"Custom Roofers III, had the lowest bid for our flat roof. We didn't realize they weren't going to take off old roof. Put new materials right over old roof. Not a fan of that decision."

"While removing the old roof, the aluminum coverings on our mansard roof dormers were damaged. The roofing crew attempted to repair the damage but the result was not satisfactory. As compensation they deducted a small amount from the total bill."

Roofing questions, answered by experts

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

This will depend on your existing roof to some degree, but it’s common to raise a roof 4 to 8 feet. The exact amount you can raise is subject to the existing structure. For most homes with average roof slopes—20 to 45 degrees—you can raise the roof around 5 feet.

Heated roofs are a preventative measure and don’t have an outsized effect on your home’s value, so there is no definitive answer to this question. If you diligently monitor your roof in colder months, ensuring there is never snow or ice buildup then no, maybe they aren’t worth it. However, who really watches their roof every day or goes out in freezing weather to rake the roof? For most people worried about roof damage in the winter, heated roofs are a good investment. 

Tile roofing is durable, fire-resistant, and energy-efficient. It also adds aesthetic appeal and, with proper maintenance, can last 50-100 years.

Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.
