Sealing a Roof with a Roof Coating

Sealing a Roof with a Roof Coating

Want to increase the lifetime of your roof? Sure, who doesn’t? But in day-to-day life, your roof surface is exposed to sun and rain, wind and weather, storms and ice—and it’s hard to face up to the weather day in and out without suffering touch, wear, and tear. While a typical roof can sometimes go the maximum amount of 20 years without a full replacement, storms and sun can definitely cause damage, and you recognize what damage leads to leaks.

What Does Sealing a Roof Mean?
Roof sealants are added to your roof to increase its anticipation. Sealing a roof provides an additional layer of protective coating which will help prolong damage from extreme climates and other outdoor elements. Sealants are beneficial for roof types that collect water and debris like flat roofs. It also can be used on other angled roof types as they age to guard against future damage.

Once applied, the sealant takes the brunt from the sun, rain, and ice and not your roof’s shingles. Additionally, roof sealants can make your roof a touch more fire-resistant and stop the expansion of mold and algae.

Sealants and coatings got to be applied by professional roof contractors who have experience applying them. For example, a novice roofer may leave pinhole-sized openings within the coating, which, believe it or not, are often enough to cause leaks and other issues.

How Much Does it Cost to Seal a Roof?
The cost to seal a roof will depend upon your roof’s dimensions, and therefore the sort of roof sealant or coating you use. On average, homeowners can pay around $875 to seal a roof. If you were to seal a roof with the foremost popular silicone sealant, you’d expect to pay $1.00 to $1.65 per sq ft for coating materials and 0.50 cents per roof sq ft labor and installation.

Sealing a Flat Roof
If you’ve got a flat roof on your home, you almost certainly already know a touch bit about waterproofing. Adding sealants on a flat-roofed house is necessary—flat roofs are designed quite like big swimming pools with drainage systems that carry water off the surface and down onto the bottom. For this reason, they have to be entirely sealed—even the tiniest crack can let water into your underlayment and, eventually, spring a leak in your home.

The right quiet sealant depends on what your roof is formed out of. For example, a metal roof coating won’t be right for concrete and the other way around. Although roof coatings are necessary for flat roofs, they’re much less popular for sloped roofs. However, there’s been an enormous development within the types and intended purposes of coatings within the past 25 years. Therefore the roofing industry is beginning to see more pitched roofs get sealed.

Benefits of Roof Coating Sealants
Roof sealants don’t serve only one purpose—there are a couple of advantages you’ll get, depending, of course, on the sealing you choose. Here’s a rundown of these.

Waterproof and Protect Roof Surfaces. We’ve talked tons already about how roof sealants function as a water-proof coating over a variety of various roof surfaces. Elastomeric (i.e., rubber) and silicone roof sealants form a protective seal over your roof—and the simplest kinds are going to be breathable also to permit moisture from household activities—like cooking and showering—to escape through your roof. Many manufacturers claim using their products can extend your roof’s life by several years or more.
UV Protection. Sitting calls at the sun all day long are often tough on your roof—particularly if you’ve got asphalt shingles. Ultraviolet rays cause molecular changes within the shingles, and eventually, that results in curling and degradation. Some roofing materials contain reflective materials to limit this problem, but differently, try to do it with an honest roof sealant. Reflective elastomeric roof coatings can prevent UV damage, consistent with some roofing professionals.
Increased Fire-Resistance. In some cases, roof sealants also can act as fire-retardants for your roof. Of course, if you’re really concerned about your roof’s fire rating, installing a metal roof is perhaps the simplest thanks to going.
Prevent Mold Growth. Rubber roof coatings have a reasonably low permeability, which suggests they don’t stay moist—or allow harmful microorganisms like mold and algae to flourish. That’s a boon if you reside in a damp area where mold threats are high.
Reduce Heat on Your Roof and Reduce Cooling Costs. Here’s where it gets controversial again. There is a variety of building professionals and experts out there (including, at one point, the Department of Energy) who believe that colored roof coatings are an environmental win. Unfortunately, though, there’s been some evidence that these sorts of “cool roofs,” as they’re known, actually increase the warmth island index when reviewed en bloc. So it’s unclear how helpful cool roof paint actually is. Plus, various scam manufacturers have sold roof coatings meant to scale back energy consumption that basically do nothing at all—so it’s going to be best to avoid this type of sealant altogether.

Do Roof Coatings Work?
When you see website domain names like, you recognize that something fishy goes on. Roof sealing sometimes gets a nasty rap because, like many roofing processes, roof sealants popularly get sold that bill themselves for false claims, like improving roofs’ thermal performance. As an example, representatives from a roof coating company within the UK were charged with five years in jail for fraud—courts found that they falsely claimed their sealing products would scale back heat loss by 25 percent. It’s cases like these that have earned roof sealants their detractors, although some products accompany actual benefits. Confirm you understand what roof sealants are good for and, therefore, the actual benefits that your roof coating will provide you.
