What are the signs that I need to apply roof sealers?
Common signs that indicate it’s time to apply roof sealer include:
Visible cracks or damage. You may notice small cracks, blisters, or peeling on the roof's surface, which can allow moisture to seep in.
Leaks or water stains. If you're seeing water spots on your ceiling or walls, it’s a clear sign your roof’s protective barrier is failing.
Fading color. A roof that looks dull or faded has likely suffered from sun damage, and a sealer can help restore its protective qualities.
Granule loss in gutters. For asphalt shingle roofs, finding a lot of tiny granules in your gutters means the shingles are wearing down and becoming less effective.
Increasing energy bills. A compromised roof can lose its reflective properties, making your home harder to cool and leading to higher energy costs.
What is the process for applying roof sealers?
During your pro’s visit, you may expect them to first inspect and thoroughly clean the roof, as the sealer needs a clean, dry surface to adhere correctly. Next, they may make any necessary minor repairs before applying one or two even coats of the sealant with a roller or sprayer. They’ll likely work in sections to ensure complete coverage. Finally, they’ll let you know how long the product needs to dry and cure before it’s fully protective.
How do I hire a roof sealing professional?
Taking these steps can help you find the right professional to apply roof sealer:
Get several estimates: A proper estimate should break down the costs for materials, labor, and any prep work like cleaning. It should also specify the type of sealant being used and provide a project timeline.
Read their reviews: Good signs in reviews include mentions of professionalism, a clean worksite, and a durable, leak-free finish. Be wary of complaints about peeling, bubbling, or new leaks appearing after the job.
Look at their portfolios: Check their past work for photos of completed roof sealing projects. The application should look even and consistent. It’s a plus if they have experience with roofs similar to yours.
Find out if they have warranties: Professionals may offer a workmanship warranty covering the application itself. The sealant product should also come with a separate manufacturer's warranty.
Ask important questions: Before you hire, ask things like, “What type of sealant do you recommend for my roof material and why?” and, “What preparation work is included in your estimate?”
How often should you apply roof sealers?
It’s good practice to reapply roof sealer at least every five years. This helps replenish the protective barrier that wears down from sun and weather exposure. Regular sealing can prevent water damage and may help you avoid more costly repairs in the future. A pro can tell you when your roof needs resealing based on climate and local conditions.
How long does it take to apply roof sealer?
It usually takes a day or two for a professional to complete a roof sealing project. This timeline will depend on:
Roof size: Larger or more complex roofs naturally require more time to clean, prep, and coat.
Roof condition: The pro may need extra time to make repairs or thoroughly clean the surface before applying the sealant.
Weather conditions: Sealants need dry, calm weather to apply and cure correctly, so rain or high winds can cause delays.
Type of sealant: Different products have unique application requirements, and some may need multiple coats with drying time in between.
Roof accessibility: Steep pitches or hard-to-reach areas can make the work more complex and time-consuming.
Remember: The timeline for your project will vary depending on many factors. Always ask your pro to provide an estimate.
What factors can impact the cost of sealing a roof?
There are several factors that might impact the cost of this project, including:
Roof size and accessibility: Larger or steeper roofs naturally require more material and labor. If your roof is hard to access or has a lot of features like chimneys and skylights, that can also add to the cost.
Sealant type: There are several kinds of roof sealers, such as acrylic and silicone, and their prices vary. The best one for your home depends on your roofing material and local climate.
Roof condition: The sealer needs a clean, sound surface to adhere to. If your roof needs extensive cleaning or repairs first, this will be factored into the final price. A professional roof inspection can uncover any hidden issues beforehand.
Labor costs: Labor rates can change depending on where you live and the experience of the pro you hire.
Number of coats: For the best protection, some roofs may need more than one coat of sealant, which impacts both material and labor costs.
