"Ervis and his crew did an outstanding job. The price was fair and the quality was excellent. My roof was replaced in one day! I had 4 contractors that gave me estimates for the roof replacement and Jersey Roofing offered the most competitive price. There was a supervisor at all times onsite which I liked. I highly recommend Jersey Roofing for A+++ quality and service."

"Roof was 25 years old and was due for replacement. I also had old LP fiberboard siding that needed replacing in some sections mainly the chimneys. The rest was ok and I couldn't see spending the money to replace it all. George Keller did a terrific job on the roof and worked with me to match the LP siding using James Hardie siding. Carl the estimator took his time gave me a detailed estimate with pictures showing all the sections of siding that would be replaced. George Keller had done other houses in our neighborhood and one neighbor, an architect, used them, so that speaks to their reputation. I would highly recommend them. They are very efficient and neat and will finish your job in a day or two."

Roofing FAQs, answered by experts

Depending on the type of damage your roof shingles have, you may be able to simply repair them without having to replace them. However, if there are more than a few to repair, replacement is likely the easier option. You may only need to replace a few of them. Repair shingles by applying roofing sealant directly under the shingle's damage and then directly over it. 

The four types of roof sheathing are plywood, oriented strand board (OSB), planks, and tone-and-groove boards. The overwhelming majority of homes use the first two (especially OSB) and the other two are not often seen outside of special use cases. Methods of sheathing include solid sheathing, open sheathing where there are gaps, and plank sheathing. Most roofs are solid sheathing.

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.

Many insurance policies will not cover a roof with two layers of shingles. An additional layer of shingles increases the risk of various kinds of damage, and insurers typically won’t pay claims on a roof with an overlay. Adding a layer of shingles may even jeopardize your insurance coverage entirely, so check your policy to ensure you stay within coverage guidelines. 

While spotting a bit of algae on your roof may not bother you at first glance, it is certainly bothering your roof shingles. The presence of algae can cause decay and shorten the lifespan of your roof’s shingles, which can lead to much bigger problems down the road. While this issue may seem cosmetic at first glance, it goes much deeper than that.
