Roofing questions, answered by experts

Unfortunately, there’s no definitive answer to this question, but the wind rating of your shingles will give you a good idea of what wind speeds can damage your roof. If you’re concerned about damage, inspect your roof following windy conditions to look for signs of wind damage to your shingles. When in doubt, consider hiring a professional who fixes roofs to carry out an expert inspection. Remember that hurricanes, tropical storms, and tornadoes are likely to cause the most damage, but even severe thunderstorms can bring winds that compromise your roofing system.

Rain shouldn’t come in through your ridge vents unless your vents are damaged or the rain is accompanied by very high winds. Most ridge vents use flashing or baffling to keep out rain, snow, and debris. If your ridge vent isn’t baffled, rain is more likely to enter your attic, so ridge vents with baffles are a better choice in areas with regular rainfall.

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.

You can technically put new roof sheathing over old, but it isn’t recommended. Firstly, it isn’t hard to remove sheathing. Secondly, when you install new over old, you trap whatever moisture is in the older layer. This can cause problems later on, especially if you have a humid house. Another reason not to add new over old is the weight factor. Finally, when you cover an old layer, you lose the ability to inspect it for damage, rot, or mold.

Roofing felt is the most common type of roof underlayment, likely because it has been around the longest. It’s called roofing felt because it is often made of felt soaked in asphalt. Depending on the type of roofing a home has, roofing felt comes in different thicknesses. 

If properly installed and maintained, roofing felt should last between 10 and 25 years.
