Your mobile home may develop leaks over time. Mainly, these leaks stem from eroding caulk around air conditioning units or vents on the roof. Seals in the roofing and even screw holes can become problematic. When you find a leak, you’ll need to apply some roof sealant in order to keep your home dry. The type of sealant you use very much depends upon what type of roofing you have. Most mobile homes will need to seal metal roofs, but some have plastic. Choose your materials to match your needs. Once you seal your roof properly using a roof sealant you should be able to maintain your roof for many years without risk of additional leakage.

Step 1 - Prepare the Roof

Before you can begin to add sealant to your roof, you will need to clean it and fix any problems which might already be on the roof. Use a brush or broom to wipe away small objects like twigs and dirt that have fallen onto your roof, and then inspect it for holes or cracks which might prevent the roof sealant from adhering properly. You should avoid walking on the roof while the adhesive is being applied, as this could cause more damage to the roof. Instead, use a ladder to access the parts of the roof as you work.

Step 2 - Fix the Roof

Before you can proceed to the sealant, you will need to repair holes in the roof. The best way to do this is to use a waterproof external caulk, which can be bought from local home improvement and hardware stores. You should also try to ensure that the roof is screwed down properly. Tighten any loose screws using your screwdriver, or hammer them down if they are loose nails. Leave the roof to dry completely before you add the sealant.

Step 3 - Add the Sealant

Now you can apply the sealant to the roof. You will need to use a primer to prepare the roof, and then leave that to dry. Then apply the sealant using a paintbrush. The sealant should not be applied too thickly, as this can prevent it from drying, and may cause it to leak down the roof, and either into the home or onto windows and door frames. Go carefully over any screw holes, nail heads, or other parts where the metal might be at its weakest.

Step 4 - Finish

Once you have added the first layer of sealant, leave this to dry thoroughly before applying the second layer. Make sure that there are no leaves or dirt on the roof before the second layer is applied. You may prefer to use a paint roller rather than a brush, as you need to avoid treading on the roof and a roller allows for an extension. Leave your sealant to dry completely, and then hose down the roof with the garden hose. Check for signs of leaks in the rooms beneath, and if there are none, you can then add any paintwork you desire.
