Pros and Cons of Different Roof Coatings

35067309_sIf you own a commercial building, you may want to consider roof coating for the roof. This is because when you coat your roof, it acts like another barrier to protect the roof from the sun’s rays. It does this by increasing the UV protection which also helps to reduce the energy cost of the building. Another thing that roof coatings do on commercial property is to help prevent the ponding of water with varying degrees of effectiveness depending upon the product. So below are the strengths and weaknesses of different coating materials so that you can make an intelligent choice when you do this job.

  • Acrylic roof coatings are good for most climates and are cost effective. It’s water based and is reflective; easy to use and UV resistant. However; acrylics need to be applied when the temperature is 50 degrees or above. Plus; acrylics will also lose mil thickness with the weathering; and in situations where ponding is normal after every rain, it doesn’t do well.
  • Polyurethane roof coating handles traffic and is more resistant to impact than the other coatings. Also, aromatic and aliphatic are the two main types of polyurethane coatings. For a base coat, aromatic coating is usually used because it’s not UV stable. Aliphatic coatings are more UV stable, are cleaner and hold color well, but are also more expensive.
  • Silicone roof coatings won’t get brittle or hard. Furthermore, it’s good in water ponding situations and is erosion resistant. With silicone being moisture cured, the weather being humid even helps with the curing. The down side is that silicone will hold dirt, but when it rains, the rain acts as a cleaner. But because of this; over time, the material will lose its reflectivity. Plus; silicone is difficult to adhere to so when the roof needs redone, you either have to either remove the silicone or use something that’s compatible with it.

Having a coating put on your roof is an excellent solution if feasible, instead of just having a shingled roof. But get the advice of a trusted professional for the right and needed roof application.

Repairing Water Damage on a Multi-Family Dwelling

56577481_sWhen repairing the water damage of a multi-family dwelling, there are some things to consider. First of all, is it a hole or weak spot in the roof that needs patched or does the whole roof need to be redone? Or do you need to replace a collapsed ceiling inside the multi-family building or just repair it where it leaked? Is the building structurally safe or did the damage compromise the integrity of the building? Is the damage from a rain storm; or a more severe storm or flood? Also, do you need to call a professional contractor to access and repair the damage?

So below are the signs of structural damage where you will need professional help:

  • If the building has shifted its position on the foundation; or if there are stairs have shifted and walls now slant and there are broken pilings.
  • If the floors aren’t level or if a crawlspace or the walls of the foundation have caved in or cracked.
  • If the foundation has been undermined by erosion that’s cut into the soil at the bottom of the foundation.

Now if the building has been damaged you need to have these steps taken:

  • Remove the damaged materials and permit the building to dry out. To prevent additional water damage, protect with tarps and other barriers that will contain the water where you need to. Some materials which have been water damaged can be salvaged, but some can’t. Also by reusing materials that haven’t dried thoroughly in repairs, they can buckle or cause mildew problems.
  • You can keep drywall that has only been dampened by rainwater that’s clean. The drywall can’t be sagging, can’t be mildewed and it can’t have lost its smooth texture. However; wet insulation has to be removed immediately from the ceiling, and walls need to dry completely before you can repair them if you are not tearing them out.
  • If any materials can be salvaged, move them to a place that’s dry and secure. Also, you can remove the materials which aren’t salvageable to another area, but make sure you save them until the insurance adjuster sees them.

If handled correctly, damages can be repaired smoothly, but seek professional help for the things you cannot do correctly and to code.
