"Found Sentri on Angi. Jeanette and Violet were very pleasant and efficient in getting a contractor to me in the time frame needed. The contractor was excellent and the roof looks great! I would definitely work with them again if I had additional projects."

Hello my names Christopher i am 23 tired of working for a boss that doesnt understand what goes into things when we install. I have finally turned over a new leaf and wanted to start dping things on my own. I have worked for a few different landscaping companys, i have done some demo work for family and friends, i also worked at thrasher for ahile working my way up to team lead. I just had a baby last year on December and i want to be able to see her grow! Thats why im here to get jobs that i want. I dont wanna work for a boss who has no idea how the stuff i install goes in. I want to be thats hands on boss that is for the customer. Tired of meeting quotas. I want to love what i do for work and believe you me i love getting dirty and getting the job done.

Roofing questions, answered by experts

A solar roof can replace an existing roof. Solar panels fit on top of traditional roofs. In contrast, solar roofs that contain photovoltaic (PV) materials, like solar shingles and solar tiles, are standalone roofing systems installed as a main roof. In some cases, installers can place them on existing roofs and as part of new construction. Carefully assess and choose the right type of solar roof replacement for your home and needs.

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.

Yes, you can walk on torch down roofing. It is durable and tear-resistant enough to handle that kind of low-level wear. Remember that torch down roofing can get uncomfortably hot in certain climates. Dark roofing absorbs heat and can burn bare feet. If you want to use a roof deck for lounging, you may want to install a lighter-colored PVC membrane.

Roofers can install roof vents. Updating, upgrading, or simply replacing your roof's existing vents is common when installing a new roof. If you're looking to upgrade your ventilation system with a powered version, a local HVAC professional can also help with the task. If adding roof vents to your home is necessary while installing an addition or during other renovation work, your contractor will handle or hire out the venting work.

Flat roofs are a solid option for people who want extra outdoor space. Flat roofs are very common in other parts of the world and only recently has the U.S. started to see the benefit in the increased space. Flat roofs are also easier to maintain and pose much less of a safety risk, which allows for more DIY work for handy homeowners. Some people also build green or living roofs that grow plant life.
