How to Seal the Edge of a Roof

An unsealed roof can allow your home to be damaged. Water can easily break through the barrier of the roof when it is unprotected and cost you money in the long run. Once you have identified a loose shingle on the edge of your roof, it is best to attend to it immediately in order to mitigate any potential damage. Fortunately, for those inexperienced with roof repairs, sealing the edge can even take as little as 30 minutes.
