"I recently hired Devin to reside my house and replace the front door, and I couldn’t be happier with the results. From start to finish, Devin was professional, reliable, and easy to work with. He clearly takes pride in his work—the attention to detail was evident in every aspect of the project. When replacing the front door, Devin discovered rot beneath the old frame. He took the time to properly address and repair all the issues around the door before installing the new one, and did an excellent job making sure everything was solid and well-sealed. The final result looks great and feels very secure. The new siding also came out fantastic and really improved the look of my home. Devin was flexible throughout the project and accommodating with any changes, making the entire process smooth and stress-free. If you’re looking for a contractor who does quality work and genuinely cares about the finished product, I highly recommend Devin."

Roofing questions, answered by experts

Wooden roofs require regular maintenance, are prone to rot and mold, and are frequently the target of insect infestations. Natural wood is also excellent at absorbing and storing moisture—not a positive. In climates where the weather shifts dramatically, the wood can also crack, split, or warp.

Asphalt shingles, wooden shakes, and slate or clay roofing tiles are often replaceable without having to replace the entire roof. It's possible to replace just a few shingles or tiles without much trouble in the case of wind damage or other minor problems. DIYers can perform the task in some situations. However, professional repair is always the best bet when it comes to roofing.

Roofing estimates vary for many reasons, but the most significant ones include differences in the cost of labor based on the contractor’s experience and overhead costs, as well as the quality of the materials your roofer will use for the job. You should get your estimates itemized and make sure your contractors include details about the materials they plan on using. Doing so allows you to compare not only based on the cost but also the value that you’ll get for your money.

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.

No, gable vents are necessary in cold weather. Hot air rises, and heating your home around the clock during winter months creates condensation in the attic. Mold thrives on this moisture, and shutting the gable vent can cause a massive mold and mildew outbreak. The vent needs to stay open so it dries the attic out and doesn't give mold a chance to grow.
