Asphalt shingles blister when air gets trapped between building materials, either within the layers of the shingle itself or in adhesives on the undersides of the shingles. As the roof heats up in direct sunlight, the trapped gas expands and creates a bubble in the roof. Eventually, the bubble can pop, leaving an exposed area of decking and underlayment.

A spray foam roof costs an average of $6,000 to install, making it one of the most affordable flat roofing options available. Costs can increase if you have a complex roof design with many roof vents or have a roof that’s larger than average. While up-front costs are relatively low, keep in mind that ongoing maintenance and repairs tend to be more expensive than you’d see with other flat roof materials.

Roofers don’t typically replace vent pipes themselves, but they do handle the flashing and seals around vent pipes when working on a roof. During a roof replacement or repair, roofers inspect the vent pipe flashing for damage, replace deteriorated seals, and ensure the pipe is properly integrated into the roofing system to prevent leaks. If the vent pipe itself is cracked or damaged, a plumber is usually required to replace it, while the roofer ensures the roofing components around the pipe remain watertight.

Installing a green roof costs between $10 and $30 per square foot. Green roofs cost slightly more than standard roofs, due to the extra materials and installation know-how required. The type of green roof you choose also impacts the cost, with intensive roofing systems costing considerably more than extensive roofs.
