While cutting corners can save time on a roofing job, it can be costly when contractors deviate from the norm when installing a roof. Even a minor oversight can cause a leak and, if the customer has problems later on, the roofer could be held responsible. Installation techniques vary depending on materials and building type. Customers can look at more info on the guidelines a Roofer in Des Moines should follow.
Follow Slope Guidelines
A roofer should pay attention to the roof’s slope, especially where the grade changes. Valleys are particularly vulnerable to leakage, and some materials won’t adhere in these areas. To avoid issues, roofers should familiarize themselves with roof slope before choosing materials.
Install Materials Properly
According to the experts, issues with flashing can lead to severe water damage. There are two common mistakes made with flashing, which is a key component of the roof’s weatherproofing and strength.
Poor installation: Flashing must be installed with the U shape in the direction of the valley, and it should be under the shingles, not on top.
Not using enough securing material: If the roofer does not use enough fasteners or caulking when securing the roofing material, it can cause valley flashing to warp and, eventually, leak.
Prevent Climate-Related Issues
Every area has weather issues, especially in colder climates where roofs may buckle under the weight of snow and ice. A common issue occurs when snowmelt refreezes at an overhang, trapping water under the shingles and causing leaks. To avoid ice dams, the roofer should install an underlayment to keep water from penetrating the underlying spaces.
Avoid Warranty Problems
Roofers shouldn’t be held liable when materials fail, but they do have to deal with manufacturer warranties.
Prove the leak wasn’t the customer’s fault. Installation instructions that require extremely accurate nailing might not be very realistic. A good roofer will work around this by choosing products that have a lower margin of error.
Build a relationship with materials manufacturers. Some roofers change materials suppliers just to save money, but building relationships with vendors can protect the business in the long term.
The homeowner has a significant part in ensuring that the roof stays in good shape. The roof should be inspected twice per year by a Roofer in Des Moines, as leaks can cause severe issues when left untreated. The sooner problems are caught, the less likely the customer will be to question the roofer’s workmanship.
