Do It Right Roofing handles structural roofing needs for businesses across the South Sound. Flat roofs must manage consistent rainfall, which requires a clear understanding of how water moves across low-slope surfaces. As a commercial roofing contractor in Tacoma, we provide the local expertise needed to protect your facility.
Many commercial properties use low-slope roof designs to make space for rooftop units and simplify service access. To perform well in Washington’s climate, these roofs need membrane materials selected for moisture control and long-term exposure to weather.
Selecting Durable Materials for Local Weather
Do It Right Roofing offers single-ply membrane options that act as the main defense against water. Material selection depends on building use and exposure, and we guide owners in choosing systems suited for long-term performance.
Most commercial roofs rely on synthetic membranes built to handle standing water and UV exposure. These materials are lightweight yet durable, forming a continuous barrier across the roof deck.
The Benefits of TPO Membranes
Thermoplastic Polyolefin is commonly used for retail and warehouse roofs due to its reflective surface, which helps regulate indoor temperatures during warmer months. This single-ply membrane combines synthetic materials with a reinforcing layer to cover the roof.
Do It Right Roofing installs TPO using heat-welded seams that form a secure, watertight connection. These seams hold under stress and help limit leaks at joints, while the material resists mold and algae buildup.
PVC Roofing for Chemical Resistance
Polyvinyl Chloride is a roofing material often selected for commercial buildings, such as restaurants and industrial spaces, due to its ability to withstand exposure to oils, grease, and chemical discharge. This resistance helps preserve the membrane’s condition in demanding environments.
It also maintains flexibility through temperature shifts, allowing it to move with the structure without cracking or weakening. Do It Right Roofing suggests this system for properties that need consistent performance under challenging conditions.
EPDM Synthetic Rubber Options
Ethylene Propylene Diene Terpolymer is a rubber-based membrane known for its flexibility at low temperatures while maintaining long-term durability. It also withstands hail exposure and is installed in large sections to limit seam lines across the roof.
Do It Right Roofing installs EPDM using adhesives or mechanical fasteners based on the roof deck. This material provides a reliable moisture barrier and remains a practical option for large commercial projects.
Commercial Maintenance Schedule for the Pacific Northwest
Routine oversight is necessary to ensure that small issues do not escalate into major repairs. We follow a calendar that addresses the specific debris and moisture patterns found in this region.
| Month | Maintenance Task | Purpose |
| January | Clear drainage points | Prevent water from backing up during heavy winter storms. |
| March | Inspect for winter wear | Identify any splits or cracks caused by freeze and thaw cycles. |
| May | Surface cleaning | Remove dirt and biological growth that accumulated in the spring. |
| July | Seam evaluation | Check that all welded or glued joints remain tight in the sun. |
| September | Debris removal | Clear away fallen leaves and branches before the autumn rains. |
| November | Secure metal flashings | Ensure all edges are tightly sealed against high winds and moisture. |
Managing Drainage and Water Accumulation
Proper drainage is critical for flat roofs in wet climates. These systems rely on a slight pitch to guide water toward drains or scuppers, and Do It Right Roofing ensures these outlets remain clear.
Water that sits for extended periods can place stress on the roof deck and lead to sagging. We inspect drainage performance to confirm water moves off the surface efficiently.
Drain obstructions can cause water to build up and enter interior spaces in commercial buildings. Routine clearing of gutters and downspouts helps maintain proper flow and keeps moisture from collecting along the roof surface.
Preparing for Seasonal Temperature Changes
Seasonal shifts can strain commercial roofing materials as temperature changes cause expansion and contraction. Do It Right Roofing inspects transition points where the roof meets walls to ensure flashing remains secure.
Flashings seal edges and roof penetrations, making them common areas for leaks if they loosen. We maintain these areas with durable sealants to help prevent water intrusion during wind-driven rain.
Aging materials can become brittle and more vulnerable during colder conditions. We check for signs of wear, such as bubbling or thinning, to address issues before they lead to sudden repairs.
