Roofs Shouldn’t Look Like This!

Anyone who has lived in a home with a shingled roof knows that at some point in time, the roof will have to be replaced. Whether the home is a manufactured (mobile) home or a permanent structure, all of the elements play a significant role in the wear and tear of the shingles.  When it’s time to select a roofing contractor, be careful! Make sure that you’re dealing with a reputable company.  Ask for references if necessary and check them out.  Don’t ever give anyone any money up front because in all likelihood, you’ll never see them again.  The photos shown below are just two examples of what a newly installed roof should never look like.  The first photo shows how wavy a roof can appear if there is a problem with the roof decking.  The decking must be repaired or replaced BEFORE the felt and shingles are nailed down.  The second photo shows caulking that was applied to valleys alongside a gable because someone recognized a problem, usually water leakage.  Using caulking on a newly installed roof is never acceptable.  If the roofers didn’t install the valley shingles correctly the first time, the roofer should have to redo the work again.  However, getting the roofing contractor to tear off the shingles and then reinstall new ones might be easier said than done.  It is possible that a roofer would rather apply a caulking or some type of mastic beneath the shingle rather than re-shingle the area.  If this seems like an acceptable solution, again, be careful.  If a leak occurs in the future, getting the roofer to fix it under warranty will be next to impossible.  One way to test a new roof is to spray water on the roof with a garden hose then check the attic for signs of water leakage.  Don’t wait until it rains.  The sooner a leak is detected, the easier it will be to hold the roofer responsible if an adversarial situation arises.
