An All Seasons Roofing & Waterproofing technician works on a client’s roofing system.

All Seasons Roofing & Waterproofing, Inc. has been serving the Greater Bay Area for more than 25 years and is one of the most well-established roofing contractors in Northern California. The company provides commercial, industrial and residential roofing; reroofing and waterproofing; maintenance; gutter and rain collection system inspections; and emergency repair services.

All Seasons Roofing & Waterproofing is a preferred installer in good standing with several major industry manufacturers. The company is dedicated to setting the standard for quality workmanship and continues to advance with the latest innovations in roofing materials, application techniques, and installation technology. "We apply superior service and artisanship to install dependable roof systems that will provide years of performance," says owner Vlad Gorshteyn.

Mr. Gorshteyn and his team are committed to providing value through extensive technical expertise in roof system design, use of only the highest quality products, and competitive pricing options through cost-effective solutions for every project. All Seasons Roofing & Waterproofing also actively participates in industry organizations that promote professional excellence in roofing practice and business standards.

"We believe in partnerships built on trust, integrity and performance. Our approach is simple: Use the knowledge, skills and professional standards of our team to solve problems in a practical, cost-effective way. Our objective is to serve our clients at the highest level they both expect and deserve."

If you’re thinking about replacing or repairing your roof, don’t forget about supplementary insulation.

A common motivating factor for fixing up an old roof is to improve the insulation of the home, but many homeowners don’t realize that significantly increasing a roof’s insulating properties usually requires additional measures. “A new roof will definitely improve the sealing, and it can even enhance energy efficiency depending on the type of application, but it won’t have a significant effect on insulation by itself,” says Cameron John, residential sales manager at All Seasons Roofing & Waterproofing, Inc. in San Jose. “In order to be an effective insulator, a roof needs supplementation.”

One of the most important of these supplementary elements is attic insulation. Simply furnishing an attic with insulation rated R-30 or higher will do more to keep out both heat and cold than a roof replacement. Many homeowners have never upgraded their attic insulation, so those who replace old insulation with new, improved products often see a significant difference.

Another way to improve your roof’s insulating properties is by installing a radiant barrier, which is placed between the roofing materials and the attic insulation. As heat enters the attic through the hot roof, a radiant barrier reflects it upward before it reaches the attic insulation, which reduces the amount of heat transferred to the rooms below the ceiling.

When looking for a reputable roofing contractor to handle your project, make sure you consider the company’s experience and ability to work with a wide variety of roofing materials and installation methods. There are numerous ways to install a roof, and a good contractor will be able to advise you about the pros and cons of each option. For example, if your roof has a fairly low slope and you want to use composition shingles, your contractor needs to install a special underlayment to prevent leaks. If your contractor fails to mention that before work begins, you’ll end up with a leaky roof.

Maintaining customer satisfaction is a crucial as levels of customer satisfaction is simple: apply its vast amounts of industry experience and knowledge to every job, regardless of its size. "Roofing is a complicated process, so the fact that we know exactly what we're doing is very beneficial to our clients," says Residential Sales Manager Cameron John. "We also understand the importance of staying up-to-date with industry developments, and we utilize those innovations whenever possible."

All Seasons Roofing & Waterproofing has been providing roofing services for commercial, industrial and residential clients throughout the Greater Bay Area for more than 25 years. The company's extensive list of services includes general roof maintenance, re-roofing, gutter and rain collection system inspections, emergency repairs, and more.

Unlike less experienced roofing companies that only have the training or equipment to work on certain types of roofs and are forced to limit their services as a result, All Seasons Roofing & Waterproofing has the in-house capabilities to work on all types of roofing systems, including flat, low-slope and steep. "We can do just about anything our clients need in terms of their roofs," confirms Mr. John. "Our superior service and artisanship allow us to install high-quality roofs that provide years of dependable performance."

Another distinguishing attribute of All Seasons Roofing & Waterproofing is its ability to offer specialized waterproofing services to its clientele, which Mr. John says is an important distinction in the roofing industry. "Not every roofing company is up to speed with the latest waterproofing techniques, so we have a real advantage in that area. We can waterproof everything from roof coatings and vapor barriers to architectural sheet metal and pedestrian deck coatings, and our customers really appreciate that."

I like the professionalism of the staff and the way the guys who were out here doing the dirty work went about their business. They worked hard and they were very professional. The salesperson who came out with the presentation was very knowledgeable and very good at conveying it to us. His presentation was far better than other companies we looked at. Most of the other guys came across like they were reading from a few notes scribbled on the back of a matchbook. I thought the whole experience was great.
