Hardie shingle siding installed, with new aluminum soffit/facia. After siding removal we agreed the roof was toast, and they threw a new one on quickly. The house looks great, and owner Gordo is quick to return calls and get any issues resolved promptly.

Roofing questions, answered by experts

If you're looking for a dependable and affordable option for garage roofing, asphalt shingles offer a durable way to blend a detached garage in with the surrounding residential aesthetic. If you're looking for a more durable and protective option because you're storing expensive equipment in your garage, consider metal roofs that perform well against snow, ice, hail, and heavy rains.

If you’re choosing between a roof overlay and a tear-off, opt for a tear-off and full roof replacement instead of a roof overlay if possible. The cost savings from an overlay can easily be eclipsed by repair costs, the effects of structural damage from the additional weight, and needing to replace your roof sooner than expected. A full replacement will last longer and is less likely to need damage repaired over time.

You can put a green roof on a regular house with a compatible slope. Green roofs are best suited for flat or gently sloped roofs, as steeply pitched roofs can make the installation and maintenance of the green roof challenging. Flat roofs can support the weight of the soil and plants and ensure effective drainage.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes—one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.
