How to get the full life out of a roof, what to check each season, and which small repairs are worth doing before they turn into a replacement.
We measured a black roof at 179 degrees on an August afternoon, and that kind of heat load ages an Oklahoma roof faster than the calendar suggests. These answers cover drainage and gutters, sealant and flashing, attic ventilation, tree and debris damage, and how to tell a roof with years left from one that is at the end of its service life.
Two pieces of metal doing two jobs where a roof meets a wall. Step flashing goes in course by course, counter flashing covers its top edge.
The code defines all three. Repair is maintenance, recover goes over the existing covering, replacement removes it to the deck.
Close, rarely exact, and harder every year. Bundles on one job must share a colour code, and yours was used up when the roof went on.
Longer than asphalt, and it depends which metal roof. Standing seam and exposed-fastener panels are two products with two very different answers.
Because the panels are rarely the problem. On an exposed-fastener roof the water usually comes through the screws, where the rubber washer has failed.
Repair when the damage is local and the shingle still matches. Replace when it is systemic. What decides it is usually whether the shingle is still made.
Most standard homes take one day, complex and larger homes two to four. The project around the install is longer and mostly spent waiting.
One square foot of vent area per 150 of attic, halved only under conditions, and one of those conditions is not available in Oklahoma. The arithmetic.
Because kitchen grease reaches the membrane. Every manufacturer excludes grease damage from warranty on every single ply, so containment matters most.
Often it is not. Walls, parapets, mortar joints, rooftop units and condensation all present as roof leaks, and water travels before it shows up inside.
Clear the driveway, take things off the walls, and mow short so the nail magnets work. The checklist we send before every job, and the reason for each item.
A manufacturer can issue a discontinued product letter confirming no match exists, and that letter is a documented basis for replacement rather than repair.
