"I had Boss Roofing go to my rental properties outside of Ft Myers to check the tile roofing to see if it might have been damaged from Hurricane Irma. They were quick to check out, access and repair. I would highly recommend them for repairs or replacement."

Roofing questions, answered by experts

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Skipping the installation of a drip edge or gutter apron can lead to significant water damage. Without this component, water is more likely to seep under roofing materials or leak behind gutters, damaging the fascia, soffits, siding, and even the interior of your home, such as the attic. Over time, this moisture can cause rot, mold, and deterioration. In colder climates, a missing drip edge also increases the risk of ice dams, which can lead to expensive repairs. A drip edge is an essential part of a roof's drainage system, and some local building codes may even require its installation to protect the home from water damage.

While you don’t have to let roofers inside your home, it is proper etiquette to offer the use of your restrooms. And if it’s a hot day, it’s polite to invite the roofers into your house to cool off and have a chilled drink.

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.
