"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

A square of shingles covers 100 square feet and usually ranges from 150 to 240 pounds. It all depends on the material and type of shingle.

Cool roofs last for roughly 15 to 30 years. You can install a cool roof coating over an existing roof, but keep in mind that this might not be worth it if your roof is near the end of its life expectancy. If your roof isn’t near the end of its life, adding a cool roof coating can make your existing roof more energy-efficient and help it last longer, so you’ll have to weigh the pros and cons.

To cap off a chimney flue, start by measuring its width, length, and diameter, if it’s circular. Purchase a cap that fits the flue, and decide whether you want a temporary or permanent model. Then, slide or insert the cap onto the flue and secure it with a screwdriver. Be sure to avoid over-tightening the screws to prevent chimney damage. 

The most crucial roof-strengthening method is achievable by following proper construction methods and guidelines from the start. To strengthen an existing roof, framers and DIYers can add hurricane ties or straps to the structure, sister rafters and other framing or truss members, or install additional fasteners or adhesives where necessary.

Ensures precision fitting, optimizing durability and efficiency against weather elements.
