Best roofers near Irvington, NJ

You can walk on a TPO roof, but you should only do so when necessary and wear footwear that’s less likely to puncture the surface. If you anticipate needing to frequently walk on your TPO roof, reinforce walkways to protect against punctures. TPO roofing can also be slippery, so in most cases, you’ll want to leave walking on it to the pros.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

The least suitable roof for solar panels is a wood shake roof. An electrical mishap with your solar panels could start a fire on the roof, so some areas don’t allow solar panels on wood roofs. You don’t have to let a wood roof stop you from going solar. You can replace your wood shakes with shingles. Installing the panels on the ground is another option.

A roof replacement can take anywhere from one to 14 days. For most homes, a full replacement that includes tearing off old materials takes about one to two days, though the average project can last up to 12 days. The exact timeline depends on several factors, including the roof's size and complexity, the type of roofing material, the crew size, and weather conditions. Certain materials take longer to install; for example, metal roofs can take seven to 14 days because the material is more difficult to work with than asphalt shingles, wood, or tile. A re-roofing project, where new shingles are installed over old ones, can take half the time or less. It's also important to factor in the time needed to obtain necessary permits. A professional roofing contractor will typically complete the job faster than a DIY approach.
