"I was originally anticipating to install an asphalt shingle roof But due to the unforeseen condition of the decking I decided to change the scope of work and install a metal roof on my house. The project manager has done a great job communicating throughout this process And I am looking forward to working with him on the metal roof install."

"The Castillo Construction LLC personnel are customer oriented and proposed good cost-benefit solutions. They replace damaged and missing sheathing, they corrected plumbing venting errors (by previous subpar work by a different roofer), and they eliminated unnecessary components from the roof which will reduce the cost of future roof repair work. I will use them again."

Roofing FAQs, answered by experts

Wood shake roofs are durable, energy-efficient, and offer a natural aesthetic. Composite options provide similar looks with less maintenance.

A standard roof can hold a live load of about 20 pounds per square foot. However, gable roofs often have steeper-than-average slopes, so calculating their weight capacity can be challenging. If the slope of your gable roof is greater than 4:12, the live load needs to be decreased to allow for a larger dead load. Ask your roofer exactly how much weight your roof can support.

No, a chimney crown is not the same as a chimney cap. A chimney crown is a flat cement area on top of a masonry chimney. It starts where the masonry part of the chimney ends at the very top and domes upward toward the flue opening. A chimney cap sits on top of the crown over the flue. It is usually made of metal and allows smoke to escape without letting in rainwater.

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.

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.
