Redwood City Roofer

Rainbow Roofing has been roofing in the San Francisco Bay area for more than 30 years. Joe DeLago, the owner of the company, has extensive knowledge in not only re-roofing but the components of the roof structure.

We have been voted BEST OF REDWOOD CITY 2012!!

There are times on a re-roof that it calls for an experienced carpenter to repair damaged areas of roof structure before moving onto the installation stage of the roofing process, Joe was a carpenter before becoming a roofing contractor and is well versed in all types of structural and framing repairs if needed. This sometimes saves the homeowner from having to call in a carpenter or specialist for certain repairs.

Joe screens his employees and trains them in the knowledge that he himself has gained with over 30 years as a contractor. Joe states that "By keeping a crew small, we can keep quality at the highest level and not have to worry about roofs being installed improperly. It also makes for happier employees".

Over the years RAINBOW ROOFING has installed roofs just about all over the SAN FRANCISCO BAY AREA and has re-roofed anything from backyard sheds to multi-million dollar homes.

Rainbow Roofing is a quality installer of SUN TUNNELS. At a fraction of the cost of installing a framed skylight, you can install a SUN TUNNEL to add much needed light to that dark room or hallway.

We also install a quality gutter guard that are very strong and do not fold, bend or come off in high winds. These are great for keeping leaves and debris out of gutter and downspouts and keeping gutters from clogging.

How to Find a Qualified Redwood City Roofer

The roof over your head is literally your first defense against the outside elements. If your roof is in poor condition you risk serious damage to your whole house and all your belongings. Moisture can enter, causing further damage to the roof, ceiling and interior walls. Continually neglecting your roof will only make for costly repairs down the road. The sooner you call a competent Redwood City Roofer to take care of the problem, the more money you will actually save.

No matter what type of roof you have, replacing it can be a major expense. The roofing materials are only a small part of what you’ll pay. The biggest expense in hiring a qualified Redwood City Roofer will be in labor. Roofing is a trade that requires skill and knowledge in a number of other disciplines including math, general carpentry, and framing construction. Finding a Roofer is the easy part. Finding a qualified Redwood City Roofer that has the experience and know-how to do the job right and leave you with a secure roof over your head might take some time.

Getting Your Bid from a Redwood City Roofer

Once you have a few companies in mind, it’s time to ask for some bids. Ask for a bid from each Roofer you feel comfortable with. Some people say the more bids the better but this is not necessarily true. If a Roofer feels there is too much competition he may simply walk away. In actuality, a well known Roofer could have other clients waiting while you're still in the decision process, thus you may lose a bid from the most qualified Redwood City Roofer. So keep the bidding to a select few.

Remember when asking for a bid, you don’t want just a slip of paper with a number on it. You need to see a detailed estimate of what the job will entail and all costs for materials and labor. Provide each Redwood City Roofer with a detailed list of what you’d like included in the bids and this will help ensure that you receive some uniform quotes that are easy to compare. If you find that one bid is considerably lower than the rest, it will also be easier to pick out the differences.

You don’t necessarily want the lowest bid, but the highest one isn’t a guarantee of better service or materials either. You want a good combination of price and service. If one bid seems considerably lower than the others ask the Roofer why. One Roofer may simply have lower overhead, fewer workers or a better source for materials and this savings can often be passed on to the customer but make certain the Roofer can back up any claims he makes.

Once you’ve found the Redwood City Roofer you feel is right for the job, you’ll need to work up a contract.

GREAT JOB! We have used Joe on two different homes and we love his work".
Stephanie - Redwood City, CA
Did my roof with Joe. EXCELLENT SERVICE. He did the roof and solved all the problems that one can encounter in the process without worries and without charging me extra for anything. In some aspects he left things better than he found them. He improved on my skylight installation and flashed and weather-stripped it better than original installer. He installed and painted a gutter on front of home without me asking at no added cost.
