This depends on the design of your roof and any preexisting issues. If you have water and puddles pooling, no matter the roof type, apply a coat of sealant immediately. Beyond that, seal a flat roof every five years, though constant rain and snow hasten this time frame to three or four years. Add a few years for sloped roofs, waiting six to eight years between applications, as water does not pool with these designs.

Fall is generally considered the best time of year for roof repairs. The weather is temperate and typically drier, which makes for safer working conditions and fewer delays. The days are also still long enough to complete the work.

Spring is another good option and is a popular time for repairs to fix damage from winter storms. However, frequent rainfall can slow down progress. Spring may be a less busy season for roofers than fall.

Summer can also work for roof repairs, but extreme heat can make asphalt shingles too soft and difficult to work with.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.

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.
