fix your previous roofing system, it is time to get your home re-roofed. This ensures that your home is protected and proficient at guarding you against climatic adversities while making your home look beautiful.
Why Choose Grandmark as your Roofers in the Bay
Grandmark has been in the roofing business since 1996. That is beyond three decades of extensive experience, which you can harness to get your roof solutions designed according to your exact needs. Our experience has made us the ultimate pros in choosing the right materials, styles and providing superior craftsmanship to build your roofs that withstand climatic adversities with great endurance.

Roof Inspection

To determine if a roof is in good shape, Grandmark recommends an in-depth roof inspection.
The inspection can show the roofing membrane’s current estate and how to ensure the roof will perform correctly and for how long.
Our roof inspection reports come with video. There is no better way to help our customers understand what is going on with their roof and how to fix it when needed.
Grandmark Energy provides pricing to correct the problems within 24 hrs in most cases.

Roofing Permit Process

There are two ways to get a roofing permit in the planning department of the city where the permit is being pulled. 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

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.

Roofing Suppliers in the Bay

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, it is hazardous. Often these roofing suppliers will cost as much as stores without rooftop delivery.

  • ABC Supply
  • Allied Building Products
  • R & S Supply

General Roofing Codes

  • Here are some of the essential items to comply with when installing a new roof. 

    • All projects above $500 and up will require a permit to be issued.
    • The project must comply with the energy code requirements of title 24
    • Roofs with slopes of 2/12 will need a double layer of roofing underlayments.
    • Roofers below 2/12 pitch require roll roofing systems.
    • Provide proper attic ventilation
    • Ensure appropriate clearance on items conducting heat
    • Ensure the roof is dry rot free. and nailed up to code
    • Make sure additional structures are permitted.
