Have you noticed a little bit of sag in your roof?
Although it doesn’t necessarily mean your roof is about to collapse, it may lead to further damage. Besides, a sagging roof is an eyesore that you should be repaired if you want to improve your home’s curb appeal.
However, it’ll be better if you understood what causes roof sagging in the first place. This will give you ideas for possible solutions to solve the problem.
So, here’s a list of roof sagging causes, and what you can do about them:
1. Water Damage
A damaged gutter system and shingles cause rainwater and snowmelt to seep into the underlying wood structure. Over time, the moisture causes the growth of mold, further weakening your roof causing it to sag.
It gets worse when there’s poor roof ventilation that causes water to permeate further.
One of the best ways to minimize water damage is to do regular checkups on the roof. Look for any damaged shingles or flashing system and have it repaired by a professional roof contractor.
2. Too Much Weight
Your roof is designed to support a certain maximum weight load. Any other weight above the limit causes the roof to sag. Too much weight on the roof can be due to long periods of snow, ice, and debris, during the winter.
It’s possible to remove the excess winter precipitation but you have to be careful not to damage the roof and most importantly, watch out for injuries. Inadequate internal bracing, undersized rafters, and other structural issues can also cause failure in supporting the weight of a roof.
It’s best that you leave these repairs to roof contractors. They’re complicated and deserve special skills and equipment.
Pests are every homeowner’s nightmare due to their destructive nature. Unfortunately, these tormenting creatures won’t spare your wooden roof deck.
Once termites attack your roof’s deck, the damage will be evident from a sagging roof.
To reduce the risk of attack by pests, it’s advised that you paint and treat any exposed wooden structure of your roof. Accumulation of debris in the gutter system can also harbor termite larvae. So, be sure to clean your gutters and inspect routinely.
4. Roof Joists and Rafters Problems
Joists are the parallel blocks of wood that run across the ceiling. Rafters, on the other hand, make up a roof’s framework and hold the shingles.
When these beams are improperly constructed, your roof will start to sag. Also, the beams can degrade due to wear and tear and in some cases weather. This causes them to strain to hold the weight of the roof, and eventually give up causing roof sagging.
Since fixing joists and rafters is quite extensive, have a roofing contractor fix the problem for you.
5. Old Age
When your roof has reached the end of its lifespan, it’s bound to start sagging. All those years of long exposure to harsh weather conditions will eventually wreck-havoc your roof. Shingles will crack causing water to seep in and reach the rafters. The end result is a sagging roof.
If your roof is nearing the end of its useful life, have it replaced. Proper roof maintenance also goes a long way into keeping your roof in good shape. So, be sure to schedule a maintenance routine.
Don’t Let a Sagging Roof Steal Your Home’s Curb Appeal
