Get matched with top roofers in Colonia, NJ

If you’re looking for a cost-effective alternative to a traditional chimney, consider having a dummy chimney installed. Dummy chimneys can either be aesthetic-only or fully functional and can be installed on both new and older homes. Whether installed to match your neighborhood’s aesthetic or to vent your chimney, dummy chimneys are made out of a Glass-Reinforced Plastic (GRP) core, then covered with brick or stone slips to look like a traditional chimney.

Gable roof construction can last for 100 years or more without needing structural repairs, although the lifespan depends on your climate. Since gable roofs are great at shedding rain and snow, the actual roofing material on top will last for between 20 and 100 years or more, depending on the material you choose. If you’re unsure that your gable roof is up to par, have a roof inspector take a look.

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.

Fall is widely considered the best time of year to replace a roof. The moderate temperatures are ideal for roofing crews to work and for new shingles to seal properly. Additionally, autumn weather is often drier, reducing the risk of weather-related delays compared to the rainier spring season.

While spring is also a viable option, the higher chance of rainfall can slow down the project. The main drawback to a fall installation is that it's the peak season for roofers, which can lead to higher prices and scheduling challenges.

To potentially save money, you could consider scheduling your roof replacement during the summer or winter off-seasons. However, both seasons have significant disadvantages. Extreme summer heat can make shingles too soft to handle, while winter's cold, snow, and ice can create dangerous working conditions and prevent shingles from sealing correctly, as they typically require temperatures above 40-45°F.
